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.

  • Measures AC/DC Current to 600 A and AC/DC Voltage to 600 V
  • Measures temperature from -40° to 752°F, (-40° to 400°C)
  • Measures DC Microamps output to test proper operation of the flame sensor on gas appliances
  • Measures capacitance, test diodes, and features a continuity beeper
  • Tests 3-phase sequence and motor rotation to ensure proper connection of a motor to a 3-phase system
  • Monitors inrush current during motor start-up
  • Features True-RMS sensing for accurate voltage measurements in noisy electrical environments
  • Amp-Tip function delivers precise low AC current measurements – 0 to 60 A
  • Includes a low pass filter to accurately measure voltage and current on variable frequency drives
  • Provides resistance and continuity measurement capabilities to verify the quality of electrical connections and the proper operation of motor and transformer coils
  • Provides data hold, relative zero, and MAX/MIN/AVG mode for quick analysis
  • Maximizes battery life with auto power off and low battery indicator
  • Backlit display for easy measurement viewing in bright and dim environments
  • CAT III 600 V safety rated
  • Accommodates conductors up to 1.37 inches (35 mm)
  • Includes test leads, batteries (installed), alligator clip set, banana plug K-type thermocouple, carrying case, and user manual
