VALUE CHECKING
II.
● Coil block resistance
2.0 ∼ 2.5 kΩ
● Current consumption
For the whole of the movement：less than 1.30μA
For the circuit block alone：
Remarks:
When the current consumption exceeds the standard value for the whole of the movement but is less
than the standard value for the circuit block alone, overhaul and clean the movement parts and then
measure current consumption for the whole of the movement again. The driving pulse generated to
compensate a heavy load that may apply on the gear train, etc. is considered to cause excessive current
consumption for the whole of the movement.
less than 0.20μA
