Yuav siv lub multimeter li cas thiaj nrhiav tau cov teeb meem
1. Yuav ua li cas lub multimeter sau qhov tsis sib xws:
Siv qhov tsawg kawg nkaus / siab tshaj / nruab nrab cov ntaubntawv povthawj siv hom 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, thiab xyuas kom meej tias nws txuas nrog ua ntej ua haujlwm. min / max / nruab nrab muaj nuj nqi Ntsuas lub voj voog, txwv tsis pub qhov kev nyeem ntawv yam tsawg kawg nkaus yuav yog tus nqi ambient ua ntej qhov kev xeem coj txuas nrog. Qhov no cuam tshuam rau kev tsom xam ntawm cov ntaub ntawv kaw tom qab lub sijhawm kaw tau dhau mus. jActivate Min/Search Max/Average recording mode, qhov kev nyeem ntawv siab tshaj plaws yuav raug qhia rau ntawm multimeter zaub thiab lub beep yuav suab thaum kuaj pom tus nqi siab tshaj lossis yam tsawg kawg nkaus. xiab.
Qhov zoo ntawm qhov no yog tias thaum ua kom ntseeg tau tias digital multimeter yuav tsis raug cuam tshuam nrog thiab yuav tsis ua rau muaj kev nyab xeeb rau tib neeg, koj tuaj yeem tso cov digital multimeter nyob rau hauv qhov chaw rau kev ntsuas thiab tsom mus rau lwm yam haujlwm. Txhua lub sijhawm thaum lub sijhawm nkag mus, koj tuaj yeem saib cov ntawv nyeem tau khaws tseg, lossis ncua sijhawm nkag hom yam tsis tau tshem tawm cov ntawv nyeem.
2. Yuav ua li cas lub multimeter tsis tu ncua sau tsis sib xws:
Qee qhov multimeters tsis tsuas yog muaj qhov tsawg kawg nkaus / siab tshaj / nruab nrab cov ntaubntawv povthawj siv, tab sis kuj tseem muab cov haujlwm no nrog rau lwm txoj haujlwm hu ua AutoHOLD thiab lub cim xeeb loj dua los tsim Cov Txheej Txheem Logging. Gong Qing. Nws pib tuav feature hnov thaum lub teeb liab ntsuas tsis ruaj khov thiab thaum nws rov qab ruaj khov dua. Siv qhov pib-tuav muaj nuj nqi los ua kom pib thiab nres ntawm min / max kaw muaj nuj nqi tso cai rau DMM mus dhau qhov tsuas yog kuaj xyuas qhov ua txhaum uas tsim min lossis max qhov tseem ceeb.
Yog hais tias lub multimeter muaj ib tug infrared RS232 interface, qhov nruam kaw muaj nuj nqi yuav muaj zog dua, thiab nws yuav ua tau ib tug yooj yim txheej xwm collector xa cov ntaub ntawv sau los ntawm nws multimeter mus rau lub computer. Siv lub khoos phis tawj, cov ncauj lus kom ntxaws ntawm txhua qhov xwm txheej ruaj khov thiab tsis ruaj khov tuaj yeem ua tiav. Tsis tsuas yog koj tuaj yeem pom qhov tsawg kawg nkaus thiab siab tshaj qhov tseem ceeb ntawm txhua lub sijhawm ruaj khov thiab tsis ruaj khov, tab sis koj tuaj yeem pom thaum txhua lub sijhawm pib thiab xaus. Tsis tas li ntawd, cov nqi nruab nrab raug kaw rau txhua lub voj voog. Nyob rau tib lub sij hawm, nws muaj peev xwm dynamically ntes cov kev hloov pauv qauv ntawm voltage los yog tam sim no.
3. 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 tsis sib xws. Lub multimeter digital nyob rau hauv Min / Max / Nruab nrab kaw hom tuaj yeem khaws lub sijhawm nruab nrab ntawm thaum pib kaw thiab thaum twg qhov tsawg kawg nkaus, qhov siab tshaj plaws, lossis qhov nruab nrab tau txais kev cawmdim. Yog li ntawd, txhua qhov kev txuag tsawg kawg nkaus, qhov siab tshaj plaws thiab nruab nrab tus nqi muaj "lub sij hawm stamp" sib haum rau nws.
Tam sim no, digital multimeters nrog cov khoom siv digital lossis kev cia khoom tseem muaj tib lub strip kaw ua haujlwm los ntawm cov khoos phis tawj lossis lawv lub cim xeeb. Yog tias DMM muaj Min / Max / Nruab Nrab kaw hom, zoo li daim kab xev kaw, DMM kuj siv sijhawm nyeem ntawv ib ntus. Tab sis tsis txhob txuag kev nyeem ntawv nrog ib daim kab xev, qhov kev nyeem ntawv yog muab piv rau qhov kev nyeem ntawv 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 raug hloov pauv. tus nqi Ameslikas tuav nyob rau hauv lub siab los yog tsawg nyeem ntawv sau npe. Tom qab kaw rau ib lub sijhawm, koj tuaj yeem nco qab cov txiaj ntsig ntawm cov ntawv sau npe no rau kev tso saib, thiab saib qhov siab tshaj plaws thiab qhov tsawg kawg nkaus thaum lub sijhawm kaw.
