Cov ntsuas hluav taws xob feem ntau siv hauv kev lag luam muaj peev xwm nyeem tau ntau tshaj ib hluav taws xob yam ntxwv. Cov feem ntau siv hluav taws xob ntsuas yog lub volt-ohm-milliammeter thiab lub clamp-on ammeter nrog lub peev xwm nyeem volts thiab ohms.

Hais txog qhov no, dab tsi yuav tsum tau xav txog thaum yuav ib lub ntsuas hluav taws xob?

tus nqi, raug, durability, yam ntxwv, thiab warranty.

Tsis tas li ntawd, lub tswv yim dab tsi yog siv nyob rau hauv lub ntsuas hluav taws xob los xam lub voj voog? Kev siv cov ntsuas digital Ohm lawd ntsuas thiab tso saib cov Circuit Court yam ntxwv. Qhov no tuaj yeem ua tau yooj yim vim tias tsuas muaj peb qhov sib txawv hauv Ohm txoj cai: Qhov twg yog qhov voltage, tam sim no, thiab tsis kam.

Tom qab ntawd, hom hluav taws xob sib txawv yog dab tsi?

Muaj plaub lub ntsiab hom hluav taws xob ntsuas : Flat-rate, ncua sij hawm, hnub ci thiab ntse meters . Hnub ci meters tseem muaj peb sub- hom : Net meters , ob-directional meters thiab dual metering. Cov meter koj muaj peev xwm cuam tshuam koj hluav taws xob tus nqi.

Dab tsi yog qhov tseeb ntawm feem ntau analogue?

Cov qhov tseeb tshaj plaws nyeem ntawv rau ib analog ' meter ' yog ib txoj hauj lwm pointer ntawm 2/3 ntawm tag nrho cov nplai thiab tag nrho cov nplai. Feem ntau, dc voltage ntsuas siv tag nrho suav muaj peev xwm ntawm ADC, txij li cov teeb liab txias yog ncaj nraim rau pem hauv ntej: nws siv cov kev faib tawm thiab cov ntxaij lim dej.
