LEEM-25 Potentiometer Experiment

Ngā tawhā hangarau matua
1. Pūnaha hiko pumau DC: 4.5V, whakaaturanga matihiko toru-me te haurua, me te taputapu whakawhāiti iahiko;
2. Pūmanawa hiko paerewa: 1.0186V, tika ±0.01%, utu aunoa mō te pāmahana pumau;
3. Ine tere mamati: 5×10-4, 10-6, 10-8, 10-9A ka taea te whakarite i te aro ki ngā tere e whā;
4. Pouaka ātete: (0～10)×(1000+100+10+1)Ω, ±0.1%
5. E rua ngā EMF hei ine, pouaka pākahiko Nama 1, me te pouaka wehewehe ngaohiko i roto.
6. Ko te anga o te potentiometer tekau mā tahi-waea he mea hanga ki te plexiglass, he hanganga ā-roto ngāwari me te rahi iti;
7. He rite te rahi o ia waea ātete ki te kotahi mita, ā, ko te uara ātete he 10Ω;
8. Tekau ngā waea ātete kua takaihia ki runga i tētahi tokotoko plexiglass, kua whakaritea ki roto i tētahi pouaka mārama, ā, kua honoa raupapatia tetahi ki tetahi;
9. Ka takaihia te waea ātete tekau mā tahi ki runga i te kōpae ātete hurihuri, ā, ka wehea ōritetia te tauine kia 100 ngā wehenga. Mā te whakamahi i te vernier, ka taea te tika ki te 1mm; ko te ātete raupapa katoa he 110Ω.
10. Ka taea te whiriwhiri i tētahi potentiometer waea tekau mā tahi noa mō te whakamātautau
