Amazi Ashobora gucana buji, Nukuri?Nukuri!
Nukuri ko inzoka zitinya realgar?Nibinyoma!
Icyo tugiye kuganira uyu munsi ni:
Kwivanga birashobora kunoza ibipimo byukuri, nukuri?
Mubihe bisanzwe, kwivanga ni umwanzi usanzwe wo gupima.Kwivanga bizagabanya ibipimo byukuri.Mubihe bikomeye, gupima ntabwo bizakorwa mubisanzwe.Uhereye kuri iyi ngingo, kwivanga birashobora kunoza ibipimo byo gupima, nibinyoma!
Ariko, burigihe burigihe?Hoba harigihe kwivanga bitagabanya ibipimo byukuri, ahubwo bikanoza?
Igisubizo ni yego!
2. Amasezerano yo kwivanga
Dufatanije nibihe nyabyo, dukora amasezerano akurikira kubyerekeye kwivanga:
- Kwivanga ntabwo birimo ibice bya DC.Mubipimo nyabyo, kwivanga ni AC kwivanga, kandi iki gitekerezo kirumvikana.
- Ugereranije na voltage yapimwe DC, amplitude yo kwivanga ni nto.Ibi birahuye nibihe bifatika.
- Kwivanga ni ikimenyetso cyigihe, cyangwa agaciro kagereranijwe ni zeru mugihe cyagenwe.Iyi ngingo ntabwo byanze bikunze ari ukuri mubipimo bifatika.Nyamara, kubera ko kwivanga muri rusange ari ikimenyetso cyinshi cya AC ikimenyetso, kubintu byinshi bivanga, amasezerano ya zeru arumvikana mugihe kirekire.
3. Ibipimo byukuri bipima
Ibikoresho byinshi byo gupima amashanyarazi na metero ubu bifashisha AD ihindura, kandi ibipimo byabo byo gupima bifitanye isano rya bugufi no gukemura AD ihinduka.Muri rusange, AD ihindura AD ifite ibyemezo bihanitse bifite ibipimo byukuri byo gupima.
Ariko, imyanzuro ya AD ihora igarukira.Dufashe ko imiterere ya AD ari bits 3 na voltage yo gupima hejuru ni 8V, AD ihindura ihwanye nigipimo kigabanijwemo ibice 8, buri gice ni 1V.ni 1V.Ibipimo byo gupima iyi AD buri gihe ni integer, kandi igice cya cumi gihora gitwarwa cyangwa kijugunywa, gifatwa ko gitwarwa muriyi mpapuro.Gutwara cyangwa guta bizatera amakosa yo gupima.Kurugero, 6.3V irarenze 6V na munsi ya 7V.Ibisubizo byo gupima AD ni 7V, kandi hariho ikosa rya 0.7V.Twise ikosa AD ikosa ryo kubara.
Kugirango byoroherezwe gusesengura, twibwira ko igipimo (AD ihindura AD) ntayandi makosa yo gupima usibye ikosa rya AD.
Noneho, dukoresha umunzani ibiri isa kugirango dupime voltage ebyiri za DC zerekanwe ku gishushanyo 1 nta nkomyi (ibintu byiza) hamwe no kwivanga.
Nkuko bigaragara ku gishushanyo cya 1, ingufu za DC zapimwe ni 6.3V, naho ingufu za DC mu ishusho y’ibumoso nta nkomyi, kandi ni agaciro gahoraho mu gaciro.Igishushanyo kiri iburyo cyerekana icyerekezo kitajegajega gihindagurika, kandi hariho ihindagurika ryagaciro.Umuvuduko wa DC mu gishushanyo cyiburyo uhwanye na DC ya voltage mu gishushanyo cyibumoso nyuma yo gukuraho ikimenyetso cyo kwivanga.Umwanya utukura mubishushanyo byerekana ibisubizo byahinduwe na AD uhindura.
Umuyoboro mwiza wa DC utabangamiye
Koresha imbaraga za DC zibangamira agaciro kagereranijwe ka zeru
Kora ibipimo 10 byumurongo utaziguye mubibazo byombi mumashusho yavuzwe haruguru, hanyuma ugereranye ibipimo 10.
Igipimo cya mbere ibumoso gipimwa inshuro 10, kandi ibyasomwe ni kimwe buri gihe.Bitewe ningaruka zamakosa ya AD, buri gusoma ni 7V.Nyuma yo gupimwa 10 ugereranije, ibisubizo biracyari 7V.Ikosa ryo kubara AD ni 0.7V, naho ikosa ryo gupima ni 0.7V.
Igipimo cya kabiri iburyo cyahindutse cyane:
Bitewe no gutandukanya ibyiza nibibi bya interineti ya voltage na amplitude, ikosa ryo kubara AD riratandukanye ahantu hatandukanye.Muguhindura ikosa rya AD yo kubara, ibisubizo byo gupima AD bihinduka hagati ya 6V na 7V.Birindwi mu bipimo byari 7V, bitatu gusa ni 6V, naho impuzandengo y'ibipimo 10 yari 6.3V!Ikosa ni 0V!
Mubyukuri, nta kosa ridashoboka, kuko mwisi yisi, nta 6.3V ihamye!Ariko, hariho rwose:
Mugihe nta kwivanga, kubera ko buri gipimo cyo gupima ari kimwe, nyuma yo kugereranya ibipimo 10, ikosa ntirihinduka!
Iyo hari urugero rukwiye rwo kwivanga, nyuma yo gupimwa 10 ugereranije, ikosa rya AD yo kubara ryagabanijwe nurutonde rwubunini!Imyanzuro yatunganijwe neza na gahunda yubunini!Ibipimo byo gupima nabyo byanonosowe nuburyo bukurikirana!
Ibibazo by'ingenzi ni:
Nibimwe iyo voltage yapimwe nizindi ndangagaciro?
Abasomyi barashobora kwifuza gukurikiza amasezerano yerekeye kwivanga mu gice cya kabiri, bagaragaza kwivanga hamwe nuruhererekane rwimibare yimibare, bakarenza urugero kubangamira voltage yapimwe, hanyuma bakabara ibisubizo byapimwe kuri buri ngingo ukurikije ihame ryo gutwara AD ihinduka. , hanyuma ubare impuzandengo yagaciro yo kugenzura, mugihe cyose intera amplitude ishobora gutera gusoma nyuma yo kubara kwa AD guhinduka, kandi icyitegererezo cyinshi ni kinini bihagije (impinduka ya amplitude ihinduka ifite inzira yinzibacyuho, aho kuba indangagaciro ebyiri zibyiza nibibi ), kandi ubunyangamugayo bugomba kunozwa!
Birashobora kwemezwa ko mugihe cyose voltage yapimwe itari mubare rwose (ntabwo ibaho kwisi), hazabaho ikosa ryo kubara AD, nubwo ikosa rya AD ryaba rinini, mugihe cyose amplitude ya intambamyi irarenze ikosa rya AD yo kubara cyangwa iruta ireme ryibanze rya AD, bizatera ibisubizo byo gupima guhinduka hagati yindangagaciro ebyiri zegeranye.Kubera ko kwivanga ari byiza kandi bibi kugereranya, ubunini nibishoboka byo kugabanuka no kwiyongera birangana.Kubwibyo, mugihe agaciro nyako kegereye agaciro, amahirwe y agaciro azagaragara ni menshi, kandi azaba yegereye agaciro nyuma yo kugereranya.
Nukuvuga: agaciro kagereranijwe k'ibipimo byinshi (intervention bivuze agaciro ni zeru) bigomba kuba hafi y'ibisubizo byo gupimwa nta nkomyi, ni ukuvuga, ukoresheje ikimenyetso cyo guhuza AC gifite agaciro kagereranijwe ka zeru kandi ugereranije ibipimo byinshi bishobora kugabanya ihwanye na AD Quantize. amakosa, kunoza imiterere yo gupima AD, no kunoza neza ibipimo!
