What is the calibration procedure for the device?

To access the calibration function group, press the CAL key. Calibration can be performed in several ways: by measuring in two calibration solutions with known pH; by entering data for slope and zero point; or, in the case of redox potential measurement, by entering the mV value or two different % values.

How can calibration be performed for the device's sensor, and what are the important notes regarding this process?

Calibration can be performed in several ways: by measuring in two calibration solutions with known pH, by entering data for the slope and zero point, or, for redox potential measurement, by entering the mV value or two different percentage values.

It is important to note that calibration is essential during initial startup (except for sensors with Memosens functionality) to ensure the measurement system provides accurate data. If calibration is interrupted (by simultaneously pressing the PLUS and MINUS keys to return to C19, C25, or C36) or if it is erroneous, the initial calibration values will be used. A calibration error is indicated by “ERR” and the flashing of the sensor symbol on the display.
