Battery capacity display with battery
symbol in 4 segments:
Querying of momentary battery voltage via
menu function.
Multimeter is switched off automatically:
– If battery voltage drops to below prox. 1.8 V
– If none of the keys or the rotary switch
If the
plugged into the instrument, the batteries
are disconnected automatically.
Rechargeable batteries can only be
recharged externally.
