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, 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 (PM16 Series). This software is not compatible with the 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
