The Greenlee CMH-1000 (52066373) True-RMS AC HVAC Clamp Meter, 1000A AC, 1000V AC/DC, is a hand-held testing device with the following measurement capabilities: AC and DC voltage, AC current, AC current AmpTip, frequency, non-contact electric field (EF) detection, resistance, and capacitance. It also checks diodes and verifies continuity. The meter is designed to be placed on or removed from insulated or uninsulated conductors.
The CMH-1000 meter is suitable for all AC current measurement applications up to 1000A. It also performs three terminal phase sequence and motor rotation testing. HVAC measurements include capacitance, temperature, and DC microamps.
