LEEM-23 Multifunctional Bridge Experiment

Kufotokozera Kwachidule:

Chidacho chimagwirizanitsa ntchito zosiyanasiyana za mlatho wa mkono umodzi, mlatho wa mikono iwiri, ndi mlatho wosagwirizana, womwe umatha kuzindikira mawaya awiri, waya atatu, ndi miyeso ya kukana kwa waya, lolani wogwiritsa ntchito kukhala "mbuye" pogwiritsira ntchito milatho. .

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 pazitsulo ziwiri zosanjikiza, ndipo kukana kumasintha nthawi imodzi: 10 × (1000 + 10 + 1 + 0.1) Ω, kukana, kukana
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.
