L_TYPE is Indirect
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.
L_TYPE is Indirect Square Root
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.
Engineering Units
NOTE!
To avoid configuration errors, only select Engineering Units for XD_SCALE
and OUT_SCALE that are supported by the device (see "Supported Units" on
page C-27.
The Rosemount 5900S is supplied with six pre-configured AI blocks
according to Table 4-6. The block configuration can be changed if needed.
