The data entry screen resembles the verify screen, but the gas values can

be modified and the data-point number cannot. Use the

< >

keys to toggle

between the INPUT and OUTPUT fields. Use the

Δ∇ keys to set the value for

the lowest concentration into the first point. Then press

Enter

.

After each point is entered, the data-point number increments to the next

point. Moving from the lowest to the highest concentration, use the

Δ∇ keys to

set the proper values at each point.

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, Press

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,
the analyzer is zeroed and spanned as usual. Then, each special calibration gas,
for each of the intermediate calibration points, is flowed, in turn, through the
sensor. As each gas flows, the differential value for that intermediate calibration
point is entered from the front panel of the analyzer.

Note: The span gas used to span the analyzer must be >90% of the

range being analyzed.
