The AEMC 502 clamp-on meters are built into a rugged mechanical case and are designed using quality polycarbonate materials. These meters offer a complete set of measurement ranges and are in compliance with international safety and quality standards to ensure a professional and reliable measuring tool.

These reliable meters are simple to operate and are auto-ranging — always providing the optimum measurement range and resolution. They both measure 400AAC, 600VAC, 600VDC, resistance, and continuity (with beeper).

The 502 model is a true RMS clamp-on that provides RMS measurements for today's non-linear electrical environments, such as variable speed drives or computers. The 502 model also includes a frequency function sensed from either current or voltage.

The tapered, hooked jaw design facilitates maneuvering in crowded wiring and breaker panels, making it easy to select conductors. The jaw opening accommodates a 500MCM cable. The large and easy-to-read 4000 count LCD features comprehensive user information symbols, such as low battery, polarity, overload and an analog bargraph for easy trend readings. Both models are equipped with a data hold function that freezes the measurement for later viewing.

AEMC 502 Clamp-On Meter Applications

  • Industrial, commercial, HVAC and residential troubleshooting
  • Power panel, junction box and battery bank monitoring
  • Electrical testing and troubleshooting on traditional and non-linear loads including adjustable speed drives and computers
