Ndeipi chaiyo multimeter kuseta yekuyedza bhatiri remota?
Zviri mukati
Nzira chaiyo yekuyedza bhatiri ndeye multimeter. Aya madhijitari haadhure uye ari nyore kushandisa uye anowanikwa muzvitoro zvakawanda zvezvigadziriso zvemotokari. Iyo multimeter inogona kukuudza nezve mamiriro ebhatiri rekuchaja (SOC) uye kuti yakanaka here kana kuti yakagadzirira kutsiviwa. Kiyi ndeyekunzwisisa akasiyana multimeter marongero uye zvavanoreva pakuyedzwa kwebhatiri.
Heino gwara rinokurumidza kune akasiyana multimeter marongero uye maitiro avanoita:
Kutsvaga mota bhatiri multimeter kuseta? Usatarisa zvimwe! Iyo voltage renji yebhatiri yemotokari iri pakati pe15 ne20 volts. Unogona kuyedza bhatiri rako nekuisa yako multimeter kune 20V DC renji.
Chenjera
Pano iwe uchasangana neine njodzi ikozvino, saka chenjera. Tanga wadzima mota uye ona kuti makiyi abuda pakubatidza. Wobva wabvisa tambo isina kunaka kubva mubhatiri nechipanera kana socket. Apa ndipo paunobatanidza iyo dema lead kubva kune yako multimeter.
Batanidza bvunzo dzvuku inotungamira kune yakanaka terminal yebhatiri yemotokari uchishandisa imwe wrench kana socket. Yako multimeter inofanirwa kuve yakabatana kune ese mapini.
Gadzirisa yako multimeter kune chaiyo chiyero
Ita shuwa kuti multimeter yako yakaiswa kune chaiyo voltage scale. Gadzirisa ku20V, chiyero chinogona kuverenga zviri nyore ese mabhatiri e12V uye 6V. Kana iwe uine analog multimeter, ita shuwa kuti tsono yaiswa zero usati watora kuverenga - nenzira iyoyo, chero kukanganisa pane yako multimeter ichaonekwa seyakagadziriswa, kwete yekubvisa pamwe nekuverenga nhema.
Tarisa bhatiri ine mutoro wakaderera
Nhanho inotevera ndeyekusunungura zvese zvishandiso mumotokari yako uye tarisa bhatiri voltage pasi pemutoro wakaderera. Kuti uite izvi, iwe unofanirwa kuwana iyo yakanaka uye yakaipa terminals pabhatiri. Wobatanidza waya tsvuku kune yakanaka terminal uye dema waya kune iyo isina kunaka terminal.
Kana ukaona 12 volts kana kudarika pachiratidziro chako, izvi zvinoreva kuti mota yako yekuchaja system iri kushanda nemazvo uye hapana dambudziko nebhatiri. Kana ikaverenga chero chinhu pazasi 12 volts, dambudziko nderekuchaja system kana nebhatiri pacharo. Semuenzaniso, kuverenga kwe11 volts kunoreva bhatiri remota yako ine 50% kuchaji yasara, nepo 10 volts inoreva 20% chete yasara.
Tarisa bhatiri rine mutoro wakakwirira
Paunenge uchiyedza bhatiri pasi pemutoro unorema, chinja iyo multimeter kune makumi maviri volt DC renji. Kana iwe usina high load tester, shandisa 20 watt girobhu panzvimbo. Rambi re100W rinokwevera anenge 100 amps kubva mubhatiri kana riri uye nezve 8 amp kana radzimwa.
Nzira yakanakisa yekuyedza bhatiri negirobhu ndeyekubvisa kubva pamwenje wemota yako kana socket yemwenje yedome. Kana moto wadzimwa, batanidza kumucheto kwegirobhu pasi wobata rimwe divi regirobhu neprobe yemamita (Mufananidzo 2).
Ita kuti mubatsiri abatidze moto paunenge wakatarisa mita. Kana pasina kudonha kwemagetsi, ipapo bhatiri uye alternator zvakanaka. Kana iyo voltage inodonha inopfuura 0.5 volts, iwe une yakaipa kubatana kune imwe nzvimbo mune chero system.
DC vs. AC
Izvi zvimwe ndizvo zvaunonyanya kujaira. Muchiitiko ichi, ikozvino yakananga ikozvino, uye kushandura ikozvino kuchinja ikozvino. Paunenge uchiyedza mabhatiri emota, iwe unogara uchishandisa DC voltage, saka ita shuwa kuti yakarongedzwa nemazvo!
Resistance (Ohm)
Iyi parameter inokuudza kuti kupikisa kwakadini kuri mudunhu. Ohms ndiyo yakajairika unit yekuyera kuramba, saka iyi parameter inowanzonzi "Ohm". Iyi parameter inogona kukubatsira kuyera kuramba mumawaya nezvimwe zvinhu.
Voltage (V)
Iyi gadziriro inokubvumira kuyera voltage yemagetsi pakati pemapoinzi maviri mudunhu. Unogona kuedza izvi nebhatiri uye alternator kuti uone kuti iri kushanda nemazvo. Izvi zvichaiswa zvakare kunanga ikozvino (DC) kana ichiyedza mabhatiri emota sezvo ari iwo mashandiro aanoita. (1)
Zvazvino (A)
Tora multimeter uye tsvaga ikozvino kugadzika (A). Iwe unofanirwa kuona kachiratidzo kadiki kakaita senyoka inoruma muswe wayo - ichi chiratidzo chesimba razvino. (2)
Wobva watsvaga yakanaka (+) uye yakaipa (-) bhatiri terminals. Vanowanzoiswa mucherechedzo mutsvuku uye dema zvakateerana. Kana zvisina kudaro, tsvaga zvishoma "+" uye "-" zviratidzo padivi pavo.
Batanidza imwe yemultimeter inotungamira kune yakanaka terminal uye imwe kune iyo yakaipa terminal. Waya yakatsvuka yakabatana kune iyo yakanaka terminal, uye iyo nhema yakapetwa waya yakabatana kune iyo yakaipa terminal.
Zvino tarisa kuratidzwa pane yako multimeter: kana ichiratidza nhamba pakati pegumi negumi nematatu amps, bhatiri rako riri mumamiriro akanaka! Huwandu huchadzikira kana usati waikwira nguva pfupi yadarika, asi vanofanirwa kudzoka mushure mekumhanya. Ramba uchifunga kuti mabhatiri ese anobuda nekufamba kwenguva, kunyangwe ari kushanda zvakanaka izvozvi.
Tarisa zvimwe zvezvinyorwa zvedu pazasi.
