    Œ  1.4. FUNCTIONS The E27 clamp can be used to measure current from 100mA to 100 A without opening the circuit in which it is flowing. It reads peak out the waveform and amplitude of the current being measured, in the form of a voltage. The pass band is from DC to 100kHz.

    2. USE 2.1. GETTING STARTED Switch the clamp on by pushing the slide switch to the 10mV/A or the 100mV/A setting. The 10mV/A setting corresponds to the 100A range. The 100mV/A setting corresponds to the 10A 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 §...

    If the OL indicator lights, it means that the current is too strong to be measured. If you are in the 100mV/A range, switch to the 10mV/A range. „ Apply the conversion factor corresponding to the setting of the switch. 100 mV/A 10 mV/A 500 mV...
