Chauvin Arnoux N93 Notice De Fonctionnement page 36

For the PAC93:
„ Set the switch to "1 mV/A"; the "ON" indicator lights.
„ Once the PAC93 is connected to the device, adjust the zero by turning the poten-
tiometer with no conductor in the jaws of the clamp.
„ At the end of the measurement, remember to switch off the PAC93.
For the E94:
„ Connect the clamp to the measuring instrument.
„ Make sure that the clamp is not on a conductor and that its jaws are correctly
closed.
„ Place the clamp in the position it will be in during the measurement.
„ Press the zero adjustment button.
„ The OL indicator lights for approximately three seconds to indicate that the zero
adjustment is in progress in the two ranges.
„ If the zero has been correctly adjusted, the OL indicator goes off. If it remains on,
the zero could not be adjusted.
For the clamps:
„ Press the trigger on the clamp to open the jaws.
„ Then clamp the cable that is to be measured. Where possible, the cable should
be centred in the jaws of the clamp.
„ Release the trigger.
For the MiniFlex models:
„ 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). Where possible, the cable should be centred
in the sensor.
