CAST AC/DC Clamp Volt/Amp Meter (Part #CMETER)

The CAST AC/DC Clamp Volt/Amp Meter (Part #CMETER) is the essential diagnostic tool for professional landscape lighting installers, service technicians, and maintenance crews. Designed specifically for low-voltage outdoor lighting systems, this versatile meter provides fast, accurate testing of AC and DC voltage, current, resistance, continuity, capacitance, and temperature—all in one compact instrument.

With True RMS (TRMS) technology and ±1.5% accuracy across its most commonly used operating range, the CMETER helps you troubleshoot installations, verify transformer output, measure fixture loads, diagnose voltage drop, and identify wiring issues with confidence.

Complete with test leads, a K-type thermocouple, carrying case, and a quick-reference wire sizing guide, the CAST AC/DC Clamp Meter is the one tool every lighting professional should keep in their service vehicle.
