AC/DC CURRENT CLAMPS E Series The E Series is designed to measure alternating and direct currents by means of Hall-effect technology. The currents measured extend from a few milliamperes to more than 100 A. The E25 model provides higher sensitivity for low current measurements. This clamp can be hooked up to multimeters, loggers, data processors, etc. The E27 can be connected directly to an oscilloscope. The long, narrow shape of these clamps makes them ideal for measurements in cable strands or confined spaces such as switchboard wiring, motor control units and the electrical circuits in automotive vehicles. Their low phase shift ensures excellent power measurement performance. These clamps are equipped with a voltage output (mV). Their ability to measure AC+DC signals is particularly useful for True RMS measurements.

AC/DC CURRENT CLAMP E25 model Current Output Description 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...
