Yuav ua li cas ib tug multimeter sau tsis sib xws faults
Siv lub multimeter min / max / nruab nrab kaw hom, xaiv lub zog tsim nyog (AC voltage, DC voltage, tsis kam, AC tam sim no, DC tam sim no, thiab zaus) raws li cov khoom ntsuas, thiab xyuas kom meej tias qhov ntsuas hluav taws xob txuas ua ntej ua kom lub min / max / nruab nrab muaj nuj nqi, txwv tsis pub qhov kev nyeem ntawv yam tsawg kawg nkaus yuav ib txwm yog tus nqi ambient ua ntej cov kab xeem txuas nrog. Qhov no yuav cuam tshuam rau kev tsom xam ntawm cov ntaub ntawv kaw tom qab lub sijhawm kaw tau dhau mus. j Ua kom lub min / tshawb nrhiav max / nruab nrab kaw hom yuav qhia qhov kev nyeem ntawv siab tshaj plaws ntawm cov khoom siv multimeter thiab yuav ua suab nrov thaum kuaj pom tus nqi siab tshaj lossis yam tsawg kawg nkaus.
Qhov kom zoo dua ntawm qhov no yog tias koj tuaj yeem tso cov digital multimeter nyob rau hauv qhov chaw los ntsuas thiab mloog zoo rau lwm yam dej num thaum koj xyuas kom meej tias nws tsis cuam tshuam nrog thiab tsis ua rau muaj kev phom sij rau leej twg. 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 multimeters tsis tu ncua sau qhov tsis sib xws.
Qee qhov multimeters tsis tsuas yog muaj min / max / nruab nrab cov ntaub ntawv kaw lus, tab sis kuj tseem muab cov haujlwm no nrog rau lwm txoj haujlwm hu ua AutoHOLD2 thiab lub cim xeeb loj dua los tsim EventLogging muaj nuj nqi. AutoHOLD muaj nuj nqi nkag siab thaum ntsuas 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 min / max logging muaj nuj nqi, cov multimeter digital tsis txwv rau kev kuaj xyuas qhov ua txhaum uas tsim qhov tsawg kawg nkaus lossis siab tshaj qhov tseem ceeb.
Yog hais tias lub multimeter muaj ib qho infrared RS232 interface, qhov txuas txuas ntxiv ua haujlwm yuav muaj zog dua, thiab tuaj yeem dhau los ua ib qho kev tshwm sim yooj yim los hloov cov ntaub ntawv sau los ntawm nws cov multimeter mus rau lub computer. Siv lub computer, txhua qhov xwm txheej ruaj khov thiab tsis ruaj khov tuaj yeem txheeb xyuas kom meej. Koj tuaj yeem saib tsis yog qhov tsawg kawg nkaus thiab qhov siab tshaj plaws 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. Tus nqi nruab nrab ntawm txhua lub voj voog tseem raug kaw. Nyob rau tib lub sijhawm, koj tuaj yeem tshawb xyuas qhov sib txawv ntawm qhov voltage lossis tam sim no hloov pauv.
Yuav ua li cas lub multimeter cim lub sij hawm kaw.
Lub sijhawm 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 nyob rau hauv min / max / nruab nrab kaw hom tuaj yeem khaws lub sijhawm ntawm qhov pib sau thiab txuag qhov tsawg kawg nkaus tshiab, siab tshaj lossis nruab nrab tus nqi. Yog li, txhua qhov kev txuag tsawg kawg nkaus, qhov siab tshaj plaws thiab nruab nrab tus nqi muaj qhov sib thooj "lub sij hawm stamp".
Niaj hnub no, cov multimeters digital nrog cov khoom siv digital los yog cov haujlwm khaws cia muaj tib lub bandwidth kaw ua haujlwm los ntawm lub computer lossis nws lub cim xeeb. Yog hais tias cov multimeter muaj ib min / max / nruab nrab kaw hom muaj nuj nqi xub xub, thiab daim kab xev recorder, cov multimeter kuj nyob rau hauv ib tug tej lub sij hawm nyeem ntawv harness input nyeem. Txawm li cas los xij, tsis zoo li daim ntawv kaw lus uas txuag tus neeg nyeem ntawv, cov ntawv nyeem tau muab piv rau cov ntawv nyeem uas tau khaws tseg yav dhau los los txiav txim siab tias tus nqi siab dua qhov siab tshaj plaws yav dhau los lossis qis dua qhov tsawg kawg nkaus dhau los. jYog li ntawd, qhov kev nyeem ntawv tshiab yuav raug siv los hloov tus nqi qub uas tau khaws tseg hauv cov ntawv sau siab lossis qis nyeem ntawv. Tom qab ib lub sij hawm ntawm kev txiav, koj tuaj yeem hu rau qhov tseem ceeb clamored hauv cov npe no rau cov zaub kom pom qhov siab tshaj plaws thiab qhov tsawg kawg nkaus thaum lub sij hawm nkag.
