4.7.1 Default Parameters
The versatility of this analyzer usually results in significant changes
being made to parameters over the course of time to better suit a
particular application. Occasionally processes change requiring
alteration to alarms, filter settings etc. At some time, it may be
beneficial to reset the analyzer to the default conditions as it was when
shipped from the factory. Below is a listing of the default parameters
used in configuring the typical GC-Pro FID instrument. Your specific
application may require different settings. Refer to the Addendum and
Testing Results section of Appendix C for any specific changes or

information regarding the current measurement state. The HOME screen

The Group name/tag is listed on the left most column and the
concentration for groups are displayed in PPB, PPM or % depending on
