The AEMC Model 203 clamp on meter is a True RMS instrument that is safety rated at 600V CAT IV. It measures AC + DC volts and amps, frequency, continuity, resistance and can also perform diode checks. An adapter mode allows external sensor inputs to be displayed. The Model 203 includes temperature measurement and is supplied with a K thermocouple probe. A Delta relative function allows new measurements to be compared to a reference value and a MIN/MAX function keeps track of these high and low values.

The AEMC Model 203 is rugged enough for the most demanding work environments and its IP54 rating allows it to withstand both dust and water spray. Function selection can easily be performed with one hand, even with a glove on.

Applications for the AEMC Model 203 Clamp On Meter include:

  • Electrical maintenance and power distribution
  • Safety lighting system maintenance
  • Automotive test troubleshooting
  • AC or DC motor testing
  • Power plant troubleshooting
  • Commercial, industrial residential & HVAC troubleshooting
  • Power panel, junction box and battery bank measuring
  • Electrical testing and troubleshooting on non-linear loads, such as adjustable speed drives and computers
