Calibration Failed
The analyzer has failed calibration.
1. Check that the reagents are of the correct type, connected
correctly (Reagent 1 to valve R1 etc.) and are within their shelf life.
If it is possible that the reagents have become contaminated
replace them.
2. Check that the calibration settings are correct.
3. Check for any restrictions or blockages in the analyzer tubing or
valve manifold.
4. Check that each reagent/sample is drawn into the measurement
head correctly with no air bubbles.
5. Check the optical cell for any scratches.
If the error still exists contact the local ABB representative.
