Yintoni kungcono ukukhetha imitha ukuze imoto? Khangela incwadi iintlobo, amaxabiso

ukusebenza imoto lidla ezinxulumene nokwenziwa kwemisebenzi mechanical, naxa kufikwa umonakalo omkhulu. izixhobo zombane kufuna ingqalelo ekhethekileyo, ngokunjalo nokugcinwa eli candelo rhoqo uyiphathisiweyo kwiingcali. Kodwa kukho amanyathelo alula yaye ngokufuthi othintelo ukuba unako ukwenza nokuba i wemoto ongenamava. Umzekelo, kunokuba khangela indlela yesiphelo ombane okanye ukuxhathisa womlinganiselo kwi-kwibhodi womnatha ngoku. Ngokuba imisebenzi enjalo bafumana abahloli ezikhethekileyo - Multimeters. It is a isixhobo esincinane evumela ukuba imizuzu embalwa ukwenza imilinganiselo eziyimfuneko. Yintoni kungcono ukukhetha multimeter - impikiswano, kwaye impendulo inokunikwa kuphela xa iimfuno zomntu ngamnye kunye nokukhethwa umsebenzisi. Nangona kunjalo, kukho imigaqo ngokubanzi ukhetho enjalo, ulwazi leyo eya kunceda ukusombulula le ngxaki.

ulwazi ngokubanzi malunga multimeters

Le fowuni sisixhobo yokulinganisa zobukhulu ezincinane, nto leyo evumela usebenzisa uqikelelo wawo sokusebenza yaloo mmandla, kwakunye ukubonakalisa iimpawu zaso. Inguqulelo nemigangatho yokunikwa kwazo ezo zixhobo enze imisebenzi voltmeters, ammeters kunye ohmmeters. Sinako uthi yiseti zeentsebenzo, nto leyo lubonakala ngokuba imitha yendalo iphela. Yintoni kungcono ukukhetha indlu? Mhlawumbi, ngokoMthetho umxholo ezisebenzayo kule iseti yemicimbi bekuya kuba kunokunganeli kwiimfuno zasekhaya.

Nangona kunjalo, kuba isithuthi iya kuba endaweni nokunika ezongezelelweyo functionality. Ngokukodwa, ezinye iimodeli ezikhethekileyo kule hlobo nako ukusebenza nge ngqo kwi-ibhodi kwezixhobo. izixhobo ezinjalo kwenza kube lula ukufumanisa yoMgaqo isantya kunye tachometer. Nangona kunjalo, i isiqulatho ngokugqithiseleyo lwemisebenzi Akusoloko a plus ekulinganiseni umgangatho. Ngoko ke, ukuba ziyahambisana exabisa ukuya iinguqulelo umgamgatho, oveza multimeter mihla. Yintoni kungcono ukukhetha ngokwemigaqo usebenziso olulula - kuba nawo ngumba obalulekileyo, nto leyo ethatha ingqalelo bokuqonda yokusingatha isixhobo. Ngokukodwa, lula ukusetyenziswa kwefowuni iya kuxhomekeka kuhlobo lwayo.

device imihlobo

Umgaqo wokupasa candelo kunye indlela yokulawula ukunikelwa data yomlinganiselo. Imarike iyaqhubeka ukuba bafune izixhobo analog ngokuziphatha lixesha, kodwa ethembekileyo kunye nolawulo mechanical. Esi sixhobo utolo, nto leyo ayahlukanga zizityebi ukusebenza, kodwa kwangaxeshanye, ukuba ziyaqondwa luninzi, nokuba abasebenzisi abo basandula kuqalisa. Kodwa ukubuyisela abahloli odidi eza DMM. Yintoni kungcono ukukhetha ukuba imoto kule meko? Uyacetyiswa ukuba bagxininise onobuhle ngesithabatho. iinguqulelo ezinjalo, ingakumbi, ukuba ngokupheleleyo ezilungele ukusetyenziswa ngemiqulu ibhetri njengoko ukuphelisa imfuneko tooling olongezelelweyo. Ngokwawo, i multimeter yedijithali uyingenelo umfuziselo indlela mihla zokubeka data ziboniswe kwi uboniso olunombala wamanzi akhazimlayo. Inguqulelo eziphuculweyo kusetyenziswa nokuzaliswa computer, apho ukwazi ukukhupha ukusebenza data ezifunyenweyo.

Iikhrayitheriya Selection Key

Technical parameters kufuneka ibe sisiseko lokwenza ukhetho. Oku ikakhulu iphathelene uluhlu lwamaxabiso kulinganiswa. Ngokukodwa, ngokusebenzisa i multimeter kunye uluhlu olubanzi, umsebenzisi akanokukwazi kuqinisekisa amandla ezikhoyo kuluhlu ukususela 0.1 Ma ku 10 A. Kwakhona, ukusonjululwa zesiKhokelo, nto leyo inikwa imitha - yeyiphi kungcono ukukhetha kuyo ngesi salathisi? Kakade ke, kungona ubunzulu besuntswana, ngcono umgangatho nomlinganiselo. Oku kuvumela uhlolo olubanzi ixabiso elilinganiselweyo. Enye into kukuba kwisikali amancinci akufanelekanga kuzo zonke iimeko.

An bemfuno kubalulekile ukuze akhethwe nguye ukuchaneka sixhobo. Ngokusemthethweni, uchazwa impazamo ratio. Umzekelo, abahloli digital, eli xabiso sidla isusela ukusuka 0,02 ukuya-3%. Kodwa umbuzo ukuba ukhethe indlela multimeter yedijithali, ngaphandle kwanokubaluleka ngokwalo yokulinganisa mgaqo, ekubeni uphando idla siphantsi izixhobo ephantsi-amandla. Kwaye ngokubhekiselele imilinganiselo uzinzo, ngokuzenzekelayo, ngamanye amaxesha kuzibonakalisa ngcono ngokwabo ukuguqulwa kanye analog.

Model ngengozi 15B

isixhobo indawo oko kumlungele na ukusetyenziswa jikelele, kuquka imisebenzi kunye notshintsho ngamandla ekwinqwelo-jikelele. Le modeli ngummeli ezaziwa le Zinjengeqhezu abahloli digital. Oku azakubalulwa sinamazinga imposiso 0.5% kunye nobukho kweenkqubo zolawulo oluzenzekelayo. Umzekelo, ukuba kukho umbuzo malunga kungcono ukukhetha indlela imitha ukusuka kwindawo Ngenxa ubude elithi kakuhle, unako ngokukhuselekileyo Shiyiselanani kule yunithi. isilawuli esizisebenzelayo yayo ivumela ungajongwangwa ukujonga bit kakhulu efanelekileyo.
