Cross-sensitivity alignment
When should a cross-
sensitivity alignment
be performed?
Perform a CS correction if a sample component is inadequately affected by another
component (>2% of sample component span).
If the interference components are to be measured with the same unit as the
sample component, perform an internal CS alignment.
For instance, CS corrections are required in the following applications:
Sample component N
2
O, interference component CO
2
All required CS corrections can be found in the "Rekonur" configuration program.
Accessories • PC with serial port
• Advance Optima - TCT test and calibration software
• Serial port connecting cable, item no. 0743091
• Test gases
• Flow measurement unit
Preparation • Establish electrical connections
• The analyzer should be installed at the site at which it is to be used and should
be protected against vibration
• Set the test gas flows between 30 and 60 l/h and maintain stable +/-5 l/h.
• Connect the PC to the analyzer module
• Start the calibration and test software
Test • Test all detectors (the measured values should appear and be regularly
updated)
• Status message 0 for all detectors
