Depi li se prèske enposib ki mezire vòltaj la nan pòtay lavil la nan sous la (VGS) nan yon Fet, ou ka mezire vòltaj la ki prezan nan tout R3, paske li se menm bagay la kòm VGS. Ajiste valè R3 a kòmsadwa, si vòltaj la se pa nan seri a nan 0.8-1.2 vòlt.

Since it is almost impossible to measure the voltage from the gate to the source (VGS) of a FET, you can measure the voltage that is present across R3, because it is the same as VGS. Adjust R3′s value accordingly, if the voltage is not within the range of 0.8-1.2 volts.
