Ngokuqhelekileyo kubonakala ukuba abaninzi abaqalayo baphosa ukuchasana ngelixa belungisa isiphaluka, kwaye ichithwa kwaye i-welded. Enyanisweni, iye yalungiswa kakhulu. Logama nje uqonda iimpawu zomonakalo wokuchasa, akufuneki uchithe ixesha elininzi.
Ukuchasana lelona candelo lininzi kwizixhobo zombane, kodwa akusiyo icandelo elinomlinganiselo ophezulu womonakalo. Isekethe evulekileyo yolona hlobo luqhelekileyo lomonakalo wokuchasana. Kunqabile ukuba ixabiso lokumelana libe likhulu, kwaye ixabiso lokumelana liba lincinci. Eziqhelekileyo ziquka i-carbon film resistors, i-resistors yefilimu yesinyithi, i-resistors yenxeba yocingo kunye ne-inshurensi yomshuwalense.
Iindidi ezimbini zokuqala zokuxhathisa zezona zisetyenziswa kakhulu. Enye yeempawu zomonakalo wabo kukuba izinga lomonakalo wokuchasana okuphantsi (ngaphantsi kwe-100Ω) kunye nokuchasana okuphezulu (ngaphezulu kwe-100kΩ) kuphezulu, kunye nexabiso eliphakathi lokumelana (njengamakhulu ohms ukuya kumashumi e-kiloohms) Umonakalo omncinci kakhulu; Okwesibini, xa i-resistant-resistant-resistant zonakaliswe, zihlala zitshiswa kwaye zimnyama, ekulula ukuzifumana, ngelixa i-resistant-resistant-resistant-resistant inqabile.
Izichasi zeWirewound zihlala zisetyenziselwa umda ophezulu wangoku, kwaye ukuchasana akukhulu. Xa i-cylindrical wire resistors itshisa, ezinye ziya kuba mnyama okanye umphezulu uya kugqabhuka okanye uqhekeke, kwaye ezinye aziyi kuba nazikhondo. Izichasi zesamente luhlobo lwezixhasi zenxeba zocingo, ezinokuphuka xa zitshisiwe, ngaphandle koko akuyi kubakho zimpawu ezibonakalayo. Xa i-resistor ye-fuse ivutha, iqhekeza lesikhumba liya kuvuthelwa kwiindawo ezithile, kwaye ezinye azinamkhondo, kodwa aziyi kutshisa okanye zibe mnyama. Ngokwezi mpawu zingentla, unokugxila ekujongeni ukuchasana kwaye ufumane ngokukhawuleza ukuchasana okonakele.
Ngokweempawu ezidweliswe apha ngasentla, sinokuqala sijonge ukuba ngaba i-resistors ephantsi kwibhodi yesekethe itshise amanqaku amnyama, kwaye ke ngokweempawu uninzi lwabaxhathisi bavulekileyo okanye ukuxhathisa kuba kukhulu kunye ne-resistance ephezulu. zonakaliswa ngokulula. Singasebenzisa i-multimeter ukulinganisa ngokuthe ngqo ukuchasana kuzo zombini iziphelo ze-resistance high-resistance kwibhodi yesiphaluka. Ukuba ukuchasana okulinganisiweyo kukhulu kunokuxhatshazwa okuqhelekileyo, ukuchasana kufuneka konakaliswe (qaphela ukuba ukuchasana kuzinzile phambi komboniso Ekuqukumbeleni, kuba kunokubakho izinto ezihambelanayo ze-capacitive kwisiphaluka, kukho ukuhlawulwa kunye nenkqubo yokukhupha), ukuba ukuchasana okulinganisiweyo kuncinci kunokuxhatshazwa okuqhelekileyo, ngokuqhelekileyo kuhoywa. Ngale ndlela, ukuchasana konke kwibhodi yesiphaluka kulinganiswa kwakhona, kwaye nokuba iwaka "libulewe ngokungalunganga", umntu akayi kuphoswa.
