6. Ambient conditions
- The BENNING SUN 2 is intended for measurements under dry ambient conditions,
- Maximum barometric height for measurements: 0 m to max. 2000 m
- Contamination level: 2
- Protection category: IP 40 (DIN VDE 0470-1, IEC/ EN 60529)
4 – first index: protection against access to dangerous parts and protection against solid
impurities of a diameter > 1.0 mm
0 – second index: No protection against water
- EMC: IEC/ EN 61326,
- Operating temperature and relative air humidity:
For operating temperatures from 0 °C to 50 °C: relative air humidity lower than 80 %, non-
condensing
- Storage temperature: The BENNING SUN 2 can be stored at temperatures between - 20 °C
and + 60 °C (air humidity 0 to 80 %). During storage, the batteries must be removed.
7. Measuring ranges
Note: The measuring accuracy is specified as the sum of:
- a relative part of the measured value and
- a number of digits (i.e. counting steps of the last digit).
This measuring accuracy applies to temperatures from 0 °C to 50 °C and a relative air humidity
lower than 80 %.

8. Measuring with the BENNING SUN 2
8.1 Preparing the measurement
Operate and store the BENNING SUN 2 at the specified storage and operating temperatures
only!
- Strong sources of interference in the vicinity of the BENNING SUN 2 might involve unstable
readings and measuring errors.
Before commissioning, always check the device as well as all connecting
cables for damages.
