Incazelo Yomkhiqizo

Ukwengeza, ifaka isekethe yokuvikela ukugcwala kakhulu evikela ithuluzi ekulimaleni okungaba khona ngenxa ye-voltage eyeqile noma yamanje. Lokhu kuyenza ibe yithuluzi elihle kakhulu futhi elihlala isikhathi eside ezinhlobonhlobo zezinhlelo zokusebenza. Esinye sezici eziyinhloko zalokhui-multimeterukuguquguquka kwayo. Ingasetshenziswa ukukala i-DC kanye ne-AC voltage, ikuvumela ukuthi uhlole kalula amasekhethi nezingxenye.

Ukwengeza, ingakala i-DC yamanje, ikunike ulwazi olubalulekile mayelana nokugeleza kwamanje. Isilinganiso sokumelana ngomunye umsebenzi wale multimeter. Ikuvumela ukuthi unqume ngokunembile ukumelana nezingxenye ezihlukahlukene, ikusize uxazulule izinkinga futhi ubone izingxenye ezinephutha. Ukwengeza, i-multimeter ingasetshenziswa ukuhlola ama-diode nama-transistors, okukuvumela ukuthi uqinisekise ukusebenza kwawo. Iphinde inikeze amandla okulinganisa izinga lokushisa, okukwenza ukwazi ukuqapha izinguquko zezinga lokushisa kumasistimu ahlukene. Ngokungeziwe kule misebenzi, i-multimeter futhi inomsebenzi wokuhlola ukuqhubeka kwe-inthanethi. Ungayisebenzisa ukuze uhlole ukuthi isifunda siphelile noma kukhona yini ukuphuka noma ukuphazamiseka kusekethe.

Lokhu kubaluleke kakhulu uma uxilonga amaphutha noma uqinisekisa ubuqotho bokuxhunywa kukagesi. Sekukonke, lokhu kubanjwe ngesandla 3 1/2i-multimeter yedijithaliithuluzi lekhwalithi ephezulu elihlanganisa ukuzinza, ukwethembeka, nokuqina. Amakhono ayo okulinganisa anhlobonhlobo, kusukela ku-voltage kanye namanje kuye ukumelana nezinga lokushisa, kuyenza ibe ithuluzi elibaluleke kakhulu kochwepheshe nezimfundamakhwela ngokufanayo. Ngesixhumi esibonakalayo esisebenziseka kalula kanye nosayizi ohlangene, iyithuluzi eliphathwa ngesandla nelilungele izinhlelo zokusebenza ezahlukene zikagesi neze-elekthronikhi.
