Securing The Instrument; Battery Replacement - Benning PV 1-1 Bedienungsanleitung

9.2 Securing the instrument

Under certain circumstances safe operation of the BENNING PV 1-1 is no longer ensured, for
example in the case of:
- Visible damage of the casing.
- Incorrect measurement results.
- Recognisable consequences of prolonged storage under improper conditions.
- Recognisable consequences of extraordinary transportation stress.
In such cases the BENNING PV 1-1 must be switched off immediately, disconnected from the
measuring points and secured to prevent further utilisation.
9.3 Cleaning
Clean the casing externally 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 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.

9.4 Battery replacement

Before opening the BENNING PV 1-1, make quite sure that it is voltage free!
c
Electrical danger!
The BENNING PV 1-1 is supplied by six 1.5 V batteries/ type AA (IEC LR6).
