The EN series clamps use Hall-effect technology for the measurement of AC and DC currents from several milliamps to over 100 A. These clamps' narrow, elongated design makes them ideal for measurements in cable bundles or in other confined areas like circuit boards, motor controls or motor vehicle electrical circuits. Their low phase shifting also ensures excellent performance for power measurements.

These clamps have a voltage output (mv) and their ability to measure AC and DC signals is useful for true RMS measurements. Model E6N is the most sensitive for low current measurements. The E series clamps all make excellent work mates for multimeters, recorders and logging equipment, etc. Model E3N can even be connected directly to an oscilloscope
