Tallaabooyinka rakibidda
1. Kahor intaadan rakibin qalabka, fadlan si taxaddar leh u akhri oo rakib qalabka sida ku xusan . Fiiro gaar ah: Wixii dhaawac ah ee uu sameeyay qofka iyo cawaaqib xumada kale ee ka dhalata rakibidda qaladka oo aan waafaqsanayn , mas'uul kama noqon doonno mana bixin doonno damaanad bilaash ah.
2. Qalabka ka soo saar sanduuqa; ku hagaaji raafka oo si kalsooni leh u dhig dhulka. (Iska caabbinta dhulka waa inay noqotaa < 4Ω).
3. Isticmaal multimeter-ka dijitaalka ah si aad u hubiso danabka sahayda, hubi in danabka sahayda uu waafaqsan yahay shuruudaha iyo furaha badhanka furuhu uu ku yaal booska "OFF". Kadib ku xidh korontada.
4. Geli calaamadda indhaha sida ku cad fariinta bandhigga. Furaha badhanka u rog booska "ON" oo fiiri heerka LED-ka ee guddiga hore. Ka dib marka tilmaamuhu uu noqdo cagaar, qalabku si caadi ah ayuu u shaqeynayaa. Kadib riix badhanka liiska ee ku yaal guddiga hore si aad u hubiso xuduudaha shaqada.
5. Ku xidh mitirka korontada indhaha dhammaadka soo saarista calaamadda indhaha adigoo adeegsanaya qalabka tijaabada fiber-ka ee caadiga ah, ka dibna cabbir awoodda soo saarista indhaha. Xaqiiji in awoodda soo saarista indhaha ee la cabbiray iyo awoodda la soo bandhigay ay isku mid yihiin oo ay gaareen qiimaha magacaaban. (Xaqiiji mitirka korontada indhaha inuu ku jiro booska tijaabada hirarka 1550nm; qalabka tijaabada fiber-ka indhaha waa kan la jaanqaadaya oo dusha sare ee isku xidhka ma laha wax wasakh ah.) Ka saar qalabka tijaabada fiber-ka indhaha ee caadiga ah iyo mitirka korontada indhaha; ku xidh qalabka shabakadda. Ilaa hadda, qalabka si buuxda ayaa loo rakibay oo laga hagaajiyay.
