MEASURING CURRENT CONSUMPTION

This model starts correct positioning of the second hand in the Hand Set mode immediately after AC.
When it is functioning, the value of consumption current would be a little higher as the internal circuit
operation would be different from the usual status.
Measure the current value at 5 seconds after AC is performed.
* Measure within one minute while light is blocked from the watch face.
* Supply voltage is 2.5V.
