Quick Program RT‐15 Parameters
With the cover removed and outside of a hazardous area, use the MODE/DN button to select the display
to program. Press and hold the ENT button. The display first shows a “P” in the lower left‐hand corner
and then displays the first program variable. The RT‐15 prompts for an entry.
When entering or editing numeric values or engineering units, the digit or character to enter or edit
blinks starting with left‐most position. Use the UP or DN button to increase or decrease a value, or
change a character. Use the SEL button to move the blinking cursor to the next digit or character. After
you have entered the entire value, use the ENT button to store it and advance to the next program
variable.
Use the SEL button to select LIMIT and ANALOG OUT assignments. Use the ENT button to store the
assignment and advance to the next program variable. The ENT button exits programming after you
have programmed the last variable.
KFR
Scaling for display of rate in specific engineering units. Determines display decimal resolution.
Initial value = 100.00 (Hz. w/2 decimals); KFR= T‐base SCALING FACTOR/K‐FACTOR where T‐base
SCALING FACTOR =
 100 for engineering units per second
 6000 for engineering units per minute
 360000 for engineering units per hour
 8640000 for engineering units per day
where K‐FACTOR is the average number of pulses/engineering unit of the transducer.
Round result to desired decimal accuracy and enter KFR using only that number of decimal places. Use
no more than four digits regardless of decimal position! Maximum is 65535 with the decimal in any
location.
GATE AB
Gate time, .01 to 600 seconds. Display and analog output update time interval. Initial value is 002.00
seconds.
SAMPLE A & B
Digital filter on RATE PL, 0 to 253 (0 min., 253 max.) affecting the update of the display and analog
output. Initial value is 010.
ENG UNITS
The desired engineering units for display of rate are programmable using up to four letters. Example:
