T UNIT
View or change the total volume units
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 ow 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 ow 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

RESET
Reset the total ow 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.
