Setting Up Analyzer Calibration Functions
This section describes the commonly used functions and controls available
in CAL mode.
Flow Control (Sample) Modes
The Flow Control (FlowCtrl) mode sets the state of the sample gas flow,
and can be controlled automatically by the analyzer (Analyzer Control
mode) or manually forced by the operator to Continuous Sample or
Continuous Backpurge/Zero Flow mode.
The screen will display a character on the top-left line that indicates the
current operating mode and either automatic or manual control:
