Warm-Up Phase
Warm-Up Phase
The warm-up time is approx. 2 to 4 hours.
The warm-up phase can take longer if the analyzer system was not brought to room
temperature before the power supply was activated.
During the warm-up phase measurement values can be outside the ranges specified in
the data sheet.
End of the
Warm-Up Phase
The warm-up phase is over when the temperature and flow status messages are gone
and the measured value drift is acceptable. The latter depends on the size of the
measurement range.
Readiness,
Sample Gas Supply
At the end of the warm-up phase the analyzer system is ready for operation and
automatically activates the sample gas supply.
Calibration
Calibration should only be started after the warm-up phase (see “Analyzer System
Calibration” chapter, page 80).
