Math Algorithm Notes:
1. Calculation ranges for the Math Algorithms are set via CALC HI and CALC LO parameters and
are between –999. and 9999. The SP High and Low values (SP Range) are independent of
these settings and can be any value between –999. and 9999.
2. The CALC HI and CALC LO values determine the range limits for the SP High and Low values
for the Weighted Average, Summer, Hi Select and Low Select algorithms.
3. If the Ratio for Input 2 is set to 0.0, then a constant value may be used for the Input 2 value via
the Input 2 Bias setting. For this configuration, the Input 2 low range and the Sooting diagnostic
messages are disabled.

Definition
PERCENT CARBON is only applicable when
Carbon Potential is selected. Enter the value in
percent carbon monoxide that is applicable for the
enriching gas used in fractional form.
FOR EXAMPLE:
Natural Gas = 20.0 % CO, then setting is 0.200
Propane Gas = 23.0 % CO, setting is 0.230
INPUT ALGORITHM 1 BIAS—Does not apply to
selections: FFWRD, FFWDMU, HISEL or LOSEL.
HYDROGEN CONTENT FOR DEWPOINT is only
applicable when Dewpoint is selected. Enter a value
for the percentage of Hydrogen content that is
applicable.
