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).
Often, cleaning the probe will improve the pH electrode's
response.
