If you on looking for an Amprobe AMP-330 TRMS Motor Maintenance Clamp Meter for the electrical motor part and HVAC investigation in tall voltage industrial environments, the AMP-330 Clamp Meter is the best clamp meter for the job. It is the best clamp meter in the AMP-300 Series stock including all the features of the AMP-320 gain a operate fresh, pinnacle sticking to, CAT IV 600 V, CAT III 1000 V safety rating and large 2.0 inch (51 mm) jaw. HVAC technicians will locate the temperature and capacitance measurements they habit gain DC Microamps for psychoanalysis flare sensors. It then had core motor investigation capabilities such as motor rotation, 3-phase sequence scrutinize and inrush current measurement for motor launch-happening monitoring. The low codicil filter allows you to expertly group current and voltage in excuse to adaptable frequency drives. The Amp-Tip pretense allows for precise measurement of current the length of to the tenth of an Amp, enabling accurate current measurement of both large and small diameter wires. It plus offers a full range of within plenty limits multimeter features, including AC/DC current, AC/DC voltage, frequency, True-RMS, non-admission voltage detection, resistance, and continuity.
