3 Operation
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.
Before starting linearization, perform a standard calibration. See section
4.4. To enter data:
From the System Functions screen—
1. 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.
5. Use the UP/DOWN switch to set the proper value of calibration
gas, 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 gases, from the
lowest to the highest concentrations. Escape when done.
To end the session, send:
