Direct Current Voltage (DCV): Qee zaum nws yuav muab txhais nrog V- hloov. Qhov kev teeb tsa no yog siv rau ntsuas direct tam sim no (DC) voltage nyob rau hauv tej yam xws li roj teeb. Direct Tam sim no Amperage ( DCA ): Zoo ib yam li DCV, tab sis tsis yog muab koj qhov kev nyeem ntawv voltage, nws yuav qhia koj lub amperage.

Hais txog qhov no, DCA multimeter yog dab tsi?

txawv multimeters muaj cov cim sib txawv uas ntsuas tam sim no ncaj qha (thiab qhov sib thooj voltage), feem ntau " DCA " thiab "DCV," los yog "A" thiab "V" nrog ib tug ncaj bar saum ornext rau lawv. Hloov tam sim no (abbreviated AC) yog tam sim no uas hloov cov kev taw qhia, feem ntau ntau zaus hauv ib ob.

Ib yam li ntawd, ACV ntsuas li cas ntawm ib qho multimeter? OHM: Cov kev teeb tsa no tso cai rau cov multimeter siv los ua ohmmeter rau ntsuas qhov tsis kam ntawm cov khoom siv hluav taws xob. ACV : Lwm voltmeter ntsuas kev teeb tsa, lub sijhawm no ntsuas alternating tam sim no voltages. Lub qhov hluav taws xob ntawm phab ntsa hluav taws xob yog qhov hluav taws xob AC.

Tsis tas li ntawd, koj nyeem DCA multimeter li cas?

Tig rau koj multimeter . Teem lub dial rau pem hauv ntej ntawm lub 'meter' mus ntsuas direct tam sim no amperes; nws ib txwm muaj cov ntawv DCA los yog ADC. Ntxig lub ntsaws rau ntawm qhov kawg ntawm qhov dub multimeter xaim rau hauv lub qhov "COM". Ntxig lub ntsaws rau ntawm qhov kawg ntawm qhov liab multimeter xaim rau hauv lub milliamp, lossis "mA," lub qhov (socket).

Koj ntsuas AC voltage li cas?

. Qee qhov digital multimeters (DMMs) kuj suav nrog m?.

  • Ua ntej ntxig cov hlau lead dub rau hauv COM jack.
  • Tom ntej no ntxig cov hlau lead liab rau hauv VΩ jack.
  • Txuas qhov kev xeem coj mus rau hauv Circuit Court: dub lead ua ntej, redsecond.
  • Nyeem qhov ntsuas hauv cov zaub.
