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.

Vim li cas thiaj muaj kev nyeem ntawv hauv ammeter thaum lub voj voog kaw?
Thaum koj qhib thiab kaw lub ammeter, cov khoom siv hlau nplaum ncig yuav tuaj tos cov inductance amplifies lawv mus rau qhov hluav taws xob uas tsav lub ntsuas. Ntau dua qhov tam sim no, qhov voltage ntau dua. Yog li koj tuaj yeem tau txais kev nyeem ncaj ncees ntawm qhov tam sim no ntws hauv lub kaw lus kaw
Dab tsi yog qhov kev nyeem ntawv ntawm infinite resistance?
Thaum koj pom qhov tsis muaj kev tawm tsam ntawm lub tshuab digital multimeter, nws txhais tau tias tsis muaj hluav taws xob tam sim no ntws los ntawm cov khoom koj ntsuas. Yog li ntawd, unlimited kuj txhais tau hais tias lub multimeter tau ntsuas ntau heev tsis kam uas tsis muaj ntws sab laug
Vim li cas qhov kev tawg ntawm daim ntawv thiab hlawv cov ntawv suav tias yog ob hom kev hloov pauv?
Tearing ntawm daim ntawv yog ib qho kev hloov ntawm lub cev vim hais tias thaum daim ntawv torn tsuas yog cov tsos ntawm daim ntawv hloov thiab tsis muaj cov khoom tshiab tsim. tearing ntawm daim ntawv yog ib qho kev hloov ntawm lub cev vim nws tseem zoo li qub tab sis qhov kub ntawm daim ntawv yog ib qho tshuaj hloov vim nws hloov mus rau hauv tshauv
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Yuav ua li cas tsis txawj nyeem ntawv yog txaus ntshai rau ib tug kev ywj pheej haiv neeg?
Kev tsis nyeem ntawv yog qhov txaus ntshai rau cov neeg ywj pheej vim tias muaj pes tsawg tus neeg muaj cai xaiv tsa uas tsis paub ntawv yog nyob deb txaus los mus pov npav. Qhov no tuaj yeem ua rau kev xaiv tsa tus thawj tswj hwm uas tsis yog kev nom kev tswv zoo li lwm tus neeg sib tw
