Querying of momentary battery voltage via
menu function.
Power OFF function
The multimeter is switched off automatically:
– If battery voltage drops to below
approx. 1.8 V
– If none of the keys or the rotary switch
are activated for an adjustable duration
(10 to 59 min.) and the multimeter is not
in the continuous operation mode
Power pack socket If the power pack has been plugged into
the instrument, the installed batteries are
disconnected automatically.
Rechargeable batteries can only be
recharged externally.
