Enye into ephawulekayo yale mveliso kukukwazi ukuphatha imidiya enobudlova. Ulwelo olonakalisayo lunika imiceli mngeni ebalulekileyo kumlinganiselo wenqanaba njengoko lunokonakalisa izinzwa kwaye luchaphazele ukuchaneka kwazo. Ukuntywiliselwaigeyiji yenqanabas yoyise lo mngeni ngokusebenzisa inkqubo yesikhokelo somoya. Ngokuhlukanisa i-sensor ekunxibelelaneni ngokuthe ngqo kunye neendaba ezinobundlobongela, i-transmitter iqinisekisa ixesha elide kunye nokuchaneka kwenkqubo yokulinganisa. Ukuntywiliselwaigeyiji yenqanabas balungile ekulinganiseni uluhlu oluncinci kunye oluphakathi. Uyilo lwayo luvumela ukuba ukulinganisa ngokuchanekileyo amanqanaba olwelo kwizicelo ezingadingi uluhlu olubanzi. Esi sikhundla senza ukuba ilunge kumashishini afana nokusetyenzwa kweekhemikhali ezidla ngokuphatha iibhetshi ezincinci ukuya eziphakathi.
Isishwankathelo, igeyiji yenqanaba lokuntywiliselwa sisisombululo esikhethekileyo somlinganiselo oyilelwe ukoyisa imiceli mngeni enxulumene nobushushu obuphezulu kunye nolwelo oludlekayo. Ngenkqubo yesikhokelo yerhasi entsha kunye nokukwazi kwayo ukuphatha imilinganiselo yoluhlu oluncinci ukuya oluphakathi, ibonelela ngomlinganiselo ochanekileyo nothembekileyo womgangatho wolwelo kumashishini ahlukeneyo.
