5 txoj hauv kev los nrhiav qhov yuam kev nrog multimeters
⒈ txoj kev xav
Siv qhov kev nkag siab los txiav txim ncaj qha rau qhov ua rau tsis ua haujlwm. Los ntawm kev tshuaj xyuas qhov muag, koj tuaj yeem pom xws li kev sib txuas, desoldering, luv luv Circuit Court, tawg fuse tube, burnt Cheebtsam, mechanical puas, tooj liab ntawv nyiaj lifting thiab puas nyob rau hauv lub luam Circuit Court, thiab lwm yam.; Koj tuaj yeem kov qhov kub thiab txias ntawm lub roj teeb, resistors, transistors, thiab kev sib xyaw ua ke, thiab koj tuaj yeem xa mus rau daim duab kos duab kom paub seb yog vim li cas rau qhov kub tsis txawv txav. Tsis tas li ntawd, los ntawm txhais tes, koj tuaj yeem tshawb xyuas seb cov khoom puas yog xoob, seb cov pins sib xyaw ua ke tau ruaj khov, thiab seb qhov hloov pauv hloov yog daig; koj tuaj yeem hnov thiab hnov txog seb puas muaj suab txawv txav thiab tsw.
⒉ voltage ntsuas txoj kev
Kev ntsuas seb qhov ua haujlwm voltage ntawm txhua qhov tseem ceeb yog qhov qub tuaj yeem tshawb pom qhov yuam kev. Xws li ntsuas qhov ua haujlwm voltage thiab siv voltage ntawm A / D converter.
⒊ Short circuit method
Nyob rau hauv txoj kev tshawb xyuas A / D converter tau hais los saum no, feem ntau siv txoj kev luv luv. Txoj kev no feem ntau siv thaum kho cov twj tsis muaj zog thiab micro-hluav taws xob.
⒋ txoj kev tawg ntawm lub voj voog
Tshem tawm qhov tsis txaus ntseeg los ntawm tag nrho lub tshuab lossis lub tshuab hluav taws xob. Yog hais tias qhov txhaum ploj mus, nws txhais tau hais tias qhov txhaum nyob rau hauv lub disconnected Circuit Court. Cov qauv no feem ntau haum rau qhov xwm txheej uas muaj qhov luv luv hauv Circuit Court.
5. Kev ntsuas cov txheej txheem
Thaum qhov ua txhaum tau nqaim mus rau ib lossis ob peb yam, nws tuaj yeem ntsuas hauv online lossis offline. Yog tias tsim nyog, hloov nws nrog qhov zoo. Yog tias qhov txhaum ploj mus, cov khoom tawg.
Taw qhia txog qhov tseeb ntawm digital multimeters
Qhov tseeb ntawm digital multimeter yog kev sib xyaw ua ke ntawm cov txheej txheem thiab qhov tsis raug hauv qhov ntsuas ntsuas. Nws qhia txog qib kev pom zoo ntawm tus nqi ntsuas thiab tus nqi tseeb, thiab tseem qhia txog qhov loj ntawm qhov ntsuas qhov yuam kev. Feem ntau hais lus, qhov raug siab dua, qhov me me ntawm qhov ntsuas qhov yuam kev, thiab rov ua dua.
Digital multimeters yog qhov tseeb dua li analog analog multimeters. Qhov tseeb ntawm multimeter yog qhov taw qhia tseem ceeb heev. Nws qhia txog qhov zoo thiab kev muaj peev xwm ntawm multimeter. Nws yog ib qho nyuaj rau ib tug multimeter nrog cov neeg tsis zoo los qhia tus nqi tiag tiag, uas yuav yooj yim ua rau kev txiav txim siab tsis zoo hauv kev ntsuas.
