    Why is the data displayed on my Masibus PM2160-A inaccurate?
    • A
      Allison TaylorAug 3, 2025
      If the data displayed on your Masibus Measuring Instruments is inaccurate, there might be several reasons: * Incorrect setup values: Ensure that the correct values have been entered for the setup parameters, such as CT and PT ratings, and the system type. * Incorrect voltage inputs: Check the voltage input terminals to verify adequate voltage is present. * Improper wiring: Verify that all CTs and PTs are connected correctly, observing proper polarity, and that they are energized. Also, check the shorting terminals.

      If the display is blank with the backlight off after applying control power to the Masibus Measuring Instruments, the meter may not be receiving the necessary power. Verify that the line (L) and neutral (N) terminals are receiving the required power.
