Do not use cleaning agents which contain carbon, petrol, alcohol or similar substances for cleaning
purposes. These could corrode the surface of the measuring instrument. Furthermore, the fumes are
hazardous to your health and explosive. Moreover, you should not use sharp-edged tools, screw-
drivers or metal brushes or similar for cleaning.
For cleaning the device or the display and the measuring lines, use a clean, fuzz-free, antistatic slight-
ly damp cloth. Leave the device to dry completely prior to using it for the next measuring operation.
Inserting/changing the batteries
The multimeter requires two AAA batteries for operation. You need to insert new, charged batteries pri-
or to initial operation or when the battery change symbol appears on the display.
The line allocator requires a 9V compound battery just like the “remote” unit. You need to insert a new
battery once the display shows “LO BAT”.
To insert/replace the batteries in the DMM, proceed as follows:
- Disconnect the measuring device from all measuring circuits
and turn it off.
- Remove the protective rubber frame (12) from the device.
- Undo the screws on the battery compartment cover (11) and
remove the cover.
- Place new batteries into the battery compartment observing
the correct polarity.
- Now close the housing carefully again.
To insert/replace the batteries in the remote unit, proceed as
follows:
- Disconnect all measuring cables from the device and switch
it off.
- Undo the screw of the battery compartment cover (15) and
remove the cover.
- Place a new battery into the battery compartment, observing
the correct polarity.
- Now close the housing carefully again.
Never operate the measurement device when it is open.
!RISK OF FATAL INJURY!
Do not leave flat batteries in the device. Even batteries protected against leaking
can corrode and thus release chemicals which may be detrimental to your health or
destroy the battery compartment.
Do not leave batteries lying around carelessly. They might be swallowed by chil-
dren or pets. If swallowed, contact a physician immediately!
