Note If your instrument is equipped with dual detectors, you may choose
to calibrate the FID separately or PID/FID together.
Note If your instrument is configured for multiple span points, be sure to
set the concentration for ALL span points.
1. From the CAL CONFIG MENU (Page 1) display, press 2=Span concs.
The upper display (or two displays if the unit is a dual detector version)
will display the concentration value of your span gas (expressed as ppm
or %) as of the last calibration:
FID
FID: 500ppm
Span Gas Concent
Enter=New conc
If the TVA2020 is configured for multiple calibration points, the span gas
concentration values for Point #3 will be displayed. The Up and Down
arrow keys can be used to scroll through the span gas concentration values
for other points:
FID
FID: 500ppm
Span Pt3 (Up/Dn)
Enter=New conc
2. To change a span gas concentration value, choose the detector(s) of
interest if using a dual detector analyzer, or press ENTER if using a
single detector analyzer. The following display will appear:
