LEEM-21 Teko ea Kopano ea Digital Multimeter

Tlhaloso e Khutšoanyane:

Sesebelisoa se hlalosa molao-motheo oa ts'ebetso oa "analog-to-digital conversion chip" ea ICL7107, le mokhoa oa ho lekanya lipalo tsa 'mele tse kang voltage, resistance, le boleng ba hona joale, le ho sebelisa li-voltage dividers, shunts le binning resistors ho lekanya voltage, ho hanyetsa, le boleng ba hona joale.Teko ea moralo oa katoloso, rala le ho metha boleng ba hFE ba triode le boleng ba ho theoha ha motlakase oa pele oa diode.
