Fluke 120B seeria tööstuslikud ScopeMeter® käeshoitavad ostsilloskoobid
Lihtsustatud testimine, suurem ülevaade
Kompaktne ScopeMeter® 120B seeria on vastupidav ostsilloskoopide lahendus tööstuslike elektriliste ja elektromehaaniliste seadmete tõrkeotsinguks ja hoolduseks. See on tõeliselt integreeritud testimisvahend, mis koondab ostsilloskoobi, multimeetri ja kiire salvestaja funktsioonid ühte lihtsasti kasutatavasse seadmesse. ScopeMeter 120B seeria on integreeritud ka Fluke Connect® mobiilirakendusega ja FlukeView® for ScopeMeteri tarkvaraga, et võimaldada täiendavat koostööd, andmete analüüsi ja kriitilise testiteabe arhiveerimist.
Kiirem elektromehaaniline tõrkeotsing
Kiirem elektromehaaniline tõrkeotsing
Leidke kiiremini tõrkeid ja saate vastused, mida vajate süsteemide töövalmiduse säilitamiseks. Näidake lainekujusid Connect and View™ vallandamis- ja seadistustehnoloogiaga. Vaadake automaatselt seotud numbrilisi mõõtmisi, kasutades Fluke IntellaSet™ tehnoloogiat, ilma et peaksite tegema käsitsi mõõtmisseadistusi. Recorder Event Detect funktsiooniga tabatakse ja logitakse tabamatuid vahepealseid sündmusi lihtsaks vaatamiseks ja analüüsiks.
Connect-and-View™ vallandamine kohese ja stabiilse kuvamise jaoks.
Ostsilloskoobi kasutajad teavad, kui keeruline võib olla vallandamine. Vale seadistuse kasutamine võib viia ebastabiilse lainekuju jäädvustamiseni ja mõnikord isegi valede mõõteandmete saamiseni. Fluke'i ainulaadne Connect-and View™ vallandamistehnoloogia tunneb ära signaalimustrid ja seab automaatselt sisse õige vallandamise, et tagada stabiilne, usaldusväärne ja korratav ekraan.
Connect-and-View™ vallandamine on loodud töötama praktiliselt mis tahes signaaliga, sealhulgas mootorajamite ja juhtimissignaalidega - ilma parameetrite seadistamiseta või isegi ilma nuppu puudutamata. Signaalimuutused tuvastatakse koheselt ja seaded kohandatakse automaatselt, tagades stabiilse kuvamise isegi mitme katsepunkti kiire järjestikuse mõõtmise korral.
Connect-and-View™ vallandamine tagab kohese ja stabiilse kuvamise.
IntellaSet™/AutoReading
IntellaSet™/AutoReading
Fluke IntellaSet™-tehnoloogia Auto Readings funktsioon kasutab patenteeritud algoritme, et intelligentselt analüüsida mõõdetud lainekuju ja kuvada ekraanil automaatselt kõige sobivamad numbrilised mõõtmised, nii et saate vajalikud andmed lihtsamalt kui kunagi varem. Näiteks kui mõõdetud lainekuju on liinipinge signaal, kuvatakse automaatselt V rms ja Hz näitajad, kui aga mõõdetud lainekuju on ruutlaine, kuvatakse automaatselt V tipu ja Hz näitajad. Kasutades IntellaSet™-tehnoloogiat koos Connect and-View™ automaatse vallandamisega, võite olla kindel, et näete mitte ainult õiget lainekuju, vaid ka asjakohast numbrilist näitu. Ja seda kõike ilma nuppu puudutamata.
Harmooniate funktsioon mõõdab perioodilisi moonutusi
Harmoonilised signaalid on pinge, voolu või võimsuse siinuslainete perioodilised moonutused. Harmoonilised häired elektrijaotussüsteemides on sageli põhjustatud mittelineaarsetest koormustest, nagu näiteks lülitatud alalisvoolu toiteallikad ja reguleeritava kiirusega mootori ajamid. Harmoonilised signaalid võivad põhjustada trafode, juhtmete ja mootorite ülekuumenemist. Funktsioonis Harmoonilised mõõdab testimisvahend harmoonilisi sagedusi kuni 51. protsendini. Mõõdetakse sellega seotud andmeid, nagu alalisvoolu komponendid, THD (summaarne harmooniline moonutus) ja K-tegur, et anda täielik ülevaade teie koormuste elektrilisest seisundist.

Põhjalikud salvestusrežiimid aitavad leida katkendlikke rikkeid
Põhjalikud salvestusrežiimid aitavad leida katkendlikke rikkeid.
Kõige raskem on leida neid vigu, mis esinevad ainult üks kord - katkendlikud sündmused. Need võivad olla põhjustatud halbadest ühendustest, tolmust, mustusest, korrosioonist või lihtsalt katkisest juhtmestikust või pistikutest. Ka muud tegurid, nagu võrgukatkestused ja -langused või mootori käivitamine ja seiskamine, võivad põhjustada katkendlikke sündmusi, mis põhjustavad seadmete väljalülitamist. Kui need sündmused toimuvad, ei pruugi te seda näha. Kuid teie Fluke ScopeMeter Test Tool näeb seda.
Saate kas joonistada minimaalse ja maksimaalse tippväärtuse mõõtmisväärtused või salvestada lainekuju jälg. Ja tänu laiendatavale microSD-mälule saab salvestussessioone teha kuni 14 päeva jooksul. See salvesti on veelgi võimsam tänu Recorder Event Detect'ile, mis muudab katkendlike rikete tuvastamise ja logimise lihtsamaks kui kunagi varem. Lihtsalt seadke mõõteriistade või skoopiajälje künnis ja kõrvalekalded märgistatakse unikaalsete sündmustena. Te ei pea enam vigade kindlakstegemiseks andmemassiive läbi otsima ja saate kiiresti liikuda ühe märgistatud sündmuse juurest teise juurde, omades samal ajal juurdepääsu kogu andmekogumile.
