Since the Rate Scaling and optional Analog Scaling variables are based on the K‐factor, it is best to start
by programming the K‐factor.
Total Mode Programming
K‐Factor in Pulses per Engineering Unit
You will use the Total Display Mode to enter this scaling factor, which is used to display both Rate and
Total in an engineering unit such as gallons, ounces, liters or cc’s. The K‐factor is the number of impulses
per engineering unit established by the transducer manufacturer or by a calibration test. An average K‐
factor is provided for several basic engineering units with each meter on the flow meter calibration
sheets.
Initial default K‐factor is 1.00000 (default displays are: total in pulses and rate in Hz.)
Enter the average K‐factor in pulses per desired unit of display directly as it is given on the calibration
sheet (up to six digits with a decimal point). You can enter the K‐factor with either leading or trailing
zeroes.
Use the DN/MODE button or magnetic switch to view the Total Display Mode. Press and hold the ENT
button or activate and maintain the ENT magnetic switch for three seconds until the display indicates
the RT‐10x model number.
The display then briefly indicates “PPen U” (pulses per engineering unit) followed by the K‐factor.
When editing the K‐factor, the leftmost digit will blink (cursor). Use SEL to move the cursor to the right.
The cursor will wrap around. Use UP/DN to increment or decrement numerals. Edit the decimal point
last. Use DN to move the decimal point to the right, UP to move it to the left. When the desired value
displays, use ENT to store it and exit K‐factor programming. See the flowchart below.
