Thanks Mr.Nelson Pass !!
Should I use two 200k trim pot ?
It is because in a China Diy web, someone have tried to use 100K X2.
Inaddition, he also said that it no different with the offset (15mV) after took both of it out !
I am indoubt what he said, even in A30 manual , the std. offset is <100mV.
Someone said the R1 & R8 must be same value.
