LO SEL
(See Note 2)
INPUT LOW SELECT WITH RATIO AND BIAS—
This selection specifies the PV or SP as the lower of
Input A or Input B. The following formula applies:
Alg1 = lower of (Input A x Ratio A + Bias A) or (Input B x Ratio B + Bias B)
√MuDIV
(See Note 1)
MULTIPLIER DIVIDER WITH SQUARE ROOT—
The following formula applies:
Alg1 = K * Sq.Rt. {(Input A x Ratio A + Bias A) x (Input C x Ratio C + Bias C) / (Input B * Ratio B + Bias
B)}
x (Calc Hi – Calc Lo) + Alg1Bias
See Figure 3-1 at the end of this section for an example of Mass Flow
Compensation using the Multiplier/Divider Algorithm.
√MULT
(See Note 1)
MULTIPLIER WITH SQUARE ROOT—The following
formula applies:
Alg1 = K x Sq.Rt. {(Input A x Ratio A + Bias A) x (Input B x Ratio B + Bias B) x
(Input C x Ratio C + Bias C)} x (Calc Hi – Calc Lo) + Alg1Bias
MuDIV
(See Note 1)
MULTIPLIER DIVIDER—The following formula
applies:
Alg1 = K x [{(Input A x Ratio A + Bias A) x (Input C x Ratio C + Bias C)} / (Input B x Ratio B + Bias B)]
x (Calc Hi – Calc Lo) + Alg1Bias
MULT
(See Note 1)
MULTIPLIER—The following formula applies:
Alg1 = K x [(Input A x Ratio A + Bias A) x (Input C x Ratio C + Bias C) x (Input B x Ratio B + Bias B)]
x (Calc Hi – Calc Lo) + Alg1Bias
CARB A
CARBON POTENTIAL A—Make this selection if
you have a Cambridge or Marathon monitor type
Zirconium Oxide sensor. It should also be used if
using an Automotive probe (no thermocouple). This
algorithm requires a temperature range within the
region of 1500 to 2000°F. See
Carbon/Oxygen/Dewpoint Notes.
CARB B
CARBON POTENTIAL B—Make this selection if
you have a Corning type Zirconium Oxide sensor.
This algorithm requires a temperature range within
the region of 1500 to 1800°F. See
Carbon/Oxygen/Dewpoint Notes.
CARB C
CARBON POTENTIAL C—Make this selection if
you have an A.A.C.C. type Zirconium Oxide sensor.
This algorithm requires a temperature range within
the region of 1500 to 1900°F. See
Carbon/Oxygen/Dewpoint Notes.
