A tsis tiv tauj voltage tester yog txoj kev ceev tshaj plaws thiab yooj yim tshaj plaws los xyuas kom muaj kev nyab xeeb ntawm cov hluav taws xob tam sim no hauv cov hlau, qhov hluav taws xob, hloov, lossis lub teeb qub uas tau ua haujlwm tsis zoo. Nws yog ib qho cuab yeej muaj txiaj ntsig uas txhua tus kws kho hluav taws xob nqa.

Ntawm no, NCV yog dab tsi ntawm multimeter?

Yooj yim-rau-siv lub hnab tshos ntse multimeter nrog AutoSensing feature ua rau lub ntsuas ntsuas kom paub txog cov tswv yim thiab hloov mus rau hom kev ua haujlwm raug (piv txwv li Voltage to Resistance ntsuas). Built-in Tsis Sib cuag Voltage ( NCV ) Ntes tso cai rau kev tshawb nrhiav ceev ntawm qhov hluav taws xob nyob.

Tsis tas li ntawd, thaum twg koj yuav tsum siv tus tsis kov tester? A tsis sib cuag hluav taws xob kuaj yog txoj kev nyab xeeb tshaj plaws rau xyuas kom lub hwj chim tawm tsis kov tej kab. Qhov no yog qhov twg tsis sib cuag hluav taws xob kuaj los nyob rau hauv ke. Cov tester yuav teeb thiab / lossis ua suab nrov thaum nws los ze rau kub (nyob) hlau, txawm ib uas yog them nyob rau hauv yas rwb thaiv tsev.

Hauv qhov no, NCV suav nrog li cas?

NCV ua tau txiav txim paj hlwb puas thiab puas. Thaum lub sij hawm kuaj, cov hlab ntsha yog stimulated, feem ntau nrog cov electrode thaj ua rau thaj uas txuas rau ntawm daim tawv nqaij. Ob lub electrodes tau muab tso rau ntawm daim tawv nqaij hla cov hlab ntsha. Ib qho electrode txhawb cov paj hlwb nrog cov hluav taws xob me me thiab lwm cov electrode sau nws.

Puas yog lub ntsuas hluav taws xob zoo ib yam li multimeter?

Qhov sib txawv ntawm ob lub cuab yeej no ncaj nraim. Yog tias koj tsuas xav tau ntsuas hluav taws xob , ces koj nyob zoo nrog ib voltmeter ntsuas . Yog koj xav ntsuas hluav taws xob thiab lwm yam xws li kev tiv thaiv thiab tam sim no, ces koj yuav xav tau ib multimeter.
