1 Measurement of
secondary
battery voltage
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.)
2 Comfirmation of * Refer to Technical Manual, Basic Course: II-1-b.
output signal
<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.
