Multimeter Test rau Memory Chips
Ntxig lub xov tooj liab rau hauv "V / Ω" qhov (socket), xaiv qhov ntsuas qhov ntsuas qhov tsim nyog raws li qhov loj ntawm qhov tsis kam, thiab kov ob qhov kawg ntawm qhov kev tawm tsam nrog cov liab thiab dub sojntsuam. Saib xyuas kev nyeem ntawv. Tshwj xeeb tshaj yog thaum ntsuas qhov tsis kam ntawm lub rooj tsav xwm hauv Circuit Court, lub hwj chim ntawm lub Circuit Court yuav tsum raug muab tua ua ntej kom tsis txhob nyeem ntawv jitter. Nws yog txwv tsis pub ntsuas tam sim no lossis voltage (tshwj xeeb tshaj yog AC 220V voltage) siv hom kev tiv thaiv, txwv tsis pub nws yooj yim rau kev puas tsuaj rau multimeter. Tsis tas li ntawd, kev siv cov qib kuj tseem tuaj yeem txiav txim siab qhov zoo ntawm cov capacitors. Ua ntej, luv luv-circuit ob tug ncej ntawm lub capacitor (siv ib qho kev sojntsuam ib txhij kov ob tug ncej kom tso tawm lub capacitor), ces kov ob lub probes ntawm lub multimeter mus rau ob tug ncej ntawm lub capacitor raws li, thiab soj ntsuam cov displayed resistance reading. Yog hais tias qhov kev nyeem ntawv tsis kam tso tawm thaum pib me me (sib npaug rau luv luv Circuit Court), thiab tom qab ntawd lub capacitor pib them, qhov kev nyeem ntawv tsis zoo yuav maj mam nce, thiab tom qab *, qhov kev nyeem ntawv pom tau dhau los ua "1" (sib npaug rau qhov qhib Circuit Court), nws qhia tau tias lub capacitor zoo. Yog hais tias qhov kev nyeem ntawv kuj tseem tsis hloov pauv tom qab ua raws li cov kauj ruam saum toj no, nws qhia tau tias lub capacitor puas lawm (qhib Circuit Court lossis luv luv). Nws yog ib qho tseem ceeb tshwj xeeb uas yuav tsum nco ntsoov tias thaum ntsuas, qhov tsim nyog kuj yuav tsum tau xaiv raws li qhov loj ntawm lub capacitor, piv txwv li, 200k ntau yuav tsum tau siv rau 47 μ F, thiab 2M ntau yuav tsum tau siv rau 4.7 μ F, thiab lwm yam.
Cov kev ceev faj
Ua tib zoo xaiv qhov tseeb ntau yam thiab lub qhov (socket) liab. Thaum ntsuas qhov tsis paub qhov ntau, qhov ntau yuav tsum tau hloov ua ntej rau * loj, thiab tom qab ntawd hloov los ntawm loj mus rau me me kom txog thaum tsim nyog. Yog tias "1" tshwm sim, nws qhia tias overcutting thiab qhov ntau yuav tsum tau nce.
Thaum tsis ntsuas, lub hwj chim yuav tsum muab tua tam sim ntawd.
Thaum hloov qhov ntau, qhov kev sojntsuam yuav tsum raug txiav tawm ntawm qhov ntsuas ntsuas.
Thaum ntsuas tam sim no, tsis txhob overloading.
Nws tsis raug tso cai los ntsuas qhov ntsuas hluav taws xob siv qhov kev tiv thaiv thiab qhov chaw tam sim no
