Kodi matani olondola a multimeter kuyesa batire yagalimoto?
Zamkatimu
Njira yolondola kwambiri yoyesera batire ndi multimeter. Zida za digitozi ndi zotsika mtengo komanso zosavuta kugwiritsa ntchito ndipo zimapezeka m'masitolo ambiri amagetsi. Multimeter imatha kukuuzani za momwe betri yanu ilili (SOC) komanso ngati ili yabwino kapena yokonzeka kusinthidwa. Chinsinsi ndikumvetsetsa makonda osiyanasiyana a multimeter ndi zomwe akutanthauza pakuyesa batire.
Nayi chiwongolero chachangu pazosintha zosiyanasiyana za multimeter ndi momwe zimagwirira ntchito:
Mukuyang'ana makonzedwe a batire yagalimoto yama multimeter? Osayang'ananso kwina! Mphamvu yamagetsi ya batri yagalimoto imakhala pakati pa 15 ndi 20 volts. Mutha kuyesa batire lanu pokhazikitsa ma multimeter anu pamtundu wa 20V DC.
Samalani
Apa mudzakumana ndi madzi owopsa, choncho samalani. Choyamba muzimitsa galimotoyo ndipo onetsetsani kuti makiyi achotsedwa poyatsira. Kenako chotsani chingwe choyipa kuchokera ku batire ndi wrench kapena socket. Apa ndipamene mumalumikiza kutsogolo kwakuda kuchokera ku multimeter yanu.
Lumikizani choyesa chofiyira kumalo olowera batire lagalimoto pogwiritsa ntchito wrench kapena socket ina. Multimeter yanu tsopano iyenera kulumikizidwa ndi zikhomo zonse ziwiri.
Khazikitsani ma multimeter anu pamlingo woyenera
Onetsetsani kuti ma multimeter anu akhazikitsidwa pamlingo wolondola wamagetsi. Khazikitsani ku 20V, sikelo yomwe imatha kuwerenga mabatire onse a 12V ndi 6V mosavuta. Ngati muli ndi multimeter ya analogi, onetsetsani kuti singano yayikidwa pa zero musanayambe kuwerenga - mwanjira imeneyo, cholakwika chilichonse pa multimeter yanu chidzawoneka ngati chotsitsa, osati chosokoneza kuphatikizapo kuwerenga zabodza.
Yang'anani batri ndi katundu wochepa
Chotsatira ndikuchotsa zida zonse m'galimoto yanu ndikuyang'ana mphamvu ya batri pansi pa katundu wochepa. Kuti muchite izi, muyenera kupeza malo abwino ndi oipa pa batri. Kenako lumikizani waya wofiyira ku terminal yabwino komanso waya wakuda ku terminal yoyipa.
Ngati muwona ma volts 12 kapena kuposerapo pachiwonetsero chanu, izi zikutanthauza kuti chotengera chagalimoto yanu chikugwira ntchito bwino ndipo palibe vuto ndi batire. Ngati iwerenga chilichonse pansi pa 12 volts, vuto limakhala ndi makina ake opangira kapena ndi batire lokha. Mwachitsanzo, kuwerenga ma volts 11 kumatanthauza kuti batire yagalimoto yanu ili ndi 50% yotsalira, pomwe 10 volts ikutanthauza 20% yokha yomwe yatsala.
Yang'anani batri ndi katundu wambiri
Mukayesa batire yolemetsa, sinthani multimeter kukhala 20 volt DC. Ngati mulibe choyezera katundu wambiri, gwiritsani ntchito babu 100 watt m'malo mwake. Nyali ya 100W imakoka pafupifupi ma amps 8 kuchokera ku batri ikayatsidwa komanso pafupifupi 1 amp ikazima.
Njira yabwino yoyezera batri ndi babu ndikuyichotsa panyali yamoto kapena socket ya dome. Poyatsira nyale, gwirizanitsani mbali ina ya babuyo pansi ndi kukhudza mbali ina ya babuyo ndi choyesa cha mita (Chithunzi 2).
Khalani ndi wothandizira kuyatsa kuyatsa mukuyang'ana mita. Ngati palibe kutsika kwamagetsi, ndiye kuti batire ndi alternator zili bwino. Ngati dontho la voteji ndiloposa 0.5 volts, muli ndi kugwirizana koipa kwinakwake mu dongosolo lililonse.
DC motsutsana ndi AC
Izi mwina ndi zomwe mumazidziwa kwambiri. Pachifukwa ichi, mphamvu yachindunji ndi yachindunji, ndipo kusinthasintha kumasinthasintha. Mukayesa mabatire agalimoto, nthawi zonse mumagwiritsa ntchito magetsi a DC, onetsetsani kuti yayikidwa bwino!
Kukana (Ohm)
Parameter iyi imakuuzani kuchuluka kwa kukana komwe kulipo mu dera. Ohms ndi gawo loyezera kukana, kotero parameter iyi imatchedwa "Ohm". Parameter iyi ikhoza kukuthandizani kuyeza kukana mu mawaya ndi zigawo zina.
Mphamvu yamagetsi (V)
Kuyika uku kumakupatsani mwayi woyeza mphamvu yamagetsi pakati pa mfundo ziwiri pagawo. Mutha kuyesa izi ndi batire ndi alternator kuti muwonetsetse kuti ikugwira ntchito bwino. Izi zidzakhazikitsidwanso kuti ziwongolere magetsi (DC) poyesa mabatire agalimoto monga momwe amagwirira ntchito. (1)
Zamakono (A)
Tengani ma multimeter ndikupeza zomwe zikuchitika pano (A). Muyenera kuwona chizindikiro chaching'ono chomwe chikuwoneka ngati njoka ikuluma mchira - ichi ndi chizindikiro cha mphamvu zamakono. (2)
Kenako pezani batire zabwino (+) ndi zoipa (-) batire. Nthawi zambiri amalembedwa zofiira ndi zakuda motsatana. Ngati sichoncho, yang'anani zizindikiro za "+" ndi "-" pafupi ndi iwo.
Lumikizani imodzi mwama multimeter imatsogolera ku terminal yabwino ndi ina ku terminal yoyipa. Waya wa nsonga zofiira amalumikizidwa ku terminal yabwino, ndipo waya wakuda wakutsogolo amalumikizidwa ku terminal yoyipa.
Tsopano yang'anani zowonetsera pa multimeter yanu: ngati ikuwonetsa nambala pakati pa 10 ndi 13 amps, batri yanu ili bwino! Manambalawo adzakhala otsika ngati simunakwerepo posachedwa, koma ayenera kubwereranso pambuyo pothamanga. Kumbukirani kuti mabatire onse amatuluka pakapita nthawi, ngakhale akugwira ntchito bwino tsopano.
Onani zina mwazolemba zathu pansipa.
