5.2.4 current sensors

5.2.4.1 Precautions for use

Refer to the safety sheet or user manual that was supplied with your current sensors for more information.

5.2.4.2 use and characteristics

Current clamps and flexible current sensors are used to measure the current flowing in a cable without opening the circuit.
They also insulate the user from dangerous voltages in the circuit.
■
The choice of current sensor to be used depends on the current to be measured and the diameter of the cables.
■
When installing current sensors, face the arrow on the probe or the sensor in the direction of the load.
5.2.4.3 Miniflex
®
The Flexible Current Sensor MiniFlex
the circuit. It also serves to isolate the user from hazardous voltages in the circuit. This sensor can only be used as an
accessory of an instrument. Before connecting it, if you have several sensors, you can mark each of them using one of
the color-coded ID markers supplied with the instrument to identify the phase. Then connect the sensor to the instrument.
■
Press the yellow opening device to open the Flexible coil. Then, place it around the conductor through which the
current to be measured flows (only one conductor in the sensor).
■
Close the coil. In order to optimize measurement quality, it is best to center the conductor in the coil and make
the shape of the coil as circular as possible.
■
To disconnect the coil, open it and withdraw it from the conductor. Then, disconnect the sensor from the
instrument.

NOTE: Currents < 0.05% of the nominal range (100, 400, 2000 or 10000A) will be displayed as zero.
The nominal ranges are reduced to 50/200/1000/5000A

5.2.4.4 other current sensors

The measurement ranges are those of the sensors. In some cases, they may differ from the ranges that can be measured
by the PEL. For use, see the manual distributed with the current sensor
NOTE: Power calculations will be zeroed when the current is zeroed.
