Taw qhia rau cov kev ua txhaum cai thiab kev kho cov txheej txheem ntawm cov neeg muaj kuab siv digital
Txog kev ua yuam kev ua yuam kev, nws yog ib qho tsim nyog los kuaj thawj zaug thiab txiav txim siab seb puas muaj qhov xwm txheej (txhua lub luag haujlwm), thiab tom qab ntawd qee cov haujlwm raws li cov teeb meem tshwj xeeb thiab daws cov teeb meem raws li.
Yog tias txhua tus muaj kev ua haujlwm tsis tuaj yeem ua haujlwm, lub zog hluav taws xob Circuit Court thiab A / D Converter Circuit Court yuav tsum tsom rau kev kuaj xyuas. Thaum kuaj xyuas lub zog hluav taws xob ntu, tshem tawm cov roj teeb, nias lub zog mus rau lub chaw ntsuas kev ntsuas thiab kev ntsuas tsis zoo ua rau lub zog ntawm lub zog (rau cov digital motimeter). Teem lub tes hloov mus rau Diode ntsuas ntau yam. Yog hais tias tus nqi tso tawm yog rau pem hauv ntej ntawm Diode, nws qhia tau tias lub zog hluav taws xob feem yog qhov zoo. Yog tias muaj kev sib txawv loj, nws txhais tau tias muaj teeb meem nrog lub zog hluav taws xob. Yog tias muaj kev qhib Circuit Court, tsom rau kev kuaj lub zog hloov, roj teeb, thiab lwm yam. Kev tshuaj xyuas ntawm A / D Converter tuaj yeem nqa tawm ib txhij nrog cov meter yooj yim, uas yog sib npaug rau DC meter lub taub hau ntawm ib tug analog multimeter. Cov txheej txheem kev kuaj xyuas tshwj xeeb yog raws li hauv qab no:
(1) tig cov ntawm cov meter 'ntsuas mus rau qis tshaj plaws dc voltage ntau.
(2) Ntsuas seb puas yog cov kev ua haujlwm hluav taws xob ntawm A / D Converter yog qhov qub. Raws li tus qauv ntawm A / D Converter siv hauv lub ntsuas, ntsuas nruab nrab ntawm V + tus lej ntawm tus nqi ntsuas nrog nws tus nqi raug saib xyuas yog tias lawv sib phim.
(3) Ntsuas cov ntaub ntawv hluav taws xob ntawm A / D Converter. Qhov siv hluav taws xob feem ntau siv cov multiveters digital multimeters tam sim no feem ntau 100 cv, uas yog, ntsuas lub DC voltage ntawm vref + thiab com. Yog tias nws deviates los ntawm 100mv lossis 1V, nws tuaj yeem hloov kho los ntawm sab nraud Potentiometer.
(4) Txheeb xyuas cov tshuaj saib thaum lub tswv yim yog xoom. Luv - Circuit Court Qhov chaw zoo hauv + thiab qhov ntsuas tsis zoo hauv {}}} 00 000 "lossis" 00.00 ".
(5) Tshawb xyuas cov hlua pluaj tag nrho ntawm cov zaub. Luv - Circuit Court Qhov kev ntsuas tus Pin ntawm kev sim lub davhlau ya nyob twg nrog lub zog hluav taws xob ua haujlwm, thiab tag nrho cov khoom lag luam digital nres. Txij li thaum DC voltage tau thov rau txhua qhov mob stroke, txhua tus tshuaj tua kab. Rau plaub - tus lej ntsuas meter, nws yuav qhia "1888", thiab rau tsib tus lej ntsuas cov meter, nws yuav qhia "18888". Yog tias muaj qhov tshwm sim ntawm cov stroke ploj, tshawb xyuas seb puas muaj kev sib tiv tauj ntawm cov ntawv tso tawm ntawm A / D Converter thiab cov ntawv nplaum txuas), thiab cov zaub.
