Default operation is for COMPASS for Pressure (or Flow) to set the Status of each point in the test to "T" if it is out of tolerance, and blank if it is in tolerance. This COMPASS Report Editor Data File macro check the status of each point in the data file and changes it to PASS or FAIL, and it determines an overall test Pass/Fail status.
This is useful is you want to log default COMPASS Status (blank, T, R, r, t) in the data file but also want to show Pass or Fail in the calibration report for Status. For more information on default Status values search the COMPASS help file for "Status".
