Figure 24: Reviewing TC and IC Values from a Single-Point Calibration
12. Remove the IC Calibration Standard from the IOS System.
13. You should now verify the calibration. Proceed to “Performing a Calibration Verification” on
page 149 for instructions.
Performing a Multi-Point Calibration
Before performing a multi-point calibration, save the current Analyzer system settings and evaluate
whether a TOC Autozero is required, as described under the section called “Preparing for
Calibration” on page 139.
When you are ready to calibrate the Analyzer, follow these steps:
1. If the Analyzer is taking measurements, press the Stop Analysis button.
2. If you have an ICR unit, place the lever into the Bypass position. If you leave the lever in the
Inline position, a warning message will display later.
3. Press the Menu button, select the Maintenance tab, and then press the Calibrate button.
4. Press the Multi Pt Cal button.
5. If you have not performed a reagent flush in the last 8 hours, you must perform one now.
Make sure the Analyzer is connected to a water supply and click Yes.
