tery voltage falls below approx. 2.3 V.
Battery Saver Circuit
The instrument switches itself of automatically if the mea-
surement value remains unchanged for about 10 minutes,
and if none of the operating elements are activated during
this time. Automatic shut-off can be disabled.
This does not apply to the following functions: events,
counter, stopwatch, mains, power, transmission or menu
mode (send or menu mode) and continuous operation.
