GAA330-M EMISSION MONITORING SYSTEM
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.
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.
At the end of the warm-up phase the analyzer system is ready for operation
and automatically activates the sample gas supply.
Calibration should only be started after the warm-up phase.
