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 set the INPUT value for the lowest concentra- tion into the first point. ENTER to move to OUTPUT field. Use the UP/ DOWN key to set the OUTPUT value, the lowest concentration into the first point. ENTER to accept the first setting.

After each point is entered, the data-point number increments to the next point. Moving from the lowest to the highest concentration, use the UP/DOWN 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, ESCAPE. The message, Completed. Wait for calcula- tion, appears briefly, and then the main System screen returns.

To end the session, send:

4.8.2.3 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.
