  • The ASVXL will display the Standard Value.  This is the sea level value of the standard being used and can be found on the label of the bottle.  If the standard value you are using is different, you must change the number here.
  • The ASVXL will display the Target Value.  
  • If your ASVXL has an on-board barometer, this number is calculated automatically and displayed later in the sequence.









 

  • Press the button on your True-Cal device or look at the chart on the Dry Gas tank label to get the Target (or Expected) Value of the standard.
  • Then enter the Target Value


NOTE:  Wet Bath Simulator users will not be asked about the Target Value since the Standard and Target values for a wet standard are the same.
