Auto Calibration Timing
→ → → →
Auto Calibration Timing determines the length of time it takes the analyzer to
perform the Zero and Span cycles during a sequenced auto calibration. To access the
AutoCal Timing screen, press from the Calibration Setup menu. All values on the
screen are expressed in seconds.
Each Channel will have its own set of values. Use the left or right arrow keys to
select the desired component.
To navigate between parameters, use the up or down arrow to move the
highlight to the field you intend to change. Press to open the field and change the
value (seconds). Press 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.
