This versatile clamp-on power meter offers a full range of diagnostics, including those that HVAC technicians need most—volts, amps, resistance, capacitance, DC microamps, in-rush current and temperature.
A great clamp-on multimeter choice for troubleshooting or maintaining air conditioning or motor efficiency, measuring phase rotation, and identifying harmonics. Convenient joystick enables quick single-handed function selection.
