Mesurement of the rate accuracy, the current consumption
and test of components of quartz watches.
For repair service, the watchmaker needs a test instrument
with a simple way to perform all electrical measurements
and tests on quartz watches. The instrument provides all
measuring and test facilities required in a professional
search for defects in quartz watches.
Operation is very easy, due to largely automated measurement
functions, the functional layout of operating elements
and the highly readable results and parameters on
an illuminated display.


Technical Data

Measurement possibilities
Rate accuracy, consumption, coil resistance, isolation and
battery voltage.

Signal sensor
Sensors of highest sensitivity and selectivity for acoustical,
magnetical and capacitive signals. Signal sensing over the
supply current. LED display for the signal intensity. The sensors
are also adequate for watches with closed straps.

Rate measurement
Measurement over the quartz frequency. Signal sensing
acoustical, capacitive or over the supply current. Measurement
over the motor pulses, magnetical or over the supply
current. Measurement over the LCD-operating frequency.
Rate measurement for mechanical watches.
Measuring times
Over the quartz frequency 1s. Over the motor pulses or
LCD-operating frequency: automatic determination for normal
or inhibition watches; from 2 up to 60 s. Manual selection
from 2 up to 480 s. 8 s for mechanical watches. Short
beep sound after the elapsed measuring time of 10 s or
more.
Display of the results
Selectable display mode in s/d or s/month. Measuring range
+/- 33.3 s/d resp. +/- 999 s/month. Resolution 0.01 s/d
resp. 1 s/month. Display of the measured motor pulse period.
Display of the remaining measuring time (count
down).

Module power supply
Supply voltage adjustable from 1.00 up to 1.55 V in steps
of 0.05 V and from 2.20 up to 3.00 V in steps of 0.10 V.
Current limit: 20 mA. Display of short circuits or interruptions.
Mobile probes for direct contacting on the working
surface of the instrument. Test leads with test probes. Built
in mirror for the observation of the hands during measurement.
Current measurement
Instant measurement of the IC consumption. Integrated
measurement of the average current consumption over a
motor pulse period.
Measuring times
Automatic: IC consumption 1 s. Total consumption over a
motor pulse period, min. 1 s, max. 60 s.
Manual: same as the selected measuring time for the rate
measurement.
Display of the results
3 digit display with automatic commutation of the range.
Measuring range: from 10 nA up to 20 mA. Resolution: 1
nA. Display of the IC consumption after 1 s. Display of the
total consumption after one motor pulse period, not before
5 s.
Battery test
Measuring range from 0 up to 5 V. Basic load: 2 MOhm .
When contacting the battery a load of 2 kOhm is automatically
applied for the duration of 10 ms. Switch on a load of
100 Ohm for the duration of 500 ms by means of the key.
Simultaneous display of the voltages for all activated loads.
Resistance measurement
Measuring range from 1 Ohm up to 15 MOhm. Automatic
commutation of the measuring range. Display of 3 digits.
Resolution: 1 Ohm.
Interface
RS232 for the connection of the Witschi thermo-printer, of
a PC or the Witschi GPS receiver. Print out of the numeric
results.
