4.4 Voltage supply
The BAT segment indicates that the battery must be replaced soon. At this point correct
measurements can be performed for approx. 1 hour.
A 9 V battery is used as voltage supply of the instrument.
Replacing batteries
For battery replacement switch off the instrument and open the battery compartment
attached on the rear side. After that remove the battery and disconnect the connection
cable. Then insert the new batteries into the battery compartment.
Switch in the battery compartment on the rear side allows to specify whether the
instrument is operated with a battery or a rechargeable battery.
With the setting Batt the charging current supplied via USB interface is not directed to
the battery, which allows to avoid its damage.
With the setting Accu the rechargeable battery is only energized via USB interface. The
accu will be provided with charge current, but this is not enough the recharge the accu
completely.
If the instrument is not used for a long time, remove the battery.
When closing the battery compartment make sure that the battery
connection wires are not jammed or damaged.
