2. Use the arrows ( or ) to select the measurement to be displayed

(TOC, IC or TC). Press ENTER. The Current display will change to
indicate the new display option and the program will prompt for
confirmation. Press ENTER to return to the OUTPUTS menu.

3. Press CLEAR twice to return to the SETUP menu.

Warning 42

The accuracy of the TOC measurement is reduced when the TOC/IC ratio is

≤

0.1; for improved accuracy, use the IC Removal Module to reduce the

concentration of IC in the sample. After each measurement, the analyzer will
calculate the TOC/IC ratio and if this value is less than or equal to 0.1, a
