If the label on the Conductivity Standard shows a different value, press Edit , enter the value, press
Enter , and then press Next to continue.
When prompted by the Analyzer, remove the first four vials and insert the next four vials into the
Super
iOS System vial ports in the following order:
Port 1 = empty
Port 2 = TOC Calibration Blank
Port 3 = TOC Calibration Standard (1.0 ppm KHP)
Port 4 = TOC Calibration Standard (500 ppb KHP)
Press the Next button. Proceed to Step 12.
9. If you have a standard iOS System:
• Open the door to the iOS System and wait 30 seconds for water to drain.
• Insert the first TOC Calibration Blank into the iOS System and press Next .
• When prompted, remove the TOC Calibration Blank from the iOS System, insert the second TOC
Calibration Blank, and press Next .
• When prompted, remove the TOC Calibration Blank from the iOS System, insert the TOC Calibration
Standard (1.50 ppm KHP), and press Next .
• When prompted, remove the TOC Calibration Standard (1.50 ppm KHP) from the iOS System.
Confirm the value of the Conductivity Standard and insert the vial into the iOS System. If the label
shows a value of 25 µS/cm HCl, press Next to continue. If the label shows a different value, press
Edit , enter the value, press Enter , and then press Next . If your configuration does not measure
conductivity, you will not be prompted to enter a conductivity value and you can skip this step.
• When prompted, remove the Conductivity Standard from the iOS System, insert the third TOC
Calibration Blank, and press Next .
• When prompted, remove the TOC Calibration Blank from the iOS System, insert the TOC Calibration
Standard (1.0 ppm KHP), and press Next .
• When prompted, remove the TOC Calibration Standard (1.0 ppm KHP) from the iOS System, insert
the TOC Calibration Standard (500 ppb KHP), and press Next .
10. After the last standard has been analyzed, the Calibration Summary screen is displayed. Part 1 of the
summary screen displays the data for the first two blanks and the 1.50 ppm standard (see Figure 26).
Press the
Next button.
11. Part 2 of the summary displays the data for the conductivity standard (see Figure 27). Press the Next
button.
12. Part 3 of the summary displays data for the blank, 1.0 ppm standard, and 500 ppb standard (see
Figure 27).
13. Press the Print button if you want to print the Calibration results.
