3.3.5 The Model Screen
Move the < > arrow key to MORE and press Enter. With MODEL
blinking, press Enter. The screen displays the manufacturer, model, and
software version information.
3.3.6 Checking Linearity with ALGORITHM
From the System Function screen, select ALGORITHM, and press Enter.
sel rng to set algo:
—> Ш1 Ш2 Ш3 <—
Use the < > keys to select the range: 01, 02, or 03. Then press Enter.
Fluid Use: SO2
Range:
Ø — 10%
Press Enter again.
Algorithm setup:
VERIFY SET UP
Select and Enter VERIFY to check whether the linearization has been
accomplished satisfactorily.
Dpt INPUT OUTPUT
Ш Ш.ШШ Ш.ШШ
The leftmost digit (under Dpt) is the number of the data point being
monitored. Use the DÑ 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 fluid.
The OUTPUT value is the output of the linearizer. It should be the
ACTUAL concentration of the span fluid being simulated.
If the OUTPUT value shown is not correct, the linearization must be
corrected. Press ESCAPE to return to the previous screen. Select and Enter
SET UP to Calibration Mode screen. (set-up will not work without a PC
being connected to the analyzer)
Select algorithm
mode : AUTO
There are two ways to linearize: AUTO and MANUAL: The auto
mode requires as many calibration fluides as there will be correction points
along the curve. The user decides on the number of points, based on the preci-
sion required.
