TDS Calibration
The TDSscan20 tester allows 1 to 3 points calibration. We recommend
that you perform 3 points calibration or select a standard solution
closest to the sample TDS you are measuring. When the calibration
is completed, all new calibration values will automatically override
existing data.
Make sure that using the fresh standard solution during the calibration.
DO NOT reuse the standard solution after calibration, contaminants
in solution will affect the calibration and eventually the accuracy of
the measurement.
