Yuav ua li cas txheeb xyuas kab qhov taw tes ntawm kev ua tsis tiav siv lub tshuab digital multimeter
1. Kev kuaj pom.
Koj tuaj yeem kov lub roj teeb, resistor, transistor, integrated block kub nce siab heev. Yog hais tias lub roj teeb uas nyuam qhuav thauj khoom yog kub, nws txhais tau hais tias lub Circuit Court yuav luv luv. Tsis tas li ntawd, nws yuav tsum tau soj ntsuam seb lub Circuit Court puas, desoldering, mechanical puas thiab lwm yam.
2, waveform tsom xam.
Nrog lub tshuab hluav taws xob oscilloscope los soj ntsuam lub voj voog hluav taws xob hluav taws xob, lub sijhawm ua haujlwm, lub sijhawm (ntau zaus) thiab lwm yam.
Piv txwv li, xws li ntsuas seb lub moos oscillator kev co, yog hais tias lub oscillator tsis muaj cov zis, qhia tau hais tias lub internal inverter puas lawm, nws kuj yog ib tug sab nraud tivthaiv qhib Circuit Court.
3, ntsuas qhov ntsuas qhov ntsuas.
Cheebtsam nyob rau hauv lub Scope ntawm qhov txhaum, kev ntsuas hauv internet los yog offline ntsuas, parameter qhov tseem ceeb yuav tsum tau soj ntsuam. Rau kev ntsuas kev tiv thaiv online, yuav tsum xav txog qhov cuam tshuam ntawm cov khoom sib txuas nrog nws.
4, zais qhov yuam kev tshem tawm.
Hidden fault hais txog qhov txhaum yog muab zais, qhov ntsuas yog qee zaum zoo thiab qee zaum ua txhaum. Xws li kev ua tsis tiav yog qhov nyuaj dua, feem ntau ua rau muaj kev sib koom ua ke ntawm cov pob qij txha, xoob, xoob txuas, kev sib cuag tsis zoo nrog kev hloov pauv, cov khoom siv tsis ruaj khov, cov hlau lead yuav tawg thiab lwm yam. Tsis tas li ntawd, kuj suav nrog qee yam sab nraud tshwm sim los ntawm. Xws li kub ambient kub, cov av noo ntau dhau los yog muaj zog cuam tshuam cov teeb liab nyob ze thiab lwm yam.
5, kuaj xyuas qhov ua haujlwm voltage ntawm txhua qib.
Tshawb xyuas qhov ua haujlwm voltage ntawm txhua qhov chaw, thiab sib piv nrog tus nqi ib txwm muaj.
Ua ntej tshaj plaws, qhov tseeb ntawm qhov siv hluav taws xob yuav tsum tau ua kom ntseeg tau, nws yog qhov zoo tshaj plaws los siv ib daim ntawm tib cov qauv los yog cov digital multimeter zoo sib xws rau kev ntsuas thiab sib piv.
