- Take samples from the process liquid and take a field sample.
-
Repeat as many times as needed.
To calculate offset and gain you need at least two points. Take samples from process conditions with a wide span in the measurement range.
- Calculate field gain and field offset from the data points.
- Go to Menu > Concentration curves.
- Select the concentration curve and Modify adjustment.
-
Modify the values to Offset and Gain.
If there is already a previous field calibration, before calculating the offset and gain values for a new field calibration, reset the values as follows: - Offset: 0
- Gain: 1
