The Gas Flow Calibration menu is used to calibrate the gas flow controller
at 5, 20, 35, 50, 65, 80, and 95 percent of full-scale. Using a NIST
traceable flow meter, the accuracy of the controller can be calibrated to
about
±
1%, as opposed to the
±
2% accuracy rating when shipped from
the manufacturer. The gas flow calibration is visible only when the
instrument is in service mode. For more information of the service mode,
see “
Service Mode ” earlier in the chapter.
Note This adjustment should only be performed by an instrument service
technician. ▲
