Yuav ua li cas kuaj thiab daws teeb meem hluav taws xob tsis raug nrog Multimeter
Yuav siv nws li cas los kuaj thiab txheeb xyuas qhov txhaum ib txwm ua haujlwm nyuaj, vim tias nws nyuaj rau kev ntes cov hluav taws xob tsis zoo thaum muaj teeb meem tshwm sim, uas ntxiv qhov nyuaj heev rau peb qhov kev tshawb nrhiav.
Muaj ntau ntau yam khoom siv ntsuas uas tuaj yeem ua rau kev kuaj mob tsis sib xws yooj yim. Cov cuab yeej no suav nrog cov teeb liab tsom xam thiab cov khoom siv digital, nrog rau cov khoom siv tes tuav tau yooj yim thiab cov multimeters digital. Nyob rau hauv cov nqe lus ntawm kev ntsuas kev ua haujlwm (AC voltage, DC voltage, thiab kev ntsuas tsis kam), lawv kuj xav tau kev ntsuas ntsuas ntsuas. Los ntawm kev sib txuas cov rooj sib tham, multimeter tuaj yeem kuaj xyuas qhov tsis raug ntawm qhov tsis sib xws.
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 sijhawm ua haujlwm, nws yog qhov tsim nyog los txuas qhov hluav taws xob mus rau lub tswv yim lossis clamp tam sim no ntawm cov hlau. Lub kaw lus yuav luam tawm cov kev hloov pauv ntawm qhov hluav taws xob lossis tam sim no ntawm daim ntawv daim kab xev, thiab qhov ntev tshaj plaws ntawm cov ntaub ntawv yog nyob ntawm tus nqi ntawm daim ntawv ntawm daim ntawv swb.
Yuav ua li cas sau qhov tsis sib xws nrog lub multimeter
Siv qhov tsawg kawg nkaus / siab tshaj / nruab nrab tus nqi sau hom ntawm multimeter, xaiv lub zog sib xws (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 qhib 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. 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 hom, thiab cov khoom siv multimeter yuav qhia qhov kev nyeem ntawv siab tshaj plaws. Thaum kuaj pom qhov siab tshaj plaws lossis qhov tsawg kawg nkaus, lub suab nrov yuav raug tso tawm.
Qhov zoo ntawm qhov no yog tias, thaum ua kom ntseeg tau tias cov digital multimeter tsis cuam tshuam nrog thiab tsis muaj kev nyab xeeb rau leej twg, nws 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.
Yuav ua li cas tsis tu ncua sau qhov tsis sib xws nrog lub multimeter
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 rau lwm txoj haujlwm hu ua AutoHOLD thiab lub cim xeeb loj dua, tsim lub zog ntawm Event Logging. Kev saib xyuas 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 nws pib tuav muaj nuj nqi los ua kom pib thiab nres ntawm qhov tsawg kawg nkaus / siab tshaj tus nqi sau tseg, cov multimeter digital tsis txwv rau kev kuaj xyuas qhov ua txhaum uas tsim kom muaj qhov tsawg kawg nkaus lossis qhov siab tshaj plaws.
Yog hais tias lub multimeter muaj ib qho infrared RS232 interface, qhov txuas txuas ntxiv ua haujlwm yuav muaj zog dua, thiab nws tuaj yeem dhau los ua ib qho kev tshwm sim yooj yim los 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. Koj tuaj yeem tsis tsuas saib qhov tsawg kawg nkaus thiab siab tshaj qhov tseem ceeb nyob rau hauv txhua lub voj voog ruaj khov thiab tsis ruaj khov, tab sis kuj yog 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 tshawb xyuas qhov sib txawv ntawm qhov voltage lossis tam sim no hloov pauv.
