The Extech EX503 is an industrial quality averaging multimeter featuring 1000V input protection over all ranges.
The EX503 was designed to handle the rigors of field testing in adverse conditions including drop-tests from 6
feet as well as double molded housing for waterproof protection to IP67 standards. The EX503 also includes a
CAT-IV-600V safety rating for industrial applications.
The Extech EX503 is a versatile instrument capable of accurately measuring AC/DC voltage, AC/DC current, resistance,
capacitance and frequency. The basic accuracy of the meter is ±0.5%. Results are displayed on a large, 4000-count
LCD.
Additional features of the Extech EX503 include: diode and continuity tests, Data Hold and Relative, an auto
power off with disable feature, and dual sensitivity frequency functions (electrical/electronic).
