Power OFF function
The multimeter is switched off automatically:
– when battery voltage
drops to below approx. 3.6 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 operating mode
Rechargeable battery packs can only be recharged externally.
