Nanditse kandi nsubiramo ibikoresho kuva mu 2007, kandi ingingo zashyizwe ahagaragara mu kubaka urugo rwiza, iri nzu ishaje, siyanse izwi cyane, ubushishozi n'ibikoresho by'ubucuruzi. Nakoraga kandi nk'umubaji, umutware hamwe n'umugenzuzi w'urubuga imyaka 10, bakora ku mishinga minini y'amadorari. Muri 2011, nashenye kandi inzu yanjye y'imyaka 100, yasabye gahunda nshya y'amashanyarazi.
Kubindi bisobanuro bijyanye no kubonana na voltage voltage, naganiriye nabantu babikoresha buri munsi: Mark Tierney wa Tierney Amashanyarazi, Hopkinton, Massachusetts. Tierney afite uburambe bwimyaka 20 kandi yagiye akora isosiyete ye kuva 2010.
Ikizamini kidahuza telezi ya voltage gusa gikeneye kuba hafi yo kumenya ikigezweho mumitsinga cyangwa sock. 1 Nubunini nuburyo bwa metero. Gutahura bibaho kuri probe. Mubihe byinshi, inama ya probe yagenewe gusunikwa kumurima. Kubera ko imiti yamashanyarazi idashimishije nibyiza kandi byangiza cyane, iki gikoresho ni ingirakamaro kumurimo woroheje wamashanyarazi, nko gukemura ikibazo cyo gukemura amashanyarazi cyangwa gushiraho umucyo.
Biragaragara, ni igikoresho gikomeye amashanyarazi ya diy, ariko abantu bafite imiyoboro ya zeru barashobora kungukirwa no kugira imwe. Mubisanzwe nkoresha nkicyiciro cya mbere cyo gukemura ikibazo mbere yo guhamagara amashanyarazi yumwuga.
Ikizamini kitari umunyamakuru gishobora kandi gufasha ikarita yawe iriho. Ntabwo nabayeho munzu yose hafi yinama ifatika. Niba ufite inzu ishaje cyangwa inzu ishaje, inteko yamashanyarazi birashoboka nayo. Gukemura iki kibazo ni inzira itwara igihe, ariko birashoboka. Zimya abahungu bose bashinzwe umutekano usibye umwe, hanyuma urebe ibikorwa bikikije inzu. Umaze kubimenya, andika breaker yumuzunguruko hanyuma ukomeze kurindi.
Abafatanyabikorwa benshi batavuga rumwe gusa bandika voltage zisanzwe. Nyuma yo gusoma kuriyi ngingo, twahisemo ko tester yibanze ya voltage ebyiri akwiriye kuba muri agasanduku k'ibikoresho. Kumurongo usanzwe, urashobora gukora mubisanzwe, kandi hariho inyungu zinyongera zo kumenya voltage nkeya, ni ingirakamaro kuri urugi, therwats, ibikoresho bimwe na bimwe bya av, kuhira hamwe no kuzimara ibintu. Ibiciro bya voltage-voltage hamwe na voltage-voltage imwe iri hagati ya US $ 15 na US $ 25, bityo ibikoresho bibiri byumvikana nkigikoresho kimwe kubatari abanyamwuga; Kugira ubushobozi kandi ntibikoresha ni ngombwa kuruta kubikenera no kutabitunga. Nibyiza.
Iyo duhisemo icyitegererezo cyo kugerageza, twize amazon, depo yo murugo, hamwe nibicuruzwa bigabanuka. Natwe twibasiye ibikoresho byamashanyarazi. Kuva icyo gihe, twagabanije urutonde kugeza kuri barindwi.
Twakoze ibigeragezo bimwe kugirango hamenyekane ibikorwa rusange no kumva buri kizamini. Ubwa mbere, nazimiye kumena umuzunguruko ku gasanduku k'amashanyarazi maze tugerageza kumenya icyo muri wire 35 kiva muri byo cyacitse. Nyuma yibyo, nafashe umugozi wapfuye kugirango ndebe niba nshobora kuzana igikoresho cyegereye insinga nzima kandi ndacyabona tester kugirango some nabi. Usibye ibizamini byubaka, nakoresheje tester kugirango uhuze sokorker kandi ryashyinguye ibintu bimwe na bimwe bya dimmer, kuki, abafana bakodesha hamwe na chandeliers.
Klein arashobora kubona voltage isanzwe na voltage nkeya, kandi ifite ibikoresho byoroheje-iyo urumuri ruzimye, urashobora gukenera igikoresho cyiza.
Nyuma yo gukora ubushakashatsi ku ngingo, kuganira n'amashanyarazi, no kumara amasaha agerageza icyitegererezo kirindwi cyambere, turasaba Klein NCVT-3. NCVT-3 ifite urumuri rwita ku cyerekezo, mwiza kuri / off na off na onboard yayoboye ikora nk'itara rito. Nibintu byinshi, kuko iyo ugenzuye voltage yirebi, urumuri ntirushobora gukora neza. Birahuye kandi na tamper-port sock isabwa na kode iriho. NCVT-3 ifite icyerekezo cyubuzima bwa bateri kandi umubiri urambye urinda ibikoresho bya elegitoroniki byoroshye kuva ibinure bigera kuri 6½.
Icy'ingenzi, NCVT-3 biroroshye cyane gukoresha. Nibikoresho bibiri, bityo birashobora kumenya voltage isanzwe (socket, urwango rusanzwe) kimwe na voltage nke (inzogera, thermostat, uhirita). Abafatanyabikorwa benshi babonye gusa voltage zisanzwe. Bitandukanye nizindi moderi ebyiri zibiri zibiri, irashobora guhita uhindure hagati ya rubana udakoresheje imitekerereze yoroshye. Igishushanyo cyayobowe kuruhande rwigikoresho cyerekana voltage urimo ukorana. Gutahura voltage nkeya bimurikira amatara abiri ya orange hepfo, hamwe na voltage isanzwe ya voltage yaka imwe cyangwa nyinshi mumatara atatu itukura hejuru. Ibigo byinshi bigurisha ibibanza bitandukanye kandi bike byigituro cyisumbuye kandi hasi, ariko kubatarimo babigize umwuga, byumvikana kubishyira mubikorwa bimwe, cyane cyane niba byoroshye gukora nka klein.
Mu nsi yacu bwite, insinga ziterwa no ku gisenge hejuru y'amatara ya fluorescent, bityo niyo amatara ari kuri, biragoye gukemura insinga. Muburyo bubiri hamwe namashusho, NCVT-3 niyo yonyine ishobora gukorerwa itisunze imikorere yikizamini, nibyiza rwose.
LETALLUCYERITRA FNECLALVILT ni ikintu cyaranze NCVT-3. Mu nsi yacu bwite, insinga ziterwa no ku gisenge hejuru y'amatara ya fluorescent, bityo niyo amatara ari kuri, biragoye gukemura insinga. Muburyo bubiri hamwe namashusho, NCVT-3 niyo yonyine ishobora gukorerwa itisunze imikorere yikizamini, nibyiza rwose. Iyo ikizamini gikora, hazaba urukurikirane rwa beeps n'amatara yaka. Niba ushaka gukoresha itara, nibyiza gushobora kubyirinda. Guhitamo kwacu Kwiruka, Milwaukee 2203-20 Kureka hamwe na LED nabwo bigira imikorere itarangwamo, ariko uko byagenda kose iyo ikizamini gifunguye, uko byagenda kose, mugomba no gutega amatwi Niba uri mucyumba cyaka neza uzimye itara mugihe ukorera mumujyi. NCVT-3 iyobowe nayo irabagirana kuruta Milwaukee.
NCVT-3 nayo ifite iramba ryinshi. Nk'uko uwabikoze, birashobora kwihangana igitonyanga cy'amaguru 6.5, niba rero uhuye na kugwa, iyi moderi izaguha amahirwe yo kubaho. Byongeye kandi, urufunguzo rwashyizweho kashe, kandi umupfundikizo w'icyumba cya bateri cyashyizweho kashe, bityo NCVT - 3 irashobora kwihanganira imvura nke n'ubushuhe. Klein afite videwo yerekeye igikoresho, kandi isa nkaho iri munsi yigituba.
Igihe twabajije amashanyarazi Mark Tierney aramutse asabye uwabikoze nyir'urugo, yatubwiye ati "Uwizewe cyane ni Klein." Akunda kandi moderi hamwe na LED. Yavuze ko kuba nyir'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 gukurikiza ibizamini n'amasaha 6 yo gukoresha itara ridakomeza. Ibi birahagije kubakoresha rimwe na rimwe, nkuko twabivuze, nibyiza kugira ikimenyetso cya bateri kugirango uzamenye igihe kimaze hasi.
Ntabwo ari bo bonyine bakunda NCVT-3. Umuyoboro wa Clint wanditse kuri protolution, yavuze ko igikoresho "nubwo waba ukora imirimo y'amashanyarazi rimwe na rimwe, urashobora kubibona byoroshye." Yashoje agira ati: "Iki nigikoresho cyateguwe neza gishobora gukora icyo aricyo cyose gikwiye kandi gikora. Nibyiza cyane. Tora. Ntuzabyicuza. "
NCVT-3 yakiriye kandi muri rusange isubiramo kuri depo ya Amazone na Murugo. Ibyinshi mumakuru mabi kuri Amazone ava kubantu bakunda igikoresho ariko batenguha ko bidashobora gucomeka muri sock. Nkuko byavuzwe haruguru, iki ntabwo arikibazo kuko gishobora kumenya ikigezweho kandi kikagaragaza nka voltage nkeya (hanyuma uhuze na soke ya tamper isabwa na kode). Kugirango wemeze mubyukuri voltage isanzwe kuri sock, biroroshye gukuramo igifuniko hanyuma ushireho isonga ryigikoresho kuruhande rwa sock aho insinga ziherereye.
NCVT-3 irihariye kuko idashobora gucomeka muri sock. Urebye neza, ibi bisa nkibibazo, nkuko abandi benshi batavuga rumwe na bimwe bidahamagara birashobora gusoma imbaraga ziva kuri sock gusa mugushiramo. Ukuri nuko kuko ishobora gusoma voltage nkeya, NCVT-3 irashobora gushushanya kuva hanze ya sock, ni ngombwa mugihe uhuye nibitekerezo-byerekana amasoko yamashanyarazi. Kwinjizamo gucomeka muri socketi imwe, igitutu kimwe gikeneye gukoreshwa kuri pin ebyiri (iki nikibazo cyumutekano kubana). Hamwe nayi soketi, umuvuduko gakondo udahuza testeri ya voltage ntabwo buri gihe ukora kuko ishobora gusoma gusa voltage zisanzwe. Nkuko Bruce Kuhn, Umuyobozi w'igicuruzwa mu iterambere ry'ibicuruzwa, ikizamini no gupima kuri Klein, yatubwiye ati: "Niba ukora ikizamini nk'iki gihagije kugira ngo umenye voltage kuri voltage 'ya tamper-port-mubantu benshi agasanduku k'amashanyarazi. Insinga zishyushye. " 2 Kuberako NCVT-3 yagenewe gutahura voltage isanzwe na voltage nkeya, iyo ishyizwe mu gufungura sock-port sock-port sock-port sock risanzwe, ariko kure, bigaragara ko ari voltage nkeya, biracyaremeza ko sock atuyemo.
Hano hari buto yo kugenzura kuruhande rwa NCVT-3, Tierney yatubwiye kwitondera. Yihanangirije ko moderi zifite utubuto zo ku mpande ziroroshye gufungura mugihe zashyizwe mu mufuka, udajuririye gusa, ahubwo unihutire gukoresha bateri. Itandukaniro rimwe kuva NCVT-3 nuko buto ari hejuru; buto myinshi nkiyi sohoka kuruhande rwigikoresho kandi irashobora gukora kubwimpanuka. Nakoresheje NCVT-3 mumufuka kumunsi, kandi ntiyigeze ufungura.
Iyi dister ya voltage ya voltage ebyiri isa no guhitamo muburyo bwingenzi, ariko bimwe mubisobanuro bito byayo birababaje.
Niba Klein ataboneka, turasaba kolwaukee 2203-20 statector voltage hamwe nayo. Ifite imirimo myinshi nka Klein NCVT-3, ariko itara ntabwo risobanutse kandi ntirishobora gukoreshwa byigenga. Iratanga kandi beep ya beep idasanzwe (nta guhitamo ibiragi). Ibi birashobora kuba ingirakamaro mu rubuga rwakazi, ariko nyuma yo kumara iminota 45 kugenzura insinga ziri mu nsi yo munsi, ingano yari ihagije yo kuntera umusazi muto.
Nubwo bimeze bityo, Milwaukee ashobora kumenya voltage nkeya na voltage isanzwe, kandi nta mfashanyo ihinduka hagati yabo, bityo biraryoroshye gukoresha nka NCVT-3.
Muri 2019, twabonye ko Klein ubu afite NCVT-4ir. Irasa kimwe no guhitamo kwacu, ariko kandi ikubiyemo imikorere ya thermometero. Twizera ko ibyo bidakwiriye kwiyongera kubikoresha murugo.
Twabonye kandi moderi y'ibigo nka Meterk, Tohayie, umurizo, na Socll. Ibi nibikoresho bisanzwe biva mubigo bito bizwi. Twumva ko ari byiza gutanga ibyemezo kuva mumashanyarazi agenzurwa.
Twagerageje Klein NCVT-2, bisa cyane na NCVT-3. Nuburyo kandi bubiri bubiri bushobora guhita kumenya hagati yimibare ibiri, ariko ntabwo ifite iyobowe; Akabuto ka / off irabishima (birashoboka rero gukingurwa mumufuka); kandi urubanza ntirufite uwo baramba.
Twabonye kandi Greenlee GT-16 na Sperry Vd6505 koresha terefone kugirango uhitemo sensibite hagati ya voltage nkeya na voltage isanzwe. Mugihe c'ikigeragezo, twasanze iyo hari insinga nyinshi, izo moderi zizakira ibimenyetso biva ku zindi nsinga, bituma bitugora kumenya igihe sensibitivite iragabanuka kugirango itange insinga gusa dushaka. Biragoye kumenya amayeri yibiganiro byumva, hanyuma uhitemo imigaragarire yoroshye ya Milwaukee na Kleins.
Greenlee Tr-12a afite igishushanyo mbonera cyinshi kuri tamper-ponduke ya tamper-yerekana gusa, ahubwo irashobora gusoma voltage zisanzwe, bityo turatekereza ko NCVT-3 ifite akamaro.
Klein ncvt-1 kumenya voltage isanzwe. Ntabwo nari mfite imyaka myinshi kandi buri gihe, nasanze ari ukuri kandi kwizewe, ariko byumvikana kubona icyitegererezo gishobora no kumenya voltage nkeya.
Twabajije Klein gusobanura neza ihame ryakazi ryibitabo bitavuga rumwe na voltage. Isosiyete yatubwiye iti: "Igikoresho kitari cyo guhuza voltage gikora mu gushishikariza umurima w'amaguru watewe n'umuyobozi ushingiye ku murongo wakozwe na disikuru ikozwe mu buryo bundi (AC). Muri rusange, voltage yakoresheje umuyobozi, ikomeye cyane imbaraga zumurima wibintu bihuye nakururwa na elecraromagnetic. Sensor mubikoresho bitarinama bisubiza ukurikije imbaraga zumurima zamateka ya elecraromagnetic. Dushingiye kuri iri hame, mugihe ibitagira inama voltage voltage ari hafi yuyobora ingufu mugihe yashyizwemo imbaraga zo "kumenya" muburyo bwo kumenya igikoresho cyangwa mukibuga kinini. "
Nafashe Klein NCVT-1 hafi y'urugo rwanjye. Ibona gusa voltage zisanzwe. Ikigereranyo cyo gutsinda cyo gutahura imbaraga ziva muri Tamper-Porogaramu ni 75%.
