    PSoC5LP Finger threshold and noise level for CapSense tuning




      We are currently doing CapSense tuning for PSoC 5 LP.

      The following phenomenon occurred while tuning.





      The above screen is in the initial state.
      A high noise level is displayed.


      Just changing the finger threshold(FT) from 190 to 180 lowers the noise level as shown in the screen below.


      We can't understand that the noise level changes just by changing the finger threshold(FT).


      This phenomenon happens occasionally but do you understand why?
      Or is there any way to deal with it?
