Operation and Programming Manual
20
When entering or editing the value, the digit you are editing blinks, starting with left‐most digit. Use the
SEL button (or magnetic switch) to select the digit to edit. Use the UP or DN button (or magnetic switch)
to increase or decrease the variable value. When the desired value displays, use the ENT button (or
magnetic switch) to store the 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 you are editing blinks, starting with left‐most digit. Use the
SEL button (or magnetic switch) to select the digit to edit. Use the UP or DN button (or magnetic switch)
to increase or decrease the variable value. When the desired value displays, use the ENT button (or
magnetic switch) to store the 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__
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. Use the SEL button (or
magnetic switch) to move the cursor; use the UP or DN button (or magnetic switch) to scroll through the
alphabet. After you have entered the characters, use the ENT button (or magnetic switch) to store the
variable. The RT‐15 then exits the variable programming mode and returns to the selected display.
TOTAL Display Modes
The RT‐15 displays the JOB or GRAND total based on the programmed KFT, engineering unit, and
decimal location. There are two TOTAL displays: TOTAL A (Job Total) and GRAND TOTAL A. The GRAND
total is a second totalizer with a secured reset. The RT‐15 retains both totals when the power is
removed. The totals retained at power‐down are updated once every 25 seconds. Due to this update
interval, the totals retained may not include previous flow for up to 25 seconds if flow was present when
the power was removed.
