19. OK FIELD CALIBRATION Field calibration allows simple calibration to be carried out in the field without the use of additional test equipment Other calibration procedures require the use of the GMI Manual Calibration software or the Workshop System There are fundementals in terms of instrument calibration that should be noted The gas should be of known traceable quality and have total analysis The gas should be applied in the same manner as the instrument is used e g at a known pressure which is constant and around or slightly above normal atmospheric pressure The use of demand type regulators is not recom mended on instruments with Oxygen or Toxic cells since these are affected by pressure pulses In Field Calibration Mode FCM the buttons perform the functions indicated in CAL Mode or SPAN Mode as shown in Figure B 1 B 1 GASURVEYOR 3 500 USER HANDBOOK CAL Mode SPAN Mode V PUMP V INCREASE Button 1 EXIT SPAN ABANDON Y RANGE V DECREASE Button 2 ZERO Y SAVE CALIBRATE ALARM Figure 1 Button Functions To simplify button operation when calibrating the instrument an overlay card shown in Figure B 2 is available and can be placed over the top face of the instrument to identify calibration button functions Contact GMI for details r TE FLL C LR ETE mann Figure B 2 Instrument Overlay Card B 2 FIELD CALIBRATI
