Daim ntawv thov tshiab digital multimeter hauv kev lag luam
Raws li ib qho ntawm cov khoom lag luam tsis tseem ceeb hauv kev ntsuas hluav taws xob, digital multimeter muaj qhov dav tshaj plaws ntawm kev siv. Lub multimeter digital yog cov ntsuas ntsuas uas siv lub hauv paus ntsiab lus ntawm analog / digital hloov pauv hloov cov ntaub ntawv ntsuas mus rau hauv cov lej digital thiab tso saib cov txiaj ntsig ntsuas hauv daim ntawv digital. Piv nrog rau lub pointer multimeter, tiam tshiab ntawm cov multimeter muaj qhov zoo ntawm high precision, ceev ceev, loj input impedance, digital zaub, nyeem kom raug, muaj zog tiv thaiv kev cuam tshuam, thiab qib siab ntawm kev ntsuas automation, yog li nws yog dav siv. thiab nyiam los ntawm engineers.
Troubleshooting pab engineers daws teeb meem
Cov ntaub ntawv ntsuas tus nqi ntawm multimeter mus txog 50k / s yog tam sim no qhov ntsuas siab tshaj plaws hauv kev lag luam. Siv cov yam ntxwv no, cov txheej txheem txuas ntxiv uas yav dhau los nyuaj rau kev ntes nrog qeeb nyeem ntawv digital multimeters tuaj yeem ntes tau tag nrho.
Hauv kev tsim hluav taws xob, kev ua tsis tiav tam sim ntawd feem ntau tshwm sim hauv cov khoom kab. Nws yog ib qho tseem ceeb heev rau cov engineers kom paub qhov ua rau tsis ua hauj lwm thiab daws qhov teeb meem raws sij hawm. Piv txwv li, DVD designers feem ntau muaj teeb meem ntawm lub hwj chim mov burnout nyob rau hauv tus txheej txheem ntawm debugging khoom, uas ua rau ib tug ntau ntawm inconvenience rau cov khoom ntau lawm. Siv cov thev naus laus zis A/D tshiab, lub tshuab multimeter tuaj yeem ua tiav qhov kev nyeem ntawv ceev ntawm 50, 000 nyeem ntawv / thib ob, thiab tuaj yeem xa cov ntawv nyeem ncaj qha mus rau PC ntawm tib qhov ceev, thiab qhov chaw cia tsis hloov pauv tuaj yeem ncav cuag. cia qhov tob ntawm 1M bytes. Nws Cov Ntaub Ntawv Log pib ua rau muaj ntau yam kev teeb tsa, uas yog qhov tseeb thiab hloov tau. Kev siv cov cuab yeej siv hluav taws xob muaj txiaj ntsig zoo tuaj yeem txhim kho qhov tseeb ntawm AC voltage ntsuas, thiab muaj AC bandwidth ntawm 3Hz-300kHz.
Siv lub multimeter, koj tuaj yeem siv cov ntaub ntawv Log muaj nuj nqi los sau qhov tshwm sim overcharge thaum lub sijhawm siv hluav taws xob, thiab tom qab ntawd rub tawm mus rau PC nrog USB, thiab tom qab ntawd siv cov software tsom xam los tso saib thiab txheeb xyuas cov ntsiab lus sau, thiab thaum kawg pom. tawm qhov ua rau tsis ua haujlwm, pab cov engineers los daws cov teeb meem hauv kev tsim khoom. teeb meem siv tau. Hauv kev nrhiav tau thiab kev tshuaj xyuas ntawm cov ntaub ntawv hloov pauv sai sai ntawm cov ntaub ntawv waveform, seismic yoj cov ntaub ntawv, thiab lwm yam, multimeter tuaj yeem ua tiav kev ntsuas thiab ntsuas thiab ntsuas.
Tsis siv neeg ntsuas, tsis siv neeg ua kom tiav cov haujlwm ntsuas
Lub high-end desktop digital multimeter tuaj yeem siv tsis tau tsuas yog ua ib qho cuab yeej xwb, tab sis kuj tuaj yeem tsim ua tiav daim ntawv thov nrog lwm cov khoom siv los ua kom tiav ntau yam kev sim thiab ntsuas cov haujlwm. Tsis tas li ntawd, qhov kev ntsuas tsis siv neeg ntawm multimeter kuj tseem pab cov engineers ua kom tiav cov khoom kuaj.
Tsis siv neeg ntsuas kev ua haujlwm ntawm multimeter tsis muaj nyob rau hauv lwm yam khoom zoo sib xws. Nws qhov kev tshuaj xyuas sab hauv nthuav dav tuaj yeem txuas nrog cov matrix sib txawv hloov pauv, thiab txhua qhov module tuaj yeem teeb tsa nrog tus ID sib txawv los pab txhawb kev teeb tsa tsis siv neeg. Nws txhawb ntau hom kev tswj hwm lub khoos phis tawj software thiab tsav tsheb, thiab tuaj yeem yooj yim integrate multimeter nrog lub kaw lus; txheem RS-232 thiab GPIB interfaces thiab SCPI programming lus ua kom yooj yim ntawm kev sib koom ua ke.
Ua raws li cov txheej txheem kev laus hauv cov txheej txheem tsim khoom ua piv txwv, tus neeg siv tuaj yeem siv 12-txoj kev voltage sib txawv input input soj ntsuam module, kev pab cuam qhov kev ntsuam xyuas ntawm multimeter ua ntej, thiab tom qab ntawd sim 12 cov khoom ywj pheej raws li kev sim ntawm lub teem sijhawm. Tsis siv neeg sau cov ntaub ntawv taw tes thiab cia li tsim cov ntaub ntawv xov xwm hluav taws xob rau cov neeg tsim khoom los xyuas thiab txheeb xyuas cov khoom zoo thiab qhov tsis xws luag kom tshem tawm cov khoom tsis tsim nyog. Qhov tseem ceeb tshaj plaws, qhov ntsuas tsis siv neeg ntsuas qhov teeb tsa nrog multimeter tsis tas yuav tsum muaj cov neeg ua haujlwm ua haujlwm, thiab tuaj yeem paub lub sijhawm ntev tsis siv neeg saib xyuas thiab khaws cov ntaub ntawv ntawm cov khoom ntsuas.
Digital Multimeter Detect Car Faults
Thaum teeb meem cov khoom siv hluav taws xob ntawm lub tsheb, qhov tseem ceeb tshaj plaws yog cov txheej txheem kev xav ntawm qhov ua rau tsis ua haujlwm. Cov txheej txheem no tseem ceeb heev. Qhov no yog vim tias koj tsis tuaj yeem pom dab tsi sab hauv thiab nws tsis yooj yim sua kom disassemble ntau cov khoom xws li cov khoom siv tshuab. Cov teeb meem tuaj yeem pom sai sai los ntawm kev siv logic thiab cov kauj ruam tsim nyog. Thiab cov cuab yeej tseem ceeb hauv cov txheej txheem no yog multimeter.
Multimeter yog ib qho ntawm cov khoom siv hluav taws xob kho tsheb feem ntau siv los ntsuas qhov hluav taws xob, tam sim no thiab tsis kam. Txawm li cas los xij, qhov input impedance ntawm analog (pointer) multimeter siv nyob rau hauv thaum ntxov theem yog tsawg heev, uas muaj kev cuam tshuam zoo rau cov hluav taws xob Circuit Court thaum ntsuas. Hom 'meter' no feem ntau siv 9V voltage thaum kuaj tsis kam, yog li nws yooj yim rau kev puas tsuaj rau cov khoom siv hluav taws xob rhiab heev. Tab sis RIGOL digital multimeter multimeter zam dhau qhov xwm txheej no.
Nws cov input impedance yog siab, thiab nws qhov tseeb thiab kev nyab xeeb yog superior rau analog watches. Qhov hluav taws xob thaum ntsuas qhov ntsuas kuj tseem qis, yog li nws yuav tsis ua rau cov khoom ntawm txhua qhov kev nkag siab. Tab sis kuj tseem muaj teeb meem nrog lub rooj digital dav dav. Nws tsis tuaj yeem tso saib cov ntaub ntawv hloov pauv ntawm qhov nce lossis txo qhov ntsuas kev nyeem ntawv. Nyob rau hauv qhov kev xeem emission emission test thiab engine tsom xam, nws yuav pom tias cov ntshiab digital meter tsis tuaj yeem muab tus nqi hloov pauv ruaj khov. Lub multimeter kov yeej qhov tsis txaus ntawm cov ntsuas digital thiab hloov nws nrog analog / digital ua ke ntsuas. Nws tsis tsuas yog muaj qhov zoo ntawm cov ntsuas ntsuas digital, tab sis kuj muaj qhov zoo ntawm kev ntsuas dynamic ntawm analog watches.
Kev soj ntsuam ntawm lub hauv paus chaw nres tsheb hluav taws xob teeb liab
Raws li cov khoom siv loj, lub hauv paus chaw nres tsheb yuav tsum tau saib xyuas ntau lub teeb liab. Tshwj xeeb tshaj yog kev saib xyuas cov khoom siv hluav taws xob thiab ib puag ncig ntawm lub hauv paus chaw nres tsheb. Cov khoom siv hluav taws xob yog qhov tsim nyog rau kev ua haujlwm ntawm cov khoom siv. Qhov sib txawv ntawm ib puag ncig yam xws li kub thiab av noo yuav cuam tshuam rau kev ua haujlwm thiab lub neej ntawm cov khoom siv. Kev saib xyuas qhov ntsuas qhov tseem ceeb hauv cov ntsiab lus no pab tiv thaiv thiab daws teeb meem. Kev saib xyuas mus sij hawm ntev thiab kev txheeb cais thiab kev txheeb xyuas cov ntaub ntawv khaws tseg tuaj yeem muab cov ntaub ntawv siv ntau ntxiv rau kev siv yav tom ntej thiab kev txhim kho tom ntej.
Nyob rau hauv tag nrho lub hauv paus chaw nres tsheb system, lub hwj chim mov module muab lub hwj chim rau txhua module. Ntawm lawv, muaj plaub yam khoom siv hluav taws xob rau lub rooj tsavxwm hauv RF module, uas yog 7.2V, 5.5V, 3.3V thiab 2.5V, thiab qhov yuav tsum tau muaj qhov tseeb yog ntxiv rau 1 feem pua. Lub ambient kub ntawm lub computer chav tsev ntawm lub hauv paus chaw nres tsheb yog ib txwm nyob nruab nrab ntawm 15 thiab 30 degree, txwv tsis pub nws yog txawv txav, thiab cov av noo ntawm lub computer chav tsev yog li ntawm 40 feem pua thiab 65 feem pua, txwv tsis pub nws yog txawv txav. Cov ntaub ntawv niaj hnub no tuaj yeem saib xyuas los ntawm kev tshuaj xyuas kev ua haujlwm ntawm high-end digital multimeter.
