Indlela yokuhlola yokusebenza kwephampu yamafutha
Amanye amaphutha aqinile (njengokungasebenzi, njll.) wephampu kaphethiloli wemoto kulula ukuwahlulela, kodwa amanye amaphutha athambile aphakathi nendawo kunzima kakhulu ukuwahlulela.Kulokhu, ukusebenza kwephampu kaphethiloli kungahlulelwa ngendlela yokuthola ukusebenza kwamanje kwephampu yamafutha nge-multimeter yemoto yedijithali.Indlela eqondile imi kanje.
(1) Faka i-multimeter yemoto yedijithali kubhulokhi yamanje, cindezela ukhiye wokusebenza (KHETHA) ukuze ulungise ibhulokhi yamanje eqondile (DC), bese uxhuma amapeni okuhlola amabili ngochungechunge emugqeni wokuxhuma wephampu kaphethiloli ukuze ube. ihlolwe.
(2) Qala injini, lapho iphampu yamafutha isebenza, cindezela ukhiye wokurekhoda oguqukayo (MAX/MIN) we-multimeter yemoto yedijithali ukuze urekhode ngokuzenzakalelayo umthamo omkhulu kanye nobuncane bamanje lapho iphampu yamafutha isebenza.Ngokuqhathanisa idatha etholiwe nevelu evamile, imbangela yokwehluleka inganqunywa.
Izinyathelo Zokuphepha Zokuthola Ukwehluleka Kwephampu Yamafutha Hlela Ukusakaza
1. Iphampu yamafutha endala
Lapho kuxazululwa izinkinga zamaphampu kaphethiloli ezimotweni esezisetshenziswe isikhathi eside, lawa maphampu kaphethiloli akufanele ahlolwe omile.Ngoba lapho ipompo likaphethiloli lisuswa, kukhona uphethiloli osele endaweni yephampu.Ngesikhathi sokuhlolwa kwamandla okusebenza, uma ibhulashi kanye nesihambisi bengaxhumene kahle, inhlansi izothungela uphethiloli kukesi yepompo futhi ibangele ukuqhuma.Imiphumela emibi kakhulu.
2. Iphampu yamafutha entsha
Iphampu kaphethiloli esanda kushintshwa ngeke ihlolwe yomile.Ngenxa yokuthi injini yepompo likaphethiloli ivalwe esikhwameni sepompo, ukushisa okukhiqizwe amandla okukhanyisa ngesikhathi sokuhlolwa okomile akukwazi ukuchithwa.Uma i-armature isishise ngokweqile, injini izoshiswa, ngakho-ke iphampu yamafutha kufanele icwiliswe kuphethiloli ukuze kuhlolwe.
3. Ezinye izici
Ngemva kokuthi iphampu kaphethiloli ishiya ithangi likaphethiloli, iphampu kaphethiloli kufanele isulwe ngesikhathi, futhi izinhlansi kufanele zigwenywe eduze kwayo, futhi isimiso sokuphepha sokuthi "intambo kuqala, bese kuvula amandla" kufanele kulandelwe.
