Thermal Conductivity Analyzer

4.8.2 The Curve Algorithm Screen

The Curve Algorithm is a linearization method. It provides from 1 to 9
intermediate points between the ZERO and SPAN values, which can be normal-
ized during calibration, to ensure a straight-line input/output transfer function
through the analyzer.
Each range is linearized individually, as necessary, since each range will
usually have a totally different linearization requirement. Before setting the
algorithm curve, each range must be Zeroed and Spanned.
To linearize the ranges, you must first perform the four steps indicated at
the beginning of section 4.8 Programming. You will then be in the second
System menu screen.
From the System Function screen, select ALGORITHM, and press
Enter.
Use the < > keys to select the range: 01, 02, or 03. Then press Enter.
Press Enter again.
Select and Enter VERIFY to check whether the linearization has been
accomplished satisfactorily.
The leftmost digit (under Dpt) is the number of the data point being moni-
tored. Use the Δ∇ keys to select the successive points.
The INPUT value is the input to the linearizer. It is the simulated output of
the analyzer. You do not need to actually flow gas.
The OUTPUT value is the output of the linearizer. It should be the ACTU-
AL concentration of the span gas being simulated.
