In normal operation DGA monitor repeats the measurement cycle continuously. You can only start the measurement if DGA monitor is currently in standby.

  1. Start measurement from Control > Start Measuring.

    Since this is the first time measurement is started after initialization, the DGA monitor will perform autocalibration. Autocalibration improves measurement performance by adapting the DGA monitor to transformer oil conditions. After autocalibration, DGA monitor continues to measure normally.

    Autocalibration takes from 2 to 5 days depending on conditions. Measurements performed during autocalibration do not meet the accuracy and repeatability specifications and they should not be used for transformer diagnostics.

  2. Wait for the first measurement cycle to complete. Depending on the starting conditions, it may take up to 90 minutes. Verify that there are no oil leaks in the oil pipes or inside DGA monitor.
