7.2.1.2.1 Data Type
The 4-bit Data Type field determines the type of data of the specific sensor.
7.2.1.2.2 Factory Calibrate
Factory calibration is available for the process inputs. Clearing this bit will disable the factory
calibration values.
7.2.1.2.3 Writeable
The writeable bit is cleared, indicating that the sensor values may not be overwritten.

7.2.1.3.2 Lock
If set, the user-specified units of measure string (4 character maximum) will be used in place of
the default units of measure.
7.2.1.3.3 Apply Scaling
If set, the user-defined Offset and Gain values will be used to adjust the sensor reading:
Result = (Raw Reading * Gain) + Offset
7.2.1.3.4 Assigned
The Assigned bit will always read as 0.
7.2.1.3.5 Available
The Available bit will always read as 0.
