hours
Battery test Battery capacity display with battery
symbol in 4 segments: .
Querying of momentary battery voltage via
menu function.
Power OFF 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
are activated for an adjustable duration
of 10 to 59 minutes, and the multimeter
is not in the continuous operation mode
Power pack socket (METRAHIT⏐X-
TRA⏐OUTDOOR only)
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.
