In such cases the BENNING CM 9-2 must be switched off immediately, discon
-
nected from the measuring points and secured to prevent further utilisation.
9.2 Cleaning
Clean the casing externally with a clean dry cloth (exception: special cleaning
wipers). Avoid using solvents and/ or scouring agents for cleaning the instru
-
ment. It is important to make sure that the battery compartment and battery
contacts are not contaminated by leaking electrolyte. If electrolyte contamination
or white deposits are present in the region of the batteries or battery casing,
clean them too with a dry cloth.
9.3 Battery replacement
Before opening the BENNING CM 9-2, make sure that it is free of
voltage! Electrical danger!
The BENNING CM 9-2 is supplied by means of two 1.5 V batteries of type AA
(IEC LR06). Battery replacement is required as soon as all segments of the
battery symbol have disappeared and the battery symbol
on the display
6
is flashing.
Proceed as follows to replace the batteries:
- Remove the BENNING CM 9-2 from the measuring object and switch off the
BENNING CM 9-2.
- Lay the BENNING CM 9-2 face down and release the screws of the battery
compartment cover.
- Lift the battery compartment lid (in the housing recess area) from the bottom
section.
- Replace the exhausted batteries by two new ones of type AA (LR6). Make
sure that the new batteries are inserted with correct polarity!
- Place the battery compartment cover onto the bottom part and tighten the
screw.
