3. Press the Measure button to specify which value to measure: IC, NPOC, TOC, or TC.

set to On or Off.
5. If Check Standard is disabled, press the Check Standard button and then press the Enabled button that
appears to the right.

NOTE:
The number of rejects must be less than the number of repetitions selected for the check standard.
Rejects applies to the initial measurements of the check standard, (as shown in
Figure 41 Continuous Operationn page 127. Use this feature to exclude initial measurements when
the concentration of the check standard is different from the previously measured sample, so that
the average of the check standard measurements is accurate.
