Clamp-on power quality analyzer model HT9020 has been designed for measuring DC, AC+DC TRMS current up to 1000A according to CAT IV 600V in compliance with standard IEC/EN61010-1


  • DC and AC+DC TRMS voltage
  • DC and AC+CD TRMS current
  • Phase sequence and conformity test
  • AC powers and power factor on single-phase and/or balanced three phase systems
  • AC energies on single-phase and/or balanced three-phase systems
  • DC power
  • AC voltage harmonics up to 25° order and THD%
  • AC current harmonics up to 25° order and THD%
  • Frequency on voltage (with test leads) and current (with clamp jaw)
  • Resistance and continuity test
  • Electric motor starting currents (Dynamic Inrush)
  • Detection of AC voltage with and without contact with built-in sensor

HT9020 Clamp Meter with Powers/Harmonics and Inrush Currents carries out measurements of Active, Reactive and Apparent Power and Energy, voltage and current harmonic analysis up to the 25th order with THD% calculation, in single-phase or three-phase balanced systems. It also tests phase sequence and phase conformity by 1-lead measuring method as well as detects any event related to electric motor starting currents (DYNAMIC INRUSH).  DYNAMIC INRUSH™ permits to measure inrush currents with user-defined time frames, providing measurements more reliable than standard fixed time-frame testers. The user has the chance to recall and display the measurement by applying different time frames. For example, if the user carries out a measurement using a time frame of 100 ms, he can post-process the same measurement by applying a time frame of: 16,7, 20, 50, 100, 150, or 200 ms. This grants the utmost flexibility for each measurement, and prevents to measure again and again to get the real inrush current value.
