5.1.7.1 Sensor Trigger Function
The Sensor Trigger function is used to reset the IPSO min/max values as well as controlling the Calibration
process.

Start
Setting the Reset Min/Max bit to 1 will reset the Min/Max values recorded by the IPSO process.
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 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 Offset value.
5.2 Thermocouple Descriptor
The Thermocouple Input interface provides interfaces to type J, K, T, E, N, R, S, B, and C thermocouples. The default T type is
typically used on Heat Flux sensor devices (HFS-05). The Sensor Configuration and Sensor Device fields may be written to
provide control of the overall function of the channel and the thermocouple types used.
