Controller / User Interface | 4-21
Calibration Actions Screen
The Calibration action screen displays all of the available analyzer calibra-
tion functions and allows the user to initialize the calibration functions.
Figures 4-17a and 4-17b illustrate the differences between analyzers that
use single-species spanning and those that use multi-species spanning.
Start zero calibration
This function forces the analyzer into the Zero calibration portion of
the normal operating sequence, starting with the “Zero Flush” mode,
then “Zero.” The analyzer zero is automatically adjusted based on the
average reading during the zero calibration.
Select Span Fluid (for applications that require multiple span fluids)
This function is used in applications where multiple span fluids are
required. The span fluid connected to the Cal (Span) Fluid Inlet port
must correspond to the fluid selected from the options listed under
this parameter.
To select a span fluid, press ENTER to go into edit mode. Use the UP/
DOWN arrow key to select the fluid you wish to span and then press
ENTER to select the span fluid. Next, select Start span calibration and
press ENTER to start the span.
Start span calibration
This function forces the analyzer into the Span mode of the normal
operating sequence, starting with the “Span Fluid Flush” mode. The
analyzer span (calibration) is automatically adjusted based on an inte-
grated reading during the span calibration. After the span is complete,
the analyzer will return to normal operation (Measure mode).
