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 DIV 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
(A - B)
C
(Calc Hi - Calc Lo))
PV or SP = K
CONST K2
0.001 to 1000
WEIGHTED AVERAGE RATIO OR K CONSTANT
FOR MATH SELECTIONS - Only applicable for
algorithms "WTD AVG" or Math selections
"MUL DIV ", "MULTIPLY ", "MULT DIV", or
"MULTIPLY"
