VERIFY SETUP
UP/DOWN to select and Enter VERIFY to check whether the linearization has been accomplished satisfactorily.
Dpt | INPUT | OUTPUT |
Ø | Ø.ØØ | Ø.ØØ |
The leftmost digit (under Dpt) is the number of the data point being moni- tored. Use the UP/DOWN 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.
If the OUTPUT value shown is not correct, the linearization must be correct- ed. 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 the curve. The user decides on the number of points, based on the precision re- quired.
The manual mode only requires entering the values for each correction point into the microprocessor via the front panel buttons. Again, the number of points required is determined by the user.
Note: Before performing section 4.8.2 or 4.8.2.3, you must check to ensure that your calibration gases or points are between low end and high end of the range setup. All correction points must be between the Zero and the Span concentration. Do not enter the Zero and Span points as part of the correction
4.8.2.2 Manual Mode Linearization
To linearize manually, you must have previous knowledge of the nonlinear
