Kev Siv Hluav Taws Xob thiab Kev Ntsuas rau Multimeters
1. Kev xaim yuav tsum raug
Lub qhov (sockets) los yog terminals ntawm lub vaj huam sib luag multimeter muaj cov cim polarity. Thaum siv rau kev ntsuas DC, nws yuav tsum tau them sai sai rau tsis txhob thim rov qab qhov zoo thiab qhov tsis zoo; Thaum ntsuas qhov tsis kam ntawm diode nrog multimeter, uas yog, thaum qhov txawv ntawm polarity ntawm diode, nws yuav tsum tau muab sau tseg tias lub qhov (socket) "ntxiv" txuas nrog rau qhov tsis zoo electrode ntawm lub roj teeb sab hauv.
Thaum ntsuas tam sim no, lub multimeter yuav tsum tau txuas nrog hauv series nrog lub voj voog; Thaum ntsuas qhov hluav taws xob, lub multimeter yuav tsum tau txuas nrog tib lub voj voog.
2. Ntsuas lub iav kom raug
Cov iav ntsuas suav nrog ob yam: xaiv cov khoom ntsuas thiab xaiv 20 feem pua. Ua ntej kev ntsuas, cov iav sib thooj yuav tsum raug xaiv raws li kev kwv yees ntxhib ntawm cov khoom ntsuas thiab nws qhov loj me.
Vim muaj ntau yam khoom ntsuas thiab ntau yam ntawm lub tshuab multimeter, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau kev hloov kho iav thaum siv, txwv tsis pub lub ntsuas yuav raug puas tsuaj loj. Piv txwv li, thaum ntsuas qhov ntsuas hluav taws xob, yog tias lub ntsuas ntsuas tau muab tso rau hauv ohm lossis tam sim no, thiab thaum ntsuas qhov ntsuas hluav taws xob siab thiab siab tam sim no, siv qhov ntsuas qis qis yuav ua rau muaj kev puas tsuaj rau lub ntsuas.
3. Kev ntsuas kev tiv thaiv yuav tsum tsis txhob ua haujlwm nrog hluav taws xob
Thaum ntsuas kev tiv thaiv, nws tsis raug tso cai los ua nws raws li qhov kev them nqi, txwv tsis pub nws tsis tsuas yog cuam tshuam qhov tseeb ntawm qhov ntsuas, tab sis kuj tseem tuaj yeem hlawv cov ntsuas.
4. Tsis txhob hloov ntau yam nrog lub zog
Kev hloov pauv ntawm qhov tam sim no thiab qhov hluav taws xob yuav tsum tsis txhob ua nyob rau hauv cov xwm txheej nyob, tshwj xeeb tshaj yog thaum muaj hluav taws xob siab thiab tam sim no, kom tsis txhob hlawv tawm qhov hloov pauv hloov.
