Qhov sib txawv ntawm qhov ntsuas qhov tseeb ntawm me me kuj ntawm multimeter
Tam sim no multimeters hauv txhua qhov chaw ntawm lub neej tau dhau los ua cov cuab yeej yooj yim rau txhua tus. Raws li qhov sib txawv ntawm kev siv, tes tuav multimeters muab faib ua peb thiab ib nrab tus lej, plaub thiab ib nrab tus lej, tsib thiab ib nrab tus lej thiab lwm yam qauv. Multimeters muaj zog thiab tuaj yeem siv los ntsuas qhov hluav taws xob, tam sim no, tsis kam, thiab lwm yam. Tam sim no, txhawm rau pab txhawb txhua tus neeg siv, high-end multimeters kuj tau nruab nrog cov haujlwm xws li diode, capacitance, tsis kam, thiab kev ntsuas hluav taws xob tiv thaiv.
Thaum koom nrog hauv automotive electronics, hluav taws xob hluav taws xob, thiab lwm yam thiab yuav tsum tau sim cov yam ntxwv ntawm kev ua haujlwm me me, qee cov tuam txhab yuav siv cov khoom siv hluav taws xob zoo tib yam los ntsuas, tab sis los ntawm cov kws tshaj lij pom zoo, peb pom zoo tias qhov kev tawm tsam hauv qab 3. 0Ω yuav tsum tsis txhob raug kuaj los ntawm ob txoj hlua hlau. , Peb lub tuam txhab sib piv cov qauv peb-thiab-ib-ib-ib-nrab-tus lej, plaub-thiab-ib-ib-nrab-tus lej, tsib-thiab-ib-nrab-tus lej multimeters thiab micro-ohmmeters nrog plaub-xaim txoj kev sib piv. Piv txwv tias qhov tsis kam ntawm 1Ω raug kuaj, qhov tseeb yog qhia raws li 0.1 feem pua ntawm kev nyeem ntawv ntxiv rau 5 tus lej kawg (qhov sib txawv ntawm cov khoom sib txawv), qhov sib piv yog raws li hauv qab no:
Los ntawm cov lus sib piv, peb tuaj yeem pom tias thaum qhov kev tawm tsam yog 1Ω, qhov tsis paub tseeb ntawm qhov kev ntsuas siab ntawm tsib-thiab-ib-ib-ib-nrab multimeter tuaj yeem ncav cuag 5 feem pua, thaum qhov tseeb ntawm multimeter siv plaub-xaim txoj kev. tuaj yeem ncav cuag 0.35 feem pua, yog li thaum txiav txim siab qhov kev sim Thaum qhov kev tiv thaiv me me, lub micro-ohmmeter rau plaub-hlau txoj kev sim yog qhov tseem ceeb.
Xav txog qhov ua tau zoo thiab yooj yim ntawm multimeter, Lub teb chaws Yelemees GMC-I tau ntxiv cov haujlwm micro-ohmmeter rau plaub thiab ib nrab tus lej multimeter, uas tuaj yeem ua tau raws li kev siv yooj yim ntawm kev ua haujlwm xws li tsheb hluav taws xob thiab cov khoom siv hluav taws xob.
4½-tus lej tseeb RMS digital multimeter METRAHIT AM series
True RMS 12, 000 Cov lej tso saib
Txiav-ntug technology permeates txhua yam. METRAHIT AM series high-end multimeters yog qhov ruaj khov thiab ua kom ntseeg tau cov yam ntxwv ua tau zoo hauv txhua yam. Lawv tau nruab nrog cov thev naus laus zis thev naus laus zis uas ua kom cov txiaj ntsig tau zoo. Nws ergonomic tsim muab qhov siab tshaj plaws ntawm kev siv yooj yim thiab kev nyab xeeb. Nrog nws cov haib thiab ntau yam nta, nws yog qhov zoo tagnrho rau kev thov kev ntsuas kev ua haujlwm hauv ntau yam kev siv.
