5. Specific Data of the Analyser

5.1 Power Supply and Replacing the Battery Pack

Power-line or Battery Mode

Your Power Analyser can be operated with the provided charging adapter
or with the built in battery.
If you operate your device with the charging adapter, the battery is charged
automatically. On the LC display the symbol for the operating mode is
displayed accordingly (see Chapter 2.2).
If the battery is completely discharged, it takes about 4 hours to charge it
completely. It is impossible to overcharge the battery as the analyser has
an automatic load regulation.
When "LO-BAT“ is indicated, replace the batteries or recharge the
accumulator.

Replacing the accumulator pack

If the accumulator capacity is noticeably low (see technical specification),
then the accumulator pack has to be replaced. Please consider the
following steps, which are described in the following figures:

1. Turn off the device

2. Disconnect all measuring leads

3. Open the battery compartment (two cross-notched

screws)

4. Unplug and replace the battery pack. Close the

battery compartment again.
