AC conversion:

The AC conversion is capacity-coupled (AC-coupled), TRUE RMS behaviour,

calibrated against a sinusoidal signal. In case of non-sinusoidal curves the

display value becomes less precise. Thus an additional error results for the

following crest factors:

Crest factor from 1.4 to 2.0 additional errors + 1.0 %

Crest factor from 2.0 to 2.5 additional errors + 2.5 %

Crest factor from 2.5 to 3.0 additional errors + 4.0 %

7.2 Insulating resistance measuring ranges

(switch setting MΩ, 50 V/ 100 V/ 250 V/ 500 V/ 1000 V)

Measuring range Resolution Accuracy

4 MΩ 0.001 MΩ ± (1.5 % of the measured value + 5 digits)

40 MΩ 0.01 MΩ ± (1.5 % of the measured value + 5 digits)

400 MΩ 0.1 MΩ ± (3.0 % of the measured value + 5 digits)

4000 MΩ 1 MΩ ± (3.0 % of the measured value + 5 digits)

4.1 GΩ ... 20 GΩ 0.1 GΩ ± (10 % of the measured value + 3 digits)

Minimum / maximum resistance depending on the testing voltage:

Testing voltage Min. resistance (at 1 mA) Max. resistance

50 V 50 kΩ 50 MΩ

100 V 100 kΩ 100 MΩ

250 V 250 kΩ 250 MΩ

500 V 500 kΩ 500 MΩ

1000 V 1 MΩ 20 GΩ

Accuracy of testing voltage: - 0 %, + 20 %

Short-circuit current: 1 mA (nominal)

Automatic discharge function: discharging time < 1 sec. for C < 1 µF

Max. capacitive load: operational for loads of up to 1 µF

Detection of a connected electric circuit: if > 30 V AC/ DC, then 

8. Measuring with the BENNING IT 101

8.1 Preparations for measuring

Operate and store the BENNING IT 101 only at the specified storage and oper-

ating temperatures. Avoid continuous insulation.

- Check the nominal voltages and nominal current on the safety measuring

leads. The nominal voltage and current ratings of the safety measuring

leads included in the scope of delivery correspond to the ratings of the

BENNING IT 101.

- Check the insulation of the safety measuring leads. Dispose of the safety

measuring leads immediately if the insulation is damaged.

- Check the safety measuring leads for continuity. If the conductor in the

safety measuring lead is interrupted, the safety measuring leads must be

dispose of immediately.

- Before a different function is selected by means of the rotary switch J, the

safety measuring leads must be disconnected from the measuring point.

- Strong sources of interference in the vicinity of the BENNING IT 101 might

lead to unstable readings and measuring errors.
