2.1. GETTING STARTED
Switch the clamp on by pushing the slide switch to the 1mV/A or the 10mV/A setting.
The 1mV/A setting corresponds to the 1400A range.
The 1mV/A setting corresponds to the 150A range.
The ON indicator lights green. If it blinks, there remain less than 4 hours of use. If it fails to light, you
must replace the battery (see § 4.2).
2.2. ZERO ADJUSTMENT
„ Switch the clamp on.
„ Make sure that the clamp is not on a conductor and that its jaws are correctly closed.
„ Connect the clamp to the measuring instrument. The phase is on the core of the BNC connector.
„ Press the zero adjustment button, DC Zero.
„ The OL indicator lights for approximately three seconds to indicate that the zero adjustment is in
progress.
„ If the zero has been correctly adjusted, the OL indicator goes off. If it remains on, the zero could
not be adjusted.
In this case, check that the clamp is not on a conductor and that its jaws are correctly closed, then
press the DC Zero button again.
Or switch the clamp off and back on; the last adjustment will then be used, even if it is not good.
2.3. MEASUREMENT
The zero must be adjusted before each measurement.
