Press on the yellow opening device to open the flexible coil.
Open it and place it around the conductor carrying the current to be measured (only one conductor in
the sensor). Close the coil. You must hear the “click”.
In the case of an uninsulated conductor at a dangerous voltage, use individual protection
equipment.
To optimize measurement quality, centre the conductor in the coil.
Set the switch of the electronic unit to the range providing the best sensitivity and check that the red
OL
indicator is off (saturation of the electronics entailing a measurement error).
