Taking TOC Measurements

After you have set the analysis mode and have configured the mode settings (as described in "Setting the

button to begin.

The Menu screen provides you with access to all Analyzer settings and configuration options. Note that if

number of rejects.
• Data — Display and export historical data stored in RAM.
• I/O — Configure the input and output of data from the Analyzer.
• Maintenance — Display information about the Analyzer's consumables levels, system information, and
error messages. Also perform calibration and system suitability operations.

From any tab under the Menu screen, you can press the Start Analysis button to initiate TOC measurements.
