Kunomehluko we-voltage oseduze wamabhethri lapho ishaja futhi ishajwa, okubangela ukulingana kwalesi silinganisi esishintshayo. Uma umehluko wevolthi yebhethri oseduze ufinyelela ku-0.1V noma ngaphezulu, umsebenzi wokulinganisa wokucupha wangaphakathi uyenziwa. Izoqhubeka nokusebenza kuze kube yilapho umehluko we-voltage eseduze uyama phakathi kuka-0.03V.
Iphutha levolumu yephakethe lebhethri nalo lizodonswa libuyiselwe kunani elifunekayo. Kuyasebenza ukwehlisa izindleko zokulungisa ibhethri. Ingakwazi ukulinganisa ngokuphawulekayo amandla omthamo webhethri, futhi ithuthukise ukusebenza kahle okuphelele kwephakethe lebhethri.
