AMP-300 Series Motor Maintenance
TRMS Clamp Meters

If you test motors, verify and install electrical systems or work on HVAC equipment – or maybe do all three – you will appreciate the versatility and accuracy of an AMP-300 Series TRMS Clamp Meter.

Offering a third terminal for determining 3-phase sequence and motor rotation, AMP-300 clamp meters are ideal for all motor maintenance applications. They also feature an amp-tip for accurately testing 10 gauge or smaller wires, inrush current to validate whether motors have the required current to start-up, and True-RMS for noisy environments.

Designed for modern electrical environments, the AMP-300 clamp meters provide professional features and capabilities to make your job easier.

Put the AMP-300 Series to Work

  • Accurate measurement of current, voltage and frequency, including distorted, non-sinusoidal signals (True-RMS function) and variable frequency drive (low pass filter).
  • Capacitance measurement for start and run motor capacitors.
  • Resistance and continuity verifies quality of electrical connections and proper motor and transformer coils operation.
  • 3-phase Motor and Phase Rotation ensures motors are not spinning in the reverse direction, which could result in damaging the motor or connected equipment.
  • Low Pass filter measures current and voltage on variable frequency drives (motors with speed controlled by frequency).
  • DC Microamps output tests the proper operation of the flame sensor safety system in gas appliances.
  • Inrush current measurement verifies motors are receiving the required inrush current to support proper motor start.
