<8. VALIDATION AND CALIBRATION>
8 .1 Off-Line Manual/Automatic Checking and Off-Line Calibration
To perform either “Offline Calibrations” or “Offline Validations”, the Launch unit and Detect unit need to be
removed from their respective process interface and connected to an Off-Line Calibration Cell. If the analyzer is
installed on an extractive flow cell (enhanced flow cell or low volume flow cell) then it is already capable of being
validated/calibrated in off-line mode.
Before removing the units from the process, ensure that the process gas and window purge gas are correctly
isolated to prevent excessive pressure (process or purge gas) from being released or from over-pressuring the
analyzer.
AVOID SHOCK AND IMPACT TO THE ANALYZER
PERMANENT LASER DAMAGE MAY OCCUR
Please note that you can select the block mA value for automatic
