INP ALG2
ATTENTION
• All Input Algorithms
operate in engineering
units except Feed-
forward which operates
in percent of range units.
• For General Math
functions, when Input C
is disabled, the value of
Input C used in the
functions is
automatically set to 1.0.

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/C algorithm 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

(Calc Hi – Calc Lo)
MATH K2
0.001 to 1000 floating
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.
CALC HI
–999. To 9999. Floating
(in engineering units)
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.
CALC LO
–999. To 9999. Floating
(in engineering units)
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.
