Na'urar Gwaji ta LEEM-10 ta Halayen Mahadar PN

Gwaje-gwaje

1. A daidai wannan zafin, a auna halayen volt-ampere na gaba na mahaɗin PN kuma a ƙididdige ma'aunin Boltzmann;

2. Gabatarwar wutar lantarki ta I ba ta canzawa ba, an tsara taswirar VT na ƙarfin lantarki na gaba na mahadar PN, an ƙididdige ƙarfin ji, kuma an kiyasta faɗin tazarar band na kayan mahadar PN da aka auna;

3. Gwajin amfani: yi amfani da mahaɗin PN da aka bayar don auna zafin jiki da ba a sani ba;

4. Gwaji mai ƙirƙira: Dangane da bayanan gwaji, kimanta juzu'in jimla mai juzu'i na mahaɗin PN.

5. Gwajin bincike: Ka lura da tasirin girman wutar lantarki mai haɗawa.

Babban sigogin fasaha

1. Iri-iri na haɗin PN tare da marufi, gami da bututun silicon, bututun germanium, transistors NPN, da sauransu.

2. Jerin fitarwa na yanzu shine 10nA ~ 1mA, ana iya daidaitawa a sassa 4, daidaitawa mai kyau: mafi ƙarancin 1nA, ƙarfin tuƙi

Kimanin 5V, tsallake kalmomi ≤ kalma 1/minti;

3. Na'urar auna ƙarfin lantarki mai lamba 4 da 1/2 mai juriya mai ƙarfi, matakai biyu na juriya na ciki: 10MΩ, matakin juriya mai ƙarfi (fiye da 1GΩ), kewayon aunawa: 0~2V, ƙuduri: 0.1mV; rashin tabbas na aunawa: 0.1%± kalmomi 2.

4. Zafin gwaji: zafin ɗaki ~ 99℃, ma'aunin zafi na dijital: 0~100℃, ƙuduri 0.1℃;

5. Har da hita ta lantarki, kwalbar Dewar da kuma beaker.
