Function Check; Battery Clamp - Seiko 5M54A Technical Manual

TECHNICAL GUIDE
l Value checking
• Coil resistance (coil blocks)
Check the resistance of each COIL BLOCK if they are within the range in the following table.

l Function check
• Checking the automatic generating system
1. Apply the probes of the tester as shown in
the illustration, and measure the voltage of
the RECHARGEABLE BATTERy. The obtained
voltage is called the "initial voltage".
Notes:
* When applying the minus probe of the
tester to the RECHARGEABLE BATTERy,
take care not to short-circuit the lead
terminal (-) and the RECHARGEABLE

BATTERy CLAMP.

* If a short-circuit has occurred, leave
the watch untouched for more than 10
minutes, and measure the voltage again,
checking that a stable measurement is
obtained.
2. Close the case back tentatively, and swing the
watch from side to side 200 times at a rate
of 2 to 3 swings a second, making an arc of
approximately 20 cm.
