Thaum siv digital multimeters, koj yuav tsum tau ua haujlwm nrog ntau yam haujlwm xws li ntsuas qhov voltage, tsis kam, thiab tam sim no. Rau txhua qhov kev ua haujlwm no, muaj ntau hom kev teeb tsa. Txhawm rau txiav txim siab cov chaw no, koj yuav tsum muaj kev nkag siab zoo ntawm cov cim multimeter. Hauv tsab xov xwm no, peb yuav tham tshwj xeeb txog multimeter voltage cim.

Thaum nws los txog rau multimeter voltage cim, muaj peb hom cim koj yuav tsum paub. Niaj hnub nimno digital multimeters muaj cov cim rau AC voltage, DC voltage, thiab multivolts.

Ntau hom units nyob rau hauv ib tug multimeter

Ua ntej peb delve rau hauv cov cim multimeter, muaj ob peb lwm yam subtopics uas peb yuav tsum tau tham. Ib tug ntawm lawv yog ntau hom units.

Tau hais tias, txawm tias koj siv DMM lossis analog multimeter, koj xav tau kev paub dav dav ntawm chav nyob thiab kev faib. Txij li thaum peb tab tom tham txog qhov voltage, peb yuav khaws cov lus piav qhia ntawm chav tsev rau qhov voltage nkaus xwb. Tab sis nco ntsoov, koj tuaj yeem siv tib txoj kev xav rau tam sim no thiab kev tawm tsam.

Peb siv V, tseem hu ua volts, los sawv cev voltage. V yog thawj chav tsev, thiab ntawm no yog cov subunits.

K rau kg: 1kV sib npaug 1000V

M rau mega: 1MV sib npaug 1000kV

m rau milli: 1 mV sib npaug 0.001 V

µ rau kg: 1kV sib npaug 0.000001V (1)

Cim

Txawm hais tias koj siv analog multimeter lossis digital multimeter, koj yuav ntsib ntau lub cim sib txawv. Yog li ntawm no yog qee cov cim koj yuav ntsib thaum siv analog lossis digital multimeter.

  • 1: Tuav khawm
  • 2: AC voltage
  • 3: hertz
  • 4: DC voltage
  • 5: D.C
  • 6: Tam sim no Jack
  • 7: Common Jack
  • 8: Ntau khawm
  • 9: Brightness khawm
  • 10: OFF.
  • 11: Ohm
  • 12: Diode xeem
  • 13: Lwm qhov tam sim no
  • 14: Liab Jack

Multimeter voltage cim

Lub multimeter (2) muaj peb voltage cim. Thaum ntsuas qhov voltage nrog lub multimeter, koj yuav tsum paub cov cim no. Yog li ntawm no yog qee cov ntsiab lus hais txog lawv.

AC voltage

Thaum koj ntsuas alternating tam sim no (AC), koj yuav tsum teem lub multimeter rau alternating voltage. Lub wavy kab saum toj V sawv cev rau AC voltage. Hauv cov qauv qub, cov ntawv VAC sawv ntsug rau AC voltage.

DC voltage

Koj tuaj yeem siv qhov teeb tsa DC voltage los ntsuas DC voltage. Cov khoom thiab dotted kab saum toj V qhia DC voltage.(3)

Multivolts

Nrog rau kev teeb tsa Multivolts, koj tuaj yeem tshawb xyuas AC thiab DC voltage ntau dua. Ib kab wavy saum tsab ntawv mV sawv cev rau cov multivolts.

Summing txog

Los ntawm cov ntawv tshaj tawm saum toj no, peb cia siab tias koj tuaj yeem tau txais lub tswv yim zoo ntawm multimeter voltage cim.. Yog li lwm zaus koj siv multimeter los ntsuas qhov voltage, koj yuav tsis nkag siab.
