Model 43i Trace Level-Enhanced Instruction Manual
The Power-Up screen is displayed on power up of the Model 43i Trace
Level-Enhanced. The Self-Test is displayed while the internal components
are warming up and diagnostic checks are performed.
The Run screen displays the SO
time and alarm status, and optional zero/span sample solenoid valves, if
installed. 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 CO "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
arrows will toggle between high and low concentrations. The
example that follows shows the Run screen in single range mode.
