Performing an Autoreagent Calibration
If you use the Autoreagent function, you should perform an Autoreagent Calibration after you have
performed annual maintenance on the Analyzer, including a sample flow rate calibration
(page 141), Analyzer calibration (page 146), and calibration verification (page 149). You must first
perform a multi-point calibration before performing the autoreagent calibration. The autoreagent
function should not be used in applications where samples are expected to be less than 1ppm.
When you are ready to perform the Autoreagent calibration, follow the steps described in
“Preparing for Calibration” on page 139 and then follow this procedure:
1. If the Analyzer is taking measurements, press the Stop Analysis button.
2. If you have an ICR unit, make sure the lever is in the Bypass position.
3. Press the Menu button, select the Maintenance tab, and then press the Calibrate button.
4. Press the Autoreagent Cal button.
5. Remove the protective cap from the standards vials, and avoid touching the septa to
protect against introducing foreign particles.
At this point, the prompts on the Analyzer's display screen will help guide you through the
Autoreagent calibration process.
6. Insert the Reagent Water into the IOS System, and press Next.
