Kev daws teeb meem Fluke multimeters tuaj yeem muab faib ua ntau txoj hauv kev?
Multimeters tuaj yeem siv los ntsuas tsis yog qhov kev tiv thaiv ntawm cov khoom raug ntsuas, AC thiab DC voltages tab sis kuj DC voltages. Txawm hais tias qee qhov multimeters tuaj yeem ntsuas qhov tseem ceeb ntawm cov transistors thiab cov capacitance ntawm capacitor. Ua tiav kev siv cov multimeter yog ib qho ntawm cov kev txawj ntse tshaj plaws ntawm kev siv tshuab hluav taws xob. Multimeters muaj xws li pointer multimeters thiab digital multimeters. Pointer multimeter yog ib qho kev ntsuas ntau yam nrog lub taub hau ' meter ' raws li cov ntsiab lus tseem ceeb, thiab ntsuas tus nqi yog nyeem los ntawm tus pointer ntawm lub taub hau ntsuas. Digital multimeter ntsuas tus nqi los ntawm LCD zaub ncaj qha nyob rau hauv daim ntawv ntawm cov zaub, nyeem tau yooj yim, ib txhia kuj nrog lub suab prompts. Multimeter yog ib lub taub hau, teeb ntawm voltmeter, ammeter thiab ohmmeter hauv ib qho cuab yeej. Multimeter tsis ua hauj lwm zoo li multi-factorial, thiab ntsib teeb meem nrog randomness ntawm loj, tsis ntau dhau mus ua raws, kho yog nyuaj. Cov neeg kho kom zoo yuav ua haujlwm tau ntau xyoo hauv kev sib sau ua ke ntawm qee qhov kev kho kom haum rau koj siv. Fluke multimeter troubleshooting txoj kev tuaj yeem muab faib ua hom hauv qab no:
(1) Kev ntsuas qhov ntsuas hluav taws xob los ntsuas cov ntsiab lus tseem ceeb ntawm kev khiav hauj lwm qhov hluav taws xob yog qhov qub, koj tuaj yeem tshawb pom qhov tsis ua haujlwm sai. Xws li ntsuas qhov ua haujlwm voltage ntawm A / D converter, siv voltage, thiab lwm yam.
(2) txoj kev xav los ntawm kev tsim txiaj ntawm kev nkag siab ncaj qha mus rau qhov ua tsis tiav ntawm kev txiav txim siab, los ntawm cov tsos ntawm kev soj ntsuam, tuaj yeem pom xws li cov xov hlau tawg, desoldering, luv-circuit lap, fuse tube tawg, hlawv cov khoom, mechanical puas tsuaj, tooj liab ntawv ci ntawm cov luam tawm Circuit Court warping thiab tawg, thiab lwm yam .; koj tuaj yeem kov tawm ntawm lub roj teeb, resistors, transistors, kev sib xyaw ua ke ntawm qhov kub thiab txias, koj tuaj yeem xa mus rau daim duab kos duab kom paub cov laj thawj ntawm qhov kub thiab txias qhov txawv txav. Tsis tas li ntawd, tes kuj tseem tuaj yeem kuaj xyuas seb cov khoom puas yog xoob, seb qhov sib txuas ntawm lub ko taw ko taw lub raj puas tau ntxig rau ruaj, seb qhov hloov pauv hloov yog cassette; tuaj yeem hnov thiab hnov lub suab, tsw.
(3) Tshem tawm qhov tsis txaus ntseeg los ntawm tag nrho lub tshuab lossis chav tsev hauv Circuit Court disconnect, yog tias qhov txhaum ploj mus, hais tias qhov txhaum hauv kev txiav tawm. Txoj kev no tsuas yog tsim nyog rau lub neej ntawm luv luv Circuit Court.
(4) luv luv-circuit txoj kev nyob rau hauv lub yav dhau los hais txoj kev ntawm kev kuaj A / D converter feem ntau yog siv nyob rau hauv lub short-circuit txoj kev, txoj kev no yog siv nyob rau hauv kev kho cov tsis muaj zog thiab microelectronic instruments.
(5) Kev ntsuas cov khoom thaum qhov kev ua txhaum tau nqaim mus rau ib qho chaw lossis ob peb yam, tuaj yeem ntsuas hauv online lossis offline. Yog tias tsim nyog, hloov lawv nrog cov khoom zoo, thiab yog tias qhov txhaum ploj mus, cov khoom tsis zoo.
(6) Kev cuam tshuam txoj kev siv tib neeg lub cev induced voltage raws li lub teeb liab cuam tshuam, soj ntsuam cov kev hloov ntawm cov kua siv lead ua kua zaub, feem ntau siv los xyuas cov input Circuit Court thiab tso saib ib feem tsis zoo.
