3.2 Power supply
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
7 T
ECHNICAL DATA
).
Caution
Use original plug-in power supplies only (see
chapter 7 T
ECHNICAL DATA
).
Note
The batteries should not be completely discharged. If you do not oper-
ate the instrument for a longer period of time you should charge the bat-
teries every six months.
Automatic switchoff The instrument has an automatic switchoff function in order to save the
batteries (see section 4.3.3).
Display illumination

switches off the display illumination if no key has been pressed for
15 seconds. The illumination is switched on with the next keystroke
again. The display illumination can be switched off completely.
