RH
RL
▶ This is a range input correction into dry temperature.
▶ Wet temperature and humidity have The same range input correction.
▶ S.PV = Sensor Temperature, B.PV = The temperature after correction, RL = Range Low,
RH = Range High
▶ POINTn.DPV = Basic Temperature, POINTn.DDV = Correction Temperature
( n = 1, 2, 3, 4 )
▶ B.PV of the RL ~ POINT1 range.
= S.PV + POINT1.DDV
▶ B.PV of the POINT1 ~ POINT2 range.
= S.PV + ( S.PV – POINT1.DPV ) X + POINT1.DDV
▶ B.PV of the POINT2 ~ POINT3 range.
= S.PV + ( S.PV – POINT2.DPV ) X + POINT2.DDV
▶ B.PV of the POINT3 ~ POINT4 range.
= S.PV + ( S.PV – POINT3.DPV ) X + POINT3.DDV
▶ B.PV of the POINT4 ~ RH range.
= S.PV + POINT4.DDV
