4. Sensor Head Calibration
14) Accuracy Verification
It is always a good idea to verify that the calibration was
effective. If you wish to do this, go to the measurement
menu and make a measurement on the calibration plate.
The measured conductance should be close to 240 mmol
-2 -1
m s . Please note that the first 2-3 measurements after the
sensors have not been used for a while will be significantly
low due to sensor dehydration, and that the first two mea-
surements after re-wetting the filter paper will also be inac-
curate due to thermal disequilibrium.
