Check the battery voltage outside of the
movement.
Motor functioning
Place the battery with the stem in
position 1 only and make sure that
the counter motors perform a slow,
even run.
Measurement with controlled battery.
If the battery is depleted, the movement
will not move.
Move the stem into position 2 and
make sure that the counter motors
perform a fast, even turn.
