Zafin ƙasa:
Nau'in wutar lantarki (0 ～ 5V fitarwa):
R = V / 5 × 100%
(R shine ƙimar danshin ƙasa kuma V shine ƙimar ƙarfin fitarwa (V))
Nau'in na yanzu (fitarwa 4 ~ 20mA):
R = (I-4) / 16 × 100%
(R shine ƙimar danshin ƙasa, ni ne ƙimar fitarwa na yanzu (mA))
Yanayin ƙasa:
Nau'in wutar lantarki (0 ～ 5V fitarwa):
T = V / 5 × 70-20
(T shine ƙimar zafin jiki da aka auna (℃), V shine ƙimar ƙarfin fitarwa (V), wannan dabarar tayi daidai da kewayon ma'auni -20 ℃ 50 ℃)
