L_TYPE is direct
When the desired output is the measured variable, set the XD_SCALE to the Primary_Value_Range. This
is found in the Sensor Transducer Block. Set OUT_SCALE to match XD_SCALE.
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 sensor measurement and the relationship
between the inferred measurement and sensor measurement is square root, set the XD_SCALE to
represent the operating range 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:

Note
When the engineering units of the XD_SCALE are selected, this causes the engineering units of the
PRIMARY_VALUE_RANGE in the Transducer Block to change to the same units. This is the only way to
change the engineering units in the sensor transducer block, PRIMARY_VALUE_RANGE parameter.
