Kulondola kwa njira kumatanthauzidwa ngati peresentitage ya Full Scale range. Mtundu Wathunthu wa Scale umachokera ku -range mpaka osiyanasiyana ndipo ndi 2 * osiyanasiyana. Pamene gawo lolowera likuyikidwa ku 4 V, Mtundu Wathunthu wa Scale ndi -4 V mpaka 4 V = 8 V. Kuwonjezerapo chiwerengero cha Ma Bits Ochepa kwambiri chikuphatikizidwa. Kulondola kumatsimikiziridwa pamlingo wapamwamba kwambiri.

Pamene kulondola kumatchulidwa kuti ± 0.3% ya Full Scale range ± 1 LSB, ndipo zolowetsamo ndi 4 V, kupatukana kwakukulu komwe mtengo woyezera ungakhale ± 0.3% wa 8 V = ± 24 mV. ±1 LSB ikufanana ndi 8 V / 65536 (= chiwerengero cha LSB pa 16 bit) = ± 122 µV. Choncho mtengo woyezera udzakhala pakati pa 24.122 mV kutsika ndi 24.122 mV pamwamba kuposa mtengo weniweni. Mwachitsanzo, poika chizindikiro cha 3.75 V ndikuchiyeza mu 4 V, mtengo wake udzakhala pakati pa 3.774122 ndi 3.725878 V.
