Calibration messages
Wrong Buffer
If the buffer is not recognized or the offset is out of the accepted
range, “Wrong Buffer“ message is displayed.
Change the buffer, clean the electrode and repeat calibration.
Wrong Standard
If the EC standard is not recognized “Wrong Standard“
message is displayed. Change the solution, clean the electrode
and repeat calibration.
Wrong Temperature
If the temperature sensor is reading an extreme value, the
"Wrong Temperature" message is displayed. Replace probe.
No buffer detected
This message appears if the probe has detected no buffer.
Invalid slope
This message appears when the calculated slope is not in the
acceptable range.
Clean electrode
This indicates poor pH electrode performance (offset out of
accepted window, or slope under the accepted lower limit).
Cleaning the probe will improve the pH electrode's response.
