Operation
Software Overview
Power-Up Screen
The Power-Up screen is displayed on power up of the Model 17i. The SelfTest is displayed while the internal components are warming up and
diagnostic checks are performed.
Please wait while booting...
Run Screen
The Run screen displays the NO, NO2, NOx, NH3, and Nt concentrations.
The status bar displays optional zero/span solenoid valves, if installed, time,
and alarm status. The word “SAMPLE” on the bottom left of the display
indicates the analyzer has the span/zero valve option and is in “SAMPLE”
mode. Other modes appear in the same area of the display as “ZERO” or
“SPAN”. For more information about the optional solenoid valves, see
Chapter 9, “Optional Equipment”.
When operating in dual or auto range mode two sets of coefficients are
used to calculate the NO, NO2, NOx, NH3, and Nt “High” and “Low”
concentrations. Also, two averaging times are used—one for each range.
The title bar indicates which range concentrations are displayed. The words
“LOW RANGE CONCENTRATION” on the top of the display indicates
that the low concentration is displayed. In dual range mode, pressing the
and
arrows will toggle between high and low concentrations.
The example below shows the Run screen in single range mode.
