Kev ntsuas qhov tsis kam ntawm digital multimeter
Ntxig lub xov tooj liab rau hauv "V / Ω" lub qhov (socket) thiab xaiv qhov ntsuas qhov ntsuas qhov tsim nyog raws li qhov loj ntawm qhov tsis kam. Kev sojntsuam liab thiab dub yuav tsum hu rau ob qhov kawg ntawm kev tiv thaiv thiab saib xyuas kev nyeem ntawv. Tshwj xeeb tshaj yog, thaum ntsuas nyob rau hauv Circuit Court kuj (kuj nyob rau hauv Circuit Court board), lub hwj chim mov ntawm lub Circuit Court yuav tsum tau muab tua ua ntej kom tsis txhob ua rau kev nyeem ntawv jitter. Nws yog txwv tsis pub ntsuas tam sim no lossis qhov hluav taws xob (tshwj xeeb tshaj yog AC 220V voltage) siv qhov kev tiv thaiv ntau yam, txwv tsis pub nws yuav ua rau lub multimeter puas. Tsis tas li ntawd, kev siv cov kev sib txawv kuj tuaj yeem txiav txim siab qhov zoo ntawm lub capacitor. Ua ntej, luv luv Circuit Court ob lub terminals ntawm lub capacitor (siv ib qho kev sojntsuam ib txhij hu rau ob lub terminals kom tso tawm lub capacitor), ces kov ob lub probes ntawm lub multimeter cais mus rau ob lub terminals ntawm lub capacitor thiab saib xyuas cov kev nyeem ntawv nyeem. 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 ntawd qhov kev nyeem ntawv pom tau dhau los ua "1" (sib npaug rau qhov qhib Circuit Court. ), nws qhia tau hais tias lub capacitor zoo. Yog tias qhov kev nyeem ntawv pom tau zoo tsis hloov pauv tom qab ua raws li cov kauj ruam saum toj no, nws qhia tias lub capacitor puas lawm (qhib lossis luv). Kev saib xyuas tshwj xeeb yuav tsum tau them rau kev xaiv qhov tsim nyog qhov kev tiv thaiv raws li qhov loj ntawm lub peev xwm thaum ntsuas, xws li siv 200k ntau rau 47 μ F thiab 2M ntau rau 4.7 μ F, thiab lwm yam.
