compensation
2%/°C
Method 3: Existing matrix
Data corresponds to the following solution
Matrix temperature compensation (existing data)
*SERV 22
Method 4: Where present matrix data does not exist,
for example, when the temperature coefficient
is
not
constant
α you can create a user matrix.
Calibration in Air (Air Set)
(correct zero offset
due to leakage resistance)
Calibrate in actual
measured solution
User-defined matrix temperature compensation
*SERV 23-28
Method 2: For other temperature compensation coefficients
