Auto Mode Linearization - Teledyne 2010A Operating Instructions Manual

Thermal Conductivity Analyzer
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 ESCAPE. The message, Completed. Wait
for calculation, appears briefly, and then the main System screen returns.
To end the session:
If started with the RS-232, send:
to the analyzer from the computer.
If started through the front panel, turn the instrument off and back on.
Press the Enter key twice to return to the Analyze mode.
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 use 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.
