The Clamp-On Meter Model 503 is a general-purpose professional clamp-on. This compact meter is built with a rugged case design, quality materials, full ranges, and compliance to international safety and quality standards to ensure a professional and reliable measuring tool. The Model 503 is auto-ranging and provides the user with AC Volts, DC Volts, AC Amperes, DC Amperes, resistance, and continuity.
The large and complete 4000-count LCD features comprehensive user interface symbols such as a low battery indicator. It is equipped with a Data Hold function, which freezes the measurement. The Model 503 is compact for comfortable one-handed operation, and the hooked jaw design is easy to maneuver in crowded wiring and breaker panels. The jaw opening for the Model 503 is 1.1" (28mm).
The AEMC Models 500, 501, 502, and 503 are compact, professional clamp-on meters that measure up to the toughest standards. They 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 all measure 400AAC, 600VAC, 600VDC, Resistance, and Continuity (with beeper). Models 501 and 502 also add a Frequency function sensed from either current or voltage. Models 501 and 503 are average sensing for traditional load environments. The Model 502 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 Model 503 is a Hall Effect clamp-on that provides both DC and AC current measurements to 400A.
Models 500, 501, 502, and 503 are compact for comfortable one-handed operation. 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 the low battery, polarity, overload, and an analog bar graph for easy trend readings. All models are equipped with a Data Hold function that freezes the measurement for later viewing.
They include a padded carrying pouch with leads, batteries, and user manual - ready to go!
