ENG UNITS A or B
The desired engineering units for display of rate are programmable using up to four letters. Example:
GPM_
Default is: HZ__
The left-most character is highlighted with the blinking cursor first. The SEL key moves the cursor; use
the UP and DN keys to scroll through the alphabet. After you have entered all characters, press the ENT
key to store the variable.
Total Mode Programming
Program the Total parameters from the TOTAL A or TOTAL B display screen. Use the MODE key UP to
select the TOTAL A or TOTAL B display. Press and hold the ENT key until KFT appears.
TOTAL A or B

KFT A or B VALUE

ENG UNITS A or B
When entering or editing the value, the digit blinks starting with the left-most digit. Select the digit to
edit using the SEL key. Press and hold the UP or DN key to increase or decrease the value. When the
desired value displays, press ENT to store and advance to the next variable.
KFT A or B VALUE
The KFT is a scaling factor to display totals in a engineering unit such as Gallons. The KFT value also
determines the decimal resolution of the total display. The KFT is calculated using the K-factor of the
transducer being monitored. The K-factor is the number of impulses per engineering unit established by
the transducer manufacturer or by a calibration test.
You can obtain the KFR from the calibration data sheet supplied with the flow meter. You can also
calculate the KFR using the formula below:
Default is: 10000. (total pulses with no decimals)
To calculate the KFT factor, use the following formula:
KFT= 10000/K-FACTOR
Where:

10000 is a constant
