2. Installation

Attention: Signal detection may be influenced by stray electric ａnd magnetic fields from other electrical appliances. Particularly intense disturbances are caused by computer terminals, fluorescent tubes ａnd ultrasonic cleaning equipment. The Q TEST 6000 therefore has to be set up at a sufficient distance from any such appliances or devices. Paging installations, too, may disturb signal detection.

2.1 MAINS SUPPLY

The Q TEST 6000 is supplied from the mains adapter unit with an output of 9 V~/12 VA. The mains adapter is available for nominal mains voltages of 230 V~(range 210 V~240 V~)or 120 V~(range 110 V~ TO 130 V).

BEFORE CONNECTING THE INSTRUMENT FOR THE FIRST TIME,CHECK THAT THE MAINS ADAPTER UNIT VOLTAGE CORRESPONDS TO YOUR MAINS SUPPLY VOLTAGE.

Use only an original Witschi mains adapter unit.

Connect the mains adapt unit to the 9 V~ socket for the mains adapter.

It takes about 3 minutes for the oven –controlled quartz time base to settle to its operational temperature when the instrument is initially connected to the supply.

Thereafter, the quartz time base remains constantly heated as long as the instrument is remains connected to the mains supply. The Q TEST 6000 is therefore always ready for use upon switching on.

If the device is not going to be used for lengthy periods(e.g. during holidays),we recommend unplugging the mains adapter from the mains supply.

2.2 PRINTER CONNECTION

Before connecting the printer (available as an option),remove the protection from the connector printer output. The appropriate interconnection cable is supplied with the printer.

WARNING! Before connecting the printer to the mains, check that the printer voltage corresponds to that of your mains supply.

2.3 SWITCHING THE DISPLAY OF THE RATE FROM SEC/DAY TO SEC/MONTH

Select the required unit for rate measurements by means of the slide-switch s/day s/month on the rear panel of the instrument.

2.4 TEST MODE SELECTION

The required test mode for the rate measurement is selected with the but in the TESTMODE RATE field of the front panel. The selected test mode is indicated by a LED. The letter(s) following the inscriptions by the LED’s refer to the sensor to be used.

The test mode for the module test is selected with the but in the TESTMODE MODULE field of the front panel.

The most frequently used test modes, quartz 32 kHz ａnd consumption ,are automatically selected when the instrument is switched on.

Detailed information concerning the various test modes is given in the following sections.

2.5 TEST PARAMETER SELECTION AND SETTING

Some of the test parameters may be changed by the user.

The required parameter is selected with the but in the PARAMETER field of the front panel. The current value of the parameter is shown by the PARAETER display. The parameter value can be incremented or decremented step-by step using the control knob.

All the parameters are set to the most common values ａnd the parameter supply voltage is displayed when the instruments is switched on.

countdown rate and countdown cons. are not variable parameters. In this case, the PARAMETER display shows the time remaining until the end of the currently running measurement sequence.

3 RATE MEASUREMENT-GENERAL INFORMATION

3.1 PRINCIPLE OF OPERATION

The sensor picks up a signal whose period depends on the rate variation of the watch. Depending on the test mode ,this can be the quartz oscillator frequency, the operating frequency of the LCD-display or the running frequency of the stepping motor.

The detected signal is amplified, filtered ａnd digitized. This signal is divided until its period approximately corresponds to the selected measuring time. The period of subdivided signal is measured against a highly accurate time base which serves as a reference. The difference between the measured period ａnd the reference period relative to zero deviation is calculated ａnd displayed in terms of s/day or s/month.

3.2 MEASURING PROCEDURE

The appropriate test mode is selected by means of the but in TESTMODE RATE field.

The watch is placed on the relevant sensor and, if necessary, moved or rotated until the respective Signal LED lights up clearly or flashes in synchronism with the watch pulses.

The measurement starts automatically as soon as a watch signal is detected. The result is displayed at the end of the measurement period. The measuring procedure continues as long as there is a detectable signal with the result being updated at the end of each measurement period. The transfer of a new result is indicated by a brief flashing of the display.

A currently running test sequence can be terminated ａnd a new cycle begun at any time by pressing the start test but.

The first measurement often provides an incorrect result because the watch was being moved at the start of the measuring process. In case of long measuring times, we recommend re-starting the measuring procedure once the watch has been properly positioned on the sensor. In this way the first measurement already provides a correct result.

Should the result be outside the measuring range of 10 s/day, the result H is displayed to indicate that the watch is running fast or L to indicate that it is running slow.

No value is displayed if the watch signal is far outside the measuring range or is disrupted that it cannot possibly be evaluated.

The value obtained remains on the display until the end of the current measuring period even if the watch is removed in the meantime.

3.3 TEMPERATURE EFFECTS

The rate of a quartz watch largely depends on the ambient temperature. It is therefore important that rate accuracy measurements are executed at room temperature or the normal working temperature on the wrist. In particular, comparative measurements must always be carried out at the same ambient temperature.

The accuracy of the Q TEST 6000 is not influenced by fluctuations in the ambient temperature.

3.4 TESTING OF WATCHES WITH DIGITAL TRIMMING(INHIBITION)

Erroneous measurements may occur when testing watches with digital trimming if the watchmaker is not familiar with their special characteristics which are explained below.

In the case of watches with digital trimming, the quartz oscillator frequency is not adjustable (no trimmer). A fixed capacitor within the IC itself is so dimensioned that the oscillator frequency for all quartzes is slightly too high. A programmable number of oscillator pulses is inhibited once per minute( or every 20 s, 30 s or every 2, 4 or 8 minutes in the case of some watches) during frequency division ,i.e., they are not transferred to the next divider stage.

The watch therefore runs slightly fast for 59 seconds as determined by the oscillator frequency ａnd extremely slowly during the second when the pulses are inhibited. The number of pulses that are inhibited is programmed so that the mean deviation is 0.As only a whole number of pulses can be inhibited at any one time, the adjustment is usually made in steps of 2/10 s per 24 h.

The programming of such watches is carried out by either selectively cutting traces on the printed circuit board of the watch or by a special pulse sequence applied to the battery connections of the IC.

If such a watch is measured by means of the quartz oscillator frequency, the result obtained constantly shows a tendency for the watch to be fast (normally between 1 to 10 s/day).

If the watch is measured over a period of 2 s on the basis of the motor pulses or the LED frequency, every 30 th. measurement would show a result that is extremely slow. The results of the rest of the measurements would be fast since they correspond to the oscillator frequency.

In order to obtain a correct result, such watches have to be measured by means of the stepping motor pulses. In this case, the measuring period has to be equivalent to the inhibition period or a multiple of it, that is, it has to be set to 20 s, 60 s, 120 s, 240 s or 480 s respectively.

4 RATE MEASUREMENT MODES

4.1 32 kHz QUARTZ TEST MODE

The mechanical or electrical oscillations generated by the quartz oscillator are sensed directly in the quartz 32 kHz mode. Both the acoustic ａnd capacitive sensors are active in this mode. The signal may also be sensed by way of the supply current.

The measuring period is 1 s ａnd cannot be altered.

Application

This method is suitable for testing all watches with a 32 kHz quartz frequency ａnd rate trimming of the oscillator (which applies to practically all watches with a trimmer).

Watches with digital trimming (inhibition) produce incorrect results (very fast) with the quartz testing method.

Sensors

The acoustic sensor (left sensor field) picks up the mechanical oscillations of the quartz crystal which are transferred through the case to the sensor pin. The watch therefore has to touch the sensor pin in the center of the sensor panel. The Signal quartz LED shows the intensity of the signal received. In the event of the signal being too weak, the watch should be moved or rotated on the sensor in order to find a better position for signal detection.

This sensor is particularly useful for watches in closed metal cases, but also be used for open modules. The sound of the stepping motor in analogue watches may disturb signal reception ａnd lead to unstable results. Should such instabilities occur, the stepping motor may be stopped by pulling out the watch crown.

The capacitive sensor (right sensor field) picks up the stray electrical field produced by the quartz oscillator. The Signal quartz LED indicates the intensity of the signal detected. In the event of the signal being too weak, the watch has to be moved or rotated slightly on the support , in order to improve signal reception. The capacitive sensor is suitable for open watch module s ａnd watches with plastic cases. The sensor is not suitable for watches with completely closed metal cases.

If the watch is powered from the Q TEST 6000, the oscillator frequency can be filtered out of the supply current. Rate measurement by means of the supply current only works in the measuring range. Because of the numerous disturbing signals in the supply current, the measurement may be somewhat unstable in which case a measurement by means of the motor current pulses will give a better result.

Attention: No other watch may be powered simultaneously if the watch is being tested on the acoustic or capacitive sensor.

4.2 LCD TEST MODE

The LCD test mode evaluates the working frequency of the LCD-display of a watch for measuring purposes. Any frequency may be used that is a quadruple of 4 Hz.

Application

This test mode is used for LCD watches which cannot be tested by means of quartz frequency, e.g. watches that run at a special frequency (such as timers ａnd calculators with a watch function) or watches with digital trimming.

Sensor

For testing purposes, the watch is put face downwards onto the capacitive sensor (right sensor field).

The signal LCD LED indicates the intensity of the signal received. If the signal is too weak, the watch should be moved or rotated on the sensor to improve its position for signal detection.

Measuring time

The measuring time is normally left at the initial value of 2 s. In the case of watches with digital trimming, this should be set to the equivalent of the inhibition period or a multiple of it.

In order to alter the measuring period, ｓelect the meas. time rate parameter ａnd set the required value with the rotary knob. The range extends from 2 s to 960 s.

The time left until the end of the current measurement period is indicated if the countdown rate setting is selected in the PARAMETER field.

4.3 STEPPING MOTOR TEST MODE (stepp. motor)

The stray magnetic field or the electrical current pulse of the motor coil is sensed in this test mode.

Application

This test mode may be used for all watches with a stepping motor. It is mainly used for watches which can otherwise only be measured with great difficulty or not at all by means of the oscillator frequency, e.g. watches with a special quartz frequency, watches with digital trimming or for watches where no stable result can be achieved in the quartz test mode.

Information: Practically any analogue watch can be tested in the stepp. motor test mode with a measuring time of 60 s, irrespective of the quartz frequency, the stepping period or the rate trimming principle. This setting may be universally used if the long measuring period is not disadvantageous.

sensor

The watch is placed on the magnetic sensor (right sensor field) for testing purposes. The Signal motor LED blinks for each motor pulse, thereby indicating the signal intensity. The watch should be moved slightly on the sensor if the signal is too weak.

Measurement by means of the current pulses

The motor pulses are filtered out of the supply when the watch is powered from the Q TEST 6000. Rate measurement by means of the supply current only works in the measuring range. To avoid the risk of other signals interfering, the magnetic sensor is automatically switched off as long as a supply current flows.

Attention: No other watch may be powered simultaneously if the watch is being tested on the magnetic sensor.

Measuring period

The measuring period has to correspond to the period of the stepping motor or a multiple of it. Watches with digital trimming (inhibition) have to be measured over an inhibition period or a multiple of it .The initial setting of 2 s is suitable for watches with 1 s steps ａnd a trimmer. A setting of 60 s is correct in most cases for inhibition watches.

In order to alter the measuring period, ｓelect the meas. time rate parameter ａnd set the required value with the rotary knob. The range extends from 2 s to 960 s.

The time left until the end of the current measurement period is indicated if the countdown rate setting is selected in the PARAMETER field.

4.4 MECHANICAL TEST MODE (mechanical)

In this test mode, the sound of the movement in a mechanical watch is evaluated for rate measurement purposes. Results are indicated in s/day.

Application

Mechanical watches running at 18000, 19800, 21600, 28800, or 36000 beats per hour may be tested with the Q TEST 6000. The instrument is ideally suitable for rapid testing of mechanical watches ａnd may also be used for adjustment purposes. For trouble shooting ａnd repairs, however, we recommend the use of an instrument with graphical recording (e.g. the WATCH EXPERT).

Sensor

The watch is placed on the acoustic sensor for testing purposes. The watch case has to touch the sensor pin. The Signal LCD LED indicates the signal intensity.

Measuring period

The measuring period is 4 s ａnd cannot be changed.

4.5 TUNING FORK TESTMODE (tuning fork)

The stray magnetic field of the tuning fork oscillator is sensed for tuning fork watches in this test method. Results are indicated in s/day.

Application

The watch is placed on the magnetic sensor for testing purposes. The Signal motor LED indicates the intensity of the signal received. The watch has to be moved around on the sensor field until an optimal signal intensity is achieved.

Measuring period

The measuring period is 4 s ａnd cannot be changed.

4.6 SPECIAL PROGRAMS FOR PROGRAMMABLE ICs (special program)

Various IC’s can be programmed or be quickly tested through the supply current.

1 Set the voltage to 1.55V in the PARAMETER field with supply voltage.

2 Select special program in the PARAMETER field. Use the rotary knob to set the program number, making absolutely sure that it is the correct number for the particular IC. The number is shown on the PARAMETER display. Any of the following numbers can be chosen:

P 1 for Philips IC’s series PCA 1400

P 2 for Philips IC’s series PCA 1460-1600

P 3 for MEM IC’s series H-1138,H-1140,H-1238,H-1138,H-1538

P 4 for MEM IC’s series H-1221,H-5222 SPL

3 Select quartz 32 kHz in the TESTMODE RATE field.

4 Make contact to the watch movement or electronic module by means of the movable probe arms. If a module holder type PM 6000 or a dummy battery is connected to the instrument, the watch movement can be powered alternatively through either of these.

5 Once the movement has been connected, check that the Signal quartz LED has lit up in ａnd that the frequency is shown on the RATE display. In the event of the signal being too weak (unstable or no rate display at all), ｓelect stepp. motor in the TESTMODE RATE ａnd set meas. time rate in the PARAMETER field.

6 Accelerated test. Briefly press ａnd then release the start test but in the TEST CONTROL field. The rate of the movement will now be displayed for a few seconds.

7 Program ａnd test the IC. Simultaneously press the buts start test ａnd print result for about 2-3 seconds ａnd then release both of them. The IC will be newly programmed, tested ａnd the rate of the movement displayed for a few seconds.

The module cannot be adjusted precisely to 0 since the adjustment is normally carried out in steps of 0.2 s. Adjustment is made as close as possible to 0 but always remains in the positive value range.

5 CURRENT CONSUMPTION MEASUREMENT

5.1 GENERAL INFORMATION

The current consumption of a watch provides information about the expected life of the battery ａnd is an important quality criterion for quartz watches.

In the case of analogue watches, the current is a combination of the IC current in the range of a few 100 nA ａnd peak loads during motor pulses of up to 1mA. The Q TEST 6000 registers the entire current by summing all portions of the current flow throughout the measuring period (integrating measurement). The result of this measurement provides the mean value of the entire current consumption (IC current ａnd motor current) throughout the measuring period.

The stepping motor can be switched off by pulling out the crown (possible with most watches) if only the IC current is to be measured.

The manufacturer’s data should be consulted for the maximum permissible current consumption of a watch.

Generally, the current consumption of the watch should be lower the smaller the battery is.

The typical current consumption of modern quartz watches amounts to between 1 ａnd 2 μA for analogue watches with 1 s/step ａnd for watches with longer stepping periods 0.5 up to 1.0μA.

5.2 CONTACT TO THE WATCH

To measure the current consumption ａnd the minimum working voltage, take the battery out of the watch ａnd power it from the Q TEST 6000 instead.

To make contact with the watch, fix it in the module holder ａnd place it on the glass window of the Q TEST 6000. The movable probe arms should be set to the points to be contacted ａnd pressed down far enough to depress the telescopic probes by about 1mm. The probes should be grasped at their rear ends to adjust the height.

The red positive(+) probe is placed on a point normally connected to the positive pole of the battery (battery case). The entire bottom plate is connected to the positive pole in most watches.

The black negative (-) probe is placed on a point normally connected to the negative pole of the battery (battery lid). The contact spring for the negative battery connection is usually the most accessible point in the majority of watches.

The two LED’s open ａnd short give an immediate indication of having made successful contact. Both LED’s are extinguished as soon as correct contact has been established. If the circuit is open, the open LED lights up. The short LED lights up in the case of a short circuit or wrong polarity.

The watch hands can be observed in the mirror below the window. If the watch runs the contacts are in order.

Attention: Although the maximum supply current is limited to 3mA in the μA range, the watch may be damaged by contacting the wrong points or applying the wrong polarity.

In the case of clocks, the module supply is best connected with the help of the measuring leads ａnd crocodile clips.

5.3 SUPPLY VOLTAGE

When the supply voltage parameter is selected, the PARAMETER display indicates the voltage at the test socket, which may then be changed within the range from 0 to 3.5 V by turning the knob.

Current consumption measurements should be effected with the nominal battery voltage which has the following values for the various battery types:

5.4 MEASURING PERIOD

To ensure an accurate measurement of the mean current consumption, the measuring period in the case of analogue watches has to be equivalent to a stepping period or a multiple of it.

The currents for the positive ａnd negative motor pulse are often unequal which can cause small fluctuations when the measuring time is only based on a single stepping period.

A measuring time of 1 s is sufficient for LCD watches.

To set the measuring period, ｓelect the meas. time cons. parameter ａnd set the measuring period to the required value by means of the adjustment knob. The range extends from 1 to 60 seconds.

The time left until the end of the current measurement period is indicated if the countdown cons. setting is selected in the parameter field of the front panel.

5.5 THEμA MEASURING RANGE (consumption μA )

consumption μA consists of the 100μA (10 nA resolution) ａnd 1000 μA (100μA resolution) measuring ranges with automatic range selection. Peak loads of up to 2 mA may be correctly measured in this test mode. Current limitation limits the maximum supply current to about 3mA.

Application

The current consumption of any type of quartz watch can be measured in this test mode. Rate measurement by means of the supply current is possible only under these circumstances.

Neither lamps for LCD-displays nor alarm buzzers may be operated in this test mode.

5.6 THE mA MEASURING RANGE (consumption mA)

consumption mA consists THE 10 mA (1 μA resolution) ａnd 20 mA(10 μA resolution )measuring ranges. The maximum supply current is limited to about 50 mA.

Application

Measurement of the current consumption of watch alarms ａnd lamps for LC-displays. Rate measurement by means of the supply current is impossible in this test mode.

6 STARTING VOLTAGE

The minimum operating or starting voltage is an indicator of the power reserves of the watch ａnd the capacity to continue running in spite of an almost exhausted or heavily loaded battery (LCD watches with the light switched on).

In order to measure the starting voltage, supply power to the watch as explained in Section 5. While observing the hands of the watch in the mirror, reduce the supply voltage until the watch stops, then slowly increase it once more until the watch starts running again.

Normally it is sufficient to check that the watch runs correctly at .a reduced supply voltage. The minimum supply voltage usually in the order of 1.25 V in the case of watches with a silver oxide battery.

7 BATTERY TEST

7.1 GENERAL INFORMATION

The voltage of a watch battery remains constant almost to the end of its life ａnd only drops when it is fully run down. The test, even under load, only shows whether the battery is still usable or entirely exhausted. No information concerning the remaining battery life can be derived.

The battery should also be checked for leaks during the test. The battery must be replaced if salt crystals are visible between the case ａnd lid even though the voltage may still be high enough.

The polarity of the battery must be observed when testing. Generally speaking, the case of a battery for a wrist watch is normally the positive (+) pole ａnd the lid is the negative (-) one.

Conversely, the case serves as negative pole ａnd the contact on the lid as the positive one for clock batteries ａnd lithium batteries.

For testing purposes, the battery has to be placed on the battery support in the BATTERY TEST field on the front panel with its positive side downwards ａnd contacted at the negative pole by the black test probe or the black measuring lead.

The battery may also be checked directly in the watch with the help of the measuring leads.

The measured battery voltage is displayed in the MODULE panel field.

7.2 BATTERY LOAD

Loading the battery with a load resistor shows whether it can supply the necessary current without the voltage dropping out of tolerance.

The basic load without activating any buts amounts to about 2μA. This load corresponds approximately to the current consumption of a watch. The battery should not show any substantial voltage drop.

A load of 1kΩcan be switched on by pressing low drain but. This load corresponds approximately to the peak load during a motor pulse.

A load of 100Ω may be added by pressing the high drain but. This load corresponds approximately to the current drawn when the light in an LCD watch is activated. The 100Ω load is only practicable for high drain ａnd clock batteries. The but should not be pressed for longer than necessary otherwise the battery will be quickly drained.

8 RESISTANCE MEASUREMENT

8.1 GENERAL INFORMATION

The resistance measuring range is predominantly used for the location of open or short circuits in the motor coil of analogue watches or insulation defects between coil ａnd coil core or mounting plate.

Resistance measurements are also useful for continuity ａnd insulation testing of connections, circuits ａnd switches.

The measurement is made with a constant voltage of 0.3 V. With this low test voltage, components which are connected to an integrated circuit can also be checked without falsifying the result. The measuring range extends from 15Ω to 5 MΩ with automatic ranging.

The battery has to be taken out of the watch for all resistance measurements.

Contact to the measuring points is effected by using the movable probe arms or measuring leads.

8.2 COIL RESISTANCE AND COIL INSULATION

Coil resistance

The two coil connections on the watch module are contacted for the measurement of coil resistance. Polarity is unimportant.

The resistance value in the case of analogue watches is normally between 1kΩ ａnd 3kΩ. Please consult the watch manufacturer’s data for more precise values.

A break in the coil is indicated by the H display ａnd by the open LED lighting up.

Insulation

one of the two coil connections ａnd the mounting plate of the watch have to be contacted to test the coil insulation. A break is indicated if the insulation is good (H display ａnd the open LED lights up). A low resistance value is indicated in the case of defective insulation.

8.3 CONTINUITY AND INSULATION TEST

Observation of the two LED’s, short ａnd open, suffices for continuity ａnd insulation tests on arbitrary watch components.

If the short LED lights up the two test points are interconnected ａnd if the open LED lights up they are insulated from one another. The resistance value may be read on the display if there is no LED signal.

9 PULSE GENERATOR

9.1 APPLICATION\

The stepping motor ａnd the mechanical parts of analogue quartz watches can be tested independently of the IC in the pulse generator test mode.

The pulse generator supplies bipolar pulses with adjustable voltage ａnd pulse width. The pulse repetition frequency is either 8 or 16 Hz depending on the pulse width selected.

The battery has to be taken out before the test is carried out. The watch is fixed in the module holder ａnd placed on the glass window. The coil connections are contacted with the two probes. Correct operation of the watch can be checked in the mirror.

The pulse generator function provides no numerical results.

9.2 PARAMETER SETTING

Pulse voltage

The pulse voltage can be set when the supply voltage parameter is selected. Under normal conditions , the pulse voltage is 0.1 to 0.2 V lower than the actual battery voltage due to the voltage ｄrop across the output transistors. The pulse voltage should be appropriately adjusted to ensure that the operation with the pulse generator is subject to the same conditions.

Pulse width

Select the pulse width parameter to set the pulse width which can be adjusted with the rotary knob. The PARAMETER display window shows the pulse width in ms. The pulse frequency is 16 Hz for pulse widths below 16 ms ａnd 8 Hz for those above 16 ms.

The correct pulse width has to be set to accord with the data from the watch manufacture. The standard pulse width of 6.8 ms may be taken for a simple function test if the correct pulse width is not known.

Chopped pulses

The pulse generator in the Q TEST 6000 supplies no chopped pulses. Such pulses can, however, be simulated to a large degree by reducing the pulse voltage in proportion to the chopp ratio.

10 ALARM TEST

The Q TEST 6000 supplies a test frequency of 2 kHz in the alarm test mode to test the magnetic or piezoelectric alarm buzzer in a watch.

The voltage can be set with the supply voltage parameter.

11 TROUBLE SHOOTING FOR QUARTZ WATCHES

The following notes contain some recommendations to watchmakers, on how to locate defects in quartz watches both quickly ａnd reliably.

11.1 SYSTEMATIC TROUBLE SHOOTING

Proceed as follows to localize a defect quickly in a quartz watch that is not running:

• Place the watch on the acoustic sensor ａnd check to see whether any signal exists (quartz LED lights up). Check the battery if there is no signal.

• If the battery is found to be in order ａnd the quartz signal is indicated, test the resistance ａnd insulation of the motor coil.

• If the coil is in order, place the watch on the magnetic sensor ａnd check whether there are any motor pulses (motor LED lights up with each pulse).

• If the watch passes all of the above checks, there must be a mechanical defect, such as: hands catching, blocked or extraneous matter in the movement, fine steel particles on the rotor magnet, etc.

11.2 BATTERY

Whatever the defect, check the battery first (see Sections 7⁻⁷.3). Remove any dirt or oxidation from the battery contacts ａnd bend the contact springs back into shape as necessary.

11.3 IC DEFECTS

Oscillator test

In the quartz 32 kHz test mode, the quartz LED shows whether the quartz oscillator is functioning ａnd whether the 34 kHz signal is present. If no signal is displayed, either the quartz crystal, the trimmer or the integrated circuit (IC) is defective.

Testing the motor driver stage

The motor LED lights briefly with each motor pulse in the consumption μA test mode. If there is no signal in spite of the fact that the motor coil is in order, then the following applies:

• either the IC is defect, or

• the reset remains activated although the hands setting stem is pressed in (defective mechanism, stem too short).

11.4 MECHANICAL DEFECTS

If a watch runs very slow or does not run at all, although the electronic module ａnd motor coil are perfectly operational, the cause is to be sought in the mechanics of the watch. Possible defects are:

• Steel particles adhering to ａnd blocking the rotor magnet. Small chips can be set free as the case bottom is screwed or snapped on.

• The mechanism does not run freely or is completely blocked. Small particles in the gears may partially or even entirely block the movement. Test for free running ａnd cleanliness.

• Check whether the hands catch, or touch the glass or face.

• The “reset by stem” mechanism is defective. When the hands setting stem is pulled, the seconds hand is mechanically blocked ａnd the reset contacted. The mechanism should not touch the seconds gear wheel when the hands setting stem is pressed in ａnd the reset contact must be opened. This fault occurs if the mechanism is defective or the stem is too short.

11.5 LCD-DISPLAYS

No display on an LCD watch.

• First test the battery.

Place the watch on the acoustic sensor ａnd ｓelect the quartz 32 kHz test mode.

• If the quartz LED does not light up, either the quartz crystal, the trimmer or the IC is defective.

• If the quartz LED lights up, the IC or the display is defective.

The LCD display lacks several segments.

Possible faults:

• Insufficient contact between the printed circuit ａnd the display; carefully clean the contact

pads ａnd contact strips;

• IC or display defective.

12 PM 6000 MODULE HOLDER

The PM 6000 module holder is an accessory for the serial testing of watches. It does not belong to the standard equipment supplied with the Q TEST 6000.

5.电流消耗测试
5.1 一般说明
手表的电流消耗可提供有关电池预计寿命方面的资讯，同时也是石英手表的一项重要质
量指标。
对于石英手表，其电流是范围约为数百纳安的集成电路电流与可达1 毫安的电机脉
冲期间的峰值电流的复合电流。QT-8000B 通过在整个测试周期内叠加各部分的电流而
记录整个电流(积分测量)。该测量的结果提供整个测试周期中的总电流消耗的平均值(集
成电路电流及电机电流)。
如果只测量集成电路的电流，则可将手表的把杆拉出而停止步进电机(适用于多数手
表)。
手表的允许电流消耗可咨询制造商的数据。
一般来说手表的电池越小，手表的电流消耗也应越小。
1 秒/步进的现代石英手表的典型电流消耗在1 至3 微安之间，步进周期更长的手表的典
型电流消耗在0.5 至高达1.5 微安之间。
5.2 手表接点
测量电流消耗及小工作电压时，将电池从手表中取出并利用QT-8000B 为手表供电。
与手表接触时，将手表固定于机芯座内并将机芯座放入QT-8000B 的玻璃窗内。可移动
探头臂应设定于接触点处，并应充分向下压动使套管探头压下约1 毫米。调整高度时应
握持探头的后端部。
将红色正极(+)探头放置于一般连接电池正极的接点处(电池外壳)。在多数手表中，整
15
个基板一般与正极接触。
将黑色负极(-)探头放置于一般连接电池负极的接点处(电池盖)。在大多数手表中，连
接电池负极的接触弹簧一般是容易连接的接点。
二个开路及短路发光二极管将立即闪亮表明已成功接触。二个发光二极管在确立正确接
触后将立即熄灭。如果电路开路，开路发光二极管将闪亮。如果短路或极性连接不正确，
短路发光二极管将闪亮。
手表表针可从玻璃窗下的反光镜中观察。如果手表走动，说明接点正确。
警告：虽然微安量程中电源电流限定为3 毫安，但如果接触点连接不正确或极性连
接不正确，手表可能会因此而受损。
对于钟类，使用测量引线及鳄鱼夹可以很容易地连接机芯。
5.3 供电电压
选择供电电压参数后，参数显示器显示测试插座处的电压，之后旋转旋钮可以在0 至
3.5 伏的范围内改变该电压值。
电流消耗测量应使用标准的电池电压进行，各种电池的电压如下：
氧化银电池(标准手表电池) ： 1.55 伏
纽扣电池(较老的型号) ： 1.35 伏
锂电池(新型，目前尚较少使用) ： 2.00 伏
氧化锌电池或碱电池(用于钟表) ： 1.40 伏
5.4 测试周期
为了地测量平均电流消耗，对于石英手表，测试周期应设定为步进周期或步进周期
的倍数。
正负电机脉冲的电流常常互不相同，如果测试时间只为单个步进周期时，测试结果会有
16
一些小的波动。
对于液晶显示手表，1 秒钟测试时期即已足够。
设定测量周期时，选择测试时间消耗参数并利用调整旋钮将测试周期设定为所需的数
值。设定范围为1-60 秒钟。
如果在面盘的参数区域内选择了倒计数消耗设定，系统将显示至当前测试结束时的剩余
时间。
5.5 微安测试范围(消耗微安)
消耗微安包括100 微安(10 纳安分辨率)和1000 微安(100 纳安分辨率)二个测试范围，量
程由系统自动选择。该测试方式可正确测试高达2 毫安的峰值负载。电流极限将供
电电流限定于约3 毫安。
应用
该测试方式可以正确测定任何石英手表的电流消耗。只有在该方式下才可能利用供电电
流方式进行快慢(走时精度)测量。
在该方式下，液晶显示器指示灯或响闹蜂鸣器均不可操作。
5.6 毫安测试范围(消耗毫安)
消耗毫安包括10 毫安(1 微安分辨率)和20 毫安(10 微安分辨率)测试范围。供电电
流约限定于50 毫安。
应用
用于测试手表响闹及液晶显示器照明灯的电流消耗。
在该测试方式下，不能利用供电电流进行快慢(走时精度)测试。
17
6.启动电压
工作或启动电压是衡量手表的电源储备以及电池几乎耗尽或在电池负载过大时(如
点亮照明灯时的液晶显示手表)继续工作的能力的指标。
为了测量启动电压，根据第4 章的介绍连接手表电源。在反光镜中观察表针走动的同时，
降低电压直到手表停止走动，然后慢慢增加电压直到手表开始再次走动。
正常情况下，仅检查在降低后的供电电压下手表是否可以正常工作即可。使用氧化银电
池的手表的小供电电压一般在1.25 伏的数量级。

7.电池测试
7.1 一般说明
手表电池的电压在几乎接近电池寿命的终点时仍可保持恒定，并仅在电池完全耗尽时才
会下降。甚至可在接有负载的情况下进行的这一测试仅用来判明电池是否仍然可用或是
否已完成放电。无法得到有关电池剩余寿命一类的咨询。
在电池测量过程中，亦应检查电池是否有泄漏。在电池外壳及电池盖之间的密封处有结
晶盐出现时，即使电池电压仍足够高，也应更换电池。
测试过程中，应注意电池的极性。一般而言，手表电池的外壳一般为正极(+)，电池盖
一般为负极(-)。
相反，对于钟用电池及锂电池，电池的外壳为钢板，而电池盖上的接片则为正极。
测试时，应将电池放置于面盘上电池测试区域中的支托内，使电池的正极向下，电池负
极与黑色探头或黑色测试引线接触。
18
利用测试引线也可以在手表内直接测试电池。
测得的电池电压在机芯面盘区域内显示。
7.2 电池负载
利用负载电阻使电池加载可表明电池是否可以提供所需的电流而又不产生超出误差范
围的电压降。
在不按下任何按键时的基本负载为 2 微安，这一负载大约与手表的电流消耗相对应。在
这一负载下，电池应不呈现出明显的电压降。
按下低消耗按键可接通 1 千欧姆的负载。该负载大约与电机脉冲的峰值电流相对应。
按下高消耗按键可增加 100 欧姆的负载。这一负载大约与液晶显示手表的照明灯点亮时
的电流相对应。100 欧姆的负载仅实用于高消耗电池及钟表电池。除非需要，请不
要按下该按键过长的时间，否则电池将很快放电。
7.3 标准电池电压
氧化银电池，1 千欧姆负载(低消耗)
电池良好 1.45 至1.55 伏
电池寿命终结 低于 1.20 伏
氧化银电池，100 欧姆负载(高消耗)
电池良好 1.25 至1.50 伏
电池寿命终结 低于 1.20 伏
纽扣电池，1 千欧姆负载(低消耗)
电池良好 1.25 至1.35 伏
电池寿命终结 低于 1.20 伏
钟用电池，100 欧姆负载(高消耗)
电池良好 1.30 至1.50 伏
19
电池寿命终结 低于 1.20 伏
锂电池，无负载
电池良好 1.90 至2.30 伏
电池寿命终结 低于1.80 伏

8.电阻测量
8.1 一般说明
电阻测量方式仅用于确定石英手表中电机线圈中的开路或短路的位置或线圈与线圈芯
或安装基板间的绝缘缺陷。
电阻测量对于连接点、电路及开关的连续性及绝缘测试也非常有用。
测量使用恒定的 0.3 伏电压进行。利用这一低测试电压还可以测量与集成电路连接的部
件而不至于产生谬误的结果。
测量范围为 15 欧姆至5 兆欧姆，量程可自动切换。
在所有的电阻测量中，应将电池从手表中拆除。
利用可移动探头臂或测量引线实现与测试点的连接。
8.2 线圈电阻及线圈绝缘
线圈电阻
接触手表机芯上的二个线圈接点以进行线圈电阻测量。这里极性并不重要。
对于石英手表，电阻值一般在1 千欧姆至3 千欧姆之间。数值请参照制造商的数据。
线圈开路由 H 显示及开路发光二极管指示。
绝缘
20
进行线圈绝缘测试时，应接触二个线圈接点之一及安装板。绝缘良好时显示开路(H 显
示极开路发光二极管闪亮)。绝缘有缺陷时由低电阻值指示。
8.3 连续性及绝缘测试
观察短路及开路二个发光二极管足以检查任意手表部件的连续性及绝缘性。
如果短路发光二极管闪亮，说明两个测试点之间短接。如果开路发光二极管闪亮，说明
二个测试点彼此绝缘。没有发光二极管信号时，可以从显示器其中读取电阻值。
9.脉冲发生器
9.1 应用
在脉冲发生器测试方式下，石英表的步进电机及机械部件可以不依赖于集成电路而单独
测试。
脉冲发生器提供电压及脉冲宽度可调的双极脉冲。依选择的脉冲宽度的不同而不同，脉
冲重负频率可为8 或16 赫兹。
在测试开始前，应将电池从手表中取出，将手表固定在机芯座上并放入玻璃窗内。利用
二个探头接触线圈的连接点。手表的正确运转情况从反光镜中观察。
脉冲发生器功能不提供数字化结果。
9.2 参数设定
脉冲电压
在选择供电电压参数后，可以设定脉冲电压。由于穿过晶体管的电压降，脉冲电压比实
际的电池低0.1 至0.3 伏。脉冲电压应经适当调整以确保在相同的条件下操作脉冲发生
器。
21
脉冲宽度
选择脉冲宽度参数以设定脉冲宽度，脉冲宽度可用旋钮调节。参数显示窗以毫秒为单位
显示脉冲宽度。脉冲宽度低于16 毫秒时脉冲频率为16 赫兹，高于16 毫秒为8 赫兹。
应设定正确的脉冲宽度以适应手表制造商的数据。如果不知道正确的脉冲宽度，对于简
单的功能测试可以采用标准7.8 毫秒的脉冲宽度。
阴影脉冲
QT-8000B 内的脉冲发生器不提供阴影脉冲。但相对阴影比成比例地减少脉冲电压可以
在很大程度上模拟此类脉冲。
10.响闹测试
在响闹测试方式下，QT-8000B 可以提供2 千赫的测试频率用于测试手表中的磁性或电
压蜂鸣器。
电压大小可利用供电电压参数设定。

11.石英手表故障排除
以下附注为手表制造商提供如何快速可靠地查找石英手表中的缺陷的有关建议。
11.1 系统缺陷排除
可以采取以下步骤快速地确定已停走的手表中的故障：
● 将手表放置在音频传感器上并检查是否有任何信号(石英发光二极管闪亮)。如果没
有信号，请检查电池。
● 如果电池良好并有石英信号指示，请检查电机线圈的电阻和绝缘。
● 如果线圈良好，将手表装置在磁性传感器上并检查是否有电机脉冲(对于每一个电
机脉冲电机发光二极管将闪亮)。
● 如果手表成功地通过了上述所有测试，则手表故障应该是机械故障，如表针锁住、
22
手表机芯内有障碍或多余物以及转子磁石中进入了细小的金属颗粒等。
11.2 电池
出现故障时，无论故障为何，首先应检查的是电池(参见第7 章)。
清除电池接点上的污物或氧化物并在需要时将接点弹簧折回原来的形状。
11.3 集成电路缺陷
振荡器测试
在石英 32 千赫兹测试方式下，石英发光二极管可显示石英振荡器是否工作以及32 千赫
兹信号是否存在。如无信号显示，则：石英晶体、微调器或集成电路中有故障。
电机驱动器及测试
在消耗微安测试下，对于每一个电机脉冲，电机脉冲发光二极管将快速闪亮。如果尽管
电机线圈良好而仍无信号时，则：
● 集成电路有缺陷。
● 在把的杆压下后手表仍处于复位状态(机构故障、把的杆太短)。
11.4 机械故障
如果手表走的很慢或根本不走，而电子线路板及电机线圈工作正常，则应从手表的机械
部分查找故障。可能的缺陷包括：
● 钢质颗粒粘附于并阻止了转子磁石。金属外壳底盖在旋紧或扣紧时很容易脱落小
的颗粒。
● 机械件不能自由运行或已完全受阻。齿轮上累积小粒子可部分或完全阻止机芯。
可进行自由运行及清洁检查。
● 检查表针有无咬合或接触玻璃或表面。
● “复位把的杆” 有缺陷。在把的杆拉出后，秒针将被机械锁定，复位接触关闭。
23
在把的杆推入后，其机构不应接触秒针齿轮，复位接触应打开。在机构内有缺陷
或把的杆太短时会出现这一故障。
11.5 液晶显示器
液晶显示手表上无任何显示：
首先检查电池。
将手表放置在音频传感器上，并选择石英 32 千赫兹测试方式。
● 如果石英发光二极管不闪亮，则石英晶体、微调器或集成电流中有缺陷。
● 如果石英发光二极管闪亮，则集成电路或显示器有故障。
液晶显示缺少某一显示段：
可能的故障包括：
● 印制板与显示器间接触不良。请仔细清洁接触片及接触条。
● 集成电流或显示器缺陷。

3.4 配有数字微调(抑止INHIBITION)的手表的测试
如果手表制造商不了解其特有的特性，对于配有数字微调的手表的测量可能会给出错误
的结果，现将此类手表的特有特性介绍如下：
对于配有数字微调的手表，石英晶体震荡器的频率是不可调的(无微调器)。集成电路内
的固定电容器的电容值经设定使得所有石英振荡器的频率都稍微偏高。在频率分割期
间，在每一分钟内对一组可编程数目的振荡器脉冲进行一次抑止(或者对于某些手表，
在每20 秒或8 分钟内进行一次抑止)，即他们将不会被传递到下一个分频阶段。
手表因此在由振荡器频率确定 59 秒钟内依稍快的速度运行，而在脉冲抑止的1 秒钟内
则运行的极为缓慢。抑止脉冲的数目经编程使得平均偏差为零。由于在任何给定的时刻
只可抑止一组数目的脉冲，调整一般以每24 小时2/10 秒的间隔进行。
此类手表的编程可选择使用切割手表印制板上的敷铜片或使用施加于集成电路电池连
接处的特殊脉冲序列来实现。
如果利用石英振荡器频率的方式来测量此类手表，测量结果总会显示手表快走的趋势
(一般在1 至10 秒/天之间)。
如果根据电机脉冲或液晶显示器频率在 2 秒钟的周期内对手表进行测量，每进行的第
30 次测量总会给出极慢的结果。测量的其余结果会是快速的，因为他们与振荡器频率
相对应。
为了得到正确的结果，此类手表应利用步进电机脉冲的方式测量。在这种情况下，测量
周期应等于抑止周期或抑止周期的倍数，即测量周期应分别设定为20、60 秒或8 分钟。

4.快慢(走时精度)测试
4.1 32 千赫石英测试方式
在32 千赫测试方式下，仪器直接测量由石英振荡器产生的机械或电震荡。在这一测试
方式下，音频及电容传感器均处于工作状态。信号检测也可以通过电源电流进行。
测量周期为 1 秒钟，且不可改变。
应用
该方法适用于测试所有具有 32 千赫石英频率及振荡器快慢(走时精度)微调的手表(尤其
适用于所有配有微调器的手表)。
由于其较短的测量周期，该方法是进行微调器调整的理想方式。
利用适应测试方法测量配有数字微调(抑止 INHIBITION)的手表会给出不正确的结果
(手表走动的极快)。
传感器
音频传感器(左侧传感器区域)检测通过表壳传递给传感器探针的石英晶体机械震荡。因
此，手表应接触传感器面盘中央的传感器探针。石英信号发光二极管指示接收信号的强
度。在信号太弱时，应在传感器上移动或转动手表以寻找理想的信号检测位置。
该传感器尤其适用于密封金属外壳的手表，但也可以用于测试开放机芯。石英手表中步
进电机发出的声音会干扰信号接收并导致不稳定的结果。在发生类似的不稳定性时，拉
出手表调节轴可使步进电机停止走动。
容性传感器(右侧传感器区域)检测由石英震荡器产生的杂散电场信号。石英信号发光二
极管指示检测信号的强度。在信号太弱时，应在支托上轻微移动或转动手表以改善信号
接收。容性传感器适用于测试开放手表机芯以及配有塑料外壳的手表。该传感器不适用
10
于配有完全密封金属外壳的手表。
如果手表由 QT-8000B 供电，则振荡器频率可以从电源电流中滤波得到。利用电源电流
进行的快慢(走时精度)测试仅适用于测试范围A。由于电源中的各种干扰信号，测试可
能会有一些不稳定，这时使用电机电流脉冲进行测试会给出较好的结果。
注意：在音频或容性传感器上进行手表测试时，其他手表不可同时由系统供电。
4.2 液晶显示器测试方式
液晶显示器测试方式为测量目的而测试手表的液晶显示器的工作频率。可以使用4 赫兹
4 倍数的任何频率。
应用
该测量方式适用于测量那些不能利用石英振荡器频率进行测量的液晶显示器手表。例
如，以特殊频率运行的手表(如秒表及配有计时功能的计算器等)或配有数字微调的手表
等。
传感器
为测试目的，手表应面向下放置于容性传感器上(右侧传感器区域)。
液晶显示器发光二极管指示接收信号的强度。如果信号太弱，应移动或转动手表以改善
其信号检测的位置。
测试周期
测试周期一般设定为 2 秒/的初始值。对于配有数字微调的手表，测试周期设定为抑止
周期或其倍数。
要改变测试周期时，可选择测试时间快慢(走时精度)参数并用旋钮改变其数值。时间范
围为2-980 秒。
11
在面盘的参数区域内选择倒计时快慢(走时精度)设定后，显示器将显示到当前测试周期
结束时的剩余时间。
4.3 步进电机测试方式
在该测试方式下，系统检测电机线圈的杂散磁场或电流脉冲。
应用
该测试方式可用于测量所有配有步进电机的手表。它主要用于很难测量的手表，或利用
振荡器频率根本无法测量的手表，例如特殊石英频率的手表、配有数字微调或在石英测
试方式下测试无法得到稳定结果的手表等。
注：实际上，任何石英手表都可以用 60 秒的测试周期在步进电机方式下进行测试而不
管其石英频率、步进周期或快慢(走时精度)微调原理为何。如果可容忍较长的测试周期，
则该设定可以广泛地应用。
传感器
为测试目的，将手表放置于磁性传感器上(右侧传感器区)。对于每一个电机脉冲，电机
测试方式发光二极管闪烁指信号的强度。信号太弱时，应轻微移动或转动手表。
利用电流脉冲进行测量
在手表利用 QT-8000B 供电时，电机脉冲将从电源电流中滤波得到。利用电源电流进行
的快慢(走时精度)测试只可在测量范围内操作。为避免其它信号的干扰，只要有电源电
流流动，磁性传感器将自动关闭。
注意：利用磁性传感器进行测试时，其它手表将不能同时由系统供电。
测试周期
测试周期应对应步进电机的周期或其倍数。配有数字微调(抑止 INHIBITION)的手表应
在抑止周期或其倍数间测试。初始2 秒钟的设定适用于1 秒步进及配有微调器的手表。
12
在大多数情况下，60 秒的设定适用于所有的抑止类手表。
要更改测试周期时，选择测试时间快慢(走时精度)参数并使用旋钮设定所需的数值。数
值范围为2-960 秒。
如在面盘参数区域内选择了倒计数快慢(走时精度)设定，则显示器将显示至当前测试周
期结束时的剩余时间。
4.4 机械测试方式
（该测试方式需求购置外接音频传感器）在该测试方式下系统将测定机械表中的机械运
动声音以测定其快慢(走时精度)。结果以秒/天为单位显示。
应用
以每小时 18000、19800、21600、28800 或38000B 次节拍运行的机械手表可以利用
QT-8000B 进行测试。该仪器适用于机械手表的快速测试，并可用于调整目的。但对
于故障排除及维修目的，我们建议使用具有图形记录功能的测试仪(如维时MTG-3000、
MTG-5000)。
传感器
为测试目的，手表将放置于音频传感器上。手表外壳应接触传感器的探针。液晶显示器
信号发光二极管指示信号的强度。
测试周期
测试周期为 4 秒且不可改变。
4.5 音叉测试方式
在这一测试方式下，系统将测试音叉振荡器的杂散磁场。结果将以秒/天为单位显示。
13
应用
为测试目的，将手表放置于磁性传感器上。电机信号发光二极管指示接收信号的强度。
应在传感器区域内移动手表直到得到的信号强度。
测试周期
测试周期为 4 秒且不可改变。
4.6 可编程集成电路特殊程式
使用本仪器，可以通过电源电流对各种集成电路编程或进行快速测试。
1) 将“电源电压”参数区域内的电压设定为 1.55V。
2) 在参数区域内选择“特殊程式”。利用旋钮设定程式号码，应确保特定集成电路
的正确号码。号码将在参数显示器上显示。可以选择任何下列号码：
P1 菲利浦集成电路系列PCA 1400。
P2 菲利浦集成电路系列PCA1460-1600。
P3 MEM 集成电路系列H-1138、H-1140、H-1238、H-1338、H-1538。
P4 MEM 集成电路系列H-2332、H-5222SPL。
3) 在快慢(走时精度)测试方式区域内选择“石英32 千赫”。
4) 利用可移动探测臂接触手表的机芯或电子线路板。如果仪器连接有 PM8000B 型机
芯座或电池，则手表的机芯可以利用二者之一供电。
5) 连接机芯后，检查确认信号区域内的“信号”发光二极管已闪亮并且快慢(走时精度)
显示器以显示频率。在信号太弱时(不稳定或根据无数据显示)，在快慢(走时精度)
测试方式中选择“步进电机”并设定参数区域内的“测试时间快慢(走时精度)”。
6) 加速测试。轻轻压下并释放测试控制区域内的“开始测试”按键。这时机芯的快慢(走
时精度)将显示数秒钟。
7) 编程并测试集成电路。同时压下“开始测试”及“打印结果”按键2-3 秒钟并释放。
这时集成电路将被编程、测试，机芯的快慢(走时精度)将显示数秒钟。
由于调整一般是以 0.2 秒的递增量进行，因此手表电子板不被地设定为0。调整将
尽可能地接近0，但总会处于正直范围内。

3.快慢(走时精度)测试 – 一般说明
3.1 工作原理
信号传感器检测周期取决于手表快慢(走时精度)变化的信号。依测试方式的不同而不
同，该信号可以是石英晶体振荡器频率、液晶显示器的工作频率或者是步进电机的工作
频率。
接收信号经放大、虑波后进行数字化处理。数字化后的信号将进一步的分割直到其周期
长度约与选择的测试周期长度相对应。分割后的信号周期将依高精度时基为参照进行测
量。周期测量长度与零偏离基准周期之差经计算后以秒/天或秒/月为单位显示。
7
3.2 测试步骤
待测手表的适当的测试方式利用面盘上快慢(走时精度)测试区域中的按键选择。
将手表放置在对应的传感器上，并在必要时移动或旋转手表使相应的信号发光二极管清
洗的闪亮与手表脉冲同步闪烁。
在检测到手表信号后测试将立即自动开始。测试结果在测试周期结束时显示。只要有可
检测的信号，测试过程将继续进行，测试结果在各周期结束时进行更新。显示器快速闪
动表示在进行新结果切换显示。
按下开始测试按键可随时终止当前进行的测试程式并开始新的测试。
由于在测试过程开始时手表仍处于移动中，项测试常常给出不正确的结果。
对于较长的测试时间，我们建议在手表正确定位于传感器上后再次重新开始测试步骤。
在测试结果超出 10 秒/天的测试范围时，显示器显示结果H，指示手表进行过快，或显
示L 指示手表进行过慢。
如果手表信号远远超出测试范围或在手表信号遭受严重干扰无法评测时，显示器将无结
果显示。
甚至在手表中途移开后，测试结果仍将持续显示直到当前进行的测试周期的结束。
3.3 温度效应
石英手表的快慢(走时精度)在很大程度上依赖于环境温度。因此，在室温环境或在手腕
上的工作温度条件下进行快慢(走时精度)测量时很重要的。尤其是比较测量应在相同的
8
温度条件下进行。
