specialized functions for

heat flow measurement

  Easy scaling settings：directly enter the sensitivity of the heat flow sensor

  Calculations：waveform processing function for the analysis of temperature and heat flow

  (Simpleaverage, moving average, integration, heat transmission coefficient), Integration with numerical

  calculations
