6.7 Important Operating Parameters
If a parameter listed below is not available in the Chromeleon software,
consider updating the firmware and Chromeleon version.
TIP The Instrument Method Wizard provides different parameter view
modes. Depending on the parameters to be set, you can select the
desired view mode (for example,
Easy or Advanced ).
For more information, refer to Chromeleon Help and documents .
Parameters Description
Data collection rate Sets the number of data points per second (Hz) that the
Chromeleon software collects from the detector and
stores as raw data. The maximum data collection rate
depends on the detector type and the software version.
For more information on how to set the data collection
rate, see
Data Collection Rate ( } page 92) .
Lamphouse
temperature The temperature signal channel ( Lamphouse
Temperature ) that is available in the Properties dialog
box of the detector, can be used for troubleshooting
purposes.
The lamps of the detector are very sensitive to changes in
temperature. In case of baseline drift problems, the lamp-
house temperature signal can help to find the reason for
the problem.
Select the signal channel to record the temperature.
Chromeleon generates the appropriate channel for
recording the temperature of the detector lamp house.
Leak detection Leak detection is enabled as a standard when the
detector is shipped (
Leak Sensor Mode = Enabled ). This is
the preferred setting.
Peak width The peak width is a supporting parameter for the data
collection rate setting and the response time.
For details on the peak width and selecting it individually,
see
Response Time and Peak Width (

page 92) .
Response time The response time determines how quickly the detector
responds to a change in signal.
For details on the response time and selecting it
individually, see
Response Time and Peak Width
