Walxaha kuleyliyaha foornada waa gariiradaha xagga sare iyo hoose ee foornada korontada ku shaqeysa ee kululeysa oo dhalaalaysa casaan markaad shideyso. Haddii foornadaadu aanay shidmin, ama ay dhibaato kaa haysato heerkulka foornada marka aad wax karinayso, dhibaatadu waxa ay noqon kartaa dhibaato kulka foornada. Isticmaal multimeter si aad u tijaabiso sii socoshada kuleyliyaha foornada si aad u go'aamiso haddii kuleyliyuhu si fiican u shaqeeyo. Tani waxay qiimeyn kartaa in cunsurka uu si sax ah uga helayo calaamadaha korantada ee foornada. Tijaabooyin kale oo aasaasi ah waxaa ka mid ah in jir ahaan loo hubiyo gariiradda iyo iskutallaab ku hubinta heerkulka heerkulka foornada.
1. Ka saar foornada, ka saar walxaha kuleyliyaha foornada, tijaabi oo qiimee sii socoshada kuleyliyaha foornada adigoo isticmaalaya multimeter, oo waxay kuu sheegi doonaan haddii walxaha kuleylku shaqeynayo.
2 Go'aami tuubada kululaynta foornada ee sare iyo hoose ee foornada. Walxaha kuleyliyuhu waa gariir weyn oo xagga sare iyo hoose ee foornada. Fur albaabka foornada, ka saar birta oo ka saar tuubada kululaynta.
Tubooyinka kululaynta foornada waxay ku yimaadaan qaabab iyo cabbiro kala duwan, laakiin tillaabooyinka guud waa isku mid iyadoon loo eegin astaantaada ama moodelkaaga. Marka foornada la damiyo, walxaha kuleyliyuhu waa madow ama cawl. Marka foornada la shido, walxahan waxay dhalaalaan orange.
3. Deji garaaca mitirka cabbirka meesha ugu hooseeya ee ohm (Ω). Geli fiilada cas godka cas, fiilada madowna geli booska madow ee dusha sare ee mitirka. Daar qalabka Ka dib, u rog garaaca multimeterka si uu ugu dhejiyo ohm, kaas oo ah halbeegga cabbirka ee loo isticmaalo cabbirka caabbinta. Isticmaal lambarka ugu hooseeya ee laga heli karo baaxadda ohm si aad u tijaabiso kuleyliyahaaga. (U beddelo caabbinta u dhiganta iyadoo loo eegayo tamarta iyo awoodda kuleyliyaha foornada).
Haddii aad xiisaynayso walxaha kuleyliyaha shiilan, fadlan nala soo xiriir si toos ah!
