Notes:
*Light may increase the current consumption, resulting in an inaccurate measurement. If the current consumption exceeds the standard value, protect the movement from light with a black cloth or the like after following step “3” above, and make a measurement again.
*When the current consumption for the whole movement exceeds the standard value while the current consumption for the circuit block alone is within the standard value range, a driving pulse may be generated to compensate for the heavy load applied on the gear train, etc. In that case, overhaul and clean the movement parts, and then, measure the current consumption for the whole movement again.
How to measure the current consumption for the circuit block alone
1. Connect the tester to the circuit block as shown in the illustration.
“A” portion
2.With the tester connected to the circuit block,
3.Checking that a stable measurement is obtained, read the current consumption.
Notes:
*The current consumption measurement for the circuit block alone is particularly susceptible to light, and a value higher than the actual measurement may be obtained if the circuit block is exposed to light. Protect the circuit from light with a black cloth or the like after following step “2” above, and then, measure the current consumption.
*If the current consumption for the circuit block alone exceeds the standard value, the duration of the charge will be shorter than specified. In that case, replace the circuit block with a new one.
●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
*If a
measure the voltage again, checking that a stable measurement is obtained.
