Multimeter Circuit Court cim thiab lawv lub ntsiab lus

19.02.2023 /

Multimeter yog siv los ntsuas qhov voltage, tsis kam, tam sim no thiab txuas ntxiv. Nws yog ib qho ntawm cov cuab yeej siv hluav taws xob ntau tshaj plaws. Qhov tom ntej uas yuav tsum tau ua tom qab kev yuav khoom yog kawm yuav ua li cas nyeem ntawv kom raug.

Koj puas muaj digital multimeter tab sis tsis paub yuav pib qhov twg? Koj tuaj txog ntawm qhov chaw. Thov nyeem ntawv kom paub txhua yam koj xav paub txog multimeter Circuit Court cim thiab lawv lub ntsiab lus.

Multimeter cim koj yuav tsum paub 

Cov cim multimeter yog cov uas koj yuav pom ntawm daim duab kos duab.

Lawv suav nrog;

1. Voltage multimeter cim

Vim hais tias multimeters ntsuas ncaj qha tam sim no (DC) thiab alternating tam sim no (AC) voltage, lawv tso saib ntau tshaj ib tug voltage cim. AC voltage xaiv rau cov laus multimeters yog VAC. Cov neeg tsim khoom muab cov kab wavy saum toj V rau cov qauv tshiab los qhia AC voltage.

Rau DC voltage, manufacturers muab ib tug dotted kab nrog ib tug khoom kab saum toj no V. Yog hais tias koj xav ntsuas voltage nyob rau hauv millivolts, piv txwv li 1/1000 ntawm ib volt, tig lub dial rau mV.

2. Resistance multimeter cim

Lwm lub cim multimeter Circuit Court koj yuav tsum paub yog tsis kam. Lub multimeter xa cov hluav taws xob me me los ntawm ib lub voj voog los ntsuas qhov tsis kam. Lub Greek tsab ntawv Omega (Ohm) yog lub cim rau kev tiv thaiv ntawm ib tug multimeter. Koj yuav tsis pom cov kab saum toj no cov cim tiv thaiv vim cov meters tsis paub qhov txawv ntawm AC thiab DC tsis kam. (1)

3. Tam sim no multimeter cim 

Koj ntsuas tam sim no tib yam li koj ntsuas voltage. Nws tuaj yeem hloov pauv tam sim no (AC) lossis ncaj qha tam sim no (DC). Nco ntsoov tias ampere lossis ampere yog units ntawm tam sim no, uas piav qhia vim li cas lub cim multimeter rau tam sim no yog A.

Saib ntawm lub multimeter tam sim no, koj yuav pom tsab ntawv "A" nrog ib kab wavy saum nws. Qhov no yog alternating tam sim no (AC). Tsab ntawv "A" nrog ob kab-dashed thiab ruaj khov saum nws-sawv cev tam sim no (DC). Thaum ntsuas tam sim no nrog multimeter, cov kev xaiv muaj yog mA rau milliamps thiab µA rau microamps.

Jacks thiab nyees khawm

Txhua DMM los nrog ob txoj hauv kev, dub thiab liab. Tsis txhob xav tsis thoob yog tias koj lub multimeter muaj peb lossis plaub qhov txuas. Txhua yam koj sim txiav txim siab qhov twg koj txuas cov xov hlau.

Ntawm no yog kev siv ntawm txhua tus;

  • COM - common jack tsuas yog ib qho dub xwb. Qhov ntawd yog qhov uas cov hlau lead dub mus.
  • A - Qhov no yog qhov uas koj txuas cov xaim liab thaum ntsuas tam sim no txog 10 amperes.
  • mAmkA - Koj siv lub qhov (socket) no thaum ntsuas qhov ntsuas tam sim no tsawg dua li lub amp thaum lub multimeter muaj plaub lub qhov (socket).
  • mAwm - Qhov ntsuas qhov (socket) suav nrog qhov ntsuas hluav taws xob, qhov kub thiab qhov ntsuas tam sim no yog tias koj lub tshuab multimeter tuaj nrog peb lub qhov (socket).
  • VWM - Qhov no yog rau tag nrho lwm yam kev ntsuas tshwj tsis yog tam sim no.

Tau paub koj lub multimeter, tshwj xeeb tshaj yog nyob rau sab saum toj ntawm lub multimeter zaub. Koj puas pom ob lub nyees khawm - ib qho ntawm sab xis thiab ib qho ntawm sab laug?

  • ua haujlwm - Yuav kom txuag tau qhov chaw, cov tuam txhab lag luam tuaj yeem muab ob txoj haujlwm rau qee txoj haujlwm hu. Txhawm rau nkag mus rau cov haujlwm uas cim daj, nias lub pob Shift. Lub khawm hloov daj tuaj yeem lossis tsis muaj daim ntawv lo. (2)
  • Khaws - nias lub khawm tuav yog tias koj xav kom khov cov ntawv nyeem tam sim no rau kev siv tom qab.

Summing txog

Koj yuav tsum tsis muaj teeb meem kom tau txais kev nyeem DMM raug. Peb cia siab tias tom qab nyeem cov ntaub ntawv tseem ceeb no, koj xav paub zoo txog cov cim multimeter.

Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
