3.8.2.1 Manual Mode Linearization
To linearize manually, you must have previous knowledge of the nonlinear
characteristics of your gases. You enter the value of the differential between the
actual concentration and the apparent concentration (analyzer output). TAI has
tabular data of this type for a large number of gases, which it makes available to
customers on request. See Appendix for ordering information. To enter data:
From the System Functions Screen—
1. Select ALGORITHM , and Enter.
2. Select and Enter SETUP.
3. Enter MANUAL from the Calibration Mode Select screen.
Dpt INPUT OUTPUT
Ø Ø.ØØ Ø.ØØ
The data entry screen resembles the verify screen, but the gas values can
be modified and the data-point number cannot. Use the UP/DOWN key to
modufy the input field, then Enter to modify the output field, Enter again to move
to the next data field.
After each point is entered, the data-point number increments to the next
point. Moving from the lowest to the highest concentration.
Dpt INPUT OUTPUT
0 Ø.ØØ Ø.ØØ
Repeat the above procedure for each of the data points you are setting (up
to nine points: 0-8). Set the points in unit increments. Do not skip numbers. The
linearizer will automatically adjust for the number of points entered.
When you are done, ESCAPE. The message, Completed. Wait for
calculation, appears briefly, and then the main System screen returns.
To end the session, send:

to the analyzer from the computer.
3.8.2.2 Auto Mode Linearization
To linearize in the Auto Mode, you must have on hand a separate calibra-
tion gas for each of the data points you are going use in your linearization. First,
