The Kyoritsu KEW 2431 is a compact, handheld digital clamp meter engineered specifically for measuring AC leakage currents in electrical systems. Its tear‑drop‑shaped transformer jaws accommodate conductors up to 24 mm in diameter, making it easy to clamp in crowded cable bundles or confined spaces without disconnecting wiring. Measurement ranges span 20 mA (0 – 19.99 mA), 200 mA (0 – 199.9 mA), and 200 A (0 – 199.9 A), selectable via a simple rotary switch.
A built‑in low‑pass filter (50/60 Hz mode) removes harmonics from inverter or switching‑regulator noise, ensuring accurate fundamental‑frequency readings. Readings are shown on a 3½‑digit LCD (max. 1999 counts) with an overrange “1” indicator, and the data‑hold button locks the displayed value for easy viewing in poorly lit or hard‑to‑reach locations. The meter automatically powers off after ~10 minutes to conserve two LR‑44 (or SR‑44) batteries, yet delivers up to 15 hours of continuous operation.
Designed to IEC 61010‑1 CAT III 300 V and pollution degree 2 standards, it offers robust safety in industrial environments. Housed in a shock‑resistant case with a protective barrier, the KEW 2431 weighs just 120 g (incl. batteries) and comes complete with a carrying pouch for field‑ready convenience.
Features:
- Digital clamp meter for AC leakage current measurement.
- Tear‑drop‑shaped jaws for tight‑space clamping.
- Data‑hold function for freezing readings.
- Filter function to remove inverter‑generated harmonics.
- Automatic power‑off to extend battery life.
- Safety design to CAT III 300 V, pollution degree 2 (IEC 61010‑1).
