SLOPE. In multigas mode, both versions are listed and should be checked
After completing one of the calibration procedures described above, it is important to
evaluate the analyzer's calibration slope and offset parameters. These values describe the
linear response curve of the analyzer. The values for these terms, both individually and
relative to each other, indicate the quality of the calibration. To perform this quality
evaluation, you will need to record the values of both test functions (Section 4.2.1 or
Appendix A-3), all of which are automatically stored in the DAS channel CALDAT for
data analysis, documentation and archival.
Make sure that these parameters are within the limits listed in Table 6-5.
