Infrared Gas Analyzer
From the MAIN MENU Screen—
1. Use UP/DOWN to select
2. Select and Enter
3.
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,
appears briefly, and then the main System screen returns.
To end the session, send:
to the analyzer from the computer.
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.
