The Fluke 1736 and 1738 Three-phase Power Quality Loggers are versatile, three-phase Fluke Connect-compatible power loggers for conducting energy, load and power quality studies.
  • Key measurements: Automatically capture and log voltage, current, power, harmonics and associated power quality values, and capture dips, swells, and inrush currents with event waveform snapshots and high-resolution RMS profiles
  • Convenient instrument powering: Power instrument directly from the measured circuit
  • Energy Analyze Plus application software: Download and analyze every detail of energy consumption and power quality state of health with our automated reporting and use the integrated power quality health summary to get an at-a-glance understanding of system health


  • DMM and a loop calibrator in one rugged, handheld tool
  • Provides a precision 1000 V, 440 mA True-RMS digital multimeter designed to meet 1000 volt IEC 1010 CAT III standards
  • Features a clear LCD with backlight; 4,000 counts (30,000 counts for DC current)
  • Performs frequency measurements to 20 kHz


Solve power problems you meet in your daily work, now that electrical loads in industrial and commercial buildings are often too complex to be calculated by the classical model of power.
Understand the major elements that affect power quality with our online webcast and supporting guidebook:
  • particularly inductive loads
  • harmonic distortion
  • three-phase power unbalance


Discover sources of electrical energy waste, identify energy savings opportunities, and conduct load studies.
  • Key measurements: Automatically capture and log voltage, current, power, power factor, energy and associated values
  • Convenient instrument powering: You can power the instrument directly from the measured circuit instead of mains outlets
