ensured, for example in the case of:
- Visible damage of the casing.
- Incorrect measurement results.
- Recognizable consequences of prolonged storage under improper condi-
tions.
- Recognizable consequences of extraordinary transportation stress.
In such cases the BENNING IT 101 must be switched off immediately, discon-
nected from the measuring points and secured to prevent further utilization.
9.2 Cleaning
Clean the exterior of the housing with a clean dry cloth (exception: special
cleaning wipers). Avoid using solvents and/or scouring agents for cleaning the
instrument. It is important to make sure that the battery compartment and bat-
tery contacts are not contaminated by leaking electrolyte.
If electrolyte contamination or white deposits occur in the area of the batteries
or battery compartment, clean them too with a dry cloth.
