Remove the insignificant decimals often produced with this calculation as they result in displays with a
misleading level of precision far exceeding the accuracy of the meter. Use a maximum of four digits
regardless of decimal point position! Enter KFR without regard to the location of the decimal point in the
display. Enter the desired decimal location in the next procedure. The largest acceptable number for
KFR is 65535.
For example:
A flowmeter has a K-factor 2053.7 imp/Gal and the display should read in Gal/Min.
KFR = 6000/2053.57 = 2.921741 for GPM
292174 is > 65535! 29217 > 4 digits! 2922 is best! Enter 2922 for KFR. For this example,
KFR=2.922, the decimal point is set to three decimal places in the next procedure.
Set Decimal Point
Press and hold UP or DN to increase or decrease the value. To increase the increment or decrement
rate, while holding the UP or DN key, press and hold SEL for medium rate or ENT for maximum rate.
When the desired value is displayed, press ENT to store the programmed value and advance to the next
variable.
Always release the SEL or ENT key before releasing the UP or DN key or the LLC-BA will proceed to next
variable leaving the last variable with an unpredictable value.
Decimal Point for KFR
This variable selects the location of the decimal point in the KFR factor and the display. This display is
always zeros with a decimal point.
00000.00 (factory default)
Use the UP or DN key to move the decimal point left or right. Press ENT to store and advance to the next
variable.
Engineering Units KFR
Enter the engineering units for display of rate with up to three characters or letters. Example: gpm
hz_ (factory default)
Program or edit the left-most character first. Press UP or DN until it appears. Then press SEL to store.
Repeat the procedure for the second character. Repeat for the 3rd character but store with the ENT key.
The next variable will display.
