reduced in order to allow the BENNING PV 3 to cool down. Do not leave the BENNING PV 3 attached to
a hazardous voltage for extended periods of time or while waiting for the BENNING PV 3 to cool down.
The BENNING PV 3 automatically tests connected PV modules, PV strings or PV fields. All measuring
results are displayed on the large LC display.

6. Environment conditions
- The BENNING PV 3 is intended for making measurements in dry environment.
- Maximum barometric elevation for making measurements: 2000 m,
- Over voltage category/ Siting category: IEC/ EN 61010-1 →1500 V for systems without a specified
measuring category,
- Pollution Class 2,
- Protection Class: IP 40 (DIN VDE 0470-1, IEC/ EN 60529) with the cover being open
IP 40 means: Protected against objects >1mm, (4 - first index). No protection against water, (0 - second
index).
IP 64 with the cover being closed
IP 64 means: Protection against access to dangerous parts and protection against solid impurities,
dustproof, (6 - first index). Splash proof, (4 - second index). Can also be used in case of precipitation.
- EMC: IEC/ EN 61326-1,
- Operating temperature and relative humidity: For operating temperature from 0 °C to 40 °C: non-
condensing
- Storage temperature: The BENNING PV 3 can be stored at any temperature in the range from - 25 °C
to + 65 °C (relative humidity from 0 to 90 %). The battery should be taken out of the instrument for
storage.
7. Electrical specifications
Note: The measuring precision is specified as the sum of
- a relative fraction of the measured value and
- a number of digits (counting steps of the least significant digit).
This specified measuring precision is valid for temperatures in the range from 18 °C to 30 °C and relative
humidity less than 80 %.

8. Measuring with the BENNING PV 3
8.1 Preparation for measuring
Operate and store the BENNING PV 3 only at the specified storage and operating temperatures conditions.
Do not permanently expose the device to sunlight.
- Strong sources of interference in the vicinity of the BENNING PV 3 can lead to unstable readings and
measuring errors.
