If you’re looking for a versatile clamp-on amp meter for electrical motor maintenance and HVAC testing in high 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 line including all the features of the AMP-320 plus a work light, peak hold, CAT IV 600 V, CAT III 1000 V safety rating and large 2.0 in (51 mm) jaw. 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, and continuity.

The AMP-330 clamp meter comes with test leads, alligator clip set, banana plug Type-K thermocouple, two (2) AAA batteries (installed), user manual, and a carrying case.
