1.2 Power management
1.2.1 230 V / 110 V operation
The instrument works on 110 V and 230 V mains. 110 V and 230 V appliances can be fully
tested.
In UK and Aus/Nz models only 110 V mains voltage will be applied to the mains test socket if
the 110 V test adapter (A 1474) is connected to the instrument.
1.2.2 Battery and charging, auto power off
The instrument has an in-built rechargeable battery pack. The battery is charged whenever the
instrument is connected to the mains. When the instrument is disconnected from mains, the
battery provides power to the instrument to stay energized for 1 minute. This is indicated by the
battery symbol in the upper right corner of the LCD. Operation with the instrument is not
possible except the mains was disconnected during the RCD test. As long as the instrument is
energized it will be ready to use immediately after connected to mains voltage again. This
enables faster testing of appliances.
If the instrument is not reconnected to mains within 1 minute it will completely switch off. When
connected to mains again, a normal power up procedure will be taken.
Figure 1.1: Indication of battery status
Notes:
A flat or faulty battery will result in an immediate power off after the instrument is
disconnected from the mains.
Charging time of the battery is about 14 h.
1.2.3 Power Off, Restart
