AEMC Clamp-on Meter Model 403 The True RMS Clamp-On Meter Model 403 is safety rated at 1000V CAT IV. It measures voltage, current, resistance, frequency, True InRush®, temperature, and continuity. It can also perform diode checks. Adapter mode allows external sensor inputs to be displayed. Delta relative function allows new measurements to be compared to a reference value. This rugged meter can operate in demanding work environments, and its IP54 rating allows it to withstand both dust and water spray.
