How can faulty calibration be resolved?
Faulty calibration can only be resolved by a precise re-calibration. Where the conditions for
precise calibration are lacking, this can be mitigated by a reset to factory settings. This function
gives the user the option to reset the sensors to their initial position, however, this will not
correspond to the current behaviour status of the sensors.
Open the
sub-menu “Calibration”
with
[MENU]
and press
[OK].
The relevant temperature value can be calibrated on the sensors for oxygen and pH. Please bear
in mind that the normal comparative value used must have a very high quality of <0.1 °C, and
the sensor must be exposed to a very constant temperature for 10 minutes. To avoid extreme
changes, the temperature range can only be changed by ± 1°C.
