Ukulinganisa ibhetri kubi, kodwa isetyenziselwa ukulinganisa iiparameters ezifana ne-voltage kunye nekhoyo. Idityaniswe kunye, vula ibhokisi yangaphandle, ukuba unokubona i-terminal eyahlukileyo yebhetri nganye, emva koko ususe intambo yomthwalo, ungasebenzisa intambo phakathi kwebhetri, ukusetyenziswa okulula kwesigwebo sokulinganisa i-multimeter. 1.
Ukuba kukho ibhetri ngokukhawuleza, isibonakaliso kukuba: kwimeko yamandla apheleleyo, umgama wokuqhuba uyancipha kakhulu, isithuthi sombane sibonisa ukutshaja kwakhona kwegridi yokutshaja. Ukuhlawula ngokungabikho kombane, akukho ntlawulo, iya kubonisa. 2, khupha umbane opheleleyo kwindawo yokugcina ibhetri, emva koko ukhuphe iqokobhe lokugcina ibhetri.
I-3, i-multimeter ihlengahlengiswa kwi-DC 50V gear, iipilisi ezimbini (ezibomvu +, ezimnyama -) qhagamshelana nebhetri nganye + - ipali, umgangatho ngu-voltage 12V, iqhekeza lebhetri liphantsi kunalo mbane, ebonisa ukuba le bhetri iguga, yaphukile. I-4, enye ibhetri enye izaliswe nje yi-12V, kodwa ukugcinwa kwangoku akwanelanga, kukho isixhobo sokulinganisa ibhetri esizinikezele ukufumanisa. I-5, ukuba akukho sixhobo sokulinganisa, unokukhetha umthwalo omkhulu, umzekelo, i-bulb ye-12V100W, uxhulumaniso lwe-multimeter + - ngokugqithiseleyo, uze udibanise isibane, ngoko, jonga ukufundwa, ngaphantsi kwe-10V, ebonisa ukuba ibhetri. yaphukile.
Ukuba kukho ibhetri kwipakethi yebhetri yemoto yombane, kufuneka itshintshwe ngexesha. Ipakethi yebhetri yemoto yombane iphukile, eya kubangela ukuba i-voltage elinganisiweyo kunye nekhoyo ingafikeleli kumgangatho, isithuthi sombane sinzima ukuqalisa, ngelixa kubangela ukuba ezinye iibhetri zikhawuleze umonakalo. Zama ukutshintsha ibhetri entsha, ukusebenza kwebhetri endala kuyahluka, ukusebenza kutsalwa ngokunzulu, kubangele ukusebenza okuphantsi.
Ukuba kukho nayiphi na enye ixabiso lokusetyenziswa, kufuneka ukhethe i-1, kwaye kungcono ukuyisebenzisa. Izizathu ezibalulekileyo: Ukongeza kwimveliso eqhelekileyo, kuyimfuneko ukuba ne-low-supplement voltage, okanye ibhetri engasebenziyo; ibizwa ngokuba yisekethe elinganayo kwisekethe; Isizathu sinjalo.
