LEEM-21 Digital Multimeter Assembly Experiment

Inkcazelo emfutshane:

Isixhobo sichaza umgaqo-siseko wokusebenza we-analog-to-digital conversion chip ICL7107, kunye nendlela yokulinganisa ubungakanani bomzimba obusisiseko obufana nombane, ukuxhathisa, kunye namaxabiso angoku, kwaye kusetyenziswa izahluli zombane, i-shunts kunye i-binning resistors ukulinganisa amandla ombane, ukuxhathisa, kunye namaxabiso angoku.Uvavanyo loyilo lolwandiso loluhlu, uyilo kunye nokulinganisa ixabiso le-hFE le-triode kunye nexabiso le-voltage yangaphambili yokuhla kwe-diode.
