APPENDIX C: ANALOG INPUT 4-20MA REFERENCE CHART
Analog 4-20Ma Gain/Offset Conversion Formula:
Gain = Sensor Range (High Value – Low Value) / 4
Offset = Sensor Low Value – Gain
Example: TH140 Humidity
Gain = (High Value (100) –Low Value (0)) / 4 = 25
Offset = (Sensor Low Value (0) – Gain (25)) = -25
