Voltage & Current Testing

Get control of power problems

43b_main[1]The Fluke 43 Power Quality Analyzer performs the measurements you need to maintain power systems, troubleshoot power problems and diagnose equipment failures.

  • Combines the most useful capabilities of a power quality analyzer, multimeter and scope
  • Calculates 3-phase power on balanced loads, from a single-phase measurement
  • Trends voltage, current, frequency, power harmonics and captures voltage sags, transients and inrush current
  • Monitoring functions help track intermittent problems and power system performance


  • Voltage, current, and power harmonics
  • Up to 51st harmonic
  • Total harmonic distortion (THD)
  • Phase angle of individual harmonics


  • Watts, power factor, displacement power factor (cos Θ), VA and VAR
  • Voltage and current waveforms

Three phase

  • On-screen graphics show you how to set up 3-phase power measurements

Sags and swells

  • Measurements are always automatically recorded to instantly show changes over time
  • Use cursors to read time and date of sags and swells


  • Catch voltage transients and waveform distortion down to 40 nS
  • Catch and save up to 40 transients
  • Correlate the cause of transient with time and date stamps


  • Voltage and current waveforms
  • True RMS voltage and current
  • Frequency
