- Take samples from the process liquid and take a field sample.
-
Repeat many enough times.
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 > Configure device.
- Select the concentration curve you want to modify.
-
Scroll to the end of the screen to modify the Field gain and Field offset.
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: - Field offset: 0
- Field gain: 1
