Me pēhea te ki te whiriwhiri i te multimeter mō te kāinga me te motokā

Tae noa te tahi tau ahuru matahiti i ma'iri a'e, te ariki, nei i ki te mahi ki te hiko, e kore e taea e whakaaro te ora, kahore taua whakaaro whai hua rite ohmmeter, ine ngaohiko me te iahiko. I teie mahana, mai ratou ki te whakakapi i te mita. Ko te whakamutunga, ko te he pūrere te ao mō te whakamatautau i te whānui o ngā tawhā hiko me whatunga momo. Kia kitea tatou i roto i pehea ki te whiriwhiri i te multimeter mō te kāinga me te motokā, whakaaro te whakaaro o tenei kāwai o ngā pūrere, ratou taumahinga.

He aha te mea multimeter whanganga?

Ka taea te whakamatauria te whakamahi i tenei pūrere:

• DC a AC ngaohiko;
• te puritanga;
• te pāmahana i roto i ngā wāhanga rerekē o te ara iahiko hiko;
• transistors mahi me te p;
• coils hiko;
• DC a AC nāianei.

momo multimeters

I mua i fakakaukau'i atu pehea ki te whiriwhiri i te multimeter pai, e hiahia ana koe ki te whakaaro i te momo o taua whakaaro. I tēnei wā e wātea ana rangatira hiko me ngā pūrere tairitenga. A feruri i to ratou āhuatanga i roto i te raupapa.

I roto i ngā pūrere tairitenga e whakaaturia inenga katoa i runga i te pae whakairoiro mā te neke te pere ki te faatura ki wehenga. Kei te reira i te whakatika, ia o nei hāngai ki te tohu ngā. Ko te drawback matua o tenei parau tumu - te hē whanaunga o te whakaaturanga. Ahakoa i roto i te kounga pere tairitenga multimeter paku fluctuates taha, e arata'i ki etahi raraunga distortion. Noatia, ki te hiahia te ariki whakatika uara anake noa, a ka uru te pūrere taua ki reira. I roto i te whānui, he ngā tawhito pūrere tairitenga, na kua whakamahia i tenei ra e tino onge.

Miharo e pā ana ki te pehea, ki te whiriwhiri i te multimeter, kaimahi mātanga whakarongo matua i runga i te whakaaro hiko. i hanga raraunga katoa te i runga i te whakaaturanga mamati. He tika, me te ngāwari ki te matau pānuitanga repeatable. pūrere hiko i roto i te taumahinga whanui āhuatanga tino pai.

I aha ngā kia utu koe whakarongo ki ka hoko i te multimeter?

He he maha o ngā āhuatanga tautuhi e kia kia whakaaro ka tīpako i te pūrere whanganga :

• whānui o ngā tohu;
• hapa;
• inenga moka;
• pūrere Powered;
• te maha o ngā whakaaturanga.

Next, whakaaro me pehea ki te whiriwhiri i te multimeter, e arotahi ana ki enei tawhā.

Ko te whānuitanga o ngā tohu

Ko te āhuatanga hua whakaatu i te uara rohe mōrahi me te mōkito o te tawhā e kia ana te ruri. Tīpakonga multimeter, timata mai i te whānuitanga o ngā tohu, i runga i te hōkai tikanga o te pūrere rānei. Ki te whakamahere koe ki te whakamahi i te reira no te mahi i roto i nga tikanga o te ora, i roto i tenei take nui ki te aukati i te kōwhiringa i runga i te pūrere ki te whānuitanga āhua tano. Ko ngā tono ahumahi, i reira he pai ki te hiahia te multimeter ki te taea ngā whānui o ia tawhā e hiahiatia ana.

hapa

e kore e ara te nuinga o ngā pūrere hiko-kounga tiketike tukua ki te tiki inenga tino pau. mau tonu te hapa iti, whakaaro motuhake e taea rerekē i roto i te whānui i 0.02 ki te 3%. Te whakatau i pehea ki te whiriwhiri i te pourewa-multimeter, kia hoatu nui faufaa ki te ine ngā.

Ki te hokona te pūrere ruri te hoki aroturuki te hikohiko mahi, e tūtohu ana ki te whakarongo ki tauira ki iti rawa hapa. Ko te whakamahi kāinga o te ia hei whakamatau, i reira ka uru te pūrere ki etahi ine i te tawhā mahi tūturu.

kaha

te, pehea tika pānuitanga e taea te tāruatia te ngako o te tawhā i runga i-mata whanganga pūrere. Hei tauira, kua te nuinga o te multimeter rā bit-2.5 whakaaturanga mamati, whakaatu uara nei tika tae haurau wahi ira. I te wa ano, i te bit-3.5 pūrere uara putanga i runga i te mata ki te haumano.

E ngana ana ki te mārama me pēhea ki te whiriwhiri i te mita, e hāngai ana i runga i nga tawhā o te rere, kia utua te uara o te hapa ngā. Ki te he te reira faahiahia, e kore e ara te taea o haumano o uara i runga i whakaaturanga ka mea faufaa, no te mea ka hē te mōhiohio.

kai

Multimeters he whakaaro tu-anake. Te nuinga o enei mahi i pūhiko tikanga. Ko te tino nui ki te whakarite mahi mō te wā roa-o te ia hei whakamatau, ki te tika, te mahi inenga whare te supply mana. Heoi, i roto i te take o te mahi o te mita mō te whakamahi ahumahi e kore ko e nui. I roto i tenei take, ko te mea e tika ana ki te aukati i te kōwhiringa i runga i te ia hei whakamatau, rite rawa nei te ki te pākahiko capacitive.

Tau o ngā whakaaturanga

Kia whai whakaaro ki te whakaaturanga o ngā āhuatanga kia te rangatira, e te hunga i roto i te rapu o te pourewa hoki te whakamahi i roto i tētahi taiao ahumahi mō te mahi ki te Avionics matatini ranei. Tīpako multimeter waka mō te ine i roto i te taiao motu mua taea e te whakaatu kotahi. He mata mamati maha ka watea mō ngaio e te hunga i runga i hopoi'a whai ki te kawe i te rota katoa o inenga rerekē.

Arotake o tauira rongonui

Me pēhea te ki te whiriwhiri i te multimeter mō motokā me te kāinga? He he torutoru tauira noa o rawa mahi, ngāwari-ki-te whakamahi testers e he tika ana mo enei take:

1. ADD8055 - Tauira multimeter i āta hangaia mō te ine i te mahi o ngā pākahiko. Ki te taea e te reira te aroturuki hoki i te tawhā whakahaere o pūkaha tīmatatanga makariri, riro raraunga i te ngā wahi o iahiko.
2. ADD280 - he pūrere whakamahia ki te whakatau poraka o kōhao mura i roto i engines diesel. Operation o te pūrere hanga taea reira ki te kitea hape i roto i sparking i taua pūnaha.
3. ADD3055 - hei whakamatau tātaritanga mo te ako o ngā wae mana pūoko, ngā pūnaha hiko o waka. Ko te horapa whānui kua riro tenei tauira multimeter pokapū ratonga mō te tukunga waka.
4. ADD8630 - mō te aro mātai o te huru hangarau o tīmata pereoo, generators, pākahiko. Tenei ia hei whakamatau Kei roto he wae mahi i roto i te pūreretā, mā i te reira taea ki te whakaatu i te mōhiohio i runga i te pepa.
5. ADD91 - pūnaha ruri multifunctional Kei te whānui e whakamahia e electricians me rehe motokā. Kei roto te reira i te whakaatu backlit me he taea ki te whakatau i tohu e whakaputa uri ngā pūoko.

tīwhiri āwhina

Hei whakatau pae hopea aha ki te whiriwhiri mo te mita o te motokā, me te whakatinanatanga o ngā mahi whare tango kia ki pūkete e rave rahi tūtohutanga.

A, no te huihui i te nuinga tūturu o testers hiko whakamahia maramara pono. Na reira, whakarongo motuhake ki kore e te pūrere whakakī hiahiatia. Ko He nui te ahua o te pūrere. e tūtohu ana ki te aromātai i te kounga o te whakaminenga hoki te tīmatanga. Me hono humarie Wae o te tahuhu. Whakamanuhiritia te kore o āputa, wahi wewete me wahi ona.

Me pēhea te ki te whiriwhiri i te multimeter mō te whakamahi kāinga? I roto i tenei take, ka uru he kirihou noa hei whakamatau. Ko ngaio, kia arotahi te whakamutunga i runga i te hoko o te pūrere, te whakakī ā-kopakia ana e te i roto i te marae hiri ātete. A, no te mahi i te multimeter i roto i ngā tono ahumahi ko reira e minaminatia e kore e te pūrere tukua te takotoranga i roto i te puehu, me te makuku.

Whakatau whakaputa e mita mō te motokā me te kāinga, e whakarongo ki nga utu, me te whakakā. Ki te hanga enei āhuatanga hanganga o te kirihou kounga rawakore, e faarahi te reira i te tūponotanga e tūnga ratou hei wewete i te tuatahi o nga marama o te mahi o te pūrere. Ka rite ki te hua, aroturuki i te inenga tika ka tino uaua. Na reira ko te reira e tika ana ki te hoatu hiahia ki multimeters ki pono, pai whakakā whakarewa.

Ki te mārama me pēhea te ki te whiriwhiri i te multimeter, e ka e whai hua i roto i te whakamahi ia rā, e hiahia ana koe ki te tahuri ki te hoatu i etahi tauira i runga i te nikau o te moni. He pai ki te hoatu hiahia ki te pūrere, e ka whakamarie ki te takoto i roto i te ringa.

Me whai ngā taura i te-wāhanga ripeka pai. He mea nui i roto i aua wā i te mea e tika ana ki te mahi inenga ki uara nui.

Ko reira minaminatia e pai whakakoi te mutunga o te uiuia. I roto i te take i taua e kore e whai tino kore raruraru ki te hiahia ki te whakaae ki nga ngā whakapā iti rawa o te ara iahiko.

I roto i te mutunga

Na ka titiro matou i pehea ki te whiriwhiri i te multimeter. I te pae hopea ko reira ia tapao ko e, ki te tika, te mahi inenga taketake pērā i te taki i tiaki pākahiko ranei tamata i te wiki, he reira pai ki te titiro i te testers iti-utu āhua. Ki te ngā mahere te whakatinanatanga o atu raruraru matatini, kia whakaaro koe te hoko i te pūrere pono multifunctional.
