To initiate a sequenced calibration, press from the Automated Calibration menu.
Once the sequenced calibration is initiated, it will calibrate the analyzer in the current
mode and range. In this case the NO
x
mode is shown near the upper-left corner of the
screen.
A sequenced calibration has seven steps. The Current Status of each step is shown just
below the expected gas concentration (in this case, it is Purging with Sample). Each step
uses a countdown timer set up in
AutoCal Timing, located in the Calibration Setup menu.
The sequence (with the current range indicated) is as follows:
NOTE: Because of timing requirements, sequenced calibrations are generally used
only when the analyzer is controlling the flow of zero and span gases into the analyzer.
