Dab tsi yog hom multimeters?
Raws li hom, nws muab faib ua: desktop multimeter thiab tes- tuav multimeter; Raws li cov qauv, nws muab faib ua: pointer multimeter thiab digital multimeter. Raws li txoj cai ntsuas, lub ntsuas ntsuas ntsuas muaj magnetoelectric rectification hom thiab electromagnetic rectification hom. Raws li cov qauv ntawm lub 'meter', muaj sab hauv (sab nrauv) magnetic hairspring taub hau thiab nro hlau taub hau. Meter, programmable digital meter nrog (tsis muaj) interface, programmable digital meter txuas nrog PC; muab faib ua: lub hom phiaj dav dav thiab lub hom phiaj tshwj xeeb, cov khoom siv hluav taws xob dav dav xws li ntsuas qhov ntsuas hluav taws xob, tam sim no, tsis kam thiab diode triode conduction voltage poob Cov multimeters feem ntau yog siv rau cov hom phiaj tshwj xeeb, xws li grounding resistance meters, insulation resistance meters, capacitance meters, micro -ohmmeters, thiab lwm yam; Raws li lub sijhawm, lawv muab faib ua: tes- tuav ncaj- hom multimeters thiab tes- tuav clamp multimeters. Hom phaj ncaj tuaj yeem siv rau ntau lub sijhawm xws li: hluav taws xob thiab hluav taws xob, khoom siv tu, kev qhia thiab kev tshawb fawb, thiab ntau yam kev lag luam uas cuam tshuam nrog cov muaj zog thiab tsis muaj zog tam sim no. Lub clamp multimeter muaj qhov nqaim ntawm daim ntawv thov, feem ntau vim tias lub hwj chim kho yuav tsum ntsuas tsis ncaj ntawm cov dej ntws loj. Clamps yog siv. Zoo li multimeter.
