Makeup Temperature (only appears if the makeup conductivity sensor option card is installed)
All of the menus described above for the system temperature also apply to the makeup
temperature.

Current Reading/Perform Calibration
The current reading is a live reading of the calibrated pH of the sample.
To Calibrate the pH electrode click on the “Perform Calibration” button and a new window will
appear. Select either a 2-point calibration, a 1-point calibration or a 1-point process calibration by
clicking the appropriate button.
2 Point Calibration
First you will see a warning that pH control will be suspended during the calibration. Click on
“Continue” to start the calibration, or “Cancel” to abort the calibration.
If no temperature element is detected, then the controller will allow you to enter the buffer
temperature manually. Otherwise it will display the electrode temperature.
You then be prompted to “Please Rinse the Electrode”. Do so, then click “Continue”.
You will now be prompted to type in the value of the first buffer being used. Do so, then click
“Continue”.
You will now see the mV output from the electrode. When this value is stable, click “Continue”.
You then be prompted to “Please Rinse the Electrode”. Do so, then click “Continue”.
You will now be prompted to type in the value of the second buffer being used. Do so, then click
“Continue”.
You will now see the mV output from the electrode. When this value is stable, click “Continue”.
The WEBMASTER will either pass or fail the calibration, and prompt you to return the electrode
to the process. Click “Continue” when you are ready for pH control to resume.
If the calibration fails for any reason, refer to Section 8 for troubleshooting help.
1 Point Calibration
First you will see a warning that pH control will be suspended during the calibration. Click on
“Continue” to start the calibration, or “Cancel” to abort the calibration.
If no temperature element is detected, then the controller will allow you to enter the buffer
temperature manually. Otherwise it will display the electrode temperature.
You then be prompted to “Please Rinse the Electrode”. Do so, then click “Continue”.
