Voltage of battery
1.50 - 1.55 V
Battery test
Battery must be removed from movement
Consumption (M1) of movem. (Pos. I)
1.20 - 3.1 µA
Supply power from measurement equipment (1,55 V)
Consumption (M1) of movem. (Pos. III)
0.1 - 0.3 µA
Supply power from measurement equipment (1,55 V)
Lowest voltage for movement (M1)
less than 1.3V
Lower limit for operation of movement
Adjust voltage on the measuring eqipement to 1.55 V. The slowly reduce the
tension untill the movement stops
Accuracy (seconds / month)
-10/+20 s/M
Check for a time of minimal 60 seconds
Resistance of the coil: motor 1 (movem.)
1.5 - 1.7 kOhm
Ref. 3621.053.RK
The resistance of the coil can be measured on the electronics.
