CONNECTIONS AND BUTTONS + Positive connection for module supply and battery test(the two red sockets and the battery support are connected together).
< >Negative connection for the module supply and battery test(the two black sockets are connected together).InstallationAINS 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.
< >PRINTER CONNECTIONSWITCHING THE DISPLAY OF THE RATE FROM SEC/DAY TO SEC/MONTHTEST MODE SELECTION,are automatically selected when the instrument is switched on.
Detailed information concerning the various test modes is given in the following sections.
< >TEST PARAMETER SELECTION AND SETTINGRATE MEASUREMENT-GENERAL INFORMATIONPRINCIPLE OF OPERATIONMEASURING PROCEDURETEMPERATURE EFFECTSTESTING OF WATCHES WITH DIGITAL TRIMMING(INHIBITION)RATE MEASUREMENT MODES32 kHz QUARTZ TEST MODE 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.
< >LCD TEST MODESTEPPING MOTOR TEST MODE (stepp. motor) 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.
< >MECHANICAL TEST MODE (mechanical)TUNING FORK TESTMODE (tuning fork)SPECIAL PROGRAMS FOR PROGRAMMABLE ICs (special program)Set the voltage to 1.55V in the PARAMETER field with supply voltage.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:CURRENT CONSUMPTION MEASUREMENTENERAL 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.
< >CONTACT TO THE WATCHμA 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.
< >SUPPLY VOLTAGEMEASURING PERIODTHEμA MEASURING RANGE (consumption μA )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.
< >THE mA MEASURING RANGE (consumption mA)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.
< >STARTING VOLTAGEBATTERY TESTGENERAL INFORMATIONBATTERY LOADμA. 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 button. This load corresponds approximately to the peak load during a motor pulse.
A load of 100Ω may be added by pressing the high drain button. 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 button should not be pressed for longer than necessary otherwise the battery will be quickly drained.

< >RESISTANCE MEASUREMENTGENERAL INFORMATIONΩ 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.
< >COIL RESISTANCE AND COIL INSULATIONΩ 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.
< >CONTINUITY AND INSULATION TESTPULSE GENERATORAPPLICATION\PARAMETER SETTINGALARM TESTTROUBLE SHOOTING FOR QUARTZ WATCHESSYSTEMATIC TROUBLE SHOOTING• 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.
< > BATTERY IC DEFECTSμA 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).
< >MECHANICAL DEFECTS• 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.
< >LCD-DISPLAYS• 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.
