Nrhiav luv luv Circuit Court, qhib circuits thiab xau nrog multimeter
Multimeter yog ib qho ntawm cov cuab yeej siv ntau tshaj plaws rau cov neeg siv hluav taws xob, cov neeg ua haujlwm tu, hluav taws xob engineers, hardware engineers, hauv kev tshawb nrhiav cov hluav taws xob circuits, qhov chaw txhaum yuav tsum tsawg dua. Ib tug me me multimeter, nws muaj nuj nqi yog heev haib, koj muaj peev xwm ntsuas kuj, capacitance, diode, transistor, DC voltage, AC voltage, tam sim no, thiab lwm yam. , kawm siv lub multimeter, ib qho yooj yim txhaum ua-nws-koj tus kheej.
Yuav ua li cas siv lub multimeter los nrhiav luv luv Circuit Court
Kev ntsuas luv luv hauv kev saib xyuas hluav taws xob, kev tiv thaiv qhov chaw txhaum yog ntau heev, kev ntsuas qhov luv luv ntawm qhov tsis raug, yuav tsum xyuas kom meej tias cov khoom siv hluav taws xob raug txiav, tsis txhob nco qab ua haujlwm nrog hluav taws xob. Kev ntsuas luv luv siv cov ntaub ntawv multimeter buzzer lossis ohm cov ntaub ntawv rau kev ntsuas, kev siv lub buzzer thaum qhov kev ntsuas yog ntau intuitive, thaum cov kab luv luv, lub multimeter yuav ncaj qha "beeping", lub hauv paus ntsiab lus ntawm cov ntaub ntawv buzzer Thaum qhov kev ntsuas ntawm qhov kev tiv thaiv tus nqi tsawg dua li ntawm 75 Ω, multimeter beeping, yog tias koj xav paub ntau ntxiv txog qhov kev tawm tsam ntawm ob kab, koj tuaj yeem siv cov ntaub ntawv 200 Ω. Yog tias koj xav paub tus nqi tiv thaiv ntawm ob kab ntau dua, koj tuaj yeem siv 200Ω los ntsuas. Ntsuas siv lub buzzer iav, qee zaum qhov tseeb sab hauv tsis kam ntawm ob lub teeb liab me me, nws yooj yim rau kev txiav txim siab, xws li relays / contactor coils, ntau relays / contactor coils impedance tsawg dua 75 Ω, kev siv cov buzzer iav ntsuas. yuav beeping xav luv luv-circuit, tab sis qhov tseeb tsis muaj.
Cov kws ua haujlwm feem ntau siv cov ntaub ntawv multimeter buzzer kom pom cov kab lossis cov ntsiab lus luv luv-circuit tsis ua haujlwm, xws li ntsuas kev tiv thaiv, capacitance yog luv luv, diode thim rov qab tawg, transistor tawg (transistor breakdown feem ntau luv luv-circuited puag thiab emitter), integrated circuit chip fais fab mov thiab av luv luv-circuited, ob-pin luv-circuit thiab hais txog.
