Pointer multimeter siv ceev faj
Multimeter, tseem hu ua multimeter, multimeter, lossis multimeter, muab faib ua pointer multimeters thiab digital multimeters. Nws yog multifunctional thiab ntau yam ntsuas ntsuas. Feem ntau, multimeter tuaj yeem ntsuas DC tam sim no, DC voltage, AC tam sim no, AC voltage, tsis kam, thiab suab qib. Qee qhov tseem tuaj yeem ntsuas AC tam sim no, capacitance, inductance, thiab qee qhov ntsuas ntawm semiconductors
Thaum ua qhov ntsuas hluav taws xob siab lossis thaum muaj hluav taws xob siab nyob ze ntawm qhov ntsuas ntsuas, nws yog ib qho tseem ceeb uas yuav tsum tau xyuam xim rau tus kheej thiab ntsuas kev nyab xeeb. Thaum ntsuas qhov hluav taws xob siab thiab siab tam sim no, nws yog nruj me ntsis txwv tsis pub hloov qhov ntau thiab qis thaum nyob, txwv tsis pub nws yuav ua rau kev hloov pauv hloov. Tsis tas li ntawd, tom qab siv lub multimeter, nws yog qhov zoo tshaj plaws los tso qhov hloov pauv hloov hauv nruab nrab lossis AC voltage * siab iav kom tsis txhob muaj kev puas tsuaj rau lub multimeter vim tsis saib xyuas thaum ntsuas tom ntej.
Tom qab siv lub multimeter, tsis txhob tig rau ntawm lub iav tiv thaiv vim tias muaj lub roj teeb hauv lub ntsuas kom tsis txhob ua yuam kev ua rau ob lub meter tuav sib tsoo thiab luv luv, uas tuaj yeem haus lub roj teeb. Nws yog qhov zoo tshaj plaws los tso qhov hloov pauv hloov hauv * siab AC voltage iav lossis nruab nrab iav.
Thaum ntsuas cov khoom siv nrog qhov ntau ntawm ohm, nws tsis raug tso cai kov cov hlau xaus ntawm ob qhov kev sojntsuam nrog ob txhais tes tib lub sijhawm kom tsis txhob ntsuas qhov yuam kev tshwm sim los ntawm tib neeg tsis kam.
Thaum ntsuas AC voltage, yuav tsum tau them nyiaj mloog mus rau qhov zaus thiab waveform ntawm AC lub zog. MF47 multimeter tsuas tau txais qhov tseeb qhov tseeb thaum ntsuas sine yoj AC lub zog nrog ntau zaus ntawm 45-65Hz.
Rau ib lub multimeter uas tsis tau siv ntev, lub roj teeb yuav tsum tau muab tshem tawm raws sij hawm kom tsis txhob muaj cov electrolyte leaked tom qab lub roj teeb deteriorates los ntawm corroding Circuit Court board ntawm lub multimeter.
Lub multimeter yog ib qho kev ntsuas siab, thiab yuav tsum tau muab cia kom deb ntawm qhov muaj zog sib nqus. Nws yuav tsum tau ua tib zoo saib xyuas thiab tsis txhob muaj zog vibrations thiab kev sib tsoo ntau li ntau tau.
