Thaum koj pom cov infinite kuj ntawm lub multimeter digital, nws txhais tau hais tias tsis muaj hluav taws xob tam sim no ntws los ntawm cov khoom koj ntsuas. Yog li ntawd, unlimited tsis kam txhais tau hais tias lub multimeter tau ntsuas ntau heev tsis kam tias tsis muaj ntws tawm.

Ib yam li ntawd, kev nyeem ntawv tsis kawg ohm yog dab tsi?

Infinity ohms - Qhov no yog qhov ohmmeter nyeem thaum muab tso rau ntawm qhov qhib Circuit Court. Nyob rau hauv ib qho analog meter infinity ua ohms yog thaum rab koob tsis txav txhua qhov thiab ntawm lub ntsuas ntsuas digital infinity ua ohms yog 1.

Tsis tas li ntawd, dab tsi suav tias yog kev tiv thaiv siab? Siab hluav taws xob tsis kam yog qhov kev tawm tsam rau tam sim no ntws hauv ib lub voj voog. A siab hluav taws xob tsis kam ntawm tus neeg xyuas pib hluav taws xob yog qhov cuam tshuam rau qhov ntws ntawm cov hluav taws xob tam sim no los ntawm tus neeg xyuas pib; inverse ntsuas yog hu ua hluav taws xob conductance. SI unit of electronics tsis kam yog ohm (O).

Yog li ntawd, dab tsi yog qhov kev nyeem ntawv zoo?

Cov tsis kam ntawm ib qho kev tivthaiv tuaj yeem nyob ntawm ohms (1 ohm) mus rau megaohms (1, 000, 000 ohms). Yuav kom tau txais qhov tseeb nyeem ntawv ntawm tsis kam Koj yuav tsum teem lub multimeter rau qhov zoo rau koj cov khoom. Yog tias koj tsis paub qhov ntau, pib nrog qhov nruab nrab qhov chaw, feem ntau 20 kilo-ohms (kΩ).

Puas yog Ol txhais tau tias tsis muaj kev tawm tsam?

Infinite kuj (qhib Circuit Court) yog nyeem raws li OL ” ntawm Fluke meter zaub, thiab txhais tau tias tus tsis kam yog ntau tshaj qhov ntsuas tau.
