To access the AutoCal Timing screen, press from the Calibration Setup menu. All
values on the screen are expressed in seconds.
To navigate between parameters, use the up or down arrow to move
the highlight to the field you intend to change.
Press Enter to open the field and change the value (seconds).
Press Enter again to close the field after you have made your change.
A sequenced auto calibration consists of two cycles: Zero and Span. In both cases, the
cycle duration is equal to the sum of the Purge Before, Calibration and Verification
times. The Total Auto Calibration time is equal to the sum of the Zero and Span cycle
times plus the Purge After time. See the example above.
NOTE: Auto Calibration Timing determines the length of time it takes the analyzer to
perform the Zero and Span cycles during a sequenced auto calibration.
