Error code
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 ensure that all the test leads have been
c
disconnected from the BENNING PV 1-1. Danger of electric shock!
The BENNING PV 1-1 is supplied by six 1.5 V batteries/ type AA (IEC LR6).
A battery change (see Figure 9) is required, if the battery symbol P appears in the display unit 1 .
Proceed as follows to replace the batteries:
- Switch the BENNING PV 1-1 off.
- Put the BENNING PV 1-1 face down and unscrew the screw of the battery compartment
cover.
- Lift off the battery compartment cover (in the area of the housing slots) from the bottom part
of the battery compartment.
