Combination multi-gas detector siv thiab tu cov lus qhia
1, ua ntej siv, koj yuav tsum ua tib zoo nyeem phau ntawv ntawm Santron A830L multimeter, paub txog lub luag haujlwm ntawm lub hwj chim hloov, hloov ntau yam, jacks, tshwj xeeb sockets .... Txhawm rau kom tus thawj pib kawm yooj yim, Kuv nyob hauv Daim duab kawg tshwj xeeb tshaj yog cim nws txoj haujlwm tag nrho.
2, Thaum siv cov digital multimeter, ua ntej tso lub hwj chim hloov hauv ON txoj haujlwm.
3, kev ntsuas ntawm AC thiab DC voltage ntsuas: raws li qhov yuav tsum tau hloov pauv mus rau DCV ( sawv cev ntawm DC voltage) lossis ACV ( sawv cev ntawm AC voltage) ntawm qhov tsim nyog, tus cwj mem liab tso rau hauv V / Ω qhov, tus cwj mem dub tso rau hauv COM qhov, thiab tus cwj mem thiab kab yuav tsum ntsuas nyob rau hauv tib lub sijhawm, kev nyeem ntawv tau tso tawm rau qhov tseeb ntawm qhov ntsuas ntawm lub sijhawm no.
4, Kev ntsuas ntawm AC thiab DC tam sim no: Hu rau qhov hloov pauv mus rau qhov tsim nyog ntawm DCA (rau DC tam sim no) lossis ACA (rau AC tam sim no), ntxig tus cwj mem liab rau hauv mA qhov (＜200mA) lossis 10A qhov (＞ 200mA), ntxig tus cwj mem dub rau hauv COM lub qhov, thiab txuas lub multimeter hauv series hauv Circuit Court los ntsuas. Thaum ntsuas qhov ncaj qha ntws, cov multimeter digital tuaj yeem tso saib qhov polarity (piv txwv li, thaum ntsuas cov cwj mem liab thiab dub hauv series hauv Circuit Court hauv qab kev sim, thim rov qab rau pem hauv ntej ntawm tus nqi zaub, tsuas yog ntxiv cov cim tsis zoo "a") .
5, qhov ntsuas ntawm qhov ntsuas tus nqi ntawm cov resistor: qhov hloov pauv mus rau Ω ntawm qhov tsim nyog, tus cwj mem liab rau hauv V / Ω qhov, tus cwj mem dub rau hauv lub qhov COM. Yog hais tias tus nqi ntsuas tsis kam tshaj qhov siab tshaj plaws ntawm qhov kev xaiv, lub multimeter yuav tso saib "1", ces koj yuav tsum xaiv ntau dua. Thaum ntsuas kev tiv thaiv, tus cwj mem liab yog qhov zoo thiab tus cwj mem dub yog qhov tsis zoo, uas yog qhov txawv ntawm tus pointer multimeter. Yog li ntawd, thaum ntsuas transistors, electrolytic capacitors thiab lwm yam khoom nrog polarity, koj yuav tsum tau them sai sai rau lub polarity ntawm tus cwj mem.
Txhawm rau ntxiv cov ntawv kawg, lub tshuab hluav taws xob digital, ntau lub hom phiaj ntsuas hluav taws xob, feem ntau muaj cov haujlwm xws li ammeter, voltmeter, ohmmeter, thiab lwm yam, thiab qee zaum hu ua multimeter, multi-meter, multi-meter, los yog tri-meter.
Kev ntsuas tam sim no, voltage, thiab tsis kam yog feem ntau suav hais tias yog cov haujlwm yooj yim ntawm multimeter.
