Ndakhala ndikulemba ndi kuwunikira zida kuyambira 2007, ndipo zolemba zasindikizidwa mu Fine Homebuilding, Nyumba Yakale iyi, Sayansi Yodziwika, Makina Otchuka ndi Zida Zamalonda.Ndinagwiranso ntchito ngati kalipentala, foromani ndi woyang’anira malo kwa zaka 10, ndikugwira ntchito yomanga nyumba zokhalamo zokhala ndi madola mamiliyoni ambiri.Mu 2011, ndinagwetsanso nyumba yanga ya famu ya zaka 100, zomwe zinafunika magetsi atsopano.
Kuti mumve zambiri za oyesa ma voltage osalumikizana, ndidalankhula ndi anthu omwe amawagwiritsa ntchito tsiku lililonse: Mark Tierney waku Tierney Electrical, Hopkinton, Massachusetts.Tierney ali ndi zaka 20 ndipo wakhala akuyendetsa kampani yake kuyambira 2010.
Woyesa magetsi osalumikizana amangofunika kukhala pafupi kuti azindikire zomwe zili muwaya kapena soketi.1 Ndi kukula ndi mawonekedwe a mafuta akuthwa.Kuzindikira kumachitika pa nsonga ya kafukufuku.Nthawi zambiri, nsonga ya probe imapangidwa kuti ikankhidwe kumtunda.Popeza kugwedezeka kwamagetsi sikosangalatsa kwambiri komanso kumavulaza kwambiri, chida ichi ndi chothandiza ngakhale pamagetsi opepuka kwambiri, monga kuthetsa vuto la thermostat kapena kukhazikitsa dimmer switch.
Mwachiwonekere, ndi chida chabwino kwa opanga magetsi a DIY, koma ngakhale anthu omwe ali ndi zero zamagetsi amatha kupindula pokhala nawo.Nthawi zambiri ndimagwiritsa ntchito ngati gawo loyamba lazovuta ndisanayitane katswiri wamagetsi.
Woyesa osalumikizana angathandizenso kupanga mapu amagetsi omwe alipo.Sindinakhale m'nyumba iliyonse pafupi ndi gulu lolondola lolembedwa.Ngati muli ndi nyumba yakale kapena nyumba, magetsi anu amalembedwa molakwika.Kuthetsa vutoli ndi nthawi yambiri, koma n'zotheka.Zimitsani zowononga zonse kupatula imodzi, ndiyeno fufuzani zochitika zapanyumba.Mukazindikira, lembani chophwanyira dera ndikupita ku yotsatira.
Oyesa ambiri osalumikizana amangolemba ma voltages wamba.Titawerenga za nkhaniyi, tidaganiza kuti choyesa chamagetsi chapawiri ndi choyenera mabokosi anyumba.Pamagetsi okhazikika, amatha kugwirabe ntchito bwino, ndipo palinso phindu lowonjezera lamagetsi otsika, omwe ndi othandiza pamabelu apakhomo, ma thermostat, zida zina za AV, ulimi wothirira ndi kuyatsa kwamalo.Mitengo yamitundu iwiri yamagetsi ndi imodzi yokha imakhala pakati pa US $ 15 ndi US $ 25, kotero kuti zipangizo zamitundu iwiri zimakhala zomveka ngati chida choyimitsa chimodzi kwa omwe si akatswiri;kukhala ndi kuthekera ndi kusaugwiritsa ntchito ndikofunikira kuposa kuufuna osati kukhala nawo.zabwino.
Posankha mitundu yoti tiyese, tidaphunzira za Amazon, Home Depot, ndi Lowes.Tayang'ananso opanga zida zamagetsi zodziwika bwino.Kuyambira pamenepo, tachepetsa mndandanda mpaka asanu ndi awiri.
Tidayesa mayeso kuti tidziwe momwe woyesa aliyense angakhudzire zochita zake zonse.Choyamba, ndinazimitsa makina othyola magetsi pabokosi lamagetsi ndikuyesera kupeza kuti mwa mawaya 35 otulukamo ndi iti yomwe inathyoka.Pambuyo pake, ndidatenga waya wakufa kuti ndiwone ngati ndingabweretse chidacho pafupi ndi waya wamoyo ndikupangitsa kuti woyesa awerenge kuti alibe.Kuphatikiza pa mayeso apangidwe awa, ndidagwiritsanso ntchito choyesa kulumikiza sockets ndikuyika masiwichi a dimmer, ma cooktops, mafani a padenga ndi ma chandeliers ena.
Klein imatha kuzindikira voteji wamba ndi magetsi otsika, ndipo ili ndi tochi yothandiza - nyali ikazima, mungafunike chida chabwino.
Pambuyo pofufuza mitu, kuyankhula ndi akatswiri amagetsi, ndikugwiritsa ntchito maola ambiri kuyesa zitsanzo zisanu ndi ziwiri zotsogola, timalimbikitsa Klein NCVT-3.NCVT-3 ili ndi kuwala kowoneka bwino kwambiri, batani lokongola loyatsa / lozimitsa ndi nyali yapabwalo ya LED yomwe imagwira ntchito ngati tochi yaying'ono.Ichi ndi chinthu chabwino, chifukwa mukayang'ana waya wamagetsi, kuwalako sikungagwire ntchito bwino.Zimagwirizananso ndi socket-proof socket yofunikira ndi code yomwe ilipo.NCVT-3 ili ndi chizindikiro cha moyo wa batri ndi thupi lolimba lomwe limateteza zida zake zamagetsi kuti zisamadonthodwe mpaka 6½ mapazi.
Chofunika kwambiri, NCVT-3 ndiyosavuta kugwiritsa ntchito.Ndi chipangizo chapawiri, chomwe chimatha kuzindikira ma voltages wamba (sockets, wiring wamba) komanso ma voltages otsika (belu lapakhomo, thermostat, waya wothirira).Oyesa ambiri amangowona ma voltages wamba.Mosiyana ndi mitundu ina yambiri yamitundu iwiri, imatha kusinthana pakati pamagulu osagwiritsa ntchito kuyimba kovutirapo.Chithunzi cha bar cha LED chomwe chili kumbali ya chida chikuwonetsa mphamvu yomwe mukuchita nayo.Kuzindikira kwamagetsi otsika kumayatsa magetsi awiri alalanje pansi, ndipo magetsi okhazikika amawunikira limodzi kapena zingapo mwa nyali zofiira zitatu pamwamba.Makampani ambiri amagulitsa zowunikira zotsika kwambiri komanso zotsika, koma kwa omwe si akatswiri, ndizomveka kuziyika mu chida chimodzi, makamaka ngati ndizosavuta kugwira ntchito ngati Klein.
M'chipinda changa chapansi, mawaya amakhomeredwa padenga pamwamba pa nyali za fulorosenti, kotero kuti ngakhale magetsi ayaka, zimakhala zovuta kugwira mawaya.Mwa mitundu iwiri yokhala ndi tochi, NCVT-3 ndiyo yokhayo yomwe imatha kuyendetsedwa mosadalira ntchito yoyeserera, yomwe ili yabwino kwambiri.
Tochi ya LED ndi chowunikira cha NCVT-3.M'chipinda changa chapansi, mawaya amakhomeredwa padenga pamwamba pa nyali za fulorosenti, kotero kuti ngakhale magetsi ayaka, zimakhala zovuta kugwira mawaya.Mwa mitundu iwiri yokhala ndi tochi, NCVT-3 ndiyo yokhayo yomwe imatha kuyendetsedwa mosadalira ntchito yoyeserera, yomwe ili yabwino kwambiri.Woyesa akatsegulidwa, padzakhala ma beep angapo ndi nyali zowunikira.Ngati mumangofuna kugwiritsa ntchito tochi, ndi bwino kuti mupewe.Chosankha chathu chothamanga, Milwaukee 2203-20 voltage detector yokhala ndi LED imakhalanso ndi ntchito ya tochi, koma idzangoyatsa pamene tester yatsegulidwa, choncho, muyenera kumvetsera kulira, palibe njira ngakhale. ngati muli m'chipinda chowala bwino Zimitsani tochi mukamagwira ntchito mumzinda.NCVT-3 LED ndi yowala kuposa Milwaukee.
NCVT-3 imakhalanso ndi kumverera kolimba kwambiri.Malinga ndi wopanga, imatha kupirira kutsika kwa 6.5-foot, kotero ngati mukukumana ndi kugwa, chitsanzo ichi chidzakupatsani mwayi wopulumuka.Kuonjezera apo, makiyi amasindikizidwa, ndipo chivindikiro cha chipinda cha batri chimasindikizidwa, kotero NCVT-3 ikhoza kupirira mvula yochepa ndi chinyezi.Klein ali ndi kanema wokhudza chidacho, ndipo chikuwoneka ngati chiri pansi pa mpopi wodontha.
Titafunsa katswiri wamagetsi Mark Tierney ngati angapangire wopanga aliyense kwa eni nyumba, adatiuza kuti "wodalirika kwambiri ndi Klein."Amakondanso zitsanzo zokhala ndi ma LED.Anati kwa eni nyumba, "adzapeza zinthu ziwiri zabwino kwambiri pachida chimodzi."
Ponena za moyo wa batri, Klein adanena kuti mabatire awiri a AAA adzapereka maola 15 ogwiritsira ntchito tester mosalekeza ndi maola 6 ogwiritsira ntchito tochi mosalekeza.Izi ndizokwanira kwa ogwiritsa ntchito apo ndi apo, monga tidanenera, ndizabwino kukhala ndi chizindikiro cha batri kuti mudziwe ikatsika.
Si ife tokha omwe timakonda NCVT-3.Clint DeBoer, yemwe adalemba pa ProToolReviews, adati chida "Ngakhale mumagwira ntchito yamagetsi nthawi zina, mutha kuchipeza mosavuta."Iye anamaliza ndi mawu akuti: “Ichi ndi chida chopangidwa bwino chomwe chimatha kuchita zomwe chiyenera kuchita ndi kuchita.Zabwino kwambiri.Sankhani chimodzi.Simudzanong’oneza bondo.”
NCVT-3 yalandilanso ndemanga zabwino pa Amazon ndi Home Depot.Nkhani zoipa zambiri pa Amazon zimachokera kwa anthu omwe amakonda chidacho koma amakhumudwitsidwa kuti sichikhoza kulumikizidwa mu socket.Monga tafotokozera pamwambapa, izi sizovuta chifukwa zimatha kuzindikira zomwe zilipo ndikuziwonetsa ngati magetsi otsika (ndikupangitsa kuti zigwirizane ndi socket-proof socket yofunikira ndi code).Kuti mutsimikizire kwenikweni mphamvu yamagetsi pazitsulo, n'zosavuta kumasula chivundikirocho ndikuyika nsonga ya chida kumbali ya socket yomwe mawaya ali.
NCVT-3 ndi yapadera chifukwa sichitha kulumikizidwa mu socket.Poyang'ana koyamba, izi zikuwoneka ngati vuto, popeza ambiri oyesa osalumikizana amatha kuwerenga mphamvu kuchokera pasoketi pongoyiyika potsegula.Chowonadi ndi chakuti chifukwa imatha kuwerengera ma voltages otsika, NCVT-3 imatha kutulutsanso zamakono kuchokera kunja kwa socket, zomwe ndizofunikira kwambiri polimbana ndi sockets-proof sockets zomwe zimafunidwa ndi ma code amagetsi.Kuti muyike pulagi mu imodzi mwa sockets, kukakamiza kofanana kumafunika pamitseko iwiri ya pini (iyi ndi nkhani yachitetezo kwa ana).Ndi soketi izi, choyesa chamagetsi chosalumikizana sichigwira ntchito nthawi zonse chifukwa chimangowerenga ma voltages wamba.Monga a Bruce Kuhn, director of product development, test and measurement ku Klein, adatiuza kuti, "Ngati mupanga choyesa chotere kuti chizitha kuzindikira mphamvu ya 'kunja' kwa socket-proof socket, ndiye kuti ili ndi anthu ambiri. bokosi lamagetsi.Waya wotentha."2 Chifukwa NCVT-3 lakonzedwa kuti azindikire muyezo voteji ndi otsika voteji, pamene anayikidwa mu kutsegula kwa moyo tamper-umboni zitsulo, izo kutenga voteji muyezo, koma patali, zikuoneka kuti otsika Voltage, tsimikiziranibe kuti socket ili moyo.
Pali mabatani owongolera kumbali ya NCVT-3, yomwe Tierney adatiuza kuti tizimvera.Anachenjeza kuti zitsanzo zokhala ndi mabatani am'mbali ndizosavuta kutsegula zikaikidwa m'thumba, zomwe sizimangokwiyitsa, komanso zimafulumizitsa kugwiritsa ntchito batri.Kusiyanitsa kumodzi kuchokera ku NCVT-3 ndikuti mabataniwo ndi otsika;mabatani ambiri ngati awa amatuluka m'mbali mwa chida ndipo amatha kutsegulidwa mwangozi.Ndinagwiritsa ntchito NCVT-3 m'thumba langa kwa tsiku, ndipo sichinatsegulidwe.
Izi zapawiri zoyesa magetsi ndizofanana ndi zomwe timasankha pazinthu zofunika kwambiri, koma zina zake zazing'ono ndizokwiyitsa kwambiri.
Ngati Klein palibe, timalimbikitsa Milwaukee 2203-20 voltage detector yokhala ndi LED.Ili ndi ntchito zambiri zofanana ndi Klein NCVT-3, koma tochi si yowala ndipo sangagwiritsidwe ntchito paokha poyesa.Imatulutsanso beep mokweza kwambiri (palibe njira yolankhula).Izi zitha kukhala zopindulitsa pamalo ogwirira ntchito aphokoso, koma nditatha mphindi 45 ndikuyang'ana mawaya m'chipinda chapansi, voliyumuyo inali yokwanira kundipangitsa kukhala wamisala pang'ono.
Komabe, Milwaukee akhoza kudziwa otsika voteji ndi muyezo voteji, ndipo palibe lophimba Buku pakati pawo, kotero n'zosavuta kugwiritsa ntchito NCVT-3.
Mu 2019, tidazindikira kuti Klein tsopano ali ndi NCVT-4IR.Zikuwoneka chimodzimodzi ndi zomwe tasankha, komanso zimaphatikizapo ntchito ya thermometer ya infrared.Tikukhulupirira kuti izi sizoyenera kukweza mtengo wogwiritsa ntchito nthawi zonse kunyumba.
Tidawonanso zitsanzo kuchokera kumakampani monga Meterk, ToHayie, Taiss, ndi SOCLL.Izi ndi zida zodziwika bwino kuchokera kumakampani osadziwika bwino.Tikuwona kuti ndikotetezeka kupangira oyesa kuchokera kwa opanga zida zowunikira zamagetsi.
Tinayesa Klein NCVT-2, yomwe ndi yofanana kwambiri ndi NCVT-3.Ilinso mtundu wamitundu iwiri yomwe imatha kuzindikira pakati pamitundu iwiri, koma ilibe LED;batani la / off limanyadira (kotero likhoza kutsegulidwa m'thumba);ndipo mlanduwo ulibe kumverera kokhalitsa.
Tawonanso Greenlee GT-16 ndi Sperry VD6505 akugwiritsa ntchito kuyimba kuti asankhe tcheru pakati pa magetsi otsika ndi magetsi okhazikika.Pakuyesa kwathu, tapeza kuti pakakhala mawaya angapo m'derali, zitsanzozi zidzalandira zizindikiro kuchokera ku mawaya ena, zomwe zimapangitsa kuti zikhale zovuta kuti tidziwe pamene kukhudzidwa kumachepetsedwa kuti tizindikire mawaya okha omwe tikufuna.Ndizovuta kudziwa zidule za ma dials okhudzidwa, ndimakonda mawonekedwe osavuta a Milwaukee ndi Kleins.
Greenlee TR-12A ali ndi mapini awiri mapangidwe makamaka tamper-proof sockets, koma amatha kuwerenga ma voltages muyezo m'malo motsika ma voltages, kotero tikuganiza kuti NCVT-3 ndiyothandiza kwambiri.
Klein NCVT-1 amangozindikira voteji muyezo.Ndakhala ndi imodzi kwa zaka zambiri ndipo ndakhala ndikuiwona kuti ndiyolondola komanso yodalirika, koma ndizomveka kupeza chitsanzo chomwe chimatha kuzindikiranso ma voltages otsika.
Tinapempha Klein kuti afotokoze molondola mfundo yogwiritsira ntchito magetsi osalumikizana.Kampaniyo idatiuza kuti: "Chida chodziwikiratu chomwe sichimalumikizana ndi magetsi chimagwira ntchito pokopa mphamvu yamagetsi yomwe imayendetsedwa mozungulira kondakitala yoyendetsedwa ndi gwero lamakono (AC).Nthawi zambiri, Kukwera kwa voteji komwe kumagwiritsidwa ntchito kwa kondakitala, kumapangitsanso mphamvu yakumunda ya gawo lofananira ndi ma elekitiroma.Sensor mu zida zoyesera zosalumikizana imayankha molingana ndi mphamvu yamunda wa gawo lopangidwa ndi ma elekitiroma.Kutengera mfundo imeneyi, pamene choyesa voteji chomwe sichimalumikizana chili pafupi ndi kondakita wamagetsi Ikayikidwa, mphamvu yamagetsi yamagetsi imathandizira chipangizocho "kudziwa" ngati chili pagawo lamagetsi otsika kapena malo okwera magetsi.
Ndinatenga Klein NCVT-1 kuzungulira nyumba yanga.Zimangozindikira ma voltages wamba.Kupambana kozindikira mphamvu kuchokera kumasoketi osavomerezeka ndi pafupifupi 75%.
