15 precautions for use this device is compliant with safety standard iec 61010‑2‑032, for voltages up to 600v in category iii. Failure to observe the safety instructions may result in electric shock, fire, explosion, or destruction of the instrument and of the installations. the operator and/or th...
16 1. Presentation the e3n clamp is a current probe based on a hall effect cell and intended for use with an oscilloscope; it can be used to measure direct or alternating current without making any changes to the installation (without opening the circuit). It can measure currents from 50ma to 100 ap...
17 3. Procedure to make a current measurement, switch the clamp on by selecting the 100mv/a range. Check that the on battery indicator (green) is lit and that the ol indicator is off. connect the clamp to the oscilloscope. With the clamp closed and not on a conductor, select the highest sensitiv...
