Txoj kev tshawb xyuas hluav taws xob tsis raug nrog lub multimeter
Yuav ua li cas siv lub multimeter los kuaj thiab kuaj xyuas qhov tsis raug ntawm hluav taws xob, nws yog ib qho nyuaj rau kev ntes cov hluav taws xob tsis zoo thaum muaj qhov txhaum, uas ntxiv cov teeb meem loj rau kev tshawb nrhiav.
Muaj ntau cov cuab yeej kuaj xyuas uas tuaj yeem ua rau kev kuaj mob tsis sib xws yooj yim.
Cov khoom siv no suav nrog cov teeb liab tsom xam thiab cov oscilloscopes digital, nrog rau cov khoom siv tes tuav tau yooj yim thiab yooj yim siv. Digital multimeters kuj xav tau kev ntsuas thiab sau cov peev xwm rau kev ntsuas kev ua haujlwm (AC voltage, DC voltage, thiab ntsuas kev tiv thaiv), thiab tuaj yeem ua ke nrog cov qauv txheej txheem txhawm rau txheeb xyuas qhov tsis sib haum xeeb.
Yav dhau los, tib neeg siv cov tshuab ntawv daim kab xev kaw kom tsis tu ncua cov ntaub ntawv voltage lossis tam sim no. Thaum lub sij hawm ua hauj lwm, nws yog tsim nyog los txuas voltage rau lub input los yog clamp lub tam sim no sensor ntawm cov hlau. Lub kaw lus yuav luam tawm qhov kev hloov pauv ntawm qhov hluav taws xob lossis tam sim no ntawm daim ntawv daim kab xev, thiab qhov ntev tshaj plaws uas tau sau tseg yog nyob ntawm tus nqi ntawm daim ntawv.
1, Nruam faults kaw los ntawm ib tug multimeter
Siv qhov tsawg kawg nkaus / siab tshaj / nruab nrab tus nqi sau hom ntawm multimeter, xaiv qhov kev ua haujlwm (AC voltage, DC voltage, tsis kam, AC tam sim no, DC tam sim no, thiab zaus) raws li cov khoom ntsuas, xyuas kom meej tias qhov ntsuas hluav taws xob txuas ua ntej ua kom qhov tsawg kawg nkaus / siab tshaj / nruab nrab tus nqi muaj nuj nqi. Txwv tsis pub, qhov tsawg kawg nkaus tus nqi nyeem ntawv yuav ib txwm yog tus nqi ib puag ncig ua ntej cov kab xeem txuas nrog.
Qhov no yuav cuam tshuam rau kev tsom xam ntawm cov ntaub ntawv kaw tom qab qhov kawg ntawm lub sijhawm kaw, qhib qhov tsawg kawg nkaus / siab tshaj / nruab nrab tus nqi kaw, thiab lub vijtsam multimeter yuav qhia qhov kev nyeem ntawv siab tshaj plaws, thiab lub suab nrov yuav nrov thaum tus nqi siab tshaj lossis tsawg kawg nkaus. kuaj pom.
Qhov zoo: Thaum ua kom ntseeg tau tias lub tshuab digital multimeter tsis cuam tshuam nrog thiab tsis ua rau muaj kev nyab xeeb rau tib neeg, lub tshuab digital multimeter tuaj yeem tso rau hauv qhov chaw rau kev ntsuas thiab tsom mus rau lwm yam haujlwm. Txhua lub sijhawm thaum lub voj voog kaw, koj tuaj yeem saib cov ntawv nyeem tau khaws tseg lossis nres lub kaw lus yam tsis tas yuav rho tawm cov ntawv nyeem.
2, Lub multimeter tsis tu ncua sau cov kev tsis sib xws
Qee qhov multimeters tsis tsuas yog muaj lub luag haujlwm ntawm kev sau qhov tsawg kawg nkaus / siab tshaj / nruab nrab qhov tseem ceeb, tab sis kuj tseem muab cov haujlwm no nrog lwm txoj haujlwm hu ua AutoHOLD thiab lub cim xeeb loj dua los txhim kho Event Logging muaj nuj nqi.
Lub tshuab ua haujlwm tsis siv neeg tuaj yeem nkag siab thaum ntsuas lub teeb liab tsis ruaj khov thiab thaum nws ruaj khov dua. Los ntawm kev siv lub tshuab tuav tsis siv neeg los ua kom pib thiab nres ntawm qhov tsawg kawg nkaus / qhov siab tshaj qhov teev cov nqi, cov multimeter digital tsis txwv rau kev kuaj xyuas qhov ua txhaum uas tsim qhov tsawg kawg nkaus lossis qhov siab tshaj plaws.
Yog hais tias lub multimeter muaj ib qho infrared RS232 interface, cov ntaub ntawv txuas mus ntxiv yuav muaj zog dua thiab tuaj yeem dhau los ua ib qho kev tshwm sim yooj yim, xa cov ntaub ntawv sau los ntawm multimeter mus rau lub computer.
Los ntawm kev siv cov khoos phis tawj, cov ncauj lus kom ntxaws tuaj yeem ua tiav ntawm txhua qhov xwm txheej ruaj khov thiab tsis ruaj khov.
Tsis tsuas yog koj tuaj yeem saib qhov tsawg kawg nkaus thiab siab tshaj qhov tseem ceeb hauv txhua lub voj voog ruaj khov thiab tsis ruaj khov, tab sis koj tuaj yeem saib lub sijhawm pib thiab xaus ntawm txhua lub voj voog. Tsis tas li ntawd, sau tus nqi nruab nrab rau txhua lub voj voog. Nyob rau tib lub sijhawm, nws tuaj yeem kuaj pom qhov hloov pauv ntawm qhov voltage lossis tam sim no Khiav daim ntawv.
