Chapter 5 Analysis

Caution: If ENTER is pressed to skip the purge cycle, a message is displayed citing the
need to completely fill the cell. If the purge cycle is skipped, an error flag, "P", appears
next to the displayed data. Any logged data is also flagged with a “P” for insufficient
purge. This indicates that the sample fill cycle has been overridden and that the cell may
not have been completely filled with sample. The first few displayed data points may be
lower than expected. However, after the application’s purge time has expired (typically
60 seconds), the analyzer should be displaying the concentration of the external sample
and the error flag is erased.
