<Measuring the current consumption for the circuit block alone>
•
Connect the tester to the input terminals (+) and (–) of the circuit block, and wait for 30 seconds to 2
minutes before starting the measurement, checking that a stable measurement is obtained.
Remarks: When the current consumption exceeds the standard value for the whole movement but is within
the standard value range for the circuit block alone, the watch is generating a driving pulse to
compensate for the heavy load that may be applied to the gear train, etc.
In this case, overhaul and clean the movement parts and then measure current consumption for
the whole movement again.

Output voltage for the solar cell unit
<Measuring the output voltage for the watch>
1) Set the dial to the solar cell unit.
2) Make sure that the rechargeable battery unit is not installed into the watch.
3) Pull out the crown to the second click and reset the circuit.
4) Connect the tester as shown in the illustration.
Pull out the crown to the
second click.
5) Place the watch at a distance of 5cm under a fluorescent light of 15 to 20 watts, exposing the dial side to
the light, and then measure the output voltage.

•
Use either of the following two methods to measure the output voltage for the solar cell unit.
1. Measurement of the output voltage for the watch
2. Measurement of the output voltage for the solar cell unit alone
Remarks: If the output voltage for the watch is less than the specified value, measure the output voltage for
the solar cell unit alone.
If the output voltage for the solar cell unit alone exceeds the specified value, check the solar cell
lead terminal for conductivity, etc.
Output voltage when the watch is placed at a distance of 5cm
under a fluorescent light of 15 to 20 watts: More than 2.3V.
