Yuav siv thiab ceev faj li cas nrog cov ntaub ntawv Multimeter Resistance
Kev Ntsuas Kev Tiv Thaiv Kev Tiv Thaiv
(1) Yog tias qhov ntsuas ntsuas tus nqi siab tshaj qhov siab tshaj plaws ntawm qhov kev xaiv ntau, cov zaub yuav qhia ntau tshaj "1", koj yuav tsum xaiv ntau dua, rau cov resistors ntau dua 1 MΩ lossis siab dua, nws yuav siv sijhawm li ob peb feeb. rau kev nyeem ntawv kom ruaj khov, nws yog ib txwm muaj rau kev nyeem ntawv siab.
(2) Thaum tsis muaj cov tswv yim, xws li qhib Circuit Court, cov zaub yog "1".
(3) Thaum kuaj xyuas cov kab hauv impedance, xyuas kom meej tias tag nrho cov khoom siv hluav taws xob ntawm cov kab ntsuas raug txiav thiab tag nrho cov capacitors raug tso tawm.
(4) Muaj txog plaub lo lus rau 200MΩ luv Circuit Court, uas yuav tsum tau muab rho tawm los ntawm kev nyeem ntawv thaum ntsuas, xws li thaum ntsuas l00MΩ kuj, cov zaub yog 101.0, plaub lo lus yuav tsum tau muab rho tawm.
(5) muaj cov ntaub ntawv tiv thaiv tsis zoo ntawm lub peev xwm yog qhov zoo lossis qhov tsis zoo, nrog tus cwj mem liab txuas nrog lub davhlau ya nyob twg zoo ntawm lub capacitor, tus cwj mem dub txuas nrog lub davhlau ya nyob twg tsis zoo ntawm lub capacitor, multimeter siv fais fab mov yuav yog los ntawm kev siv resistor ntawm lub capacitor them, thaum ib txwm, lub multimeter qhia tau hais tias lub charger voltage yuav yog tus nqi qis los ntawm ib tug gradual nce mus txog rau thaum cov zaub overflow. Yog hais tias lub charger pib qhia overflow "1", lub capacitor yog qhib Circuit Court; yog tias nws ib txwm pom tias yog qhov ruaj khov los yog "000", nws txhais tau hais tias lub capacitor tau tawg lossis luv luv.
(6) xyuas lub Circuit Court rau thiab tawm, qhov hloov ua haujlwm yuav tsum tau hu rau "" cov ntaub ntawv, thiab tsis txhob siv cov ntaub ntawv tiv thaiv. Kev ntsuas ntev npaum li koj tsis hnov ib lub suab nrov, koj tuaj yeem txiav txim rau lub voj voog tsis txuas.
(7) Thaum ntsuas qhov kev tiv thaiv me me, koj yuav tsum ua ntej luv luv ntawm ob lub cwj mem thiab nyeem nws tus kheej ntawm kev sib txuas ntawm tus cwj mem (feem ntau 0. 2 ~ 0. 3 ohms) txhawm rau kho qhov ntsuas tsis kam.
(8) Cov ntaub ntawv tiv thaiv muaj kev tiv thaiv tshaj qhov hluav taws xob muaj nuj nqi, qhov ntsuas tsis zoo tam sim ntawm qhov hluav taws xob hauv qhov kev teev tseg yuav tsis ua rau muaj kev puas tsuaj. Piv txwv li, DT-830 digital multimeter kuj cov ntaub ntawv siab tshaj plaws tso cai tawm qhov hluav taws xob (DC lossis AC ncov) ntawm 250 volts, uas yog cov ntaub ntawv tiv thaiv kev siv tsis raug ntawm qhov ntsuas ntsuas qhov ntsuas kev ruaj ntseg, tab sis tsis muaj hluav taws xob (xws li roj teeb, tib neeg lub cev, thiab lwm yam) ntsuas kev tiv thaiv, uas yuav ua rau lub multimeter tsis kam raug poob, los yog kev puas tsuaj.
