4.5 Voltage supply
The battery life is approx. 20 hours for continuous operation.
The
BAT
segment indicates that the battery must be replaced soon. From this point,
correct measurements can be performed for approx. 1 hour. A 9 V battery is used as
voltage supply of the instrument. For information on the battery see chapter 4.6 “Battery
replacement”.
4.6 Battery replacement
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, so that this does not damage it.
■
With the setting
Accu
, the rechargeable battery is charged only via the USB interface.
While the rechargeable battery is supplied with a charging current, this is not, however,
enough to charge the battery fully.
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.
