The Number Span Pt screen is used to determine the number of span
points that will be used to calibrate your TVA2020. Choosing this selection
will produce the following screen:
FID
FID: 3
Span Gas Points
Enter=New Value
From this screen, you may choose which detector you wish to set the
number of span points for. Choosing one of these selections produces the
following screens:
FID
Number span pts:
FID: 3
Select: 1 to 9
From these screens, press the number of span points that you wish to use.
Both detectors can have up to 9 span points each, and they do not
necessarily need to have the same number of span points. When Both
option is chosen, a single value will be applied to both PID and FID.
The span gas concentration is the known concentration of the gas standards
used to calibrate your TVA2020. Methane in air is the recommended
calibration standard for the FID, and Isobutylene in air is the
recommended calibration standard for the PID. Other gases may be used if
desired.
