Operation
Span Cal Run screen:
The beginning span value is shown in the Gas display box along
with a span in progress icon that constantly updates as the calibration
proceeds.
The temperature of the TC detector is displayed to the right along
with a simulated thermometer. As the span reading settles, the screen
displays and updates information on Slope. Spanning automatically
ends when the span output corresponds, within tolerance, to the value of
the span gas concentration. Then the instrument automatically returns to
the Main screen.
The following items are contained within the Span calibration auto
mode run screen:
1. Calibration is in progress icon.
2. Gas concentration ppm or % values.
3. Slope values
4. Calibration status bar
5. Temperature reading status.
The Calibration in Progress icon will appear only in the Auto
calibration mode. It means that a calibration is in progress. When the
calibration is finished or if an error occurs, the icon will stop refreshing.
The current concentration (in percent or ppm) will be updated in
the Gas field as will the slope as calibration proceeds.
