I-voltage tester iyithuluzi elibalulekile ekunakekeleni nasekuhlolweni kukagesi. Ukusetshenziswa ngendlela efanele akugcini nje ukuthuthukisa ukusebenza kahle komsebenzi kodwa futhi kuqinisekisa ukuphepha kokusebenza. Ukwenza kahle lezi zindlela ezisebenzayo kungasiza ochwepheshe benze izilinganiso ngokunemba okukhulu.
Okokuqala, ukukhetha ububanzi obufanele kubalulekile. Ngaphambi kokulinganisa, linganisa ububanzi be-voltage okufanele ikalwe bese ukhetha ububanzi obulingana ne-voltage. Uma ungaqiniseki nge-voltage, kunconywa ukuthi uqale ebangeni eliphakeme kakhulu bese wehlisa kancane ibanga ukuze ugweme ukulimala kumitha noma ukufundwa okungalungile ngenxa yobubanzi obuncane. Isibonelo, uma ukala amandla endlu angu-220V AC, khetha i-AC 750V noma ibanga eliphezulu.
Okwesibili, naka indlela yokuxhumana efanele yophenyo lokuhlola. Kumasekhethi aphezulu-ama-impedance, afana namasekhethi edijithali noma izilinganiso zesignali ezibuthakathaka, i-metal probe ye-test probe kufanele ithinte kancane indawo yokuhlola ukuze igweme ukungenisa ukuphazamiseka okukhulu ngenxa yengcindezi eyeqile. Futhi, qinisekisa ukuthintana okugcwele phakathi kwe-test probe kanye ne-conductor. Uma kunesidingo, sebenzisa iziqeshana zengwenya ukuze uvikele uphenyo ukuze uvimbele ukuxega nokuguquguquka kokufundwayo.
Izinyathelo zokuphepha zibaluleke kakhulu uma kulinganiswa ama-voltage aphezulu. Ngaso sonke isikhathi sebenzisa kahle-imikhondo yokuhlola evalekile, gcina izandla zakho zomile, futhi ugweme ukuthinta amakhondaktha ngamakhono ahlukene ngesikhathi esisodwa. Abanye abahloli bamandla kagesi aphezulu-banomsebenzi wokuzikhipha ozenzakalelayo, okhipha ngokushesha ishaja eyinsalela ngemva kokulinganisa ama-capacitor noma{4}}amadivayisi anamandla kagesi aphezulu, okunciphisa ingozi yokushaqeka kukagesi.
Ngaphezu kwalokho, ukulinganisa okuvamile kuqinisekisa ukunemba kokulinganisa. Abahloli bamandla kagesi abasebenzisa{1}}isikhathi eside bangase babe ne-zero{2}}point drift noma ukuncipha kokuzwela. Kunconywa ukuthi zilinganiswe ngonyaka ngochwepheshe, noma ukuziqhathanisa nokuzilungisa kusetshenziswa umthombo ojwayelekile endaweni yaselabhorethri.
Okokugcina, isitoreji esifanele singaphinda sandise impilo yedivayisi. Gwema ukuveza umhloli kumazinga okushisa aphezulu, umswakama, noma ukuphazamiseka okunamandla kazibuthe kagesi isikhathi eside. Khipha ibhethri uma ingasetshenziswa ukuvikela ukuvuza nokugqwala kwesekhethi. Ukwenza kahle lawa macebiso kuzokwandisa ukusebenza kwesihloli sakho se-voltage ngenkathi uqinisekisa ukuphepha komsebenzisi.
