SET D
View or change the number of decimals displayed in the
total volume display
SET P OR SET A
The factory setting will show Set P which allows one to
view or change the volume of flow totalized per pulse sent
to pulse out 1. The units for Set P follow the units selected
for the rate display.
(With EXIT highlighted, pressing the up
arrow four times will access the secondary menu. The P/A
tab in the secondary menu will allow pulse out 1 to be an
alarm. The alarm can be set to trigger on either a high or
low flow condition as determined by the user.)
SET P
Because the scaled pulse output is set by the user, be
certain to choose a Set P value that provides reasonable
resolution while not exceeding the maximum allowable
input frequency of the receiving device or the 6.8 Hz
maximum output frequency of the FT unit.
K-factor: Remember that Set P is expressed in units totaled
per output pulse (G/P if using gallons) while K-factors are
expressed in pulses per gallon (P/G). To determine K-factor
from Set P, divide 1 by Set P (if Set P is expressed in gallons).
Conversely, 1 divided by K-factor equals Set P.

Note: The blacked-out values are beyond the 6.8 Hz maximum
output frequency and will not properly output a scaled pulse. The
minimum Set P value can be calculated as follows:
Max Flow Rate (
in units per second
) / 6.8 Hz = Minimum Set P
SET 20 (FT440 ONLY)
Input the flow rate at which 20 mA (max) output is desired
RESET
Reset the total flow volume to zero. This tab is not available
when the -64 non resettable total option is ordered
EXIT
Return to the home screen, enter a submenu, or accept a
parameter change
The Exit menu also allows access to the secondary menu,
as described on the next page.
