Mains operation and
charging the batteries
You can operate the measuring instrument either with the built-in re-
chargeable batteries or with the plug-in power supply. The plug-in pow-
er supply supplies the measuring instrument with low voltage (9 V DC).
At the same time, the rechargeable batteries are charged. The batter-
ies are charged even when the instrument is switched off.
Charging time of the
batteries
approx. 36 hours. The LoBat display indicator appears when the batter-
ies are nearly empty and have to be charged as soon as possible.
Caution
The line voltage at the operating site must lie within the input
voltage range of the original plug-in power supply (see chapter

ate the instrument for a longer period of time you should charge the bat-
teries every six months.
