Yuav ua li cas siv ib tug multimeter los ntsuas luv luv Circuit Court breakers, to
Yuav ua li cas txheeb xyuas cov luv luv thiab luv luv Circuit Court
Paub meej tias lub Circuit Court yuav tsum nyob rau hauv ib tug de-energised lub xeev ua ntej nrhiav tau, thiab nws yog nruj me ntsis txwv tsis pub ua hauj lwm nrog hluav taws xob, tshwj xeeb tshaj yog high voltage. Yog tias koj siv lub pointer multimeter, koj tsuas yog yuav tsum tau ntaus nws mus rau R × 10 iav, digital multimeter yuav muaj lub buzzer tso, koj tuaj yeem siv ncaj qha buzzer iav, lossis tseem siv cov iav tiv thaiv.
Them mloog mus rau tus cwj mem ntxig txoj kev, tus cwj mem dub tso rau hauv COM jack, tus cwj mem liab tso rau hauv qhov ntsuas qhov ntsuas hluav taws xob. Tus cwj mem multimeter ntawm ob qhov kawg yuav tsum ntsuas, tus pointer multimeter cwj mem tsis txav, sawv cev ntawm tus nqi tsis kam ntawm infinity, uas yog, lub xeev Circuit Court breaking. Digital multimeter disconnected xeev rau cov ntaub ntawv buzzer tsis suab, los yog nrog cov ntaub ntawv tiv thaiv cov zaub yog 1.
Yog hais tias tus pointer multimeter koob tag nrho bias, digital multimeter poob suab, los yog tus nqi kuj qhia tias xoom los yog tsawg heev, nws qhia tau hais tias nyob rau hauv luv luv-circuit xeev.
Leakage yog qhov xau ntawm tam sim no vim kev puas tsuaj los yog lwm yam laj thawj. Cov cuab yeej siv lub plhaub thiab cov khoom siv hluav taws xob vim qee qhov laj thawj txuas rau hauv av thiab hauv av ntawm qee qhov sib txawv yuav ua rau muaj dej ntws.
Cov khoom siv hluav taws xob them nqi ntsuas: digital multimeter lossis pointer multimeter ntsuas, ua si rau 250V AC voltage iav, xyuam xim rau qhov chaw ntawm cov cwj mem liab thiab dub kom paub qhov txawv. Kev ntsuas qhov xav tias yuav xau ntawm cov khoom siv hluav taws xob hlau plhaub, tus cwj mem txuas nrog lub plhaub ntawm cov khoom siv, lwm tus cwj mem hauv av (lossis kais).
Pointer lossis digital zaub voltage siab dua ntawm 30-50V, hloov mus rau AC 50V iav, yog tias lub zog hluav taws xob tau lees paub tias siab dua 30 volts ntawm cov xau, qis dua 30 volts yog qhov qub, thiab tom qab ntawd xoom, hluav taws xob fais fab mov plug kab mus rau txoj cai ntsuas ib zaug tuaj yeem txiav txim siab.
Koj tuaj yeem siv lub ntsuas hluav taws xob ntsuas hluav taws xob, txoj hauv kev zoo tshaj plaws los txheeb xyuas qhov xau yog siv lub cwj mem hluav taws xob tiv tauj lub cev, yog tias lub teeb neon npuas tam sim ntawd tawm mus, ua pov thawj tias lub cev them hluav taws xob yog hluav taws xob zoo li qub, yog tias lub teeb ci ntev. leakage undoubtedly.
