Uvavanyo lwe-LEEM-21 Digital Multimeter Assembly Experiment Umfanekiso oPhambili

Uvavanyo lweNtlanganiso yeDijithali ye-LEEM-21 Multimeter

Inkcazo emfutshane:

Esi sixhobo sichaza umgaqo wokusebenza kwe-analog-to-digital conversion chip ye-ICL7107 enamanani amathathu anesiqingatha, kunye nendlela yokulinganisa ubungakanani obusisiseko obufana ne-voltage, resistance, kunye namaxabiso angoku, kwaye sisebenzisa izahluli ze-voltage, ii-shunts kunye nee-binning resistor ukulinganisa i-voltage, resistance, kunye namaxabiso angoku. Uvavanyo loyilo lolwandiso lwe-Range, uyilo kunye nokulinganisa ixabiso le-hFE le-triode kunye nexabiso le-forward voltage drop ye-diode.
