5.9 Selecting a Computed Value to Be Displayed

Purpose

The Analyzer/Controller can calculate and display a computed value. The available values are:

Cell1

∙RATIO: ratio between the values measured by the cells; Cell2

∙DIFFERENCE: difference between the values measured by the cells; Cell1 − Cell2


		Cell1	x100
∙
	%PASSAGE: computed percent passage: Cell2
		(1 −		Cell1	)x100
∙
	%REJECTION: computed percent rejection: Cell2

∙PPMCO2: computed parts per million carbon dioxide (standard range analyzers only) Appendix B includes examples of applications using these values.

ATTENTION

If a computed value is used, it is significant which cell is considered “Cell 1” and which is “Cell 2”. This must be taken into account when wiring the inputs. See 6.3 for details.

Procedure

Use the procedure in Table 5-9 to specify a computed value.
