Hi hmani,

 

 

          I have assigned HX=2,HY=3,and HZ=4 then the register reading is

 

 

Register                                                    Values
HXVHD0.071
HYVHD0.467
HZVHD

0.046

VTHD                                                                                     6.584

 

according to this formula THD = sqrt(HXVHD^2+HYVHD^2+HZVHD^2)

 

(0.071^2+0.467^2+0.046+2)=0.4746 but is value is not related to my VTHD register (6.584)

 

 

pls tell me what is the reason i am not getting related out put?
