Multimeter capacitance cim thiab nyeem nws li cas

Kev ntsuas qhov ntsuas qhov tseeb yuav tsum tau siv cov cuab yeej kim, tab sis digital lossis analog multimeter tuaj yeem muab tswv yim rau koj. Cov ncej no tham txog lub cim multimeter capacitance thiab nyeem nws li cas.

Multimeter capacitance cim «–| (-."

Ua raws li cov kauj ruam hauv qab no kom nyeem cov cim multimeter capacitance.

Ua ntej tig koj lub analog lossis digital multimeter. Ntxig cov ntsaws rau hauv cov chaw nres nkoj kom raug ntawm lub multimeter. Tom qab ntawd tig lub pob qhov rooj multimeter kom txog thaum nws taw qhia rau lub cim multimeter capacitance. Tom qab ntawd xyuas seb koj DMM puas muaj REL khawm. Koj yuav tsum tau nyem rau ntawm nws nrog cov kev xeem sib cais. Tom ntej no, disconnect tus capacitor los ntawm Circuit Court. Tom qab ntawd txuas qhov kev xeem coj mus rau lub capacitor terminals. Tawm mus rau qhov kev xeem coj mus rau ob peb feeb rau lub multimeter txiav txim siab qhov tseeb.  

Qhov peev xwm yog dab tsi?

Tus nqi hluav taws xob uas khaws cia hauv ib yam khoom yog hu ua peev. Ib qho piv txwv zoo yog capacitors hauv hluav taws xob circuits.

Multimeter capacitance cim 

Ib qho ntawm feem ntau siv cov cim multimeter yog lub cim multimeter capacitance. Koj tsis tuaj yeem ntsuas capacitance tshwj tsis yog koj paub tias koj tab tom nrhiav dab tsi ntawm DMM. Yog li ntawd, lub cim no yog dab tsi?

Multimeter capacitance cim “–| (–.”

Yuav ua li cas ntsuas capacitance nrog multimeter

1. Teeb tsa koj lub cuab yeej 

Qhib koj lub analog lossis digital multimeter. Ntxig cov ntsaws rau hauv cov chaw nres nkoj kom raug ntawm lub multimeter. Cov hlau liab txuas mus rau qhov chaw nres nkoj cim nrog lub cim capacitance ntawm multimeter (–|(–). Txuas cov hlau dub rau qhov chaw nres nkoj cim “COM”. (1)

2. Teeb tsa DMM los ntsuas qhov muaj peev xwm. 

Tig lub qhov rooj multimeter kom txog rau thaum nws taw qhia rau lub cim multimeter capacitance. Tag nrho cov multimeters siv lub cim no - (–|(–). Yog tias koj siv ib lub multimeter sib txawv, koj tuaj yeem siv lub khawm daj ua haujlwm los teeb tsa DMM los ntsuas qhov peev xwm. , nco ntsoov nias lub khawm daj kom txog thaum lub cim multimeter capacitance tshwm.

3. Qhib REL hom

Xyuas seb koj DMM puas muaj REL khawm. Koj yuav tsum tau nyem rau ntawm nws nrog cov kev xeem sib cais. Qhov no nulls lub capacitance ntawm qhov kev xeem coj, uas yuav cuam tshuam nrog lub multimeter capacitance ntsuas.

Nws yog qhov tsim nyog? Tsuas yog thaum ntsuas me me capacitor.

4. Disconnect lub capacitor ntawm lub Circuit Court.

Koj tsis tuaj yeem ntsuas farads thaum lub capacitor tseem txuas nrog lub voj voog. Ceev faj thaum tuav cov capacitors vim kev tuav tsis raug tuaj yeem ua rau hluav taws xob poob siab. Thaum disconnect tus capacitor los ntawm ib qho hluav taws xob hluav taws xob, hnav cov khaub ncaws tiv thaiv thiab cov khoom siv xws li looj tsom iav dub thiab cov hnab looj tes insulating.

5. Ntsuas qhov capacitance 

Tom qab ntawd txuas qhov kev xeem coj mus rau lub capacitor terminals. Tawm mus rau qhov kev xeem coj mus rau ob peb feeb rau lub multimeter txiav txim siab qhov tseeb. (2)

Tam sim no koj tuaj yeem nyeem qhov capacitance multimeter nyeem ntawm qhov screen. Yog tias tus nqi capacitance tshaj qhov ntsuas qhov ntsuas, cov zaub yuav qhia OL. Tib yam yuav tsum tshwm sim yog tias koj lub capacitor faulty.

Summing txog

Tam sim no koj paub yuav ua li cas ntsuas capacitance nrog multimeter. Peb vam tias koj pom cov lus qhia no yuav pab tau thaum koj siv DMM los ntsuas qhov muaj peev xwm. Xav tias dawb nyeem peb lwm cov lus qhia yog tias koj tau daig. Peb tau teev ob peb hauv qab no.
