Kukho umahluko okufutshane wamandla ombane weebhetri xa utshaja kwaye ukhupha, nto leyo ibangela ukulingana kwesi silinganisi esisebenzayo. Xa umahluko wombane webhetri osecaleni ufikelela kwi-0.1V okanye ngaphezulu, umsebenzi wokulinganisa we-trigger wangaphakathi uyenziwa. Iya kuqhubeka isebenza de umehluko wombane webhetri osecaleni uyeke ngaphakathi kwe-0.03V.
Impazamo yokupakisha ibhetri iya kutsalwa kwakhona kwixabiso elifunekayo. Iyasebenza ukunciphisa iindleko zokugcina ibhetri. Inokulinganisa ngokubonakalayo amandla ombane ebhetri, kwaye iphucule ukusebenza ngokupheleleyo kwepakethi yebhetri.
