Description
Whether you need an amp clamp for HVAC, general electrical or motor testing applications, the AMP-320 Clamp Meter, with its large backlit display, has the features you need. HVAC technicians will find the temperature and capacitance measurements they need plus DC Microamps for testing flame sensors. It also had core motor testing capabilities such as motor rotation, 3-phase sequence testing, and inrush current measurement for motor start-up monitoring. The low pass filter allows you to accurately measure current and voltage on variable frequency drives. The Amp-Tip function allows for precise measurement of current down to the tenth of an Amp, enabling accurate current measurement of both large and small diameter wires. It also offers a full range of standard multimeter features, including AC/DC current, AC/DC voltage, frequency, True-RMS, non-contact voltage detection, resistance, continuity and a CAT III 600 V safety rating.
