(2) Ua pau ka paleʻana o ka waiwai solenoid voive. Hiki ke laweʻia ka'ōnaehana solenoid a kauʻia me kahi multimeter. Inā weheʻia ka carcuit, e wela ka col batonoid.
ʻO nā kumu e pili ana i ka coip coip, maikaʻiʻole a me nā lekiō maikaʻi a me ka magnetic flux leakage, e hopena ana i ka nui o nā mea i kēia manawa a puhiʻia. ʻO ke kumukūʻai solenoid he kumukūʻai, no laila he mea pono ia e pale i ka wai o ka wai mai ke komoʻana i ka valenad solenoid. Kili ka mea paʻakikī loa, inā he nui ka pū, ua nui ka nui o ka Cook, kahi i lawa ka nui o ka colo.
