Momwe mungayesere batire ya wotchi ndi multimeter (chilolezo)
Zamkatimu
Mabatire ang'onoang'ono a wotchi, omwe amadziwikanso kuti mabatani a mabatani, ndi mabatire ang'onoang'ono a cell single amatha kugwiritsidwa ntchito ndi mitundu yosiyanasiyana yamagetsi. Mutha kupeza mabatire ozungulira awa pa mawotchi, zoseweretsa, zowerengera, zowongolera zakutali, ngakhale mabokosi apakompyuta apakompyuta. Zodziwika bwino ngati mitundu ya ndalama kapena mabatani. Nthawi zambiri, batire ya cell cell ndi yaying'ono kuposa batire ya cell cell. Mosasamala kukula kapena mtundu, mungafunike kuyang'ana mphamvu ya batire ya wotchi yanu.
Chifukwa chake, lero ndikuphunzitsani momwe mungayesere batire ya wotchi yanu ndi ma multimeter.
Kawirikawiri, kuti muwone mphamvu ya batri, choyamba ikani multimeter yanu ku DC voltage setting. Ikani chowongolera chofiira cha multimeter pa batire yabwino. Kenako ikani waya wakuda kumbali yolakwika ya batire. Ngati batire ili ndi charger yokwanira, multimeter imawerengera pafupi ndi 3V.
Mitundu yosiyanasiyana ya batri yamawotchi
Pali mitundu itatu yosiyanasiyana yamabatire owonera omwe amapezeka pamsika. Iwo ali ndi mtundu wosiyana wa magetsi, ndipo kukula kwake ndi kosiyana. Mitundu iyi imatha kudziwika ngati mabatire a ndalama kapena mabatani. Kotero apa pali ma voltages a mabatire atatuwa.
| Mtundu wama batri | Voltage yoyamba | Mphamvu yosinthira batri |
| Lithium | 3.0V | 2.8V |
| siliva oxide | 1.5V | 1.2V |
| Zamchere | 1.5V | 1.0V |
Kumbukirani: Malinga ndi tebulo pamwambapa, batire ya lithiamu ikafika 2.8V, iyenera kusinthidwa. Komabe, chiphunzitsochi sichigwira ntchito ku batri ya lithiamu ya Renata 751. Ili ndi magetsi oyambirira a 2V.
Zomwe muyenera kudziwa musanayese
M'chigawo chino, mudzatha kuphunzira njira ziwiri zowunika mphamvu ya batri.
- Kuyesa koyamba
- Kuyesa katundu
Kuyesa koyamba ndi njira yachangu komanso yosavuta yowonera mphamvu ya batire la wotchi yanu. Koma poyesa pansi pa katundu, mukhoza kuona momwe batri linalake limachitira ndi katundu.
Pachifukwa ichi, batire la batri likhala ndi katundu wa 4.7 kΩ. Katunduyu akhoza kusiyanasiyana kutengera mtundu ndi kukula kwa batire. Sankhani katundu molingana ndi kutulutsa kwa batire. (1)
Chimene mukusowa
- Digital multimeter
- Bokosi losinthika lokana
- Seti ya zolumikizira zofiira ndi zakuda
Njira 1 - Kuyesa Koyamba
Iyi ndi njira yosavuta yoyesera katatu yomwe imangofunika multimeter. Choncho tiyeni tiyambe.
Gawo 1. Konzani ma multimeter anu
Choyamba, ikani ma multimeter kukhala ma voliyumu a DC. Kuti muchite izi, tembenuzirani kuyimba ku chilembo V.DC chizindikiro.
Khwerero 2 - Kuyika Zotsogolera
Kenako gwirizanitsani kutsogolo kofiira kwa multimeter ku positi ya batri yabwino. Kenako gwirizanitsani waya wakuda ku mtengo woipa wa batri.
Kuzindikira zabwino ndi zoyipa za batire ya wotchi
Mabatire ambiri owonera ayenera kukhala ndi mbali yosalala. Iyi ndi mbali yolakwika.
Mbali inayo ikuwonetsa chizindikiro chowonjezera. Izi ndi kuphatikiza.
Gawo 3 - Kuwerenga Kumvetsetsa
Tsopano onani kuwerenga. Kwa chiwonetserochi, tikugwiritsa ntchito batri ya lithiamu. Chifukwa chake kuwerenga kuyenera kukhala pafupi ndi 3V poganizira kuti batire ili ndi chaji. Ngati kuwerenga kuli pansipa 2.8V, mungafunike kusintha batire.
Njira 2 - Kuyesa Katundu
Mayesowa ndi osiyana pang'ono ndi mayeso am'mbuyomu. Apa mudzafunika kugwiritsa ntchito chotchinga chosiyana, zolumikizira zofiira ndi zakuda ndi multimeter. Monga tanena kale, pamayesowa timagwiritsa ntchito 4.7 kΩ yokhala ndi chipika chosiyana.
Langizo: Bokosi lotsutsa losinthika limatha kupereka kukana kokhazikika kudera lililonse kapena chinthu chamagetsi. Mlingo wokana ukhoza kukhala kuchokera pa 100 Ohm mpaka 470 kOhm.
Khwerero 1 - Konzani ma multimeter anu
Choyamba, ikani multimeter ku zoikamo za DC voltage.
Khwerero 2. Lumikizani chipika chotsutsana ndi multimeter.
Tsopano gwiritsani ntchito zolumikizira zofiira ndi zakuda kuti mulumikizane ndi ma multimeter ndi ma variable resistance unit.
Gawo 3 - Ikani Resistance
Kenako ikani unit yotsutsa ku 4.7 kΩ. Monga tanena kale, kukana kumeneku kumatha kusiyanasiyana malinga ndi mtundu ndi kukula kwa batire ya wotchiyo.
Khwerero 4 - Kuyika Zotsogolera
Kenako gwirizanitsani waya wofiyira wa unit resistance ku post positive ya batire ya wotchi. Lumikizani waya wakuda wa unit yotsutsa ku batire yolakwika.
Gawo 5 - Kuwerenga Kumvetsetsa
Pomaliza, ndi nthawi yoti muwone umboni. Ngati kuwerenga kuli pafupi ndi 3V, batire ndi yabwino. Ngati kuwerenga kuli pansi pa 2.8V, batire ndiyoyipa.
Kumbukirani: Mutha kugwiritsanso ntchito njira yomweyo ku silver oxide kapena alkaline batire popanda vuto lalikulu. Koma kumbukirani kuti mphamvu yoyambira ya silver oxide ndi mabatire a alkaline ndi yosiyana ndi yomwe yawonetsedwa pamwambapa.
Kufotokozera mwachidule
Mosasamala mtundu wa batri kapena kukula kwake, nthawi zonse muzikumbukira kuyesa magetsi molingana ndi njira zoyesera pamwambapa. Mukayesa batri ndi katundu, imapereka lingaliro labwino la momwe batire linalake limayankhira katundu. Chifukwa chake, iyi ndi njira yabwino yodziwira mabatire abwino a wotchi. (2)
Onani zina mwazolemba zathu pansipa.
- Momwe mungayesere batire ndi multimeter
- 9V multimeter kuyesa.
- Momwe mungagwiritsire ntchito multimeter kuti muwone mphamvu ya mawaya amoyo
