The instrument will read the electrodes for 10 seconds, displaying the output (as it counts
seconds):
Figure 16
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 electrode 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.
On the DataLogger, press 1 to continue with calibration. The DataLogger will read the electrodes
for 10 seconds, displaying the output. After 10 seconds, the instrument will display the final pH
reading and offer the options to 1) Accept pH 7 buffer readings; 2) Redo pH buffer 7 readings; or 3)
Exit pH electrode calibration. If the readings are satisfactory, log pH 7 reading and press 1; if the
readings are suspect, press 2 to return to pH 7 calibration step.
