Whether you quirk an amp clamp for HVAC, general electrical, or motor psychoanalysis applications, the Amprobe AMP-310 TRMS Motor Maintenance HVAC Clamp Meter, as soon as its large backlit display, has the features you obsession. HVAC technicians will locate the temperature and capacitance measurements they compulsion lead DC Microamps for laboratory analysis blaze sensors. It in addition to had core motor investigation capabilities such as motor rotation, 3-phase sequence scrutiny, and inrush current measurement for motor launch-happening monitoring. The low adding together filter allows you to proficiently play a role current and voltage regarding changeable frequency drives. The Amp-Tip do something allows for altering measurement of current all along to the tenth of an Amp, enabling accurate current measurement of both large and little diameter wires. It moreover offers a full range of adequate multimeter features, including AC current, AC/DC voltage, frequency, True-RMS, non-retrieve voltage detection, resistance, continuity, and a CAT III 600 V safety rating.
