Measurement of
secondary
battery voltage
Comfirmation of
output signal
* Refer to Technical Manual, Basic Course:
II-1-b.
<Tester range: DC. 0.3V>
<The tester lead pins have no polarity>
• In the 1-second interval movement mode, the tester
pointer should moves to the right and left every 1 sec-
ond.
• In the 2-second interval movement or hitch movement
mode, the test pointer moves in only one direction every
2 seconds.
<Tester range: DC. 3V>
Reference:
• 1.1V ~ 1.3V: Two-second interval movement mode
1.3V ~ 1.8V: One-second interval movement mode
These voltages may vary slightly from watch to watch.
• A quick-start is activated by the small-capacity tantalum
capacitor which has been incorporated in the circuit, in
addition to the primay secondary battery. After the watch
is illuminated (right after it begins running), the sec-
ondary battery voltage will display an extremely low
value because the secondary battery has not been fully
charged.
Note:
When measuring the voltage, be careful not to place
the - tester pin on the secondary battery strap (a
short circuit will occur.)
• Tester pointer swings.
→ Normal.
• Tester pointer does not
swing.
→ Check connections.
h
• Connections are normal.
→ Replace the electronic
circuit.
