Kākoʻo ʻo Wirecutter i ka poʻe heluhelu.Ke kūʻai aku ʻoe ma o kahi loulou ma kā mākou pūnaewele, loaʻa paha iā mākou kahi komisina pili.aʻo hou mai
ʻO ka mea hōʻike uila pili ʻole ʻo ia ke ala wikiwiki a maʻalahi loa e nānā pono i ke ʻano ma nā uea, nā kumu, nā hoʻololi, a i ʻole nā ​​​​kukui kahiko i pau i ka hana.He mea paahana keia a kela me keia mea uila e lawe pu me ia.Ma hope o ke kamaʻilio ʻana me kahi mea uila uila me 20 mau makahiki o ka ʻike a me ka hoʻohana ʻana i ʻehiku mau hiʻohiʻona alakaʻi no ʻewalu mau mahina o ka hoʻāʻo ʻana, ʻike mākou ʻo Klein NCVT-3 ke koho maikaʻi loa.
Hiki iā Klein ke ʻike i ka uila maʻamau a me ka haʻahaʻa haʻahaʻa, a ua hoʻolako ʻia me kahi kukui uila-ke pio ke kukui, pono paha ʻoe i kahi mea hana maikaʻi.
Klein NCVT-3 he kŘkohu lua-voltage, no laila e ho'opa'a 'o ia i ka volta ma'amau (wiring i loko) a me ka volta ha'aha'a (e like me ka irrigation, doorbell, thermostat).ʻAʻole like me kekahi mau hiʻohiʻona a mākou i hoʻāʻo ai, hiki iā ia ke hoʻokaʻawale i ka ʻokoʻa ma waena o nā mea ʻelua.Hoʻopili pū kēia hiʻohiʻona me nā kumu hoʻoheheʻe ʻia i kēia manawa e koi ʻia e nā kikoʻī uila.ʻO nā mana ma ka NCVT-3 he intuitive a hōʻike maopopo.Ke hoʻāʻo ʻia i loko o kahi papa haʻihaʻi kaapuni piha i nā uwea ola a make, hiki ke heluhelu i nā uea make mai kahi mamao me ka hōʻike wahaheʻe ʻole i nā uwea ola mai kahi kokoke.Akā ʻo ka hiʻohiʻona maikaʻi loa ʻo ia kāna kukui kukui LED, hiki ke hana kūʻokoʻa i ka mea hōʻike uila.No nā mea hana i hoʻohana pinepine ʻia i loko o nā haʻahaʻa haʻahaʻa a i ʻole ke hana ʻana o nā kukui, he hiʻohiʻona lua kēia akā pono loa, a ʻo Klein wale nō ke kumu hoʻohālike a mākou i hoʻāʻo ai me kēia hiʻohiʻona.Wahi a ka hui, hiki i ka mea hana ke lawelawe i nā hāʻule a hiki i ka 6.5 kapuaʻi, ʻaʻole ia he hewa i ka noʻonoʻo ʻana he huahana uila maʻalahi.
ʻO kēia mea hōʻike uila lua e like me kā mākou koho i nā mea nui loa, akā ʻoi aku ka huhū o kekahi o kāna mau kikoʻī liʻiliʻi.
Inā ʻaʻole hiki iā ʻoe ke loaʻa iā Klein, makemake mākou i ka Milwaukee 2203-20 ʻike uila me ka LED.Kona kumukūʻai mea e pili ana i ka like, a like me Klein-ho'āʻo kūlana a me ka haʻahaʻa voltage, a me ka oluolu o ka hoʻohana.Akā, ʻaʻole ʻālohilohi ke kukui a ʻaʻole hiki ke hoʻohana wale ʻia me ka ʻole o ka mea hōʻike.Hoʻopuka pū ʻo ia i kahi beep nui loa a ʻaʻohe koho leo.
Hiki iā Klein ke ʻike i ka uila maʻamau a me ka haʻahaʻa haʻahaʻa, a ua hoʻolako ʻia me kahi kukui uila-ke pio ke kukui, pono paha ʻoe i kahi mea hana maikaʻi.
ʻO kēia mea hōʻike uila lua e like me kā mākou koho i nā mea nui loa, akā ʻoi aku ka huhū o kekahi o kāna mau kikoʻī liʻiliʻi.
Ua kākau a loiloi au i nā mea hana mai ka makahiki 2007, a ua paʻi ʻia nā ʻatikala ma Fine Homebuilding, This Old House, Popular Science, Popular Mechanics and Tools of the Trade.Ua hana nō hoʻi au ma ke ʻano he kamanā, foreman a me ka luna hoʻokele pūnaewele no 10 mau makahiki, e hana ana ma nā papahana hale noho miliona miliona.I ka makahiki 2011, ua wāwahi au i koʻu hale mahiʻai he 100 mau makahiki, he ʻōnaehana uila hou.
No ka ʻike hou aku e pili ana i nā mea hōʻike uila pili ʻole, ua kamaʻilio wau i ka poʻe e hoʻohana nei iā lākou i kēlā me kēia lā: Mark Tierney o Tierney Electrical, Hopkinton, Massachusetts.ʻO Tierney he 20 mau makahiki o ka ʻike a ua holo ʻo ia i kāna ʻoihana ponoʻī mai 2010.
ʻO ka mea hōʻike uila pili ʻole e pono ke kokoke e ʻike i ke ʻano o ka uea a i ʻole ke kumu.1 ʻO ia ka nui a me ke ʻano o kahi momona ʻoi.Hana ʻia ka ʻike ma ka piko o ka probe.I nā manawa he nui, ua hoʻolālā ʻia ka piko probe e pana ʻia i kahi puka.No ka mea ʻaʻole ʻoluʻolu nā haʻalulu uila i ka maikaʻi a me ka pōʻino loa i ka maikaʻi loa, pono kēia mea hana no nā hana uila māmā loa, e like me ka hoʻoponopono ʻana i kahi thermostat a i ʻole ke kau ʻana i kahi hoʻololi dimmer.
ʻOiaʻiʻo, he mea hana maikaʻi loa ia no nā mea uila DIY, akā hiki i nā poʻe me ka ʻole uila ke pōmaikaʻi mai ka loaʻa ʻana o hoʻokahi.Hoʻohana maʻamau iaʻu e like me ka pae mua o ka hoʻoponopono pilikia ma mua o ke kāhea ʻana i kahi mea uila ʻoihana.
Hiki i ka mea hōʻike hoʻopili ʻole ke kōkua i ka palapala ʻana i kāu ʻōnaehana uila.ʻAʻole au i noho ma kekahi hale kokoke i ka papa kuhikuhi pololei.Inā he hale kahiko a hale paha kāu, ua kuhi hewa paha kāu papa uila.ʻO ka hoʻoponopono ʻana i kēia pilikia he kaʻina hana manawa, akā hiki nō.E hoʻopau i nā mea hoʻomaha kaapuni a pau koe hoʻokahi, a laila e nānā i ka hana a puni ka hale.Ke noʻonoʻo ʻoe, e lepili i ka mea hoʻomaha kaapuni a neʻe i ka mea aʻe.
Hoʻopaʻa wale ka hapa nui o nā mea hōʻike hoʻopili ʻole i nā voltage maʻamau.Ma hope o ka heluhelu ʻana e pili ana i ke kumuhana, ua hoʻoholo mākou e ʻoi aku ka maikaʻi o ka mea hōʻike uila lua-lua no nā pahu hāmeʻa home.No ka uila maʻamau, hiki ke hana maʻamau, a aia ka pōmaikaʻi hou o ka ʻike uila haʻahaʻa, pono ia no nā bele puka, thermostats, kekahi mau lako AV, irrigation a me kekahi mau kukui ʻāina.ʻO nā kumukūʻai o nā hiʻohiʻona lua-voltage a me hoʻokahi-voltage ka nui ma waena o US $ 15 a me US $ 25, no laila, ua kūpono nā mea hana lua-lua i mea hana hoʻokahi no ka poʻeʻoihanaʻole;ʻoi aku ka nui o ka loaʻa ʻana o ka hiki a me ka hoʻohana ʻole ʻana ma mua o ka pono a ʻaʻole hoʻohana.maikaʻi loa.
Ke hoʻoholo nei i nā hiʻohiʻona e hoʻāʻo ai, ua aʻo mākou i nā huahana Amazon, Home Depot, a me Lowes.Ua ʻimi pū mākou i nā mea hana hana mana kaulana.Mai ia manawa, ua hōʻemi mākou i ka papa inoa i ʻehiku.
Ua hana mākou i kekahi mau hoʻāʻo e hoʻoholo i ka pono a me ka naʻau o kēlā me kēia mea hoʻāʻo.ʻO ka mua, ua hoʻopau au i kahi mea hoʻomaha kaapuni ma ka pahu uila a hoʻāʻo e ʻike i kahi o nā uea 35 i puka mai i waho i haki.Ma hope o kēlā, ua lawe au i kahi uwea make e ʻike inā hiki iaʻu ke lawe i ka mea hana kokoke i ka uea ola a loaʻa mau ka mea hōʻike e heluhelu maikaʻi ʻole.Ma waho aʻe o kēia mau hoʻāʻo ʻana, ua hoʻohana pū wau i ka mea hōʻike e hoʻopili i kekahi mau kumu a hoʻokomo i kekahi mau hoʻololi dimmer, nā kīʻaha kuke, nā pā kaupaku a me kekahi mau chandelier.
Hiki iā Klein ke ʻike i ka uila maʻamau a me ka haʻahaʻa haʻahaʻa, a ua hoʻolako ʻia me kahi kukui uila-ke pio ke kukui, pono paha ʻoe i kahi mea hana maikaʻi.
Ma hope o ka noiʻi ʻana i nā kumuhana, kamaʻilio me nā mea uila, a me ka hoʻolilo ʻana i nā hola e hoʻāʻo ai i ʻehiku mau kumu hoʻohālike, paipai mākou iā Klein NCVT-3.Loaʻa i ka NCVT-3 kahi kukui hōʻike intuitive, kahi pihi on / off nani a me kahi LED onboard e hana like me ke kukui uila liʻiliʻi.He hiʻohiʻona maikaʻi kēia, no ka mea, ke nānā ʻoe i ka volta uea, ʻaʻole pono ke kukui.He kūpono hoʻi ia me ke kumu hoʻoheheʻe ʻia e koi ʻia e ke code o kēia manawa.Loaʻa iā NCVT-3 kahi hōʻailona ola pākaukau a me ke kino paʻa e pale i kāna mau mea uila maʻalahi mai nā hāʻule a hiki i 6½ kapuaʻi.
ʻO ka mea nui loa, maʻalahi loa ka hoʻohana ʻana o NCVT-3.ʻO ia kahi mea hana ʻelua, no laila hiki iā ia ke ʻike i nā voltage maʻamau (nā kumu, nā wili maʻamau) a me nā haʻahaʻa haʻahaʻa (bele puka, thermostat, irrigation wiring).ʻO ka hapa nui o nā mea hoʻāʻo e ʻike wale i nā voltage maʻamau.ʻAʻole e like me ka hapa nui o nā hiʻohiʻona pālua ʻelua, hiki iā ia ke hoʻololi ma waena o nā pae me ka ʻole o ka hoʻohana ʻana i kahi kelepona paʻakikī.Hōʻike ka pakuhi pahu LED ma ka ʻaoʻao o ka hāmeʻa i ka volta āu e hana nei.Hoʻomālamalama ka ʻike uila haʻahaʻa i nā kukui ʻalani ʻelua ma lalo, a hoʻomālamalama ka uila maʻamau i hoʻokahi a ʻoi aku paha o nā kukui ʻulaʻula ʻekolu ma luna.Nui nā hui e kūʻai aku i nā mea ʻike kiʻekiʻe a me nā haʻahaʻa haʻahaʻa, akā no ka poʻe ʻoihana ʻole, kūpono ke kau ʻana iā lākou i hoʻokahi mea hana, ʻoiai inā maʻalahi ka hana e like me Klein.
I loko o koʻu haʻahaʻa haʻahaʻa, ua hoʻopaʻa ʻia nā uea i ke kaupaku ma luna o nā kukui fluorescent, no laila inā ʻaʻa nā kukui, paʻakikī ke mālama ʻana i nā uea.ʻO nā hiʻohiʻona ʻelua me nā kukui uila, ʻo NCVT-3 wale nō ka mea hiki ke hana kūʻokoʻa i ka hana hoʻāʻo, maikaʻi loa.
ʻO ke kukui uila he mea koʻikoʻi o NCVT-3.I loko o koʻu hale haʻahaʻa, ua hoʻopaʻa ʻia nā uea i ke kaupaku ma luna o nā kukui fluorescent, no laila inā ʻaʻa nā kukui, paʻakikī ke mālama ʻana i nā uea.ʻO nā hiʻohiʻona ʻelua me nā kukui uila, ʻo NCVT-3 wale nō ka mea hiki ke hana kūʻokoʻa i ka hana hoʻāʻo, maikaʻi loa.Ke hoʻā ʻia ka mea hoʻāʻo, e loaʻa ke ʻano o nā beeps a me nā kukui uila.Inā makemake wale ʻoe e hoʻohana i ke kukui uila, maikaʻi e hiki ke pale aku.ʻO kā mākou koho hoʻokūkū, ʻo ka Milwaukee 2203-20 voltage detector me LED he hana kukui uila, akā e hoʻomālamalama wale ʻia ke hoʻāla ʻia ka mea hōʻike, no laila, pono ʻoe e hoʻolohe i ka beeping, ʻaʻohe ala ʻē aʻe. inā ʻoe i loko o kahi lumi mālamalama e hoʻopau i ke kukui i ka wā e hana ai ma ke kūlanakauhale.ʻOi aku ka mālamalama o ka NCVT-3 LED ma mua o Milwaukee.
ʻO NCVT-3 ka manaʻo paʻa loa.Wahi a ka mea hana, hiki iā ia ke pale i kahi hāʻule 6.5-foot, no laila inā ʻike ʻoe i kahi hāʻule, e hāʻawi kēia kumu hoʻohālike iā ʻoe i kahi manawa e ola ai.Eia kekahi, ua hoʻopaʻa ʻia nā kī, a ua hoʻopaʻa ʻia ke poʻi o ke keʻena pākaukau, no laila hiki i ka NCVT-3 ke kū i kahi ua liʻiliʻi a me ka haʻahaʻa.Loaʻa iā Klein kahi wikiō e pili ana i ka mea hana, a me he mea lā aia ma lalo o kahi pai kulu.
I ko mākou nīnau ʻana i ka mea uila ʻo Mark Tierney inā makemake ʻo ia i kekahi mea hana i ka mea nona ka hale, haʻi ʻo ia iā mākou "ʻo Klein ka mea hilinaʻi loa."Makemake ʻo ia i nā hiʻohiʻona me nā LED.Ua ʻōlelo ʻo ia no nā mea hale, "e loaʻa iā lākou ʻelua mau hiʻohiʻona nui i hoʻokahi mea hana."
E pili ana i ke ola pākaukau, ua ʻōlelo ʻo Klein e hāʻawi ʻelua mau ʻāpana AAA i 15 mau hola o ka hoʻohana mau ʻana i ka hoʻāʻo a me 6 mau hola o ka hoʻohana mau ʻana i ke kukui uila.Ua lawa kēia no nā mea hoʻohana i kekahi manawa, e like me kā mākou i ʻōlelo ai, maikaʻi ka loaʻa ʻana o kahi hōʻailona pākaukau i ʻike ʻoe i ka wā e haʻahaʻa ai.
ʻAʻole mākou wale nō ka mea makemake i ka NCVT-3.Ua ʻōlelo ʻo Clint DeBoer, nāna i kākau ma ProToolReviews, ʻo ka hāmeʻa "ʻOiai inā hana ʻoe i ka hana uila i kekahi manawa, hiki iā ʻoe ke maʻalahi."Ua hoʻopau ʻo ia: "He mea hana maikaʻi kēia i hiki ke hana i ka mea pono a hana.Maikaʻi loa.E koho i hoʻokahi.ʻAʻole ʻoe e mihi.
Ua loaʻa pū i ka NCVT-3 nā loiloi maikaʻi ma Amazon a me Home Depot.ʻO ka hapa nui o nā nūhou maikaʻi ʻole ma Amazon mai ka poʻe makemake i ka hāmeʻa akā ua hōʻino ʻia ʻaʻole hiki ke hoʻopili ʻia i ke kumu.E like me ka mea i ʻōlelo ʻia ma luna nei, ʻaʻole pilikia kēia no ka mea hiki iā ia ke ʻike i ke ʻano o kēia manawa a hōʻike wale iā ia ma ke ʻano he haʻahaʻa haʻahaʻa (a hoʻohālikelike ʻia me ka socket tamper-proof i koi ʻia e ke code).No ka hōʻoia maoli i ka volta maʻamau ma ke kumu, maʻalahi ka wehe ʻana i ka uhi a kau i ka piko o ka mea hana ma ka ʻaoʻao o ke kumu kahi i loaʻa ai nā uea.
He kū hoʻokahi ʻo NCVT-3 no ka mea ʻaʻole hiki ke hoʻopili ʻia i kahi kumu.I ka nānā mua ʻana, he pilikia kēia, no ka mea, hiki i ka hapa nui o nā mea hōʻike hoʻopili ʻole ke heluhelu i ka mana mai ke kumu ma ka hoʻokomo ʻana i loko o kahi puka.ʻO ka ʻoiaʻiʻo, no ka mea hiki iā ia ke heluhelu i nā haʻahaʻa haʻahaʻa, hiki i ka NCVT-3 ke huki i kēia manawa mai waho o ke kumu, he mea koʻikoʻi ia i ka wā e pili ana i nā kumu hoʻoheheʻe ʻia i koi ʻia e nā code uila.No ka hoʻokomo ʻana i ka plug i loko o kekahi o nā kumu, pono e hoʻopili ʻia ke kaomi like i nā puka pine ʻelua (he pilikia palekana kēia no nā keiki).Me kēia mau kumu, ʻaʻole hana mau ka mea hōʻike uila pili ʻole no ka mea hiki iā ia ke heluhelu i nā voltage maʻamau.E like me kā Bruce Kuhn, ka luna huahana o ka hoʻomohala ʻana i nā huahana, ka hoʻāʻo a me ke ana ʻana ma Klein, i haʻi mai iā mākou, "Inā ʻoe e hana i kahi mea hoʻāʻo e ʻike pono i ka uila ma waho o kahi kumu hoʻoheheʻe ʻia, a laila aia i loko o ka lehulehu. pahu uila.He uwea wela.”2 No ka mea, ua hoʻolālā ʻia ʻo NCVT-3 e ʻike i ka uila maʻamau a me ka haʻahaʻa haʻahaʻa, i ka wā e waiho ʻia ai i ka wehe ʻana o kahi kumu hoʻoheheʻe ola, e ʻohi ʻo ia i ka volta maʻamau, akā mai kahi mamao, ʻike ʻia he haʻahaʻa Voltage, e hōʻoia mau i ke ola o ke kumu.
Aia nā pihi mana ma ka ʻaoʻao o NCVT-3, a Tierney i ʻōlelo mai iā mākou e hoʻolohe.Ua ʻōlelo ʻo ia he mea maʻalahi nā hiʻohiʻona me nā pihi ʻaoʻao ke waiho ʻia i loko o kahi ʻeke, ʻaʻole ia he mea hoʻonāukiuki wale nō, akā e hoʻolalelale i ka hoʻohana ʻana i ka pākaukau.Hoʻokahi ʻokoʻa mai ka NCVT-3 ʻo ia ka ʻili o nā pihi me ka ʻili;ʻO ka hapa nui o nā pihi e like me kēia e puka mai ana mai ka ʻaoʻao o ka hāmeʻa a hiki ke hoʻohana maʻalahi ʻia.Ua hoʻohana au i ka NCVT-3 i loko o kaʻu ʻeke no hoʻokahi lā, ʻaʻole i wehe ʻia.
ʻO kēia mea hōʻike uila lua e like me kā mākou koho i nā mea nui loa, akā ʻoi aku ka huhū o kekahi o kāna mau kikoʻī liʻiliʻi.
Inā ʻaʻole i loaʻa ʻo Klein, paipai mākou i ka Milwaukee 2203-20 ʻike uila me ka LED.He nui nā hana like me Klein NCVT-3, akā ʻaʻole like ke kukui uila a ʻaʻole hiki ke hoʻohana kūʻokoʻa i ka mea hōʻike.Hoʻopuka pū ia i kahi kani kani nui (ʻaʻohe koho leo ʻole).He mea maikaʻi paha kēia ma kahi kahua hana walaʻau, akā ma hope o koʻu hoʻolilo ʻana i nā minuke 45 i ka nānā ʻana i nā uea i loko o ka haʻahaʻa haʻahaʻa, ua lawa ka leo e hoʻolilo iaʻu i mea pupule.
Eia nō naʻe, hiki i Milwaukee ke ʻike i ka haʻahaʻa haʻahaʻa a me ka uila maʻamau, ʻaʻohe hoʻololi lima ma waena o lākou, no laila ua maʻalahi ka hoʻohana ʻana e like me NCVT-3.
I ka makahiki 2019, ua ʻike mākou ua loaʻa iā Klein ka NCVT-4IR.ʻIke like ia me kā mākou koho, akā loaʻa pū kekahi hana thermometer infrared.Manaʻo mākou ʻaʻole kūpono kēia i ke kumukūʻai hoʻonui no ka hoʻohana maʻamau o ka home.
Ua ʻike pū mākou i nā hiʻohiʻona mai nā hui e like me Meterk, ToHayie, Taiss, a me SOCLL.He mau mea hana maʻamau kēia mai nā ʻoihana liʻiliʻi ʻike.Manaʻo mākou ʻoi aku ka palekana o ka ʻōlelo ʻana i nā mea hoʻāʻo mai nā mea hana hana diagnostic uila i hōʻoia ʻia.
Ua hoʻāʻo mākou iā Klein NCVT-2, he mea like loa me NCVT-3.He kŘkohu lua ia e hiki ke 'ike 'akomi ma waena o na laula elua, aka, aole he LED;haʻaheo ka pihi on/off (no laila e wehe ʻia i loko o ka ʻeke);a ʻaʻole i loaʻa i ka hihia kēlā manaʻo paʻa.
Ua ʻike pū mākou iā Greenlee GT-16 a me Sperry VD6505 e hoʻohana i ke kelepona e koho i ka ʻike ma waena o ka haʻahaʻa haʻahaʻa a me ka uila maʻamau.I ka wā o kā mākou hoʻāʻo ʻana, ʻike mākou i ka nui o nā uea ma ia wahi, e loaʻa i kēia mau hiʻohiʻona nā hōʻailona mai nā uea ʻē aʻe, he mea paʻakikī iā mākou ke ʻike i ka wā e hoʻemi ʻia ai ka naʻau e ʻike wale i nā uea a mākou e makemake ai.He mea paʻakikī ke aʻo ʻana i nā mea hoʻopunipuni o nā dial sensitivity, a makemake i ka interface maʻalahi o Milwaukee a me Kleins.
Loaʻa iā Greenlee TR-12A kahi hoʻolālā ʻelua-pin no nā kumu hoʻoheheʻe ʻia, akā hiki iā ia ke heluhelu i nā voltage maʻamau ma mua o nā haʻahaʻa haʻahaʻa, no laila ke manaʻo nei mākou ʻoi aku ka maikaʻi o ka NCVT-3.
ʻIke wale ʻo Klein NCVT-1 i ka uila maʻamau.Ua loaʻa iaʻu kekahi no nā makahiki he nui a ua ʻike mau wau he pololei a hilinaʻi hoʻi, akā kūpono ke kiʻi ʻana i kahi kumu hoʻohālike hiki ke ʻike i nā haʻahaʻa haʻahaʻa.
