Voltage Tester: mathupha. Uyini umhloli voltage ukuthenga Amathiphu

Ukusebenza kagesi, cabling futhi bakha imizila edingekayo yokwenza imikhiqizo ekhona buyingozi ukuze uthole ukulimala kagesi. Isizathu salokhu ilula - ukunyakaza iqondiswe izinhlayiya icala umqhubi ingabonakali ngeso lenyama. Ngakho-ke, phakathi nokufaka, ukwenziwa nokugcinwa kwezinto zisesimweni imishini kagesi kufanele sisetshenziswe ukuhlola umhloli voltage Okwazi okungenani nje ukukhombisa khona engaba, ngisho ngaphandle kokukala inani layo langempela.

isidingo esibalulekile

Voltage Tester - idivayisi ephathekayo kagesi okuhlose ibonisa ezingaba ezindaweni conductive. Supply ugesi akubona bonke izintambo ayingozi uma icindezelwa. Yamanje elwa lezo isigaba samanje, kodwa kuqanda phansi wire ivikeleke. Nokho, kukhona ukubhuka.

Ukuze siqonde ukuthi kungadingeka ku umhloli ikhaya yamandla aphindeke kabili, indlela elula ukunikeza eziningi izibonelo. Cabanga ukuthi kwakunesidingo ku grinder (grinder), lolo ngesikhathi sokuhlwanyelwa wanikeza umakhelwane. asetshenziswa Namanje onobuhle, okuyinto izindlu senziwa metal. Indlela hlola ukuthi izifunda yangaphakathi engazange ithinteke, kanti igobolondo akukho ukungezwani? Ukusebenza ithuluzi enjalo, ngemva kokuba ihlolwe - impela gembula. Noma, ngokwesibonelo, kudingeka ushintshe isibani e isibani, ingilazi isibani kuwa, futhi kuphela plinth lahlala igobolondo. Believe ngogesi kokwenza wiring, inkinobho iphula ngempela umqhubi isigaba kanye non-zero basontane cap ngesibindi? Kuyangabazeka! Izibonelo ezinjalo eziningi. Nge siqu voltage umhloli yayo, ungahlala ngokushesha hlola isayithi yokumiswa. Ngaphezu kwalokho, onobuhle eziyinkimbinkimbi uvumele yokukala Inani lamanje.

izici eziyisisekelo

Ukuze uqinisekise khona engaba (isigaba), asikho isidingo ukuchitha imali ukuthenga izimpahla ezibizayo. The elula voltage umhloli - ukufakwa kokumqoka kuphela inkomba. Ngaphakathi umzimba wayo esobala has nesibani esincane ukuthi ikhanyisa lapho uthinta Udosi ezindaweni ngaphansi ezingaba khona.

Njengoba umhloli ukuhlola voltage? Ohlangothini engenhla Kwe-dielectric Heating isibambo has a metal okhethekile "ngisho nesenti. ' Ukuhlola esigabeni uchungechunge kumele kube usebenzisa ukufakwa kokumqoka kuphela uthinte imikhondo ukuhlolwa, futhi umunwe - ". Kopecks emihlanu" a Ngokusobala sting lapho asikwazi wathinta. Uma esigabeni likhona, ukukhanya esikhanyisa ngaphakathi ukufakwa kokumqoka kuphela. igama wesibili isikudilayiva - iphenya. Ziklanyelwe kuze 250 V for voltages

It is hhayi Kunconywa ukuthenga imodeli eshibhe, njengoba kwaba njalo endabeni ka ukuwohloka we Resistor yangaphakathi noma amaphutha isikimu ungathola shock ngogesi. izixazululo Okuningi eziphambili angadingi ukuthintana ngqo ingxenye wesifunda. Sting a ukufakwa kokumqoka kuphela, udinga nje ukuba uchithe imali engaphezu umqhubi. Yakhelwe kuze kufinyelele 600 V for voltages Ngaphezu kwalokho, amanye amamodeli anemisila isibonisi ukuthi ubonisa Inani lamanje.

Kukhona ukulungiswa angadingi touch of a umunwe kuya "kopecks ezinhlanu." Ungakwazi ngaphandle kwezinkinga ukuthenga umhloli voltage. Imiyalelo ngokuthi kufanele ufunde. Lokhu kusindisa hhayi kuphela iyunithi ekulimaleni, kodwa futhi uyobavikela umuntu.

ukufakwa kokumqoka kuphela ezimbili

Ngesikhathi esifanayo amathuluzi ngenhla kancane kakhulu ezikhethekile. Uma ufuna, isibonelo, ukwenza umsebenzi elula - ukwehlukaniswa izigaba, kuyize ngenxa khona isigxobo eyodwa kuphela. Kulokhu, kufanele sinake umhloli okuthuthukile - pointer double voltage low. Ikhipha ke ingafaniswa isikudilayiva amabili, ucingo uxhumano. Umkhawulo voltage kuvunyelwe 1 kV. Inani - ruble 100.

Cabanga indlela yokukala umhloli voltage alesi sigaba. Sting-electrode omunye isidingo uthinte wesifunda ngaphansi kovivinyo indawo, kanye nezinye - ". Umhlaba" kuya Lokhu kungaba noma yimuphi umqhubi phansi ukuze ezingaba yingozi akusho egeleza idivayisi. Uma isibani ikhanyisa ngaphakathi emzimbeni, lokhu kuyosho ukuthi kukhona imimoya endaweni. Uma udinga ukuba ukwehlukaniswa izigaba kudingeka kuthinte Uphenyo omunye komunye isigaba umqhubi, kanye nezinye - omunye. Uma esigabeni phezu izintambo of the gama elifanayo ke akukho okubonisa. onobuhle Lula ukukhombisa Iqiniso khona isigaba futhi nzima futhi aqukethe omunye LED izibambo amaningi, le luminescence ongatholakala ukunquma ukubaluleka voltage.

inkomba

Ekilasini elilandelayo amadivayisi abanjalo bangabaphostoli voltage izinkomba. Imodeli esaziwa kakhulu "Imininingwane" umkhiqizi Ukraine. izindleko iqala ruble 400. Ikhipha lezi abahloli ngalokwanele zifane ukufakwa kokumqoka kuphela kabili, kodwa babe izici ezithuthukile. Ikakhulukazi, angasetshenziswa ukuze sithole ukuthi isigaba ukulinganisa cishe ezingeni voltage kusukela ekushayweni LED, hlola ubuqotho umqhubi. Ngaphakathi epholisayo itholakala, okumele oyi-icala by touch iphenya 220 / 380V amasekhondi 20-30.

Indlela ukuthola wire bukhoma

Cabanga indlela umhloli ukuhlola voltage. Omunye iphenya zedivayisi udinga uthinte zihlolwe indawo ukufakwa, futhi isithupha - PH kuya electrode emzimbeni. Uma LED elihambisana ikhanyisa ke umqhubi is nginomdlandla. Nokho, kukhona caveat, okuyinto kahle kwaziwe abantu abakwaziyo ukusebenza voltage umhloli yalolu hlobo. Ihlala e yokuthi isigaba yokuhlola ngokusebenzisa PH akulona njalo ilungile, njengalokho ubufakazi kungayithonya nokugxambukela eduze babashayeli zamanje aphethe umqondo. Ukuze sicacise, kukhona izintambo ezimbili eduze, enye yazo akukhuthalele kanye nezinye akukhuthalele. Uma ungazi kanjani ukusebenza voltage umhloli ngokuningiliziwe, kokuhlola kokubili babashayeli ngokuthinta nabo PH electrode kuvela ukuthi ngokuvumelana okubonisa bobabili isigaba. Nokho, akuyona. Vele uyeke nginomdlandla eyenga amandla electromotive ngaphansi isenzo emkhakheni kagesi. It ifinyelela ezimbalwa kuphela amashumi volts, kodwa kunqunywa kudivayisi futhi akubonisi ngomsebenzi wayo. Ezimweni ezinjalo, uma ungaqiniseki, okudingeka ukwenze ngenye: touch elilodwa Uphenyo endaweni kokuba abuyekezwa, kanye nezinye - iphuzu eyaziwa lusekelwe. Ephambi kwezinduna isigaba umqhubi LED ukukhanyisa futhi zibonisa ukubaluleka silinganisiwe 220 V By endleleni, ababenelungelo lokungena voltage ezintathu okhombisa, hlola indawo unga ngokuthinta nje kuphela "umhlaba", kodwa futhi ukuba omunye babashayeli isigaba. Lokho kufana ukuqaliswa isinyathelo esiqhubekayo. Endabeni khona voltage engxenyeni thinta isigaba heteronymic kuzoholela ekushayweni we LED 380 V

Semfene ka pointer umhloli

Isenzo sokunqophisa uthi wamanje egeleza ngedivayisi wesifunda uma uhlola umthamo 220 akuyona ezingaphezu kwezingu-10 ma. Okusho ukuthi, uma uthinta omunye iphenya esizeni sokuphehla amandla, engaphansi voltage, le ammeter ixhunywe kwesinye uphenyo, okungenhla sizobonisa Inani lamanje. Kwakucatshangwa ukuthi lokhu kuyinto ukubaluleka eziyingozi (100 MA - ebulalayo), ngokomthetho touch of a isandla kungenzeka, kodwa uma nje busebenze yangaphakathi zedivayisi zilungile.

Ukuqalisa nge "contact"

Zonke izixazululo lapho amayunithi ezimbili oxhumene by ucingo, luyingozi. Omunye zinezithiyo ezithile - kungenzeka zilimaza umqhubi yokuxhuma ngesikhathi ebonakalayo igobolondo ubuqotho. Ngakho-ke, uma uhlola isigaba ngokusebenzisa PH Kunconywa Uphenyo block on lapho electrode asebenzayo ibekwe. Kulokhu, LED izosebenza, ngisho noma wire lilimele. Nokho, ngaphambi kokwenza izilinganiso Udinga ukuxhuma idivayisi kunethiwekhi futhi uyibambe 20 - phakathi nalesi sikhathi icala kwangaphakathi namandla umthombo. Khona-ke kudingeka ukuba uxhume nomunye iphenya. Uma wire, LED lights up "ukuhlolwa."

ithuluzi jikelele

Ngaphezu zonke lezi amadivaysi, kukhona olunye uhlobo - multimeters. Mhlawumbe lena esiphelele kunazo voltage umhloli. Indlela ukuyisebenzisa, sizokwenza manje ukuchaza. Izindleko models ezingabizi kakhulu iqala engama-ruble angu-300. Umsebenzi ezichazwe kuleli bhukwana elithi okufanele kuyatholakala. Uma sikhuluma kokuhlola voltage, omunye wire Kumele uxhumeke port COM, elinye - ukuba V Bese, usetha inkinobho ukuze 750 AC (kushintshana uhlobo zamanje, kumkhawulo 750 V) imodi bese uthinta iphenya ukuba "umhlaba" futhi endaweni kokuba abuyekezwa.

okutholakele

Ngakho, akunakwenzeka ukunikeza izincomo ecacile kukhethwa yomculo. Konke kuncike uhla imisebenzi kuhlehlwe ukuba kubhekwane. Uma kukhona imali eyengeziwe kungaba kuhle kakhulu ukuba uthenga multimeter jikelele.
