7. Electrical specifications
Note: The measuring precision is specied as the sum of
- a relative fraction of the measured value and
- a number of digits (counting steps of the least signicant digit).
This specied measuring precision is valid for temperatures in the range from 18 °C to 30 °C and
relative humidity less than 80 %.

8. Making measurements with the BENNING PV 1-1
8.1 Preparations for making measurements
Operate and store the BENNING PV 1-1 only at the specied storage and operating tempera-
tures conditions. Do not permanently expose the device to sunlight.
- Check rated voltage and rated current details specified on the safety measuring leads.
- Strong sources of interference in the vicinity of the BENNING PV 1-1 can lead to unstable
readings and measuring errors.
m
Before starting the BENNING PV 1-1, always check the device, the leads and
the test object for damages.
8.1.1 Switching the BENNING PV 1-1 ON/ OFF
- Press and hold the keys
2
and
3
for approx. 2 seconds to switch the BENNING PV 1-1 on.
