Then the analyzer returns to the initial System screen.
4.3.6 The Model Screen
Scroll through the MAIN MENU to MODEL and Enter. The screen
displays the manufacturer, model, and software version information.
4.3.7 Checking Linearity with ALGORITHM
Use UP/DOWN control to select
ALGORITHM, and
Enter .
sel rng to set algo:
—> Ш1 Ш2 Ш3 <—
Use the UP/DOWN Control to select the range: 01, 02, or 03. Then
press Enter .
Gas Use: H2 — N2
Range: Ø — 10%
Enter again.
Algorithm setup:
VERIFY SET UP
Use UP/DOWN key to 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 UP/DOWN key 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
ACTUAL concentration of the span gas being simulated.
If the
OUTPUT value shown is not correct, the linearization must be
corrected. ESCAPE to return to the previous screen. Select and Enter
SET
UP to Calibration Mode screen.
Select algorithm
mode : AUTO
There are two ways to linearize:
AUTO and MANUAL: The auto mode
requires as many calibration gases as there will be correction points along
