Imitha engcono kakhulu yokuqinisa | Qeda ku-Era of Probes

Ukulungisa imitha yakho kusekhethi kungaba buhlungu obukhulu ku-bum, yingakho amamitha okubamba. Lezi yikhulu lama-21 ukuthatha ama-multimeter. Ngisho nama-multimeters e-analog abe ngokoqobo muva nje, yebo bekuyikhulu leminyaka edlule kodwa namanje, kusanda kwenzeka uma kukhulunywa ngezinto ezintsha nokusungulwa.

Ukuthola imitha yokuqinisa i-top-notch kuzoxazulula leyo nkinga futhi kukusize ulinganise ngaphezu kwama-amps nje. Kodwa umbuzo uwukuthi ungayithola kanjani imitha yokubopha engcono kakhulu emhlabeni ogcwele izinkampani ezithi umkhiqizo wazo ungcono kakhulu. Hhayi-ke, sishiyele leyo ngxenye, njengoba silapha ukuze sinikeze umzila ocacile obheke ekutholeni idivayisi oyidingayo.

Umhlahlandlela wokuthenga we-Clamp Meter

Nansi inqwaba yezinto okufanele uzikhumbule ngenkathi ucinga imitha yokubopha yenotshi ephezulu. Le ngxenye iqukethe lokho okufanele ukulindele nalokho okufanele ukugweme, ngendlela enemininingwane. Uma usudlule ohlwini olulandelayo, ngibheja ukuthi ngeke ubuze muntu ngaphandle kwakho ukuze uthole iseluleko.

Umzimba Wemitha Nokuqina

Qiniseka ukuthi imitha inomzimba omangelengele owakhiwe kahle futhi okwazi ukumelana nokuwa okuningi okuvela esandleni sakho. Akufanele uthenge umkhiqizo onekhwalithi yokwakhiwa engeyinhle, njengoba ngeke wazi ukuthi idivayisi izoshelela nini ezandleni zakho.

Isilinganiso se-IP futhi siyisici esibalulekile sokuqina, futhi ungasihlola ukuze uthole isiqiniseko esengeziwe. Uma i-IP iphakeme, imitha iba namandla okuqina angaphandle. Amanye amamitha afika nekhava yenjoloba futhi anomkhawulo wokuqina okuthe xaxa kunalawo angenazo izinto zokumboza.

Uhlobo lweskrini

Cishe bonke abakhiqizi bathi bahlinzeka ngesikrini esinokulungiswa okuphezulu. Nokho, eziningi zazo zibonakala zingezinhle. Ngakho-ke, kungcono ubheke imitha enesikrini se-LCD, esikhulu ngokwanele. Futhi, hamba ngeyodwa enezibani zangemuva njengoba ungase udinge ukukala ebumnyameni.

Ukunemba nokunemba

Ukunemba ngokungangabazeki kuyinto ebaluleke kakhulu ngoba phela, isilinganiso samapharamitha kagesi, kanjalo nokunemba. Qaphela imikhiqizo enohlu olude kakhulu lwezici kodwa engasebenzi kahle ngokuya ngokunemba. Kungcono ubheke labo abanazo zonke izici oyozidinga futhi unikeze ukufundwa okunembile ngaso sonke isikhathi. Ungamthola kanjani onjalo? Vele uhlole ukuthi yini uma ileveli yokunemba iseduze namaphesenti angu-+/-2.

Imisebenzi

Nakuba sikholelwa ukuthi unolwazi olungcono ngezinjongo zemitha yakho yokubopha, ake siphinde sivakashele yonke imikhakha. Ngokuvamile, imitha enenani kufanele isebenze ekukaleni amandla kagesi e-AC/DC kanye namanje, ukumelana, amandla, ama-diode, izinga lokushisa, ukuqhubeka, imvamisa, njll. Kodwa khumbula izidingo zakho futhi ungajahi ukuthenga noma yini eza nazo zonke lezi.

Ukutholwa kwe-NCV

I-NCV imele igama elithi voltage non-contact. Kuyisici esihle kakhulu esikuvumela ukuthi ubone i-voltage ngaphandle kokuxhumana nesekethe futhi uhlale uphephile ekushayweni kukagesi nezinye izingozi. Ngakho-ke, zama ukubheka amamitha okubamba afaka i-NCV. Kodwa akufanele ulindele i-NCV enembile kulabo abanikeza yona ngentengo ephansi.

I-RMS yangempela

Ukuba nemitha yocingo ene-RMS yangempela kuzokusiza ukuthi uthole ukufundwa okunembile ngisho noma kukhona amagagasi ahlanekezelwe. Uma uthola lesi sici sikhona kudivayisi futhi singena kahle kubhajethi yakho, kufanele usithathe. Uma ukulinganisa kwakho kubandakanya inani lezinhlobo ezahlukahlukene zamasiginali, kusho ukuthi kufanele ube nesici sakho.

I-Auto Range System

Izinsimbi zikagesi nezisetshenziswa zokulinganisa zijwayele ukuba nezingozi ezimbalwa ezihlanganisa ukushaqeka nomlilo lapho i-oda lamandla kagesi kanye nezilinganiso zamanje zingafaniswa. Isixazululo sesimanje sokususa ukukhethwa kobubanzi okwenziwa ngesandla wumshini ozishintshayo.

Okwenziwa yilokhu ukuthi ikusiza ngokuthola ububanzi bezilinganiso kanye nokulinganisa kulobo bubanzi ngaphandle kokulimaza idivayisi. Ngakho-ke, umsebenzi wakho ukhululeka kakhulu njengoba ungasadingeki ulungise izindawo zokushintshela ngenkathi ubeka isigxivizo sokuthatha ukufundwa. Futhi ngokuqinisekile, imitha ithola ukuvikeleka okukhulu.

Ukuphila Battery

Iningi lamamitha okubamba laphaya lidinga amabhethri ohlobo lwe-AAA ukuze asebenze. Futhi amadivaysi ekhwalithi ephezulu afika nezici ezifana nenkomba yebhethri ephansi, okudingeka uyithole. Ngaphandle kwalokhu, uma ufuna ukuphila kwebhethri okunwetshiwe, kufanele ukhethe lawo acisha ngokuzenzakalelayo ngemva kokungasebenzi isikhathi esithile.

Isilinganiso samamitha

Kuwukuhlakanipha ukubheka imikhawulo ephakeme yezilinganiso zamanje. Ake sithi, unamathisela imitha ngesilinganiso samanje sama-ampere angu-500 kulayini wama-ampere angu-600 ngaphandle kokwazi. Izenzo ezinjalo zingase ziholele ezinkingeni ezingathi sína zokuphepha. Ngaso sonke isikhathi cabanga ukuthenga ama-clamp metres anezilinganiso eziphezulu zamanje kanye ne-voltage.

Izinga Lokuphepha

Izici ezengeziwe

Ukulinganisa izinga lokushisa nge-clamp meter yakho kuzwakala kupholile kodwa kungase kungadingeki. Kunemikhiqizo eminingi laphaya eza nezinto eziningi ezikhangayo njengamathoshi, Intambo yoku kala, izinzwa ze-alamu ezizwakalayo nakho konke lokho. Kodwa kufanele uqhubeke nokuthenga leyo ebeka kuqala ukunemba ngaphezu kwenani lezici.

Usayizi Womhlathi kanye Nomklamo

Lawa mamitha afika namasayizi emihlathi ahlukene mayelana nokusetshenziswa okuhlukahlukene. Zama ukuyithenga enomhlathi ovuleke kakhulu uma ufuna ukukala izintambo eziwugqinsi. Kungcono kakhulu ukuthola umshini oklanywe kahle okulula ukuwubamba futhi ongasindi kakhulu ukuwuthwala.

I-Clamp Meters ehamba phambili ibuyekeziwe

Ukwenza uhambo lwakho oluya kumitha ye-clamp yezinga eliphezulu lube bushelelezi, ithimba lethu liye lajula futhi lenza uhlu lwemikhiqizo ebaluleke kakhulu ngaphandle. Uhlu lwethu olulandelayo luqukethe amadivayisi ayisikhombisa kanye nalo lonke ulwazi odinga ukulwazi mayelana nawo ukuze uthole ekufanelekela kangcono.
