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 linearizerwillautomaticallyadjustforthenumberofpointsentered.

When you are done, Press ESCAPE. The message, Completed. Wait for calculation, appears briefly, and then the main System screen returns.

3.8.2.2 Auto Mode Linearization

To linearize in the Auto Mode, you must have on hand a separate

calibration fluid for each of the data points you are going use in your linear- ization. First, the analyzer is zeroed and spanned as usual. Then, each special calibration fluid, for each of the intermediate calibration points, is flowed, in turn, through the sensor. As each fluid flows, the differential value for that intermediate calibration point is entered from the front panel of the analyzer.

Note: The span fluid used to span the analyzer must be >90% of the range being analyzed.

Before starting linearization, perform a standard calibration. See section 4.4. To enter data:

From the System Functions screen—

1.Use < > to select ALGORITHM , and Enter.

2.Select and Enter SETUP.

3.Enter AUTO from the Calibration Mode Select screen. The Auto Linearize Mode data entry screen appears.

19.5ppm SO2 Input(Ø) :20.00

5.Use the DÑ keys to set the proper value of calibration fluid, and Enter. Repeat this step for each cal-point number as it appears in the Input (x) parentheses.

6.Repeat step 5 for each of the special calibration fluides, from the lowest to the highest concentrations. Press Escape when done.
