6.2.4 Current Sensors
6.2.4.1 Precautions For Use
NOTE: Refer to the safety data sheet provided or the downloadable
user manual.
Current clamps and flexible current sensors are used to measure the current
flowing in a cable without opening the circuit.
They also isolate the user from dangerous voltages present in the circuit.
The choice of the current sensor to use depends on the current to be measured
and the diameter of the cables. When installing current sensors, point the arrow
on the sensor towards the load.
When a current sensor is not connected, the device displays
