System Status Messages (HOME Screen)
While working from the HOME screen, messages that are displayed on
the right side of this screen indicate the current operating status (mode)
of the analyzer, also known as System Status or System State. Please refer
to supplemental material/documentation for any modes not described
below. Messages that can be displayed here include:
Not Ready
During this state, the analyzer is not measuring sample fluid due to
alarm conditions that must be resolved before it will resume normal
sampling operation.
Sample Flush
Indicates the analyzer is allowing sample fluid into the sample system.
There will be a short delay before it reaches the Measuring Cell, where
the analyzer begins measuring the sample.
Measure
Indicates the analyzer is measuring analyte values.
Span Fluid Flush
Indicates the sample system is being flushed with Span fluid (span
fluid valve is open). The valve will close when the system state chang-
es to Measure mode.
Span
This occurs following the Span Fluid Flush and indicates the analyzer
is being spanned. When complete, the span fluid valve is closed.
Zero Fluid Flush
Indicates the sample system is being flushed with Zero fluid (zero
fluid valve is open). The valve has to be closed by changing the system
state to Measure or Span mode.
Zero
Indicates the analyzer is being zeroed. During this function, the zero
fluid valve remains open until the Zero is complete. The Zero consists
of an average reading of a factory-set number of readings (usually 10
to 90; default = 60). The valve has to be closed by changing the system
state to Measure or Span mode.
Span Hold
Indicates the analyzer is measuring concentration with the span
fluid valve open. To leave this state, the analyzer must be manually
changed to another state from the Calibration screen.
Zero Hold
Indicates the analyzer is measuring concentration with the zero
fluid valve open. To leave this state, the analyzer must be manually
changed to another state from the Calibration screen.
