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 PID/FID
FID: 500ppm PID: 100ppm
FID: 500ppm
Span Gas Concent Span Conc:1=Both
Enter=New conc 2=PID 3=FID
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 PID/FID
FID: 500ppm PID: 100ppm
FID: 500ppm
Span Pt3 (Up/Dn) Span Pt3 (Up/dn)
Enter=New conc 1=Both 2Pid 3Fid
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:
