Isingeniso:

I-EM501577 ivavanya ukukwazi kwebhetri ukukrazula injini.
Umvavanyi utsala okwangoku kwibhetri ngelixa elinganisa inqanaba lombane.
Umgangatho wombane webhetri elungileyo uya kuhlala uzinzile phantsi komthwalo, kodwa ibhetri enesiphene iya kubonisa ukulahleka okukhawulezayo kumbane.
Ubungakanani bebhetri (umlinganiselo weCCA) kunye nobushushu buya kuchaphazela iziphumo zovavanyo.
Umvavanyi webhetri: Uvavanya ukukwazi kwebhetri ukukruqa injini.
