AEMC 503 (2117.22) AC/DC Clamp-On Meter: 400A, 600V (AC/DC)

DISCONTINUED ITEM-Recommended Replacement: AEMC 505 (2139.82) AC/DC Clamp-On Meter

The Clamp-On Meter Model 503 is an all-purpose professional clamp-on. Full ranges, quality materials, a strong mechanical case design, and compliance with quality standards and international safety ensure a reliable and professional tool. The Model 503 is auto-ranging, and provides the user with AC Volts, DC Volts, AC Amperes, DC Amperes, resistance, and continuity.

The complete and large 4000-count LCD features comprehensive user interface symbols like a low battery indicator. It’s included with a Data Hold function, that freezes the measurement. The Model 503 is compact for one-handed operation (that’s comfortable), and the hooked jaw design is simple to maneuver in breaker panels and crowded wiring. The jaw opening for the Model 503 is 1.1" (28mm).
