6. Wait for the TOC Autozero to complete before proceeding with the calibration.

Perform a Sample Flow Rate Calibration

Prior to calibrating the Analyzer, replace the pump tubing as part of the annual maintenance on the
Analyzer (see "Replacing the Sample Pump Tubing" on page 179). Then, perform a sample flow rate
calibration, as described in this section.
Before proceeding, make sure you have saved the current Analyzer system settings, as described in
"Export Current Constants" on page 139.
For the sample flow rate calibration, you will need the following items from the Analyzer's
accessories kit:
• 10-mL graduated cylinder
• 1/8" OD tubing with 1/8" Swagelok fitting for waste line, approximately 12" long
• Plug for IOS waste line
Perform the sample flow rate calibration as follows:
1. If the Analyzer is taking measurements, press the Stop Analysis button.
2. Press the Menu button, select the Maintenance tab and press the Calibrate button.
3. Press the Flow Rate Cal button.
4. Ensure the Analyzer is connected to a source of water and then press Next to continue.
5. The Analyzer will then flush the acid and oxidizer out of the sample line.
6. When the flush is completed, the Analyzer will prompt guide you to attach the 12" waste
line (from the Analyzer's accessories kit).
To install the 12" waste line, your must first disconnect the 7/16" nut that connects to the
port labeled Waste on the side of the Analyzer and gently pull the tubing aside; attach the
rubber plug to this tubing. Attach the 12" waste line by securing the fitting with a 7/16"
open-end wrench.
When the 12" waste line is installed, press Next to continue.
7. The Analyzer will fill the waste line with sample water.
8. When the waste line is filled, the Analyzer will instruct you to insert the end of the waste
line in the 10-mL graduated cylinder. Do so, and then press Next to continue.
