Ngokuqonda izinhlobo ezihlukene, ukukhetha ingxenye efanele, nokusebenzisa amasu okufaka izintambo athuthukile, ungaqinisekisa ukuthi i-potentiometer yakho isebenza kahle kunoma yiluphi uhlelo lokusebenza. Noma ngabe usebenza kumasistimu omsindo, imishini yezimboni, noma amaphrojekthi edijithali aphambili, izintambo ezifanele ze-potentiometer ziwukhiye wokuzuza ukusebenza okungcono kakhulu.

Kulabo abafuna ukuqhubekisela phambili imiklamo yabo, ukuthola amabhodi wesekethe aphrintiwe asezingeni eliphezulu (ama-PCB) kanye nokuhlanganiswa kwe-PCB kobungcweti (i-PCBA) kubalulekile. Yonga isikhathi futhi uthole ukunemba ngezingcaphuno ze-PCB kanye ne-PCBA ezisheshayo ezivela kubakhiqizi abathembekile. Qinisekisa ukuthi amaphrojekthi akho kagesi akhiwe ngokuthembeka nangobuchwepheshe kusukela ekuqaleni.
