Qalabka Tijaabada LEEM-10 ee Astaamaha Isgoyska PN

Tijaabooyin

1. Heerkulka isku midka ah, cabbir sifooyinka volt-ampere ee hore ee isgoyska PN oo xisaabi joogtada Boltzmann;

2. Haddalka hore ee I isma beddelin, qalooca VT ee danabka hore ee isgoyska PN waa la sawiray, xasaasiyadda waa la xisaabiyay, ballaca farqiga band-ka ee walxaha isgoyska PN ee la cabbirayna waa la qiyaasay;

3. Tijaabada codsiga: isticmaal isgoyska PN ee la bixiyay si aad u cabbirto heerkulka aan la garanayn;

4. Tijaabo cusub: Sida laga soo xigtay xogta tijaabada, qiyaas hadda isku-dhafka rogan ee isgoyska PN.

5. Tijaabo sahamin ah: Fiiri saameynta cabbirka qulqulka isku-dhafka ah.

Xuduudaha farsamada ugu muhiimsan

1. Kala duwanaansho kala duwan oo isku-xidhka PN ah oo leh baakado, oo ay ku jiraan tuubooyinka silikoon, tuubooyinka germanium, transistors-ka NPN, iwm.;

2. Kala duwanaanshaha wax soo saarka hadda jira waa 10nA ~ 1mA, oo lagu hagaajin karo 4 qaybood, hagaajin fiican: ugu yaraan 1nA, danab wadista

Ku dhawaad ​​5V, ka bood ereyada ≤ 1 eray/daqiiqo;

3. Voltmeter dijitaal ah oo leh iska caabin aad u sarreeya oo 4-1/2 lambar ah, laba heer oo iska caabin gudaha ah: 10MΩ, heer iska caabin aad u sarreeya (ka weyn 1GΩ), baaxadda cabbirka: 0~2V, xallinta: 0.1mV; hubanti la'aanta cabbirka: 0.1%± 2 eray.

4. Heerkulka tijaabada ah: heerkulka qolka ~ 99℃, heerkulbeegga dhijitaalka ah: 0~ 100℃, xallinta 0.1℃;

5. Waxaa ku jira kuleyliyaha korontada, dhalada Dewar iyo weelka.
