INP
View or change the lter (set F), jitter (set J), enable REED
mode (50Hz maximum pulse input) and enable BURST
mode. Use the lter setting if the display is jumping
excessively due to ow conditions. Use the jitter setting to
enter a time delay to handle start up conditions. Jitter units
are seconds. Turn the BURST mode on if the input pulses
to the FT unit are not delivered steadily across time but
are delivered in groups or 'bursts' of pulses separated by
moments of inactivity.
PCODE
Enter the pass code for access to protected features.

The FT440 has two available alarm outputs while the FT430
and FT450 only have one. The P/A tab changes the function
of the scaled pulse outputs. Default is scaled pulse. Any
scaled pulse output can be changed to alarm high or alarm
low. If alarm options are selected menu tabs for setting the
alarms will be displayed on the main menu (alarm 1) or the
secondary menu (alarm 2) If the alarm options are selected
a Set H (hysteresis) tab is available. The hysteresis entry is
a % value. The value denes the % change required for a
change in alarm state to occur.
The factory setting will show Set P2 (FT440 only) which
allows one to view or change the volume of ow totalized
per pulse sent to pulse out 2. The units for Set P2 follow
the units selected for the rate display. If P2 is selected
as an alarm the menus will change to Set A2 and a Set
H (hysteresis) tab is available. The hysteresis entry is a
% value. The value denes the % change required for a
change in alarm state to occur.
Set 4 (FT440 only) input the ow rate at which 4 mA (min)
output is desired.
ADJ L (FT440 only) allows the adjustment of the 4 mA and
20 mA values so that one can tune performance of the
FT440 to match the installed system values. The adjustment
units range from 0-32. Positive values adjust the setting
incrementally larger and negative values adjust the setting
incrementally lower.
