Multimeter Professional: izici kanye nokubuyekeza

Ukuba khona imitha ku arsenal of amathuluzi noma inqola master ngogesi akuyona extra ozikhethela, kodwa imfuneko isebenza ngendlela efanele. Lokhu apharathasi siphathelene esisetshenziselwa yokulinganisa izindlela ngokuvumela ukuchaza izici eziningana circuit kagesi. Versatility izinga okusezingeni eliphezulu nesilinganiso kuyahluka handling professional multimeter Nokho, lapho, idinga ukuqeqeshwa abanye. Nedivaysi ezinjalo kungenzeka hhayi kuphela ukukala amandla lamanje ukuze voltage, kodwa futhi ukucacisa indawo ebeka Hidden Line.

Uyini umahluko kusuka onobuhle professional evamile?

Umngcele phakathi zikagesi professional nekhaya angabekwa yokulinganisa imingcele eminingi. Ngakolunye uhlangothi, izazi onobuhle babe emfishane, ergonomic xaxa futhi zikhululekile ngaphezulu ekuphatheni ngokomzimba okubenza efana amadivayisi yasendlini. Ngakolunye uhlangothi, amadivayisi ezivamile afakwa ukusebenza entsha, kanye ukunikela anhlobonhlobo imisebenzi yokulinganisa.

Noma kunjalo, umbuzo eveza umahluko phakathi a multimeter lobuchwepheshe nokulungiswa evamile, ngokuyinhloko kubangelwa lesi sabelo. Ngokwesibonelo, i-laboratories kanye nezikhungo zomsebenzi ngokuvamile baba kumadivayisi umile, ezahlukene multi-bit isibonisi. Nokho, le ngxenye namanje ethile futhi ayibanzi. Ochwepheshe izinqola ikakhulukazi ukusebenzisa izinguqulo ephathekayo. Ngokungafani multimeters yasendlini, amadivayisi njenge zinikezwa, futhi eziningi ongakhetha ekhethekile. Ikakhulukazi, kudivayisi professional kungaba ngokuzenzakalelayo ukhethe amabanga search, ulinganise, futhi ngokuvamile ahlinzeke ngempumelelo ngaphezulu inqubo ukulinganiswa.

Izici Key

Isici esiyinhloko salelo umsebenzi isivele kuphawulwa range search. Lokhu uhla nesilinganiso, ngaphakathi kwalo la i idivayisi lungacacisa inkomba lapha. Ngakho, onobuhle professional zikuvumela ukuba alobe samanje ezidlula kusuka 0.1 ma-10 A. Ngaphezu kwalokho, kubalulekile ukuba acabangele leli zwi lesinqumo, okuyinto sivezwe kula imitha khulula. Ukuze kube lula, thola umsebenzisi eshintsha ukubaluleka ibhithi kuncike umsebenzi wamanje. Kungakhathaliseki imodeli, iyiphi multimeter professional futhi esibonakala ngokuqina okusezingeni eliphezulu nesilinganiso ukunemba. Ukuze ukuhlola ukusetshenziswa le nkomba iphutha value. Endabeni apparatuses kagesi kuba ngokwesilinganiso kusuka 0,025 kuya ku-3%. Ukuze uqhathanise, intengo ezishibhile ekhaya Imishini kwezinye izinguqulo uvumele ukuphambuka 10%, okuyinto Yiqiniso, unganelisekile master, enza eziyinkimbinkimbi kanye nokusebenza ezibucayi kagesi.

zinhlobo kudivayisi

Kuze kube muva nje, omunye izimpawu ezibonakala kakhulu ukwehlukana multimeters professional uzwakalise lenye ingxenye amadivayisi digital. Amamodeli ne-LCD izikrini baye ngokushesha won trust abasebenzisi ngenxa yokunemba okuphezulu nesilinganiso, lula ukusetshenziswa kanye nomklamo stylish. Namuhla, phakathi amadivayisi obuchwepheshe Avame ukutholakala kanye onobuhle yasekhaya. It akabashiyi emakethe, futhi analog izinguqulo. Nakuba badlala imodeli digital ncamashi, kodwa abiza kancane. Ahlukaniswe kumadivayisi ezifana nezinye izinjongo. Namuhla akuve kuvamile multimeter professional yezimoto, esetshenziselwa ukuhlola ukusebenza inethiwekhi ugibelile. ethandwa nakakhulu enemisebenzi multimeter umhloli ifakwe imitha ngocingo. It libhekene kalula ekusingatheni ngoba aqede umsebenzisi ukwenza imisebenzi asizayo ngo ukugcinwa ingxenye ukusebenza.

Uphenyo imodeli Cem DT 916N
