Indirect Square Root
Indirect Square Root signal conversion takes the square root of the value computed with
the indirect signal conversion and scales it to the range and units of the PV and OUT
parameters..
When the converted input value is below the limit specified by the LOW_CUT parameter,
and the Low Cutoff I/O option (IO_OPTS) is enabled (True), a value of zero is used for the
converted value (PV). This option is useful to eliminate false readings when the differential
pressure measurement is close to zero, and it may also be useful with zero-based
measurement devices such as flowmeters.
Note
Low Cutoff
is the only I/O option supported by the AI block. You can set the I/O option in
Manual
or
Out of Service
mode only.
