Pressure Transfer function:
Select the pressure transfer
function for calculated output:
Linear: (output scaled linearly
per configured range) Square
Root: (output scaled as square
root conversion per
configured range – for flow
measurements)

Low Flow Cutoff Mode:
For Square Root (Transfer
function) configurations only,
choose the operating mode to
determine the low flow cutoff
breakpoint: Dual slope:
(breakpoint determined by dual
slope calculation) User
configuration: (breakpoint
defined by user)
Zero Flow: Sets analog output
to 4mA when square root /
flow is below user defined
flow cutoff value.
Note: Sets loop output to low
saturation when the differential
pressure is below
–10%Flow.

SP Zero Correct
[24SPZRO]
Corrects the static pressure to a
zero value psi for DP transmitters
only
Performs the correction of
measured static pressure value
to a value of zero psi.
Executing this selection
corrects Static Pressure Zero
based on the input static
pressure.
The live value of the static
pressure input is shown on this
display so the user can
easily see the result of the
correction.
