3.4 Mains Connection
Ð Connect the test instrument to 230 V or 120 V mains power
(depending on the country-specific design) with the included
mains connector cable.
Attention!
!
If a connection via earthing contact outlet is not possible,
disconnect the mains from all sources of voltage before
connecting the cables of the coupling socket via pick-up
clips with the mains connections, as shown in the draw-
ing.
If a battery pack has not been installed, the mains connection
symbol appears after the test instrument has been
switched on.
If a battery pack has been installed (feature C1), it is automatically
recharged. The battery symbol appears at the display, and
the blinking bars shown in this symbol indicate the remaining
capacity which still needs to be charged. The device need not be
disconnected from mains power after the batteries have been fully
charged (overcharge protection).
3.4.1 DC Operation (automotive charging adapter in preparation)
If a battery pack (feature C1) has been installed and the device is
not connected to the mains, the battery symbol appears at
the display when the device is switched on, and the number of
dark bars displayed in the symbol indicates the battery charge
level.
After installing the battery pack, the device is automatically sup-
plied with power from the batteries.
The automotive charging adapter (feature J1) can be used to
operate the device and charge the batteries.
