N’chifukwa chiyani mita yoyezera madzi imasonyeza mtengo ngakhale chitolirocho chitakhala chosasunthika?

Izi zimatchedwa zero drift, zomwe zimachitika kawirikawiri pazida zakumunda. Nthawi zambiri zimachitika chifukwa cha dothi la ma elekitirodi, kusintha pang'ono kwa kutentha kapena kusokonezeka kwakunja.
Yankho lake ndi losavuta komanso lotetezeka: tsekani valavu kwathunthu, onetsetsani kuti chitolirocho chadzaza ndi madzi ndipo madzi ake ndi osasinthasintha, kenako chitani kuwerengera zero pa chotumizira. Mukakhazikitsanso mfundo ya zero, mitayo idzabwerera ku zero molondola. Kuwerengera zero nthawi zonse kumalimbikitsidwa kuti musunge kulondola kwa nthawi yayitali.
