The instrument, which was already prepared for manual calibration fluid introduction (See Section 5.5) and has been optically balanced on zero fluid prepared from the user’s sample, is ready for calibration.
Recheck the following before fluid introduction:
1.Analyzer is in the Analyze mode.
2.Air blow down valves are turned off. (Manual Mode Required)
