When an inferred measurement is made based on the sensor
measurement, set the XD_SCALE to represent the operating range that
the sensor will see in the process. Determine the inferred measurement
values that correspond to the XD_SCALE 0 and 100% points and set these
for the OUT_SCALE.
When an inferred measurement is made based on the transmitter
measurement and the relationship between the inferred measurement
and sensor measurement is square root, set the XD_SCALE to represent
the operating range that the sensor will see in the process. Determine the
inferred measurement values that correspond to the XD_SCALE 0 and
100% points and set these for the OUT_SCALE.

The block output (OUT) may be set manually.
OUT reflects the analog input measurement or the simulated value
when simulation is enabled.
The block is not processed. FIELD_VAL and PV are not updated and
the OUT status is set to Bad: Out of Service. The BLOCK_ERR
parameter shows Out of Service. In this mode, you can make
