LEEM-23 Multifunctional Bridge Experiment
Main luso magawo
1. Kukaniza mkono wa mlatho R1: Konzani zotsutsana zolondola: 10Ω, 100Ω, 1000Ω, 10kΩ, zomwe zimatembenuzidwa ndi kugwirizana kwa pulagi yafupikitsa, ndi kukana kulondola ndi ± 0.1%;
2. Kukaniza mkono wa Bridge R2: Konzani mabokosi otsutsa: 10 × (1000 + 100 + 10 + 1) Ω, kulondola kukana ndi: ± 0.1%, ± 0.2%, ± 1%, ± 2%;
3. Kukaniza mkono wa Bridge R3: Konzani mabokosi awiri otsutsa R3a, R3b, omwe amaikidwa mkati pawotchi yofanana yawiri-wosanjikiza, ndipo kukana kumasintha nthawi imodzi: 10 × (1000 + 100 + 10 + 1 + 0.1) Ω , kukaniza
Kulondola ndi: ± 0.1%, ± 0.2%, ± 1%, ± 2%, ± 5%;
4. Standard resistance RN: Miyezo yotsutsa ndi: 10Ω, 1Ω, 0.1Ω, 0.01Ω, ndi mfundo zolondola zotsutsa
Zina kuposa: ± 0.1%, ± 0.1%, ± 0.2%, ± 0.5%, akhoza kulumikizidwa kunja;
5. Kukana koyenera kuyesedwa: Rx imodzi: 1kΩ, 0.25W, kusatsimikizika: 0.1%;Rx kawiri: 0.2 ohm, 0.25W, kusatsimikizika: 0.2%.Zopinga ziwirizi zitha kugwiritsidwa ntchito poyesa mlatho kapena kuyesa ngati mlatho ukuyenda bwino.
6. Digital galvanometer: gwiritsani ntchito voltmeter yowonetsera digito 4 ndi theka: osiyanasiyana ndi 200mV, 2V.Kuwonetsa kulondola kwa galvanometer ya digito ndi: (0.1% osiyanasiyana ± 2 mawu).Galvanometer imatha kulumikizidwa kunja;
7. Mipikisano ntchito mphamvu magetsi: 0~2V chosinthika magetsi, 3V, 9V magetsi.
8. Pamene chidacho chikugwiritsidwa ntchito ngati mlatho wa mkono umodzi, mlingo woyezera: 10Ω~1111.1KΩ, mlingo wa 0.1;
9. Pamene chidacho chimagwiritsidwa ntchito ngati mlatho wamagetsi wamagetsi awiri, mlingo woyezera: 0.01~111.11Ω, 0.2 mlingo;
10. Njira yabwino ya mlatho wosagwirizana ndi 10Ω~11.111KΩ, ndipo cholakwika chovomerezeka ndi 0.5%;
11. Pokhazikitsa mlatho wosagwirizana, chidacho chiyenera kukhala ndi chojambulira chotsutsa kapena chipangizo chowongolera kutentha.
12. Mitundu yonse ya milatho yamagetsi yofanana ikhoza kusinthidwa.
