    INFICON Operation | 5 5.3.12 Calibration (adjustment) Calibration is interpreted differently in different countries and applications. Throughout this document we therefore use the following definitions: Function Test: Exposing to given gas(es) checking if accuracy of a certain measurement is within specified accuracy and to judge weather calibration adjustment is needed.
  • Page 82 5 | Operation INFICON • Universal (low range) - weekly For calibration adjustment of Universal (low range) you need one, two or three gases as specified in section “Concentration of calibration and test gases”, see Concentration of calibration and test gases [} 35].
  • Page 83 INFICON Operation | 5 The methane calibration is possible with gas mixtures in synthetic air only. The natural background of CO (typically 400 ppm) in ambient air will offset the calibration. Fresh air exposure should, however, always be by ambient air.

  • Page 84: Standard Calibration Procedures

    5 | Operation INFICON 5.3.12.1 Standard calibration procedures Prepare calibration For a complete calibration you need the gases listed, see "Concentration of calibration and test gases [} 35]". It is not necessary that you calibrate all modes at the same time.

  • Page 85: Setting Of Calibration Gas Concentrations

    INFICON Operation | 5 • The gas flow delivered by the calibration station must be higher than the flow aspired by the leak detector. Set the gas flow to at least 80 l/h. • The gas must be delivered at ambient pressure (i.e., do not push gas into the leak detector).

  • Page 86: Adjust Calibration Reminder

    5 | Operation INFICON Set the exact gas concentration value via drop-down menus. The leak detector shows the gas to adjust in the window and the currently stored concentration appears just below the setting line. You cannot set the concentration outside the range.
