C.F. = Calibration Factor as entered in S1-S5 (S5 is the most significant digit)
EXAMPLE #2: F = 500 Hz C.F. = 250

Change of Calibration Engineering Units
Assume that liters rather than gallons are the desired engineering unit.
Example # 3: K-Factor = 250 pulses per gallon
Liters = 3.785 per gallon
C.F. =
Pulses per Gallon
Units per Gallon
C.F. = 250/3.875
C.F. = 66 Pulses per liter
On the Factoring P.C.B.:
Set S1@6, S2@6, S3@0, S4@0, S5@0
Example #4: The Engineering Unit is pounds in 10
th
s CO
2
K-Factor = 250 pulses per gallon
Pounds of CO
2
= 8.470 per gallon
In order to establish 10
th
s, increase lbs./gal. by a factor of 10
C.F. = 250/84.7
C.F. = 3
