Yuav ua li cas sau cov kev ua txhaum tsis tu ncua nrog lub multimeter
Qee qhov multimeters tsis tsuas yog muaj lub luag haujlwm ntawm kev kaw 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, 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.
Yuav ua li cas khij lub sijhawm kaw nrog multimeter:
Lub sijhawm thaum kuaj pom qhov tsawg kawg nkaus thiab qhov siab tshaj plaws yog cov ntaub ntawv tseem ceeb heev rau kev txiav txim siab qhov ua rau muaj qhov tsis sib xws. Ib qho digital multimeter tuaj yeem khaws lub sijhawm ntawm kev pib sau thiab txuag qhov tsawg kawg nkaus, qhov siab tshaj plaws, lossis qhov nruab nrab ntawm qhov tsawg kawg nkaus / siab tshaj / nruab nrab cov ntaub ntawv hom. Yog li ntawd, txhua qhov kev txuag tsawg kawg nkaus, qhov siab tshaj plaws, thiab tus nqi nruab nrab muaj qhov sib thooj 'lub sij hawm stamp'.
Niaj hnub no, cov multimeters nrog digital tau los lossis muaj peev xwm khaws cia kuj muaj tib lub strip kaw ua haujlwm los ntawm cov khoos phis tawj lossis lawv lub cim xeeb. Yog hais tias tus multimeter digital muaj qhov tsawg kawg nkaus / siab tshaj / nruab nrab tus nqi kaw, zoo li daim ntawv kaw lus, cov multimeter digital kuj tseem nyeem cov ntawv nyeem ntawm qee lub sijhawm. Tab sis tsis zoo li daim ntawv kaw lus uas khaws cov ntawv nyeem ib leeg, kev nyeem ntawv yog piv nrog cov ntawv nyeem uas tau khaws tseg yav dhau los los txiav txim siab seb tus nqi puas siab dua tus nqi siab tshaj yav dhau los lossis qis dua tus nqi qis tshaj yav dhau los j. Yog tias muaj, qhov kev nyeem ntawv tshiab yuav hloov tus nqi khaws cia hauv cov ntawv sau siab lossis qis nyeem ntawv. Tom qab lub sijhawm kaw, koj tuaj yeem khaws cov txiaj ntsig ntawm cov cuab yeej cia no rau kev tso saib thiab saib qhov siab tshaj plaws thiab qhov tsawg kawg nkaus ntawm lub sijhawm kaw.
