Un ama-multimeters noma ama-multimeters Ingelinye lamathuluzi angeke ashoda kunoma iyiphi ilabhorethri noma indawo yokusebenzela, ngoba isetshenziselwa ukuthatha izilinganiso eziningi kanye nokuhlola ukuze kuqinisekiswe ukuthi yonke into isebenza ngendlela efanele. Ngalesi sizathu, sidale lesi sihloko ngokunye okuhle kakhulu okukhona, kanye nezinye izincomo zokuthenga ukuze ukhethe okulungile ngokwezidingo zakho. Ngakolunye uhlangothi, ngifake kokubili i-analog nedijithali, njengoba kukhona abanye abantu abasakhetha i-analog ngezizathu ezihlukahlukene.

Ungakhetha kanjani i-multimeter noma i-multimeter
Ngesikhathi sika khetha ama-multimeters noma ama-multimeter, kufanele ucabangele lokhu okulandelayo:
- I-Las imininingwane we-multimeter yedijithali ichaza ikhono ledivayisi lokukala imanje eqondile, i-alternating current, i-voltage eqondile, i-voltage eshintshanayo kanye nokumelana. Kufanele ukhethe i-multimeter yedijithali ene-voltage eyinhloko ephakeme kunaleyo edingekayo ukuze unike amandla amadivayisi kagesi ofuna ukukala ngawo. Kubalulekile ukusebenzisa i-multimeter ngaphakathi kwebanga layo lamanje ukuze ugweme ukulimala noma ukulimala kumitha. Ama-amperage aphezulu angabangela izinkinga ezinkulu.
- Kubalulekile ukwenza isiqiniseko sokuthi i-multimeter yedijithali ohlela ukuyithenga injalo kudingekile. Ukunemba kwe-multimeter kuchazwa njengomkhawulo omkhulu wephutha elamukelekayo kumanani abhekiwe.
- I-multimeter enkulu isinqumo kuthatha isikhathi eside ukuzinza ngemva kwedijithi engakwesokudla kuneyodwa yokulungiswa okuphansi ngoba ukulungiswa okuphezulu kusho amadijithi amaningi futhi ngaleyo ndlela kube nenani elikhulu lamadijithi okufanele libukwe.
- Khetha i-multimeter nge high input impedance uma ufuna ukukala izinto zikagesi ezibucayi kakhulu, ukuze uthole izilinganiso ezinembile.
- Amanye amadivaysi okulinganisa angakwazi ukukala imvamisa futhi, ngenxa yalokho, lawula amandla kagesi kanye namazinga amanje ngaphakathi kwebanga elithile lefrikhwensi. Uma into yakho esetshenziswayo inikwa amandla amandla kagesi we-AC engashintshi, qiniseka ukuthi ihlala kumafrikhwensi afanele.
- Kuhlale kuhle ukunquma i inani lamandla ekwazi ukumelana nesifunda ngaphambi kokuqala umsebenzi. Ngaphezu kwalokho, kuyadingeka ukwazi umthamo omkhulu we-overvoltage ama-polymers angakwazi ukumelana nawo ngaphandle kokulimala.
- La umsebenzi wokushisa Ukuhluka okukabili kwe-digital multimeter kukuvumela ukuthi uqaphe amazinga okushisa amabili ngesikhathi esisodwa uma udinga ukuqapha izinga lokushisa njalo.
- Ezinye ze-multimeters amabhrendi athengiswa kakhulu futhi aziswa kakhulu I-Fluke, i-Meco, i-PeakTech, i-Mastech, i-Rishabh, i-HTC, i-Extech, i-Motwane ne-Sigma. Laba bakhiqizi banikeza ama-multimeters edijithali anembile futhi athembekile.
Ngokucabangela lokhu kucatshangelwa, uzokwazi ukukhetha i-multimeter enkulu ngokwezidingo zakho noma umane uzikhawulele ekukhetheni esinye sezincomo engizenzile ohlwini lwangaphambilini, lwedijithali ne-analog, nakuba mina mathupha ngincoma edijithali ukuze kube lula. .
