This feature will operate when the probe type is set to AUTO .
  • Page 28: Measure Modes

    This method has been used in all Cygnus gauges since the late 1970s. Multiple echo mode will ignore surface coatings (Through Coating mode) there is no need to remove the paint to take a measurement.
  • Page 29: Echo-Echo Mode (Ee)

    Cygnus DIVE Operating Manual M3-DIVE-M-ENG_Iss9.docx However single echo mode will not ignore any surface coatings, so if you measure through a coating it will give an incorrect metal thickness measurement. If the surface coating is very thin (0.2mm / 0.01”) paint you can make an allowance for this error, but thicker coatings introduce too much error to be practical.
