Heat Flux Sensor Parameters
The SP-016 provides 3 sensor parameters related to the Heat Flux Sensor (Sensor 0). These values may be updated
based on the specific heat flux sensor being used.

Heat Flux User Calibration Parameters
The SP-016 provides a single User Calibration register that may be set while the device is in the User Calibrate mode
and is ‘added’ to the calculated value during normal operation, providing a fixed offset to the calculated Heat Flux
value. During the User Calibration process, the actual (independently measured) Heat Flux value (Target Value) may be
entered and the SP-016 will save the difference between the current measured value and the Target Value as the
Calibration value. The User Calibration may be used when the sensor is measuring 0 heat flux to provide a simple
method to correct for minor offset errors.
Note:
The device must be put into the ‘Calibration’ mode to access the User Calibration parameters.
