When entering or editing the KFR value, the leftmost digit will blink (cursor). Select the digit to
edit using the SEL button or magnetic switch. The cursor will move to the right and will wrap
around. The decimal point can be relocated when it is selected (blinking). Use the UP or DN
button or magnetic switch to increment or decrement the variable value or move the decimal
point. Use DN to move the decimal point to the right, UP to move it to the left. When the
desired value is displayed, use the ENT button or magnetic switch to store the programmed value
and advance to the next variable.
GATE A B – Gate time. This variable sets the sample time on the incoming frequency for the
RATE A
GT (Gate Time) displays. This variable is programmed in tenths of a second and the
allowable range is from .01 to 600 seconds. This variable affects the update of the display and
analog output and is useful in stabilizing the display and output when dealing with slight
variations in flow. Do not set GATE TIME to zero as it will disable rate display.
When entering or editing the value, the digit being edited will blink starting with left-most digit.
Select the digit to edit using the SEL button or magnetic switch. Use the UP or DN button or
magnetic switch to increment or decrement the variable value. When the desired value is
displayed, use the ENT button or magnetic switch to store the programmed value and advance to
the next variable.
Initial default is 002.00 seconds
SAMPLE A - This variable determines the amount of digital filtering performed on the
incoming frequency for the RATE A
PL (Pulse Length) display. The allowable range is from 0 to
253 with 0 providing the least level of filtering and 253 the maximum. This variable affects the
update of the display and analog output and is used as a filter to stabilize the display and output.
Initial default is 010
When entering or editing the value, the digit being edited will blink starting with left-most digit.
Select the digit to edit using the SEL button or magnetic switch. Use the UP or DN button or
magnetic switch to increment or decrement the variable value. When the desired value is
displayed, use the ENT button or magnetic switch to store the programmed value and advance to
the next variable.
ENG UNITS A - The desired engineering units for display of rate are programmable using up to
four letters. Example: GPM_
Initial default is HZ__
NOTE: The engineering units display does not affect the scaling in any way and serves as
nothing more than a label. The rate scaling is performed in the KFR calculation.
The first (left-most) character will be highlighted with the blinking cursor first. The SEL button
or magnetic switch moves the cursor and the UP or DN button or magnetic switch scrolls
through the alphabet. When the characters are all entered, use the ENT button or magnetic switch
to store the variable. The RT-Ex15 will exit the variable programming mode and return to the
selected display.
