I-Multimeter vs Voltmeter: Uyini umehluko?

Uma uthanda ukusebenza nge-electronics, kufanele wazi ukuthi kokubili ama-multimeters nama-voltmeters angamathuluzi awusizo kakhulu futhi abalulekile ngezindlela eziningi. Nokho, kungase kube nokudideka kwabanye abantu ngokuthi iyiphi evumelana kangcono nezidingo zabo. Yize sinesiqiniseko sokuthi cishe unombono ojwayelekile wokuthi ngalinye lalawa mathuluzi elenzani, ukubhekisisa kungasiza kakhulu lapho usebenza kuphrojekthi.

Ukukusiza ukuthi uqonde kangcono womabili la mathuluzi kanye nomehluko phakathi kwawo, funda lo mhlahlandlela okulula ukuwuqonda. Sizohlola izici zedivayisi ngayinye nokuthi zihluke kanjani kwenye ngokuya ngokusebenza.

I-voltmeter iyithuluzi elisebenza ngezindlela eziningi elikala i-voltage kuphela. I-multimeter, ngakolunye uhlangothi, inikeza izinketho eziningi kakhulu, kodwa futhi ibiza kakhulu ngesizathu esifanayo. Lokhu kuphinde kubangele umehluko omkhulu kumanani abo njengoba ama-multimeters ebiza kakhulu.

I-Multimeter vs voltmeter: iyiphi ongayikhetha?

Lesi yisinqumo okufanele usenze sincike ngokuphelele ekutheni idivayisi ngayinye isebenza kanjani. Empeleni, kuhlobene nohlobo lwesilinganiso oyifunayo nokuthi yimalini ongayisebenzisa. Ngokuqonda izidingo zakho, kufanele ukwazi ukunquma ukuthi iyiphi kulezi ezimbili ezokusebenzela kangcono.

Funda ngokucophelela ulwazi olulandelayo mayelana nedivayisi ngayinye ukuze uthole ukuthi ngayinye yenzani nokuthi ingasithinta kanjani isinqumo sakho.

Ukuqonda Umsebenzi We-Voltmeter

Umsebenzi oyinhloko we-voltmeter ukukala i-voltage edlula phakathi kwamanodi amabili. Ngokombono wezobuchwepheshe, i-volt iyiyunithi yomehluko ongaba khona phakathi kwamanodi amabili, futhi lo mehluko ulinganiswa ngama-volts. I-voltage ngokwayo iza ngezinhlobo ezimbili njengoba sinezinhlobo ezimbili zama-currents okungukuthi i-direct current (DC) ne-alternating current (AC). Amanye ama-voltmeter akala amandla amanje aqondile kuphela, kanti amanye akala amandla ashintshayo kuphela. Bese uba nenketho yama-voltmeters akala womabili kudivayisi efanayo.

Ukwakhiwa kwangaphakathi kwesihloli se-voltage kulula futhi kuqukethe kuphela ikhoyili yocingo oluncane oluphethe intambo yamanje elenga endaweni yangaphandle kazibuthe. Idivayisi iza nama-clamp amabili okuthi, uma exhunywe kumanodi amabili, ahambise okwamanje ngocingo olungaphakathi. Lokhu kubangela ukuthi ucingo lusabele endaweni yamagnetic, futhi ikhoyili lapho itholakala khona iqala ukujikeleza. Lokhu kuhambisa isikhombisi sokulinganisa esibukweni, esibonisa inani le-voltage. Ama-voltmeter edijithali aphephe kakhulu kunamamitha enaliti futhi atholakala kabanzi kulezi zinsuku. (1)

I-Eversame Flat US Plug AC 80-300V LCD Digital Voltmeter

Ngenkathi isihloli sikagesi esichazwe ngenhla sikala amaphuzu ahlukahlukene, ungathola futhi amadivayisi akhiphekayo njenge-Eversame Flat US Plug AC 80-300V LCD Digital Voltmeter, ebonisa amandla kagesi ageleza endaweni ethile yodonga. Isetshenziselwa ukuqapha amadivaysi axhunywe ezindaweni zokuphuma futhi ingasiza ekuvimbeleni umonakalo ongaba khona kagesi uma kwenzeka ukuqhuma kwamandla.

Yenzani i-multimeter?

Into eyodwa i-multimeter engayenza ukwenza njenge-voltmeter. Ngakho-ke, uma uthenga ngisho ne-analog multimeter, uzokwanelisa ngokuzenzakalelayo isidingo sakho se-voltmeter. I-multimeter ingakwazi ukukala i-voltage kanye namayunithi kagesi njengamanje kanye nokumelana. Ama-multimeters athuthuke kakhulu futhi akala amapharamitha afana namandla, izinga lokushisa, imvamisa, i-inductance, i-asidi, nomswakama ohlobene.

Ama-internals e-multimeter ayinkimbinkimbi kakhulu futhi afaka ezinye izingxenye ezinjengama-resistors, ama-capacitor, izinzwa zokushisa, nokuningi. Ngokombono wezobuchwepheshe, kulula kakhulu ukubona ukuthi i-multimeter iyithuluzi elisebenza kakhulu kune-voltmeter elula.

UYIGAO TRMS 6000 multimeter yedijithali

Isibonelo se-voltmeter yokusebenza okuphezulu i-UYIGAO TRMS 6000 multimeter yedijithali, idivayisi enikeza izinketho ezimbalwa zokulinganisa ongakhetha kuzo. Ngale divayisi, ungakwazi ukukala amayunithi amaningi okulinganisa, okuhlanganisa izinga lokushisa, amandla, i-voltage ye-AC, i-AC current, i-DC voltage, i-DC yamanje, imvamisa, nokumelana.

Idivayisi iphinde inikeze ezinye izici ezikhethekile ezifana nebhiphu, i-auto and manual range, ukuthola i-NCV, nokucisha okuzenzakalelayo ukuze kongiwe amandla ebhethri. Idivayisi iphinde ibe nesibonisi esikhulu esingu-3-intshi okulula ukusifunda nokukhanyisa ngemuva. Ifanele ukusetshenziswa kochwepheshe futhi inezindlu ezihlala isikhathi eside ukuze igweme ukulimala okungenzeka lapho iwiswa. Ungakwazi futhi ukuyibeka endaweni eyisicaba usebenzisa isiteji esifakiwe. (2)

Ukufingqa

Njengamanje, cishe usuyaqonda ukuthi lawa madivaysi amabili ahluke kakhulu komunye nomunye ngokuya ngokusebenza kwawo. I-voltmeter ilula kakhulu kodwa ingaba nezinhlobonhlobo zomumo nosayizi ukuze isetshenziswe engaguquki futhi elula. Kubuye kube inketho eshibhile kokubili, kodwa lokhu futhi kungenxa yokusebenza kwayo okulinganiselwe. Ama-multimeters, ngakolunye uhlangothi, angamathuluzi aguquguqukayo angakusiza ezinhlobonhlobo zezinhlelo zokusebenza, kodwa kuzodingeka ukhiphe imali eningi uma ufuna. Cabanga ngezidingo zakho futhi ungakwazi kalula ukunquma ukuthi yini ezokufanela kangcono.
