5. General information

The BENNING IT 105 is intended for electrical safety tests in compliance with DIN VDE 0100-600
(IEC 60364-6) and DIN VDE 0105-100 (EN 50110).
- Appliance dimensions: (length x width x height) = 235 x 132 x 92 mm
- Appliance weight: 1370 g incl. batteries

6. Ambient conditions

- The BENNING IT 105 is intended for making measurements in dry environment,
- Maximum barometric elevation for making measurements: 2000 m,
- Overvoltage category/ setting category: IEC 61010-1 → 300 V category III,
- Contamination class: 2,
- Protection class: IP 40 (DIN VDE 0470-1 IEC/ EN 60529)
IP 40 means: Protection against access to dangerous parts and protection against solid impurities of
a diameter > 1 mm, (4 - first index). No protection against water, (0 - second index).
- EMC: EN 61326-1
- Ambient temperature and relative humidity:
For ambient temperatures from 0 °C to 40 °C: non-condensing
- Storage temperature: The BENNING IT 105 can be stored at any temperature within the range of
- 25 °C to + 65 °C (relative humidity from 0 to 90 %). The batteries should be removed from the instru-
ment for storage.

7. Electrical specifications

Note: The measuring accuracy 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).
The specified measuring accuracy is valid for temperatures within the range of 18 °C to 28 °C and for a
relative humidity lower than 80 %.
