Equipped with new functionality

  • NEW – Now compatible with Fluke Connect mobile app and all Fluke FC enabled test tools with optional ir3000 FC infrared connector (sold separately).
  • NEW – Let your team see what you see in an instant with ShareLive™ video call (requires Fluke Connect mobile app and ir3000 FC wireless connector).
  • TrendCapture graphically displays logged data session to quickly determine whether anomalies may have occurred.
  • Zoom on trend provides unprecedented ability to view and analyze TrendCapture data; zoom in up to 14 times.
  • Selectable ac filter (smoothing mode) helps display a steadier reading when the input signal is changing rapidly or noisy.
  • Adjustable recording and auto hold thresholds, specify a percentage change in the readings that begins a new event.
  • Large 50,000 count, 1/4 VGA dot matrix display with white backlight.
  • Logging function with expanded memory for unattended monitoring of signals over time. Using on-board TrendCapture users can graphically review logged readings without needing a PC. Store up to 15,000 recorded events.
  • Save multiple logging sessions before pc download is necessary.
  • Two terminal 50 ohm range with 1 milliohm resolution, 10 mA source current. Useful for measuring and comparing differences in motor winding resistance or contact resistance.
  • Low Pass filter for accurate voltage and frequency measurements at the same time on adjustable speed motor drives and other electrically noisy equipment.
  • LoZ Volts. Low impedance voltage function for eliminating ghost voltages. Also recommended when testing for absence or presence of live power.
  • On board help screens for measurement functions. Unsure about a function - go to that function and press the "i" button.
  • Real time clock for automatic time stamping of saved readings.
  • Relative mode to remove test lead resistance from low ohms or capacitance measurements.
  • True-RMS ac voltage and current for accurate measurements on non-linear signals.
  • Measure up to 10 A (20 A for 30 seconds).
  • 100 mF capacitance range.
  • Peak capture to record transients as fast as 250 μs.
  • Premium test leads and alligator clips included.
  • Amp jack plugs included.
  • Optional magnetic hanger for easy setup and viewing while freeing your hands for other tasks.
  • FlukeView forms enable you to document, store and analyze individual readings or a series of measurements, then convert them into professional-looking documents.
  • Limited lifetime warrantty.
