Gossen MetraWatt METRAHIT ENERGY TRMS System Multimeter Operating Instructions Manual page 83

Power Supply
Battery 2 each 1.5 V AA batteries,
alkaline manganese per IEC LR6
(2 each 1.2 V NiMH rechargeable batteries
also possible)
Service life With alkaline manganese: approx. 120 hrs.
Battery Indicator Battery capacity display with battery
symbol in 4 segments:
Querying of momentary battery voltage via
menu function.
Power OFF function The multimeter is switched off
automatically:
– When battery voltage drops below
approx. 1.8 V
– If none of the keys or the rotary switch
are activated for an adjustable duration
of 10 to 59 min. and the multimeter is
not in the continuous operation mode
(assuming the instrument is not set to
power measurement or mains analysis)
Power pack socket If the NA X-TRA power pack has been
plugged into the instrument, the batteries
are disconnected automatically.
Rechargeable batteries can only be
recharged externally. Power pack voltage:
