Performing an Autoreagent Verification
Use the Autoreagent verification to confirm the Analyzer's current Autoreagent calibration is
accurate. GE Analytical Instruments recommends performing the Autoreagents verification after
replacement of pump tubing and after Autoreagent calibration.
The sample flow rate calibration (see page 141) should always be performed after replacement of
the pump tubing and before the Autoreagents verification.
To perform the Autoreagent calibration verification, 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 Ver 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 verification process.
6. Insert the Reagent Water into the IOS System, and press Next .
