Auna juriya (Mai nuna Haɗin kai)
(1) Zai fi sauƙi idan akwai jagorar firikwensin. Da farko yi amfani da multimeter don auna juriya na shigarwa da fitarwa na firikwensin, sannan kwatanta shi da jagorar. Idan akwai babban bambanci, za a karye.
(2) Idan babu jagora, to, auna juriya na shigarwa, wanda shine juriya tsakanin EXC+ da EXC-; juriya na fitarwa, wanda shine juriya tsakanin SIG + da SIG-; juriya ga gada, wanda shine EXC + zuwa SIG +, EXC + zuwa SIG-, Juriya tsakanin EXC- zuwa SIG +, EXC- zuwa SIG-. Juriya na shigarwa, juriya na fitarwa, da juriyar gada yakamata su gamsar da alaƙa mai zuwa:

"2", juriyar gada daidai take ko daidai da juna.
Aunawa ƙarfin lantarki (mai nuna alama yana da kuzari)
Da farko, yi amfani da multimeter don auna ƙarfin lantarki tsakanin EXC+ da EXC- tasha na mai nuna alama. Wannan ita ce ƙarfin motsa jiki na firikwensin. Akwai DC5V da DC10V. Anan mun dauki DC5V a matsayin misali.
Fitar da firikwensin firikwensin da muka taɓa shine gabaɗaya 2 mv/V, wato, siginar fitarwa na firikwensin ya yi daidai da alaƙar madaidaiciyar 2 mv ga kowane irin ƙarfin kuzari na 1V.
Lokacin da babu kaya, yi amfani da multimeter don auna lambar mv tsakanin layin SIG+ da SIG. Idan kusan 1-2mv ne, yana nufin cewa daidai ne; idan lambar mv ta fi girma, yana nufin cewa firikwensin ya lalace.
Lokacin lodawa, yi amfani da fayil mv multimeter don auna lambar mv tsakanin SIG+ da SIG- wayoyi. Zai haɓaka gwargwadon nauyin da aka ɗora, kuma matsakaicin shine 5V (voltage mai ban sha'awa) * 2 mv / V (hankali) = game da 10mv, idan ba , Yana nufin cewa firikwensin ya lalace.
