LEEM-2 Kupanga kwa Ammeter ndi Voltmeter
Cholozera mtundu DC ammeter ndi voltmeter ali refitted ku mutu mita. Mutu wa mita nthawi zambiri umakhala wa magnetoelectric galvanometer, womwe umangolola kuti mulingo wa micro ampere kapena milliampere udutse. Nthawi zambiri, zimatha kuyeza zochepa kwambiri pakali pano komanso magetsi. Pogwiritsa ntchito moyenera, iyenera kusinthidwa kuti ikulitse kuyeza kwake ngati ikufuna kuyeza kwamphamvu kapena magetsi. Mamita osinthidwa amayenera kuwerengedwa ndi mita yofananira ndipo mulingo wake wolondola uyenera kutsimikizika. Chida ichi chimapereka zida zonse zoyeserera pobwezeretsanso ammeter yaying'ono mu milliammeter kapena voltmeter. Zomwe zili zoyesera ndizolemera, lingaliro ndi lomveka, lokhazikika komanso lodalirika, komanso kapangidwe kake ndi kololera. Itha kugwiritsidwa ntchito makamaka pakuyesera kwakukula kwa ophunzira asukulu yapakatikati kapena kuyesera kwaukadaulo waukoleji ndi kuyeserera kapangidwe.
Ntchito
1. Mvetsetsani kapangidwe kake ndi kagwiritsidwe ntchito ka microamp galvanometer;
2. Phunzirani momwe mungakulitsire muyeso wa galvanometer ndikumvetsetsa tanthauzo lakumanga multimeter;
3. Phunzirani njira yosinthira mita yamagetsi.
Zofunika
| Kufotokozera | Zofunika |
| Mphamvu yamagetsi ya DC | 1.5 V ndi 5 V |
| DC yaying'ono galvanometer | muyeso osiyanasiyana 0 ~ 100 μA, kukana kwamkati pafupifupi 1.7 kΩ, kulondola kalasi 1.5 |
| Digital voltmeter | mitundu yoyezera: 0 ~ 1.999 V, resolution 0.001 V |
| Digital ammeter | miyeso iwiri yoyesera: 0 ~ 1.999 mA, kukonza 0.001 mA; 0 ~ 199.9 μA, resolution 0.1 μA. |
| Kukaniza bokosi | osiyanasiyana 0 ~ 99999.9 Ω, resolution 0.1 Ω |
| Potentiometer yosinthasintha | 0 ~ 33 kΩ mosinthika mosinthika |
