1.9 Batteries and fuses
Batteries
Warning:
Disconnect all test cables / accessories from the tester and from the installation and
switch the tester off before opening the cover of the battery / fuse compartment.
Dangerous voltages might occur inside the tester!
Use alkaline batteries or rechargeable NiMh batteries (storage batteries) of the size AA
only! Do not recharge alkaline batteries!
Please make sure that the batteries / storage batteries are inserted with correct polarity,
because otherwise the tester cannot be operated and the batteries / storage batteries will
discharge.
If the tester will not be used for a longer period of time, remove all batteries / storage
batteries from the battery compartment in order to protect the tester against leakage of
the batteries / storage batteries.
The rechargeable NiMh batteries (storage batteries) will be recharged automatically as soon as the
charger is connected to the charging socket. An integrated protective circuit controls the charging
process.

Note:
Before the first use! Insert the storage batteries into the battery compartment and charge the
storage batteries for at least 16 hours.
