Because of timing requirements, sequenced calibrations are generally only used when the
analyzer is controlling the flow of zero and span gases into the analyzer. 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 THC 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 Zero Range1 Calibrating). 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:
Analyzer Mode
Expected Span Concentration
Countdown Timer
Current Date and Time
