Fluke 345

Power Quality Clamp Meter

The Fluke 345 is ideal for troubleshooting and logging data in power electronics, including variable frequency motor drives, high-efficiency lighting, and other loads that use switching electronics.

The multifaceted Fluke 345 works as a power quality logger, clamp meter, oscilloscope, data logger, and digital power meter. It also doubles up as a Cat IV power analyzer. This all-in-one handheld meter saves you from buying separate equipment for every job in commercial, industrial, and residential environments.

Fluke 345 Clamp Meter Features and Specifications 

  • Analyze the harmonic spectrum for disruptive issues in critical equipment with a high-quality color display
  • Remove high-frequency noise using a low-pass filter
  • High EMC immunity design
  • Enable long-term power quality data logging and identify intermittent faults with internal memory feature
  • Hall-effect design helps measure DC current without breaking the circuit
  • Inrush capture: Analyze start-up current for spurious resets and nuisance circuit-breaker tripping (3 to 300 seconds)
  • Check electrical system capacity before loading
  • Directly measure DC ripple (percent) for batteries and DC systems
  • Power log software: View trends and screenshots, analyze and create reports, and download via USB. View graphs and generate reports
  • Three-phase power measurement capability for balanced loads
  • Accurate low-pass filter even in noisy environments with distorted waveforms on electronic loads
  • Clamp-on measurement of AC current (1,400A rms) and DC current (0A to 2,000A rms) without breaking the circuit
  • Typical battery life: 10 hours (full backlight) and 12 hours (reduced backlight)
  • Operating temperature range (indoor use): 0 degree C to 50 degree C
  • Crest factor: 1.1 greater than or equal to CF < 3 ( /-3 percent rdg /-5 digits), 3 to CF less than less than 0.99
  • Weight: 820g

What Are Some Applications of the Fluke 345 Clamp Meter?

  • Setup and troubleshoot variable frequency drives, UPS systems, and electronic lighting by measuring key power quality parameters
