Optical Power Monitor

The Optical Power Monitor (OPM) software provides remote control and monitoring of up to eight power and energy meters. This software is compatible with our Power Meter Consoles and Interfaces (PM100A and PM101 Series), Power and Energy Meter Consoles and Interfaces (PM100D, PM400, PM5020, PM100USB, PM103 Series, and legacy PM200), Position & Power Meter Interfaces (PM102 Series), Wireless Power Meters (PM160, PM160T, and PM160T-HP), and USB-Interface Power Meters and Photon Counter (PM16 Series, and SPCNT). This software is not compatible with the previous-generation PM320E Benchtop Power and Energy Meter, which uses a separate software package available here.

Key features include:

  • Control and Monitor up to Eight Power and Energy Meters Simultaneously via USB, RS232, or Bluetooth® Connections
  • Adjustable Digital Measurement Display
  • Analog Needle Display with Delta Mode
  • Acquire Measurement Statistics Over a Set Duration or Data Sample Size
  • Display and Log Sequential Measurements Over Time
  • Export Data Logs in .csv Format
  • Set Display Language to English, German, or Chinese
  • Manual Download Available Here
For users with custom software based on the PM100D.dll driver or who prefer the legacy Power Meter Software; it is also available by clicking here.
