Isikhangeli sobunwele sisixhobo esibalulekileyo kushishino lwempahla olulukiweyo, esisetyenziselwa ukuchonga naziphi na iinwele ezithe tyaba ezikhoyo kumsonto ngelixa zibaleka ngesantya esiphezulu. Esi sixhobo saziwa ngokuba sisixhobo sokujonga ubunwele kwaye sisixhobo esibalulekileyo esixhasa umatshini wokulwa. Owona msebenzi wayo kukumisa umatshini wokulwa ngokukhawuleza nje ukuba kubhaqwe nawuphi na umsonto we-fuzz.

Umtshini weenwele uquka izinto ezimbini eziphambili: ibhokisi yokulawula umbane kunye ne-bracket probe. Iprobe ye-infrared ifakwe kwi-bracket, kwaye umaleko wesanti uhamba ngesantya esiphezulu kufuphi nomphezulu we-bracket. Iprobe yenzelwe ukubona uboya, kwaye xa isenza njalo, ithumela umqondiso kwibhokisi yokulawula yombane. Inkqubo yangaphakathi ye-microcomputer ihlalutya imilo yoboya, kwaye ukuba idibana nomgangatho ochazwe ngumsebenzisi, umqondiso wemveliso ubangela ukuba umatshini wokulwa uyeke.

Isikhangeli sobunwele sidlala indima ebalulekileyo ekuqinisekiseni umgangatho womsonto oveliswayo. Ngaphandle kwayo, iinwele ezikhululekileyo kumsonto zinokubangela imiba eyahlukeneyo njengokuqhekeka komsonto, iziphene zelaphu, kwaye ekugqibeleni, ukunganeliseki kwabathengi. Ke ngoko, kubalulekile ukuba nesixhobo esithembekileyo sokujonga iinwele endaweni yokunciphisa ukwenzeka kwezi ngxaki kunye nokugcina umgangatho wemveliso yokugqibela.

Ukuqukumbela, isixhobo sokujonga ubunwele sisixhobo esibalulekileyo kushishino lwempahla olulukiweyo, sinceda ekuqinisekiseni ukuba umsonto ovelisiweyo ukumgangatho ophezulu. Ngokukwazi ukubona kunye nokumisa umatshini wokulwa ngokukhawuleza, esi sixhobo sinokunciphisa kakhulu ukwenzeka kweziphene zelaphu kunye nezikhalazo zabathengi.
