During mains operation, one of the following symbols is displayed:
Note
Charge the batteries completely prior to putting the meter into operation
for the first time. The charging process takes approx. 10 hours. The
symbol is displayed if the batteries are nearly discharged.
3.3.3 Switching on the meter
Note
The meter has an energy saving feature to avoid unnecessary power
consumption during battery operation.
The energy saving feature switches off the meter during battery opera-
tion if no key is pressed during the adjusted interval. (How to set the
switch-off interval, see section 4.4).
The switch-off interval of the energy saving feature is not active when
the meter is supplied with power via the power pack or the USB-B
cable.
1 Connect the plug of the power pack to the socket for the power
pack on the Multi 3430.
2 Connect the original power pack to an easily accessible power
outlet.
