Kev ua haujlwm ntawm kev kho cov potentiometer hauv lub multimeter
Digital multimeters tuaj yeem siv los ntsuas AC thiab DC voltage, AC thiab DC tam sim no, tsis kam, capacitance thiab zaus. Cov ntsiab lus tseem ceeb ntawm nws siv yog raws li hauv qab no:
1. Test kab txoj hauj lwm: txuas cov dub xeem coj mus rau pej xeem hauv av, thiab txuas cov liab xeem coj mus rau sab jack. Ntawm lawv - 10Ib lub qhov (socket) ntsuas tam sim no, tsawg dua 400mA tam sim no lub qhov (socket test), - ntsuas qhov hluav taws xob rau qhov hluav taws xob, qhov hluav taws xob, qhov hluav taws xob thiab zaus lwm yam tsis yog tam sim no.
2. Tig qhov kev hloov pauv hloov mus rau qhov xav tau, tig lub voj voog mus rau ntawm OFF (lub xeev kaw), thiab ua qhov kev ntsuas DC voltage (DC), AC voltage (AC) kuaj, ntsuas tsis kam, ntsuas diode, kuaj tawm, Kev ntsuas ntsuas, ntsuas zaus, ntsuas triode, ntsuas tam sim no, ntsuas mA tam sim no, ntsuas tam sim no siab.
3. Kev ntsuas ntsuas thiab ntsuas ntsuas tau tso tawm rau ntawm 1-LCD zaub.
Kev kho ntawm digital multimeter yuam kev ntsuas qhov siab voltage thiab tsis pom
Hloov daim ntawv pov hwm ua ntej. Yog tias nws tsis zoo, koj yuav tsum nrhiav cov chaw tsim khoom rau kev saib xyuas tom qab muag. Yog tias qhov kev pabcuam zoo, mus rau lub vev xaib official los xyuas cov ntaub ntawv.
Nws yog kwv yees hais tias lub motherboard nti yog burnt tawm, thiab nws yog tawm ntawm warranty, yog li hloov nws nrog ib tug tshiab, thiab hu rau lub tom qab-muag kev pab cuam ua ntej.
Dab tsi yog vim li cas vim li cas cov buzzer thiab cov ntaub ntawv tiv thaiv ntawm multimeter tsis tuaj yeem raug xoom?
Yog tias nws yog tus nqi me me, nws tuaj yeem tsis quav ntsej, tus nqi tiv thaiv ntawm tus cwj mem nws tus kheej ntxiv rau tus nqi tiv tauj.
Yog tias koj xav tshem tawm cov yuam kev no, nias tus yuam sij REL nyob rau sab saum toj thaum luv luv, qhov no tuaj yeem tshem tawm qhov yuam kev, tseem hu ua kev ntsuas txheeb ze.
Kev ua haujlwm ntawm kev kho cov potentiometer hauv multimeter thiab kev saib xyuas ntawm multimeter tau qhia ntawm no! Ua tsaug rau nyeem sawv daws! Cia siab tias yuav pab tau sawv daws!
