will appear:
Using the

indication.
Choices are:

The existing totalizer values are automatically converted into the
selected unit of measure.
After selecting unit of measure for flow rate, press Enter. You will see
the following screen for selecting unit of measure for the totalizer.
Choices are as follow; any existing values on the totalizers will
automatically be converted into the new selected unit of measure

After the totalizer unit of measure selection, press the E key the
following screen will appear:
FULL SCALE (MAXIMUM FLOW)
If you changed the unit of measure, the full scale or maximum flow
may also need to be changed to reflect the maximum flow rate with
the new unit of measure. This is a very important parameter as it
relates to other parameters including frequency output, low-
flow cut-off, alarm outputs and analog signal outputs. Adjust
the desired new full scale setting based on your meter size and your
applications requirements, making sure that it falls within the sug-
gested flow range of the meter.
When done, press enter and then the
will appear.
This is the same full scale parameter as previously visited. It is
positioned here to provide ability to change full scale setting if no unit
of measure change is necessary.
The full scale can be chosen in a range of 0.4 up to 39.4 ft/sec. A flow
value is assigned to the analog output as well as the frequency output
by the full scale scaling. The scaling is valid for both flow directions.
NOTE: If the flow rate is exceeding the full scale setting by more
than 5%, an error is indicated that the selected full scale range
is exceeded. (Terminals 7 and 8)
Once this is done, press E and then the
will appear:

LOW FLOW CUTOFF

This is the low flow cutoff function. It is used to assign a low flow rate
at which measurement will stop, preventing measurement and thus
totalization errors. This parameter can be programmed from 0 % up
to 10% of selected full scale flow rate.
Place the > arrow next to "change" and then press the
following screen will appear:
The factory setting is 0.2%. Increasing this value will help prevent
false readings during "no flow" conditions due to fluid movement in
the pipe caused by vibrations or piping arrangements.
Using the
and
keys select a value and then press ENTER.
