FIGURE 3
Calibration ‘0-1’ Function
The ‘0-1’ function provides enhanced accuracy when totalization encompasses a large quantity or an
extended period of time such as SCF produced in a 24 hour period.
The ‘0-1’ function should be incorporated only when both the conditions listed below are met:
1) C.F.’s 1
st
digit right of decimal is 1
2) C.F.’s 5 th digit right of decimal is not 0
Example #3
Assume a turbine has a K-Factor of 79.58 pulses per SCF and the customer product
demand is 520,000 SCF a day
C.F. = 1/79.58
= .0125659 = .12566
÷10 Note: Both conditions are met
Without the ‘0-1’ function:
Set S6 #2 ‘ON’ (
↓ Position) for ÷ 10 (moves decimal point right 1 place)
Set S2@1, S3@2, S4@5, S5@7 (.1257 rounding fourth digit)
Set S1 in ‘0’ Position (0.1257) on the IT150I P.C.B.
A usage of 520,000 SCF = 41,381,600 total pulses (520,000 x 79.58) and using the C.F. of S1-S6
the displayed quantity is 520,166 SCF ( )
rather than 520,000 for a difference of 166 SCF.
With the ‘0-1’ function:
Set S6 #3 ‘ON’ (
↓ Position) for ÷ 100 (moves decimal right 2 places)
Set S2@2, S3@5, S4@6, S5@6 (.2566)
Set S1 in ‘1’ Position (1.2566) on the IT150I P.C.B.
As stated above the 24 hr usage is 520,000 SCF. The displayed quantity is now 520,001 SCF
( ) for a difference of 1 SCF.
