1. Ntsuas qhov tsaus nti tiv thaiv tus nqi
Cov txheej txheem ntawm kev ntsuas qhov ntsuas qhov ntsuas qhov tsaus ntuj: Npog lub ntsej muag photosensitive ntawm photoresistor nrog ib daim ntawv dub. Thaum lub sij hawm ntsuas, tus pointer ntawm digital multimeter yuav tsum nyob twj ywm tsis hloov, thiab tus nqi kuj nyob ze rau infinity. Qhov loj dua qhov tsaus nti tiv thaiv tus nqi, qhov ua tau zoo ntawm photoresistor. Zoo; yog tias tus nqi no tsawg heev los yog ze rau xoom, nws txhais tau hais tias lub photoresistor tau raug hlawv los ntawm kev puas tsuaj thiab siv tsis tau lawm.
2. Ntsuas tus nqi ntawm lub teeb
Tig lub qhov rais xaim hluav taws xob ntawm photoresistor mus rau lub teeb ci. Lub sijhawm no, tus pointer ntawm multimeter yuav tsum viav vias los ntawm cov npoo loj, thiab tus nqi kuj yuav txo qis. Qhov me dua tus nqi kuj, qhov kev ua tau zoo ntawm photoresistor; Kev ua haujlwm ntawm photoresistor tsis zoo; Yog hais tias tus nqi kuj yog infinite, nws qhia tau hais tias lub sab hauv qhib Circuit Court ntawm photoresistor puas lawm, thiab nws yuav siv tsis tau lawm.
