5 Press the Send button to start the gain calibration.
After completion of the span calibration routine:
The validity of each new span calibration constant (CO
2
, CO, HC)
is checked.
New span calibration constants for the HC, CO and CO
2
channels
should not significantly differ from the factory span calibration
constants.
If a newly calculated span calibration constant does differ by
greater than ±30% from the original factory value, the
appropriate span fail status (CO
2
Span Fail, CO Span Fail, HC
Span Fail), is set true see figure 4.34.:
Figure 4.34. Status window showing a CO2 span failed.
If the NO channel is being span calibrated, the current full-scale NO
output is calculated and saved. If the current full-scale NO output is less
than or equal to a preset value (The Low NO Sensor Limit) the New NO
Sensor Required is shown in the Status window, see figure 4.13 .
