Definition

INPUT ALGORITHM 2— The selections from which to choose are listed to the left.

The formulas are the same as shown for IN ALG 1.

*ATTENTION Selection A–B/Calgorithm subtracts Input B with Ratio/Bias from Input A with Ratio/Bias and divides the result by Input C with Ratio/Bias using engineering units.

EXAMPLE:

PV or SP = K (A–B) (Calc Hi – Calc Lo)

C

WEIGHTED AVERAGE RATIO OR MASS FLOW ORIFICE CONSTANT (K) FOR MATH SELECTIONS— Only applicable for algorithm W AVG or General Math selections  MuDIV,  MULT, MuDIV, or MULT.

CALCULATED VARIABLE HIGH SCALING FACTOR FOR INPUT ALGORITHM 2— Does not apply to Feedforward algorithms. Range is used for either PV or RSP, depending upon Algorithm application.

CALCULATED VARIABLE LOW SCALING FACTOR FOR INPUT ALGORITHM 2— Does not apply to Feedforward algorithms. Range is used for either PV or RSP, depending upon Algorithm application.

ALGORITHM 2, INPUT A SELECTION will represent one of the available selections.
