FLIR CM65 True RMS 600A Solar Clamp Meter with METERLiNK



CM65 True RMS 600A Solar Clamp Meter with METERLiNK by FLIR

The CM65 is a rugged clamp meter designed to meet the challenges of solar installation, maintenance, and repair. This clamp meter comes with quick-connect MC4 test leads that improve the accuracy and safety of DC voltage measurements on solar panel strings and inverters. With the CM65, you can validate AC output and inverter efficiency and then store readings to the internal memory. Share data wirelessly via METERLiNK® or monitor measurements live on a smartphone running the FLIR Tools® mobile app. Photovoltaic (PV) installers can trust the CM65 as their go-to tool for accelerating and simplifying photovoltaic panel testing on new and existing solar panels.


  • Trust AC voltage and current measurements from inverters and mains are accurate with True RMS
  • Eliminate errors from residual ghost voltage using LoZ (low impedance) mode
  • Get sharp ±1.5% accuracy when taking AC and DC current readings
  • Capture the smallest voltage fluctuations when calibrating equipment using the CM65's millivolt function


  • Reduce the time needed for live/dead testing with included MC4 test leads
  • Gain quick insights with Data Hold, Min/Max readings, and relative mode to zero the meter
  • Troubleshoot string connections and components with a Continuity test mode
  • Measure resistance, frequency and temperature
  • Easily clamp around wires with the generous jaw (30 mm) and ergonomic design


  • Take measurements, document results, and then share them on the go
  • Identify trends and anomalies by data logging directly to the internal memory
  • View readings right on your mobile device using the CM65's METERLiNK® and the FLIR Tools® Mobile app on the roof, on the ground, or anywhere on a job site
