4. Temperature
By entering the water temperature, the indicated conductivity value can be
compensated to allow for the current temperature.
The conductivity measurement is based on a water temperature of 25 °C. In case of a
higher or lower temperature, this can be compensated by hand.
5. Compensation correction factor
Other measuring errors, which may arise through valorisation or cable capacities, for
example, can be compensated here by entering a correction factor, varying from 0.10
to 5.0.
Take a water sample and measure the conductivity using an accurate conductivity
meter: this results in the calibration value. Record the controller reading as the
measurement value.
Use the formula below to calculate the correction factor:
