˃
Enter the value of the solution or the reference measurement.
˃
With OK you execute the calibration and reach the info screen, showing the results of the calibration.
˃
With the SAVE button you store the results. With DISCARD you reject the results and keep the
previous calibration values.
Note
If the TDS factor not between 0.01 and 2.00 (for higher measuring ranges
between 0.1 and 20.00) saving is not possible.

TDS calibration – reference
˃
Select the symbol RUN to start the calibration
˃
If you use a solution with known TDS take care that the sensor is free hanging and a least the
electrodes or for a metal sensor the complete shaft immerses. There should be no gas bubbles at
the electrodes and the probe should be complete mixed.
˃
I you use a reference measurement for calibration measure TDS at the same place where the
online measurement measures. If this is not possible take a representive sampel. Keep in mind to
use for both measurements the same compensation and reference temperature.
