Repeat for electrode 2’s ID and press 3 to confirm.
8.
The instrument will prompt for the electrodes to be inserted into pH buffer 4 solution; Slide pH 4
buffer solution container onto electrode holder. Press 1 to continue with calibration or 2 to exit.
9.
The instrument will read the electrodes for 10 seconds, displaying the output (as it counts
seconds):
10.
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, log pH 4 reading and press 1; if the readings are suspect, press
2 to return to step 8.
11.
After accepting the pH 4 buffer readings, the Instrument will prompt for the electrodes to be
inserted into pH 7 buffer solution.
12. Remove the pH 4 buffer solution container from the electrode holder.
13. Rinse the electrodes and electrode holder using the manual wash or handheld wand for at least
20 seconds.
