Lub ohmmeter yog ib qho khoom siv hluav taws xob uas ntsuas kev tiv thaiv hauv cov khoom siv hluav taws xob lossis hluav taws xob. Nws ua hauj lwm los ntawm kev siv 2 probes xa ib tug tam sim no los ntawm Circuit Court thiab ntsuas npaum li cas kuj, nyob rau hauv ohms ua , uas tam sim no ntsib.
Cov lus nug tseem yog, koj siv ohm nyeem ntawv li cas?
Yuav Siv Lub Ohmmeter li cas
- Tshem tawm tag nrho thiab / lossis kaw tag nrho lub zog rau lub voj voog uas koj tab tom sim.
- Txuas cov kab ntsuas mus rau ohmmeter.
- Nrog rau daim ntawv qhia kev pabcuam rau qhov kev ua haujlwm ib txwm muaj rau lub voj voog uas koj tab tom sim.
- Teem lub xov tooj mus rau "ohms (Ω)" teeb tsa nrog multimeter.
Tsis tas li ntawd, qhov kev nyeem ntawv siab ohm txhais li cas? Siab dua tus lej qhia a siab dua rating, qho txhais tau tias ntau lub zog yuav tsum tau ua kom sib xyaw ua ke hauv ib lub voj voog. Thaum koj xeem lub resistor, capacitor, lossis lwm yam khoom siv hluav taws xob, ohmmeter yuav tso saib tus lej qhia nws tsis kam.
Hais txog qhov no, nyeem ntawv ntawm 0 ohms txhais li cas?
Kuj ntsuas nyob rau hauv ohms ua nrog tsis muaj tam sim no ntws los ntawm Circuit Court. Nws qhia tias xoom ohms ua thaum tsis muaj kev tawm tsam ntawm cov ntsiab lus xeem. Qhov no qhia tau hais tias kev txuas ntxiv ntawm cov dej ntws tam sim no hauv lub kaw lus kaw. Nws qhia tias infinity thaum tsis muaj kev sib txuas hauv Circuit Court uas zoo li nyob rau hauv ib qho qhib Circuit Court.
Cov cim txhais li cas ntawm multimeter?
Yog hais tias koj yuav tsum ntsuas alternating tam sim no nyob rau hauv ib tug Circuit Court, txawv multimeters muaj qhov sib txawv cim ntsuas nws (thiab qhov sib thooj voltage), feem ntau yog "ACA" thiab "ACV," lossis "A" thiab "V" nrog ib kab squiggly (~) nyob ib sab los yog siab dua lawv.

Dab tsi yog qhov txawv ntawm daim ntawv cog lus lub zog thiab daim ntawv cog lus dissociation zog?
Qhov sib txawv tseem ceeb ntawm kev sib txuas ntawm lub zog thiab lub zog bonddissociation yog tias lub zog sib txuas yog qhov nruab nrab ntawm lub zog xav tau los rhuav tshem tag nrho cov kev sib txuas ntawm tib ob hom atoms nyob rau hauv ib qho chaw sib txuas whereas daim ntawv cog lus dissociation zog yog tus nqi ntawm cov hluav taws xob xav tau los rhuav tshem ib qho kev sib koom ua ke inhomolysis
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
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
Cov kev nyeem ntawv yog dab tsi?
Kev nyeem ntawv sojntsuam raug qhab nia raws li tus lej ntawm cov lus kom raug nyeem, thaum kev sojntsuam lej ntsuas tus lej ntawm cov lej raug. Spelling probes muab credit rau cov ntawv sau kom raug; Kev tshawb nrhiav kev sau ntawv muaj ntau qhov kev xaiv qhab nia, suav nrog tag nrho cov lus sau thiab tus lej ntawm cov lus sau raug
