CHANNEL
Select the channel that corresponds to the desired sensor measurement. The transmitter
measures both pressure (channel 1) and sensor temperature (channel 2).

Note
Channels 12-13 are only available when you order the Advanced Diagnostic Block is
licensed.
L_TYPE
The L_TYPE parameter defines the relationship of the sensor measurement (pressure or
sensor temperature) to the desired output of the AI Block (e.g. pressure, level, flow, etc.).
The relationship can be direct, indirect, or indirect square root.
Direct
Select direct when the desired output will be the same as the sensor measurement
(pressure or sensor temperature).
Indirect
Select indirect when the desired output is a calculated measurement based on the sensor
measurement (e.g. a pressure measurement is made to determine level in a tank). The
relationship between the sensor measurement and the calculated measurement will be
linear.
Indirect square root
Select indirect square root when the desired output is an inferred measurement based on
the sensor measurement and the relationship between the sensor measurement and the
inferred measurement is square root (e.g. flow).
XD_SCALE and OUT_SCALE
The XD_SCALE and OUT_SCALE each include three parameters: 0%, 100%, and
engineering units. Set these based on the L_TYPE:
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.
