Multimeter Professional: iimpawu kunye nohlaziyo

Ubukho yemitha kule yokugcina izixhobo okanye wagon master kwezombane asinto an extra ungayikhetha, kodwa kuyimfuneko ukwenzela ukusebenza kakuhle. Le izixhobo inxulumene emininzi kuthetha ukuvumela ukuba ukuchaza iimpawu eziliqela kwisekethe yombane yokulinganisa. Ukukwazi zomlinganiselo umgangatho ophezulu kwahlukile Ukuphathwa yobungcali multimeter Noko ke, apho, kufuna ezinye uqeqesho. Ekubeni esi sixhobo, kunokwenzeka ukuba umlinganiselo kungekuphela nje amandla zangoku ombane, kodwa ukucacisa indawo ye ngokubekwa Hidden Line.

Yintoni umahluko ukusuka imifuziselo professional eqhelekileyo?

Umda phakathi zobungcali kunye nekhaya izixhobo zamtyabeka umlinganiselo abaninzi iparameters. Kwelinye icala, imifuziselo iingcali baba ngakumbi compact, ergonomic ngakumbi yaye bekhululekile xa ekubambeni physical eyenza zifane izixhobo zasekhaya. Kwelinye icala, izixhobo eqhelekileyo afakwa ukusebenza entsha, ngokunjalo ukunikezela uluhlu olubanzi imisebenzi yokulinganisa.

Noko ke, umbuzo wokuba yintoni umahluko phakathi a multimeter abaqeqeshiweyo be-iinguqulelo njengesiqhelo, ubukhulu becala zibangelwa yi-sabelo. Umzekelo, zeelebhu kunye namaziko inkonzo kaninzi baba izixhobo zokubhala, uboniso multi-bit ezahlukeneyo. Noko ke, le ingxenye kusenjalo ethile kunye elimxinwa. Iingcali iinqwelo ikakhulu ukusebenzisa iikopi eziphathekayo. Ngokungafaniyo multimeters zendlu, izixhobo ezinjalo kubonelelwa, kunye nenani iinketho ezizodwa. Ngokukodwa, isixhobo sokuqeqeshelwa ngokuzenzekelayo ukhethe ezintlwini search, uyenze, kunye nokunika ngokubanzi inkqubo womlinganiselo ngempumelelo ngakumbi.

Iimpawu eziphambili

Eyona nto ibalasele ngayo umsebenzi sele kuphawulwa uhla search. Le uluhlu womlinganiselo, apho lesixhobo kuqinisekisa salathisi kwi kwikhonkco. Ngoko ke, imifuziselo abaqeqeshiweyo zikuvumela ukuba ukubhala ngoku ubukhulu ukususela 0.1 Ma ku 10 A. Ngapha koko, kubalulekile ukuba uthathe ingqalelo isigqibo, nto leyo ichazwe kwi imitha ekubhobhozeni. Ukunenzela lula, fumanisa umsebenzisi litshintsha ixabiso ziikhowudi kuxhomekeke umsebenzi yangoku. Enoba imodeli, naziphi yobungcali multimeter kwaye luphawulwa umlinganiselo accuracy eliphezulu. Kuphonononga ukusetyenziswa kwale iyimposiso salathisi. Kwimeko kwezixhobo zombane ngayo-avareji ukusukela ku 0,025 ukuya-3%. Thelekisa, ixabiso zombane ikhaya cheap kwezinye iinguqulelo kuvumela ukuba ecaleni kwe-10%, nto leyo, Kakade, Ninganeli umninindlu, complex ukwenza kunye nokusebenza ebalulekileyo zombane.

uhlobo device

Kude kube kamva nje, omnye iimpawu ezininzi obubonakalayo ukwahlulwa multimeters abaziingcali bavakalisa lilungu Zinjengeqhezu izixhobo zedijithali.
