Kev ntsuas ntawm Zero, lossis ze ze rau xoom (tsawg dua.5 OHM ) qhia ib tug heev tsis muaj zog rau tam sim no. Siv voltage rau qhov no qis qib ntawm tiv taus ua rau muaj kev kub siab tam sim no.

Cia li xav txog qhov no, nws txhais li cas kom muaj kev tawm tsam tsawg?

p > Yog tias qhov screen qhia tsis muaj zog , nws txhais tau tias tus tsis kam yog ib yam qis kom txhawb tau. Feem ntau, ntau qhov laj thawj tuaj yeem ua rau muaj teeb meem zoo li no.<

Ib yam li ntawd, 0 txhais li cas ntawm multimeter? Qhov screen qhia tus nqi ntawm xoom (los yog zero), thiabthe multimeter beeps. Kev txuas ntxiv! Yog tias qhov ntsuas tam sim no tsis kuaj pom, nws txhais tau tias tsis muaj kev txuas ntxiv. Lub vijtsam yuav tso tawm 1 lossis OL (qhib voj).

Ib yam li ntawd, nws raug nug, qhov kev nyeem ntawv siab txhais li cas?

Nyeem tus tsis kam tus nqi. Siab dua tus lej qhia a siab dua rating, qho txhais tau tias ntau zog yuav yuav tsum tau integrate lub Cheebtsam nyob rau hauv ib tug Circuit Court. Thaum koj xeem ib resistor , capacitor, lossis lwm yam khoom siv hluav taws xob, lub ohmmeter yuav tso saib tus lej qhia nws tsis kam.

Muaj pes tsawg ohms suav hais tias yog luv?

Lub siab tiv thaiv txhais tau hais tias qhib Circuit Court. Lowresistance - txog 2 ohms ua los yog tsawg - qhia tias a luv Circuit Court.
