The Calibration mode is entered by writing a 1 to the Calibration Mode bit. While in the calibration
mode the calibration registers may be accessed, the Capture High/Low may be used to capture real-
time values and the Calibration Start may be set.
When the Calibration Start bit is set the Calibration Status bit will remain set until the calibration
process is complete.
Setting the Calibration Reset bit will clear the calculated Gain and Offset values.
6.2.4.1
Max Range
The SP-006 allows pressures of 150% of the full range value.
6.3
Temperature Sensor
The SP-006 provides a discrete temperature sensor interface.
6.3.1
Temperature Descriptor
The SP-006 configures the sensors based on the factory device list and user-specified list index. The Sensor
Configuration and Sensor Device fields may be written to provide control of the overall function of the
channel and the signal types used.

6.3.1.2.1
Data Type
The 4-bit Data Type field determines the type of data of the specific sensor.
6.3.1.2.2
Factory Calibrate
Factory calibration is available for the SP-006 process inputs. Clearing this bit will disable
the factory calibration values.
6.3.1.2.3
Writeable
The writeable bit is cleared, indicating that the sensor values may not be overwritten.
