Chauvin Arnoux E25 [P01120025] Current Clamps, 80 A DC / 60 A AC. The E25 clamp is designed to measure alternating and direct currents by means of Hall-effect technology. Its long, narrow shape makes it ideal for measurements in confined spaces where access is difficult. Via a cable terminated by 2 x Ø4 mm isolated male banana plugs, this clamp provides an AC+DC mV signal which is an image of the current measured in terms of waveform and amplitude. The E25 clamp is equipped with an automatic DC Zero system and a deactivatable Auto Power Off (APO) function. It can be powered by battery or by a standard mains power pack via a Micro USB connector and offers 2 different sensitivities. The E25 clamp, equipped with a cable terminated by 2 x Ø4 mm insulated male banana plugs, is the ideal complement for any multimeter or other measuring instrument. The E27 clamp is an insulated current sensor whose wide bandwidth is useful for measuring and viewing complex AC+DC signals on an oscilloscope.
