Un multimeters okanye multimeters Sesinye sezixhobo ezingenakusilela kuyo nayiphi na ilabhoratri yomenzi okanye iworkshop, kuba isetyenziselwa ukuthatha imilinganiselo emininzi kunye novavanyo lokuqinisekisa ukuba yonke into isebenza ngokuchanekileyo. Ngesi sizathu, senze eli nqaku kunye nezinye zezona zilungileyo ezikhoyo, kunye nezinye iingcebiso zokuthenga ukukhetha okulungileyo ngokweemfuno zakho. Kwelinye icala, ndibandakanyile zombini i-analog kunye nedijithali, kuba kukho abantu abasakhetha i-analog ngezizathu ezahlukeneyo.

Indlela yokukhetha i-multimeter okanye i-multimeter
Ngexesha le khetha i-multimeters okanye i-multimeters, kufuneka uthathele ingqalelo le miba ilandelayo:
- Las iinkcukacha ye-multimeter yedijithali ichaza ukukwazi kwesixhobo ukulinganisa i-current ngqo, i-alternating current, i-voltage ngqo, i-voltage eguqukayo kunye nokumelana. Kuya kufuneka ukhethe i-digital multimeter enevoltheji yokuqala ephezulu kuneyafunekayo ukunika amandla izixhobo zombane ofuna ukuthatha imilinganiselo kuzo. Kubalulekile ukusebenzisa i-multimeter ngaphakathi koluhlu lwangoku ukuze ugweme ukulimala okanye umonakalo kwimitha. Umgangatho ophezulu unokubangela iingxaki ezinzulu.
- Kubalulekile ukuqinisekisa ukuba i-digital multimeter oceba ukuyithenga iyimfuneko. Ukuchaneka kwe-multimeter kuchazwa njengomda ophezulu wempazamo eyamkelekileyo kumaxabiso aqatshelweyo.
- I-multimeter enkulu sigqibo Kuthatha ixesha elide ukuhlalisa emva kwenani elisekunene kunesinye sesisombululo esisezantsi kuba isisombululo esiphezulu sithetha amadijithi amaninzi kwaye ngoko uluhlu olukhulu lwamanani okujongwa.
- Khetha i-multimeter nge i-impedance ephezulu ukuba ufuna ukulinganisa ezona zixhobo zombane zibuthathaka, ukufumana imilinganiselo echanekileyo.
- Ezinye izixhobo zokulinganisa zinako ukulinganisa amaza kwaye, ngenxa yoko, lawula amandla ombane kunye namanqanaba angoku ngaphakathi koluhlu oluthile lwamaza. Ukuba isixhobo sakho sisebenzisa amandla ombane e-AC angaguqukiyo, qiniseka ukuba sihlala kumaza omoya achanekileyo.
- Kuhlala kucetyiswa ukumisela i umthamo wamandla ekwaziyo ukumelana nesiphaluka ngaphambi kokuqalisa umsebenzi. Ukongezelela, kuyimfuneko ukwazi ubuninzi be-voltage overvoltage ezinokuthi iipolymers zikwazi ukumelana nazo ngaphandle kokulimala.
- La umsebenzi wobushushu Umahluko ombindi wedijithali wemultimeter ikuvumela ukuba ujonge amaqondo obushushu amabini ngaxeshanye ukuba ufuna ukujonga ubushushu rhoqo.
- Ezinye ze-multimeters iibrendi ezithengiswa kakhulu nezixatyiswa kakhulu Zizi Fluke, Meco, PeakTech, Mastech, Rishabh, HTC, Extech, Motwane kunye neSigma. Aba bavelisi banikezela ngee-multimeters zedijithali ezichanekileyo nezithembekileyo.
Ukuthathela ingqalelo ezi ngqwalasela, uya kuba nakho ukukhetha i-multimeter enkulu ngokweemfuno zakho okanye ngokulula uzilinganisele ekukhetheni enye yeengcebiso endizenzileyo kuluhlu oludlulileyo, zombini idijithali kunye ne-analog, nangona ndicebisa ngokwam lula.
