Qhov twg multimeter rau electricians muab tus nqi zoo tshaj?
Lub tsev multimeters tau siv tsawg dua. Tsuas yog yuav ib qho analog multimeter, uas raug nqi txog kaum tawm yuan. Nws kuj tseem haum rau cov pib tshiab, thiab nws yuav tsis ua mob rau koj yog tias nws puas lawm.

Feem ntau siv portable multimeters tuaj yeem muab faib ua peb hom, mechanical pointer multimeters, digital multimeters, thiab clamp-type digital multimeters.
Tshawb xyuas qhov zoo, qhov tsis zoo thiab tus nqi ntawm peb lub moos no.
Mechanical pointer multimeter
Hom 'meter' no tsis tshua muaj kev cuam tshuam los ntawm qhov kub thiab txias, dej ntws, thiab kev cuam tshuam ntawm magnetic teb, thiab qhov ntsuas tus nqi yog qhov ruaj khov thiab intuitive.

Tab sis koj yuav tsum kho lub iav thaum ntsuas. Thaum ib tug phooj ywg ntawm kuv ntsuas 380V voltage, nws tsis nco qab kho lub iav vim yog lub beep. Tus nqi yog pheej yig, xws li los ntawm ib lub kaum os mus txog kaum ob daus las.
Digital Multimeter
Cov khoom siv hluav taws xob Precision feem ntau cuam tshuam los ntawm ib puag ncig xws li cov hlau nplaum thiab cov av noo, tab sis yog tias nws tsis siv rau kev ntsuas hluav taws xob hauv hluav taws xob, qhov cuam tshuam yog qhov tseem ceeb lossis tsis txaus ntseeg.
