MESSAGES FROM THE PUMP
Rev 1.0
THIS MESSAGE MEANS THAT THE CALIBRATION IS IMPOSSIBLE AND HAS TO BE
DONE AGAIN.
If after the calibration repetition the display shows again this message:
a) Check that the buffer solution is not polluted (eventually replace it).
b) Check that the buffer solution selected on the display during the calibration is the value
of the one really used.
c) The pH probe could not be working well (replace it)
