Momwe mungayesere mabatire a gofu ndi multimeter (chitsogozo)

Zamkatimu

Tsegulani mayeso ozungulira

Limodzi mwamavuto omwe amafala kwambiri pamagalimoto a gofu ndi kukhetsa kwa batire ya ngolo ya gofu. Mu bukhuli, tikuphunzitsani momwe mungayang'anire komanso ngati ikufunika kusinthidwa.

Tsegulani mayeso ozungulira

Khwerero #1: Ikani chitetezo patsogolo kuti mupewe zochitika zosafunikira

Chitetezo choyamba ndi chinthu chomwe anthu ambiri amaphunzitsidwa kuyambira ali ana. N'chimodzimodzinso ndi kuyang'ana mabatire a ngolo ya gofu ndi multimeter. Pali njira zingapo zodzitetezera zomwe muyenera kuzitsatira musanayambe. Izi zikuphatikizapo:

Onetsetsani kuti multimeter yayikidwa kuti iwerenge DC voltage.
Osakhudza ma probes molunjika ku ma terminals a batri, chifukwa izi zitha kuyambitsa moto ndipo zitha kuvulaza.
Nthawi zonse muzivala magalasi otetezera chitetezo ndi magolovesi
Onetsetsani kuti galimotoyo yazimitsidwa, mabuleki oimikapo magalimoto ali oyatsidwa, ndipo makiyi achotsedwa pakuyatsa.

Khwerero #2: Yang'anani membala wamagetsi kuti muyese.

Chotsatira ndikuwunika mwakuthupi selo lamphamvu lomwe likuyesedwa ndi multimeter. Kuyang'ana kwa batri kuyenera kukhala ndi cheke cha ming'alu kapena mabowo, kuwonongeka kwa ma terminals, ndi zolakwika zina zomwe zingawoneke kunja kwa batire.

Ngati pali ming'alu kapena ming'alu pazitsulo zakunja, izi zikhoza kukhala chizindikiro cha kuwonongeka kwa mkati ndikubweretsa vuto lalikulu kwambiri pambuyo pake.

Khwerero #3 - Konzani batire kuti muyesedwe

Ngati muli ndi batri yomwe ili yovuta kufikako kapena yosokoneza, ndi bwino kuonetsetsa kuti yachangidwa mokwanira. Batire lomwe silinaperekedwe mokwanira lidzapereka mawerengedwe abodza ndikupereka chithunzithunzi kuti batire ndi yotsika pomwe siili.

Ngati mukuganiza kuti batire silikufunika kulipiritsidwa, yang'anani kuchuluka kwake hydrometer, zomwe zingakuuzeni kuchuluka kwa mphamvu zake zomwe zilipo.

Ngati hydrometer ikusonyeza kuti zosakwana 50% ya mphamvu zonse zatsala, muyenera kulipiritsa musanayambe kuyesa.

Khwerero # 4. Kuwerenga kolondola kungapezeke mwa kukhazikitsa bwino chipangizocho.

Kuti muwerenge kuchuluka kwa batire molondola, choyamba muyenera kukhazikitsa ma multimeter anu kuti muyeze voteji ya DC. Izi zikhoza kuchitika mwa kusankha malo oyenera pa nkhope ya wotchi ya chipangizocho. Mukayika, gwirizanitsani mawaya ku ma terminals a batri. Kuwongolera kwabwino kuyenera kulumikizidwa ndi kutsogolera kwabwino komanso mosemphanitsa.

Kenako yang'anani pawindo lowonetsera la multimeter kuti muwone zomwe zikuwerengedwa. Mtengo wa 12.6V kapena kupitilira apo ukuwonetsa batire yodzaza kwathunthu, pomwe mtengo wa 12.4V kapena kutsika ukuwonetsa batire yakufa.

Ngati mtengo wotsika kuposa wanthawi zonse umadziwika, yesani kulipiritsa batire kwa maola 24 ndikuyesanso ndi multimeter kuti muwone ngati izi zikubwezeretsanso magetsi.

Khwerero #5 - Lumikizani zoyeserera ku batri

Panthawiyi, mudzaonetsetsa kuti ma probe awiri a chipangizo chanu alumikizidwa bwino ndi batri. Muyenera kulumikiza mayeso ofiira kupita kumalo abwino ndipo kuyesa kwakuda kumatsogolera ku terminal yoyipa. Malo abwino amasonyezedwa ndi chizindikiro cha "+", ndipo chopanda pake chimasonyezedwa ndi chizindikiro "-" kapena "-". Mukhozanso kuwazindikira ndi mtundu wawo; chofiira chimasonyeza zotsatira zabwino ndipo zakuda zimasonyeza zotsatira zoipa.

Muyenera kugwiritsa ntchito timagulu ta alligator kuti mulumikize chipangizo chanu ku malo ofikira batire. Ngati mulibe tatifupi ta alligator, mutha kugwiritsa ntchito ma jumper ang'onoang'ono kuti mulumikize chipangizocho ndi mabatire. Komabe, tikulimbikitsidwa kugwiritsa ntchito tatifupi ta ng'ona kulumikiza chipangizo chanu ku ma terminals a batri chifukwa ndichosavuta komanso sichimalakwitsa. (1)

Khwerero #6 - Kuti muyese batri, ikani pansi pa katundu wopepuka

Kuti muwerenge ma multimeter, muyenera kuyika katundu pa batri. Izi zitha kuchitika mwa kungoyatsa nyali zakutsogolo za ngolo ya gofu. Ndi chida chokhazikitsidwa kuti chikhale voteji nthawi zonse ndi waya woyipa wolumikizidwa, gwirani waya wabwino ndi dzanja lanu lina. Mphamvu yamagetsi iyenera kukhala pakati pa 6-8 volts. Kupanda kutero, batire lingafunike kuwonjezeredwa kapena kusinthidwa. (2)

Ngati mabatire anu alumikizidwa motsatizana (zabwino za batri imodzi zimalumikizidwa mwachindunji ndi zina), muyenera kuchita izi pa batri iliyonse. Ngati alumikizidwa mofanana (zophatikiza zonse pamodzi ndi minuses zonse palimodzi), mutha kuyesa batri iliyonse.

Onani zina mwazolemba zathu pansipa.
