Always place the current sensor around only one
conductor, since the currents may otherwise cancel each
other out and wrong measured values may be displayed.
Never reach beyond the grip area (5) (marked with two
arrows in the sketch).
If current is flowing in the conductor, the current can be
read at the meter.
The following alternate voltages are output proportionally
to the measured current:
30 A range
100 mV/A
300 A range
10 mV/A
3000 A range
1 mV/A
For a single- and three-phase connection able with a firmly installed mains plug, use the optional current
measuring adapters if required. They facilitate measurement at firmly connected mains cables.
When reaching around the conductor, ensure that the conductor is at the centre
of the Flex current sensor. A deviating position increases the measuring error
(measuring deviation).
The following table shows the error tolerances to be added up and the corres-
ponding distances from the centre. The centre is marked with a “+” in the sketch.
