(Switch setting: V
For AC (alternating voltage) the measured value is obtained by mean value
rectification and displayed as r.m.s. value. The specified accuracy for AC
measurements is based on the sinusoidal waveform.

Accuracy:
Optical warning that a dangerous voltage is applied as from 30 V AC/ DC.
7.5­­ Measuring­­the­­battery­­capacity­­
(switch setting:
In accordance with EN 61557, the battery capacity is measured by connecting a
simulated load. Percentage indication from 0 - 100 % in 10 % steps.

8.1­­­­ P reparations­­for­­making­­measurements
Operate and store the BENNING IT 100 only at the specified storage and oper-
ating temperatures. Avoid continuous insolation.
-
C heck the nominal voltages and nominal current on the safety measuring cables.
The nominal voltage and current ratings of the safety measuring cables included
in the scope of delivery correspond to the ratings of the BENNING IT 100.
-
C heck the insulation of the safety measuring cables. Discard the safety
measuring cables immediately if the insulation is damaged.
-
C heck safety measuring lines for continuity. If the conductor in the safety
measuring line is interrupted, the safety measuring line must be quaran-
tined immediately.
-
B efore - at the rotary switch  - a different function is selected, the safety
measuring lines must be disconnected from the measuring point.
