The
Wh/TIME
and the time setting dial on the 3181-01
front panel are used to set the integration time in the
range 1 to 99 minutes or 1 to 99 h. Once the desired time
is set, pressing the
START
switch resets the internal
circuits and integration begins. When the set time is
reached, the counter output is put on hold. If the
integrator is started with the timer set to "00", it
performs continuous integration.
The
HOLD/RUN
switch
on the front panel is used to stop the counter and start
again. Below the V-F converter there is a backup battery
which maintains continuous operation in the event of a
power failure, so there is no danger of loosing watthour
values measured up to the power failure.
