TECHNICAL GUIDE

Cal. 5M62A, 5M63A

1. Connect the tester to the circuit block as shown in the illustration.

How to measure the current consumption for the circuit block alone

“A” portion

2. With the tester connected to the circuit block, short-circuit “A” portion in the illustration and the input

terminal (–) with conductive tweezers or the like for more than 3 seconds. The IC will be switched from

the quick start to the normal hand movement mode.

3. Checking that a stable measurement is obtained, read the current consumption.

If the measurement value remains high or unstable, repeat step “2” above.

Note: 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.

● 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.
