Yuav ua li cas siv ib tug multimeter los kuaj xyuas luv luv hauv circuits
1) Tshem tawm lub hwj chim ua ntej, teeb tsa txoj haujlwm hloov ntawm lub tshuab multimeter mus rau txoj haujlwm buzzer, thiab tso ob qhov kev xeem coj ntawm multimeter ntawm ob lub terminals yuav tsum tau sim. Yog hais tias muaj ib tug luv luv Circuit Court, yuav muaj ib tug buzzer thiab ib tug me me conduction voltage tus nqi yuav tshwm sim. Lub sijhawm no, muaj luv luv ntawm ob lub ntsiab lus ntsuas.
2) Siv ib lub multimeter los ntsuas cov kab hluav taws xob kom paub seb cov kab puas yog luv luv. Piv txwv li, thaum ntsuas kev rwb thaiv tsev ntawm ib theem rau hauv av, yog tias tus nqi rwb thaiv tsev yog xoom (hlau grounding) lossis qis heev (tsis yog xim hlau grounding), nws tuaj yeem txiav txim siab tias cov kab no yog grounded. Yog tias tsis muaj av, cov nqi rwb thaiv tsev yog siab heev. Tom qab ntawd ntsuas cov theem-rau-theem rwb thaiv tsev. Yog tias qhov hluav taws xob theem-rau-theem yog xoom, nws txhais tau hais tias muaj qhov luv luv ntawm ob theem kab.
3) Xyuas kom tseeb tias tsis muaj hwj chim nyob rau hauv kab, siv qhov chaw tiv thaiv (lub pointer meter yog teem rau RX10, lub 'meter' muaj ib tug on-off teeb uas yuav beep ib pliag), kov ob meter rods rau lub ob lub ntsiab lus (los yog ob kab) yuav tsum ntsuas, thiab tus pointer tsis txav. Nws yog ib qho qhib Circuit Court, thiab yog tias qhov ntsuas tag nrho dhau, nws yog luv luv; lub ntsuas hluav taws xob lub ntsuas hluav taws xob qhib tsis hloov, thiab tsis muaj suab, tab sis luv luv Circuit Court yuav beep, lossis tus lej yog xoom.
4) Sib cais cov hlau cores ntawm ob qhov kawg ntawm cov hlau tsis txhob kov ib leeg, tom qab ntawd muab lub multimeter mus rau qhov chaw thiab saum toj no, thiab muab qhov kev xeem coj mus rau cov xov hlau ntawm ob xim sib txawv. Yog hais tias tus nqi ntsuas nyob rau hauv 0.5 trillion Yog hais tias tus nqi siab tshaj 0.5 ohms, los yog nws qhia infinity, ces tsis muaj teeb meem nrog lub rwb thaiv tsev ntawm kab, uas yog, muaj tsis muaj qhov xau hauv kab; yog tias qhov ntsuas tus nqi qis dua 0.5 megohms, ces cov kab rwb thaiv tsev tsis tsim nyog thiab muaj qhov to. Nrhiav tag nrho cov pob qij txha thiab cov thawv sib txuas hauv kab tom qab lub tshuab hluav taws xob hluav taws xob no kom pom tias cov rwb thaiv tsev ntawm cov pob qij txha tsis zoo, thiab tom qab ntawd kos nrog ntau lub ntsuas ntawm txhua qhov sib koom ua ke thiab cov thawv sib txuas uas siv txoj kev ntsuas kev tiv thaiv. Yog vim li cas yog tias ib tug loj tam sim no yog generated nyob rau hauv lub caij luv luv Circuit Court thiab lub Circuit Court breaker txiav tawm mus. Lub Circuit Court yuav tsis hlawv ntau. Feem ntau, txoj hauj lwm ntawm qhov luv luv tuaj yeem txiav txim siab los ntawm kev ntsuas kev tiv thaiv ntawm qhov sib koom los yog lub thawv sib txuas.
