LEEM-21 Digital Multimeter Assembly Experiment

Lus piav qhia luv luv:

Cov cuab yeej piav qhia txog lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm peb-thiab-ib-ib-nrab-tus lej analog-rau-digital hloov dua siab tshiab nti ICL7107, thiab yuav ua li cas ntsuas lub cev muaj nuj nqis xws li voltage, tsis kam, thiab qhov tseem ceeb tam sim no, thiab siv voltage dividers, shunts thiab binning resistors los ntsuas qhov voltage, tsis kam, thiab tam sim no tus nqi.Range extension tsim kev sim, tsim thiab ntsuas tus nqi hFE ntawm triode thiab tus nqi hluav taws xob rau pem hauv ntej ntawm diode.
