Sisitemu yo gupima ingufu za elegitoronike ningirakamaro mubikorwa hafi ya byose, ubucuruzi nubucuruzi.Kubera ko selile yimikorere aribintu byingenzi bigize sisitemu yo gupima imbaraga, bigomba kuba byukuri kandi bigakora neza igihe cyose.Byaba nkibice byateganijwe kubungabunga cyangwa gusubiza imikorere yabuze, uzi kugerageza aumutwaroirashobora gufasha gufata ibyemezo byuzuye bijyanye no gusana cyangwa gusimbuza ibice.
Kuki imitwaro itwara imizigo?
Uturemangingo twikorera dukora mugupima imbaraga zashyizwemo nikimenyetso cya voltage yoherejwe nisoko ryateganijwe.Igikoresho cya sisitemu yo kugenzura, nka amplifier cyangwa ishami rishinzwe kugenzura impagarara, hanyuma ihindura ibimenyetso muburyo bworoshye-gusoma-ku gipimo cyerekana imibare.Bakeneye gukora hafi yibidukikije, bishobora rimwe na rimwe gutera ibibazo byinshi mumikorere yabo.
Izi mbogamizi zituma selile yimitwaro ikunda kunanirwa kandi, rimwe na rimwe, barashobora guhura nibibazo bigira ingaruka kumikorere yabo.Niba kunanirwa bibaye, nibyiza ko ubanza kugenzura ubusugire bwa sisitemu.Kurugero, ntibisanzwe ko umunzani uremerewe nubushobozi.Kubikora birashobora guhindura selile yumutwaro ndetse bigatera no guhungabana.Imbaraga ziyongera zirashobora kandi gusenya ingirabuzimafatizo, kimwe nubushuhe ubwo aribwo bwose cyangwa imiti yameneka yinjira mubipimo.
Ibimenyetso byizewe byo kunanirwa kwingirangingo zirimo:
Igipimo / igikoresho ntikizongera cyangwa ngo gihindurwe
Ibisomwa bidahuye cyangwa byizewe
Uburemere butagereranywa cyangwa impagarara
Gutembera bisanzwe kuri zeru
ntabwo yasomye na gato
Kuremerera ibibazo by'akagari:
Niba sisitemu yawe ikora nabi, genzura ubumuga ubwo aribwo bwose.Kuraho izindi mpamvu zigaragara zitera kunanirwa na sisitemu - insinga zahujwe zitsindagiye, insinga zidafunguye, kwishyiriraho cyangwa guhuza impagarara zerekana panne, nibindi.
Niba imitwaro ya selile yananiwe kugaragara, urukurikirane rwibibazo byo gukemura ibibazo bigomba gukorwa.
Hamwe na DMM yizewe, yujuje ubuziranenge kandi byibuze igipimo cya 4.5, uzashobora kwipimisha:
impagarike zeru
Kurwanya insulation
ubunyangamugayo bwikiraro
Impamvu yo gutsindwa imaze kumenyekana, itsinda ryanyu rirashobora guhitamo uburyo bwo gutera imbere.
Impirimbanyi zeru:
Ikizamini cya zeru gishobora gufasha kumenya niba selile yimizigo yangiritse kumubiri, nko kurenza urugero, gupakira ibintu, cyangwa kwambara ibyuma cyangwa umunaniro.Menya neza ko selile yimizigo "nta mutwaro" mbere yo gutangira.Iyo zeru zuzuye zimaze gusomwa, huza umutwaro uturemangingo twinjizamo ibintu byishimishije cyangwa byinjijwe na voltage.Gupima voltage hamwe na milivoltmeter.Mugabanye gusoma ukoresheje ibyinjijwe cyangwa ibyishimo bya voltage kugirango ubone zero zingana gusoma muri mV / V.Iki gisomwa kigomba guhuza umwimerere wumutwaro wimikorere ya selile cyangwa urupapuro rwibicuruzwa.Niba atari byo, selile yimizigo ni mibi.
Kurwanya ubwishingizi:
Kurwanya insulasiyo bipimirwa hagati yingabo ya kabili nu muzunguruko wa selile.Nyuma yo guhagarika selile yimizigo ivuye mumasanduku, huza inzira zose hamwe - ibyinjira nibisohoka.Gupima ubukana bwokwirinda hamwe na megohmmeter, bapima ubukana bwokwirinda hagati yinsinga ihujwe nu mubiri wa selile yumutwaro, hanyuma ingabo ya kabili, hanyuma amaherezo yo kurwanya insulation hagati yumubiri wimitwaro ningabo.Ibisomwa byo kurwanya insulasiyo bigomba kuba 5000 MΩ cyangwa irenga kubiraro-ku-kibazo, ikiraro-ku-cyuma, hamwe n’ingabo-ya-kabili.Indangagaciro zo hasi zerekana kumeneka guterwa nubushuhe cyangwa kwangirika kwimiti, kandi gusoma cyane ni ikimenyetso cyerekana ko kigufi, ntabwo cyinjira.
Ubusugire bw'ikiraro:
Uburinganire bwikiraro bugenzura ibyinjira nibisohoka birwanya hamwe ningamba hamwe na ohmmeter kuri buri jambo ryinjiza nibisohoka biganisha.Ukoresheje imibare yumwimerere yihariye, gereranya ibyinjira nibisohoka bivuye kuri "umusaruro mubi" na "kwinjiza nabi", na "umusaruro mubi" na "wongeyeho ibyinjijwe".Itandukaniro hagati yindangagaciro zombi rigomba kuba munsi cyangwa ingana na 5 Ω.Niba atari byo, hashobora kubaho insinga zacitse cyangwa ngufi zatewe no guhungabana imitwaro, kunyeganyega, gukuramo, cyangwa ubushyuhe bukabije.
Kurwanya ingaruka:
Ingirabuzimafatizo ziremereye zigomba guhuzwa nisoko ihamye yingufu.Noneho ukoresheje voltmeter, huza ibisohoka biyobora cyangwa terminal.Witondere, usunike imitwaro ya selile cyangwa umuzingo kugirango utangire umutwaro muto, witonde kugirango udashyira imizigo irenze.Itegereze ituze ryo gusoma hanyuma usubire mwumwimerere wa zeru usoma.Niba gusoma bidahwitse, birashobora kwerekana guhuza amashanyarazi byananiranye cyangwa inzibacyuho yamashanyarazi irashobora kwangiza umurongo uri hagati yikigereranyo hamwe nibigize.
