Automatic calibration:
The buffer solution value appears on the display. Insert the probe in the bottle and press the
key. A 60
second countdown necessary to complete calibration will appear on the display. If the alignment quality is below
50%, an error message appears on the display and you should press
to exit calibration (the pump exits
automatically after 4 seconds). If the quality is above 50%, the value is shown on the display and you should press
the
key to complete the procedure.

Manual calibration:
The buffer solution value appears on the display. Insert the probe in the bottle and press the
key. The value
of 465 mV should now flash on the display. Insert the probe in your solution and use the
keys to display
the value of the solution in your possession, then confirm by pressing the
key and begin the calibration
procedure as before
