Txoj kev kho thiab tshuaj xyuas multimeters
Ua ntej, kho qhov tseem ceeb
Tshawb nrhiav cov teeb meem yuav tsum yog thawj sab nraud tom qab sab hauv, thawj qhov yooj yim tom qab qhov nyuaj, tag nrho rau hauv xoom, tsom rau kev tawg. Cov ntsiab lus tseem ceeb tuaj yeem kwv yees muab faib ua cov hauv qab no:
1. xav tias txoj cai cia siab rau kev nkag siab ncaj qha rau qhov ua rau muaj kev cuam tshuam rau kev txiav txim siab, los ntawm kev tshuaj xyuas saum npoo, tuaj yeem tsim tau, xws li cov xov hlau tawg, de-welding, luv-circuiting, fuse tube tawg, cov khoom tawg, mechanical puas tsuaj, luam tawm Circuit Court tooj liab ntawv ci warping thiab puas, thiab lwm yam .; tuaj yeem kov tawm ntawm lub roj teeb, resistors, transistors, kev sib xyaw ua ke ntawm qhov kub thiab txias ib puag ncig, koj tuaj yeem xa mus rau daim duab kos duab kom paub tias qhov kub thiab txias yog qhov ua rau siab heev. Tsis tas li ntawd, tes kuj tseem tuaj yeem kuaj xyuas seb cov khoom puas yog xoob, kev sib xyaw ua ke hauv ko taw lub raj yog khov kho, qhov hloov pauv tsis yog cassette; koj tuaj yeem hnov thiab hnov lub suab, tsw ntxhiab.
2. Kev ntsuas ntawm qhov voltage txoj kev 丈量各要害点的事情电压是否正常, 可较快找出阻碍点. Xws li ntsuas qhov A / D converter voltage, siv voltage.
3. luv luv-circuit txoj kev nyob rau hauv lub yav dhau los hais los xyuas lub A / D converter feem ntau yog txais nyob rau hauv lub short-circuit txoj kev, txoj kev no nyob rau hauv lub thaj tsis muaj zog thiab microelectronic seev siv ntau dua.
4. Tshem tawm qhov tsis txaus ntseeg los ntawm tag nrho lub tshuab lossis lub tshuab hluav taws xob kom tsis txhob qhib, yog tias cov teeb meem cuam tshuam, kev ua haujlwm ntawm cov teeb meem hauv kev txiav tawm. Txoj kev no yog ib qho tseem ceeb rau lub hav zoov ntawm luv luv-circuit Circuit Court ib puag ncig.
5. Kev ntsuas cov khoom thaum qhov kev cuam tshuam tau raug txo mus rau ib qho chaw lossis ob peb yam, tuaj yeem ntsuas hauv online lossis offline. Thaum tsim nyog, nrog kev hloov pauv zoo, yog tias qhov cuam tshuam tsis zoo, cov khoom tau ua phem.
6. Txoj kev tsis txaus siab siv tib neeg lub cev kom hnov qhov hluav taws xob raws li qhov teeb meem tsis txaus ntseeg, kev tshuaj xyuas cov kua siv lead ua kua ntawm qhov kev hloov ntawm ib puag ncig, feem ntau siv los xyuas cov khoom siv hluav taws xob thiab kev ua haujlwm ntawm lub tuam tsev yog npaj txhij.
