Ikizamini kidahuye nacyo gishobora gufasha gushushanya sisitemu y'amashanyarazi iriho.Ntabwo nabaye munzu iyo ari yo yose yegereye ikibaho cyanditse neza.Niba ufite inzu ishaje cyangwa inzu, icyuma cyamashanyarazi nacyo cyanditse nabi.Gukemura iki kibazo ni inzira itwara igihe, ariko birashoboka.Zimya ibyuma byose byumuzunguruko usibye kimwe, hanyuma urebe ibikorwa bikikije inzu.Umaze kubimenya, andika inzitizi zumuzingi hanyuma ukomeze kurindi.
Abagerageza benshi badahuza gusa bandika voltage zisanzwe.Nyuma yo gusoma kubyerekeye isomo, twahisemo ko ibipimo bibiri bya voltage bipimisha bikwiranye nagasanduku k'ibikoresho byo murugo.Kuri voltage isanzwe, irashobora gukora mubisanzwe, kandi hariho inyungu zinyongera zo gutahura voltage nkeya, ifasha mugukomanga kumuryango, thermostat, ibikoresho bimwe na bimwe AV, kuhira no kumurika ahantu nyaburanga.Ibiciro bya moderi ebyiri n’umuvuduko umwe uri hagati y’amadolari ya Amerika 15 na US $ 25, bityo ibikoresho byombi bigasobanuka nkigikoresho kimwe cyo guhagarika abadafite umwuga;kugira ubushobozi no kutayikoresha ni ngombwa kuruta kubikenera no kutabitunga.byiza.
Mugihe duhitamo icyitegererezo cyo kugerageza, twize Amazon, Home Depot, hamwe na Lowes ibicuruzwa.Twibanze kandi kubakora ibikoresho bizwi cyane.Kuva icyo gihe, twagabanije urutonde kuri barindwi.
Twakoze ibizamini kugirango tumenye ibikorwa rusange hamwe na sensibilité ya buri kizamini.Ubwa mbere, nazimije icyuma cyumuzunguruko ku gasanduku k'amashanyarazi ngerageza kumenya imwe mu nsinga 35 zavuyemo zacitse.Nyuma yibyo, nafashe umugozi wapfuye kugirango ndebe niba nshobora kuzana igikoresho hafi y'insinga nzima kandi nkabona ibizamini byo gusoma nabi.Usibye ibi bizamini byubatswe, nakoresheje kandi ibizamini kugirango mpuze socket zimwe hanyuma nshiraho utuntu duto twa dimmer, guteka, abafana b'igisenge hamwe na chandeliers.
Klein irashobora kumenya voltage isanzwe hamwe na voltage ntoya, kandi ifite itara ryoroshye-mugihe urumuri ruzimye, ushobora gukenera igikoresho cyiza.
Nyuma yo gukora ubushakashatsi ku ngingo, kuganira naba mashanyarazi, no kumara amasaha agerageza moderi zirindwi ziyobora, turasaba Klein NCVT-3.NCVT-3 ifite urumuri rwerekana cyane, urumuri rwiza kuri / kuzimya hamwe na LED kumurongo ikora nk'itara rito.Iki nikintu gikomeye, kuko iyo ugenzuye voltage ya wire, urumuri ntirushobora gukora neza.Irashobora kandi guhuza na tamper-idashobora gukoreshwa na code iriho.NCVT-3 ifite ibipimo byubuzima bwa bateri numubiri uramba urinda ibikoresho byayo bya elegitoroniki byoroshye kumanuka kugera kuri metero 6½.
Icyingenzi cyane, NCVT-3 iroroshye gukoresha.Nibikoresho bibiri, kuburyo ishobora kumenya voltage isanzwe (socket, insinga zisanzwe) kimwe na voltage nkeya (inzogera yumuryango, thermostat, insinga zo kuhira).Abapimisha benshi bamenya gusa voltage zisanzwe.Bitandukanye nubundi buryo bubiri-buringaniye, burashobora guhita buhinduranya hagati yumurongo udakoresheje imvugo itoroshye.Igishushanyo mbonera cya LED kuruhande rwigikoresho cyerekana voltage urimo ukora.Umuvuduko muke wa voltage ucana amatara abiri ya orange hepfo, naho voltage isanzwe yaka imwe cyangwa nyinshi mumatara atatu atukura hejuru.Ibigo byinshi bigurisha ibyuma bitandukanya umuvuduko mwinshi kandi muto, ariko kubatari abanyamwuga, birumvikana kubishyira mubikoresho bimwe, cyane cyane niba byoroshye gukora nka Klein.
Mu cyumba cyanjye bwite, insinga zometse ku gisenge hejuru y’amatara ya fluorescent, bityo niyo amatara yaba yaka, biragoye gukoresha insinga.Muri moderi ebyiri zifite amatara, NCVT-3 niyo yonyine ishobora gukoreshwa itisunze imikorere yikizamini, nibyiza rwose.
Amatara ya LED ni ikintu cyerekana NCVT-3.Mu cyumba cyanjye bwite, insinga zometse ku gisenge hejuru y’amatara ya fluorescent, ku buryo niyo amatara yaba yaka, biragoye gukoresha insinga.Muri moderi ebyiri zifite amatara, NCVT-3 niyo yonyine ishobora gukoreshwa itisunze imikorere yikizamini, nibyiza rwose.Mugihe ikizamini gikora, hazaba urukurikirane rwa beeps n'amatara yaka.Niba ushaka gukoresha itara gusa, nibyiza kubasha kubyirinda.Guhitamo kwacu-kwiruka, Milwaukee 2203-20 ya voltage detector hamwe na LED nayo ifite imikorere yamatara, ariko izamurika gusa mugihe ikizamini gifunguye, uko byagenda kose, ugomba kumva amajwi, nta kuntu ndetse niba uri mucyumba cyaka cyane Zimya itara mugihe ukorera mumujyi.NCVT-3 LED nayo irasa kurusha Milwaukee.
NCVT-3 nayo ifite ibyiyumvo biramba cyane.Nk’uko uwabikoze abivuga, irashobora kwihanganira kugabanuka kwa metero 6.5, niba rero uhuye nikibazo, iyi moderi izaguha amahirwe yo kubaho.Byongeye kandi, urufunguzo rufunze, kandi umupfundikizo wigice cya batiri urafunzwe, bityo NCVT-3 irashobora kwihanganira imvura nubushuhe buke.Klein afite videwo yerekeye igikoresho, kandi isa nkaho iri munsi yigitonyanga.
Tumubajije umuyagankuba Mark Tierney niba yosaba uruganda urwo arirwo rwose nyir'urugo, yatubwiye ati "uwizewe cyane ni Klein."Akunda kandi moderi zifite LED.Yavuze ko kuri banyiri amazu, “bazabona ibintu bibiri bikomeye mu gikoresho kimwe.”
Ku bijyanye n'ubuzima bwa bateri, Klein yavuze ko bateri ebyiri za AAA zizatanga amasaha 15 yo gukoresha ibizamini bikomeza n'amasaha 6 yo gukoresha itara rihoraho.Ibi birahagije kubakoresha rimwe na rimwe, nkuko twabivuze, nibyiza kugira igipimo cya batiri kugirango uzamenye igihe kijye hasi.
Ntabwo ari twe twenyine dukunda NCVT-3.Clint DeBoer wanditse kuri ProToolReviews, yavuze ko igikoresho “Nubwo ukora akazi k'amashanyarazi rimwe na rimwe, ushobora kukibona byoroshye.”Yashoje agira ati: “Iki ni igikoresho cyateguwe neza gishobora gukora ibyo gikwiye no gukora.Byiza cyane.Tora imwe.Ntuzicuza. ”
NCVT-3 nayo yakiriye neza muri rusange Amazone na Depot yo murugo.Amenshi mu makuru mabi kuri Amazone aturuka kubantu bakunda igikoresho ariko bakababazwa nuko kidashobora gucomeka muri sock.Nkuko byavuzwe haruguru, ntabwo arikibazo kuko kiracyashobora kumenya ikigezweho kandi kikerekana gusa nka voltage ntoya (kandi ikagihuza na sock-proof sock isabwa na code).Kugirango rwose wemeze voltage isanzwe kuri sock, biroroshye gukuramo igifuniko no gushyira umutwe wigikoresho kuruhande rwa sock aho insinga ziherereye.
NCVT-3 irihariye kuko ntishobora gucomeka muri sock.Urebye neza, ibi bisa nkikibazo, kuko abandi benshi bapimisha badahuza bashobora gusoma imbaraga ziva muri sock bakayinjiza mumfunguzo.Ikigaragara ni uko kubera ko ishobora gusoma voltage nkeya, NCVT-3 irashobora gushushanya imiyoboro iva hanze ya sock, ibyo bikaba ari ingenzi cyane mugihe ukorana na sock-idashobora gukoreshwa ubu ikaba ikenewe na kode y'amashanyarazi.Kugirango winjize icyuma muri imwe muri socket, igitutu kingana kigomba gukoreshwa kumyanya ibiri ifunguye (iki nikibazo cyumutekano kubana).Hamwe nizi socket, ibizamini bya gakondo bidahuza na tester ntabwo buri gihe bikora kuko irashobora gusoma gusa voltage zisanzwe.Nkuko Bruce Kuhn, umuyobozi wibicuruzwa biteza imbere ibicuruzwa, ibizamini nogupima muri Klein, yabidutangarije ati: "Niba ukora ikizamini nkiki kuburyo bworoshye kugirango umenye voltage kuri 'hanze' ya sokeri itagira tamper, noneho iba iri mubantu benshi agasanduku k'amashanyarazi.Umugozi ushyushye. ”2 Kuberako NCVT-3 yagenewe kumenya voltage isanzwe na voltage ntoya, mugihe ishyizwe mugukingura sisitemu nzima ya tamper idashobora gukoreshwa, izatwara voltage isanzwe, ariko uhereye kure, bigaragara ko ari Umuvuduko muke, uracyemeza ko sock ari nzima.
Hano hari buto yo kugenzura kuruhande rwa NCVT-3, Tierney yatubwiye kubyitondera.Yagabishije ko imideli ifite buto yo ku mpande byoroshye gufungura iyo ishyizwe mu mufuka, ibyo ntibibabaza gusa, ariko kandi byihutisha gukoresha bateri.Itandukaniro rimwe na NCVT-3 ni uko utubuto dusukuye hejuru;buto nyinshi nkiyi isohoka kuruhande rwigikoresho kandi irashobora gukora kuburyo butunguranye.Nakoresheje NCVT-3 mu mufuka umunsi umwe, kandi ntabwo yigeze ifungura.
Igeragezwa rya voltage ebyiri isa nuguhitamo kwacu mubyingenzi, ariko bimwe mubisobanuro byayo bito birababaje.
Niba Klein itaboneka, turasaba inama ya Milwaukee 2203-20 yerekana amashanyarazi hamwe na LED.Ifite imirimo myinshi imwe na Klein NCVT-3, ariko itara ntirimurika kandi ntirishobora gukoreshwa ryigenga ryipimishije.Isohora kandi amajwi arenga adasanzwe (nta guhitamo ibiragi).Ibi birashobora kuba ingirakamaro kurubuga rwakazi rusakuza, ariko nyuma yo kumara iminota 45 ngenzura insinga ziri munsi yo hasi, amajwi yari ahagije kugirango nsaze gato.
Nubwo bimeze bityo ariko, Milwaukee irashobora gutahura voltage ntoya na voltage isanzwe, kandi ntanumwe uhindura intoki hagati yabo, kuburyo byoroshye gukoresha nka NCVT-3.
Muri 2019, twabonye ko Klein ubu afite NCVT-4IR.Irasa nkaho twahisemo, ariko kandi ikubiyemo imikorere ya infrarafarike ya termometero.Twizera ko ibyo bidakwiriye kongera ikiguzi cyo gukoresha urugo rusanzwe.
Twabonye kandi moderi zo mubigo nka Meterk, ToHayie, Taiss, na SOCLL.Ibi nibikoresho bisanzwe biva mubigo bitazwi.Twumva ko ari byiza gusaba abapimisha ibikoresho byabashakashatsi bapima amashanyarazi.
Twagerageje Klein NCVT-2, isa cyane na NCVT-3.Nuburyo bubiri-moderi ishobora guhita imenya hagati yimirongo ibiri, ariko ntabwo ifite LED;buto kuri / kuri buto irabyishimiye (birashoboka rero ko byafungurwa mumufuka);kandi urubanza ntirufite ibyiyumvo biramba.
Twabonye kandi Greenlee GT-16 na Sperry VD6505 bakoresha terefone kugirango bahitemo sensibilité hagati ya voltage nto na voltage isanzwe.Mugihe cyo kwipimisha kwacu, twasanze mugihe muri ako karere hari insinga nyinshi, izo moderi zizakira ibimenyetso biturutse ku zindi nsinga, bigatuma bitugora kumenya igihe sensitivite yagabanutse bihagije kugirango tumenye insinga dushaka gusa.Biragoye kumenya amayeri yo kwiyumvisha ibintu, hanyuma ugahitamo intera yoroshye ya Milwaukee na Kleins.
Greenlee TR-12A ifite igishushanyo cya pin ebyiri kubushakashatsi bwihariye bwa tamper, ariko irashobora gusoma gusa voltage zisanzwe aho kuba voltage nkeya, kuburyo twibwira ko NCVT-3 ari ingirakamaro cyane.
Klein NCVT-1 itahura gusa voltage isanzwe.Natunze imwe mumyaka myinshi kandi buri gihe nasanze ari ukuri kandi yizewe, ariko birumvikana kubona moderi ishobora no kumenya voltage nkeya.
Twasabye Klein gusobanura neza ihame ryakazi ryikizamini cya voltage idahuza.Isosiyete yadutangarije iti: “Igikoresho kitamenyesha ingufu za voltage sensing ikora mu gutera umurima wa electromagnetiki ukomoka ku muyoboro ukoreshwa n’isoko risimburana (AC).Muri rusange, Iyo hejuru ya voltage ikoreshwa kumuyobora, niko imbaraga zumurima zumuriro uhuye na electromagnetic.Rukuruzi mu bikoresho byo gupima bidahuye irasubiza ukurikije imbaraga zumurima wumuriro wa electromagnetic.Hashingiwe kuri iri hame, iyo igeragezwa ridahuza voltage ryegereye umuyoboro ufite ingufu Iyo rishyizwe, imbaraga zumuriro wa electromagnetique zitera igikoresho "kumenya" niba kiri mumashanyarazi make cyangwa mumashanyarazi menshi. "
Nafashe Klein NCVT-1 hafi y'urugo rwanjye.Itahura gusa voltage zisanzwe.Intsinzi yo kumenya imbaraga ziva muri socket-tamper-hafi ya 75%.
