1. Indlela efanelekileyo yokulinganisa ye-resistor esisigxina
Kubaqeshwa, ukutshitshiswa kwabo kungekuphela kobuchule esisisiseko kwisondlo se-elektroniki, kodwa nenyathelo eliphambili ukuqinisekisa ukusebenza kwesiphaluka esiqhelekileyo sesekethe.Okokuqala, xa usebenzisa i-Multimeter yokulinganisa ukunganyangeki, indlela yokusebenza efanelekileyo kukudibanisa uvavanyo ezimbini kwiziphelo zozibini.Ngeli xesha le nkqubo, imilinganiselo elungileyo nengalunganga yendlela yokuziphatha ayichaphazeli iziphumo zomlinganiso.Ukwenzela ukuphucula ukuchaneka komlinganiso, kubalulekile ukukhetha uluhlu olufanelekileyo.Ixabiso elichanekileyo lomvuzo kufuneka likhokele ekukhetheni uluhlu lokuqinisekisa ukuba isikhombisi semilinganiselo iwela embindini woluhlu, oko kukuthi, phakathi kwenxalenye epheleleyo, ukuze isebenzise inxenye epheleleyoye-OHM yema ukunciphisa iimpazamo zokufunda..
Uluhlu lweempazamo ezivunyiweyo zomntu ngamnye luyahluka ngokwenqanaba lokuchaneka, ezi- ± 5%, ± 10%, kunye ± 20%.Oku kuthetha ukuba xa kuthathwa umlinganiso, ukuphambuka phakathi kwexabiso elilinganisiweyo kunye nexabiso elifanelekileyo lomkhuseli kufuneka kube ngaphakathi kolu luhlu.Imilinganiselo ngaphandle kolu luhlu lunokubonisa ukuba ukuxhathisa kutshintshile kwaye akusahlangabezana neenkcazo zayo zoqobo.
Ngokwenene, ezinye iinkcukacha kufuneka ziqwalaselwe ukuqinisekisa ukuchaneka kwemilinganiselo.Umzekelo, xa ulinganisa amaxabiso aphezulu okuxhathisa (ngentla apha, i-tins ye-Kω), kuphephe ukuchukumisa i-Probe kunye nenxalenye yokuhlela kwizandla zakho ukunqanda ukunganyangeki komgangatho.Ukongeza, ngaphambi kokulinganisa, kufuneka kugcinwe iBhodi yeSiphaluka kwaye okungenani isiphelo esinye sikhutshiwe ukuphepha ukuphazamiseka kwezinye izinto kwisekethe.
2. Isicwangciso esibonisa ukumelana nesamente
Ngenxa yesakhiwo esikhethekileyo sayo kunye nezixhobo, abaphathi beebhulukwana ezisetyenziswa ngokubanzi kwiimeko ezifuna ukubekwa kweMisebenzi ephezulu.Indlela yokufumana indawo yokuhlola i-cemeces ngokuqinisekileyo iyafana neyamkelayo eqhelekileyo.Oku kugxininisa ukubaluleka kweendlela zokulinganisa okusiseko zokuchasana nokuzikhumbuza ukuba banokusebenzisa imigaqo esisiseko efanayo yokuphathwa kakubi xa bethetha ngeendlela ezahlukeneyo zokuxhathisa.
3. Itekhnoloji yokufumana amanqaku
Njengenxalenye yesikhuselo sezokhuseleko, i-fuse tousetor inokukhuphela ngokuzenzekelayo xa isekethe ilayishwe ngaphezulu ukuthintela ukonakala kakhulu.Xa umphezulu womthi wefuse ubonakala emdaka okanye watshiswa, ihlala ithetha ukuba ukugeleka kwangoku kungaphezulu kwexabiso elithile.Kwelinye icala, ukuba i-fuse yothusa ayibonisi umkhondo phezu kwayo kodwa ivulekile, oku kunokubonisa ukuba okwangoku kungaphezulu nje kwenqanaba le-fuse elichithiweyo.I-R × 1 yesikali se-Multimeter sisixhobo esisebenzayo sokugweba umgangatho womphezulu we-fuse.Xa ixesha lokulinganisa, esinye isiphelo somphezulu we-fuse kufuneka sinqatshelwe kwisekethe.Ukuba ixabiso lokuchasana alinasiphelo, libonisa ukuba i-fuse yophindaphindo ayiphumelelanga.Ukongeza, ngexesha lokulungiswa okuthe tye, ngamanye amaxesha kufumanisa ukuba i-fuse yokurhola iqhekezwe kwaye ijikelezwe emfutshane, nayo kufuneka ithathelwe ingqalelo xa kuhlolwa.
4. UKUHLAZIYELWA NOKUVAVANYELWA KWEEMPAHLA
Njengomntu oguquguqukayo oqhelekileyo, intsebenzo ye-poterisometer ichaphazela ngokuthe ngqo ukusebenza kohlengahlengiso lwesekethe.Inyathelo lokuqala lokukhangela i-potikometer kukujonga ukuba ujikelezo lweqhina lugudileyo kwaye nokuba umsebenzi wokutshintsha uyaguquka.Ukongeza, isandi esivelisiweyo xa i-switch isebenza ikwayindlela yokugweba umgangatho wayo.Xa usebenzisa i-Multeter ukulinganisa ukunganyangeki, kuya kufuneka ukhethe uluhlu olufanelekileyo ngokusekwe ekuchazeni kwe-potentionatter, kwaye uqinisekise ukuba iyahambelana nexabiso le-PROOT ngokulinganisa zombini iziphelo zombini.Ukujikeleza kwe-shaft ye-potiometer kufuneka igudile, kwaye ixabiso lokuchasana kufuneka litshintshe ngokuqhubekayo ngexesha lokujikeleza ngaphandle kokutsiba.Ukuba unxibelelwano lwangaphakathi oluhlwempuzekileyo lwe-poterikometer lufumaneka ngexesha lovavanyo, i-poterikometer kufuneka ithathwe njengeyonakaliswe.
