1. Purge Before : the operator can set the amount of time necessary to flush the
analyzer with calibration gases. This will ensure that there are no other gases
remaining in the analyzer during the calibration process.
2. Calibrating Time : during this 10-second time, the analyzer will calculate new
offset and gain factors. The calibrating time is factory-set at 10 seconds and
cannot be changed by the operator.
3. Verifying Time: during this time the measured value is checked to make sure it
does not deviate outside the upper or lower limit specified by the Maximum
Verifying Error . The verifying time is typically set for 10 seconds.
4. Purge After : the operator can set the time needed to flush any remaining
calibration gases out of the analyzer before the In Cal Status is released and the
measurement status is set. Purge after starts after the last component has finished
verifying.
After the Auto Calibration Timing has been set, press to save the changes.
