The output mode is used to select the
proportional mode (proportional to input
differential pressure) or square root ex-
traction mode (proportinal to
fl
ow rate)
for output signal (4 to 20mA).
In case of square root extraction mode,
the cut point and the mode below the cut
point can be set.
Under display 2 , press <INC> or <DEC>
for selection of the square root extraction
mode or proportional mode.

Since display 7 is presented when the
square root extraction mode is selected,
the low
fl
ow cut point should be set.
Cut point is adjustable within the range
of 0.00 to 20.00%. The cut point is used
for stabilizing output near 0% when the
square root extraction mode is selected
for output signal.
There are two modes; in one mode,
proportional output is selected for output
below a cut point (Fig. A) and in the other
mode, out put is forcibly reduced to 0%
for output below a cut point (Fig. B).
Under display 13 , linear or zero output
is selectable for output below the cut
point.
