Seb multimeter rau koj voltage txoj kev ntsuas cov

Multimeter los ntsuas voltage-tu plaub

(1) lub multimeter ua ntej yuav siv, yuav tsum tau ua txhua yam xoom;

(2) tus multimeter yuav tsum mus kawm qib, los txo cawv ntawm lwm magnetic teb rau nws;

(3) assumes tias lub hom phiaj li voltage yog tsis paub, koj yuav tsum tau muab tus tes hloov qhov muaj nuj nqi ntau qhov rooj thiab maj declined;

(4) yog in the process of xab ntau yam tsis yog raws li, koj yuav tsum tau disconnect rau ntau yam tom qab rooj hloov tsis tau yuav ntsuas in the process of shifting;

(5) assumes tias cov ' meter ' flashes flashes xwb "1", ntawm qhov ntau yog tsawg heev, tus tes hloov qhov kev ua yuav tsum tau muab tso rau lub teev loj;

(6) kev kuaj ntshav voltage, yuav tau attentive tshwj xeeb kom tsis txhob poob siab electric;

(7) tus multimeter nyob rau hauv daim ntawv thov txheej txheem, yuav tsis tau kov cov tes sheet hlau kom ruaj ntseg rau tus kheej thiab cov cav laij tau qhov;

(8) lub multimeter siv tom qab tus tes hloov qhov kev ua yuav tsum muab los sib tham ntau lawm feem ntau cov voltage, yog lub caij nyoog ntev los tsis thov, koj yuav tsum tshem cov roj teeb nrog tiv thaiv corrosion daim ntawv thiab lwm yam khoom siv.
