Repeat for electrode 2’s ID and press 3 to confirm.
The instrument will prompt for the electrodes to be inserted into pH buffer 4 solution; Slide cup with
pH 4 buffer solution onto electrode holder. Press 1 to continue with calibration or 2 to exit. Tips:
Don’t overfill solution. Cup only needs enough solution to immerse electrode tip and face. Don’t
reuse solutions.

The instrument will read the electrodes for 10 seconds, displaying the output (as it counts
seconds):
Figure 11
After 10 seconds, the instrument will display the final pH reading and offer the options to 1) Accept
pH 4 buffer readings; 2) Redo pH 4 buffer readings; or 3) Exit pH electrode calibration. If the
readings are satisfactory, press 1; if the readings are suspect, press 2 to return to re-do pH 4.

After accepting the pH 4 buffer readings, the Instrument will prompt for the electrodes to be
inserted into pH 7 buffer solution. Remove the pH 4 buffer solution cup from the electrode
holder.Rinse the electrodes, electrode holder, and solution cup using the manual wash for at least
10 seconds. Slide the pH buffer 7 solution cup onto the electrode holder.
