To end the Long Sample:
!
Acknowledge any alarms (this will allow the HX program to respond to the next command).
!
Press or tap N then select End Sample from the submenu. This will return you to the Detect
screen. The HX will resume collecting 1-second spectra and analyzing a rolling window of
the 8 most recent spectra for IDs and alarms. The data collected during the Long Sample will
be analyzed and displayed as part of the End Survey report (Section 5.5).
The list of identifications in the real-time ID area can extend to multiple pages. In such cases,
the report page is entitled Sample 1 of [x], Sample 2 of [x], etc., where x is the total number of
pages of the report (see Fig. 36). Press or tap the S button to cycle through the pages.
5.4. Fixed Sample Screen
This test mode is a subset of Long Sampling. It allows you to collect samples at fixed intervals
of 5, 10, 15, 20, 25, 30, 60, 120, or 300 seconds.
To enter Fixed Sample mode from the Detect screen:
!
Press or tap N then select Fixed Sample from the submenu. This will display the Count
Time screen shown in Fig. 38.
!
Navigate to the desired time interval and press or tap S. Figure 38 shows the selection of a
20-second interval. Sampling begins immediately, tracked by a progress bar (Fig. 39). If the
Spectrum view option is enabled as described on page 28, the S button allows you to toggle
between viewing and hiding the histogram (see page 28 for instructions on the histogram
viewing controls).
!
To end the sample early, acknowledge any alarms, then press or tap N to return immediately
to the Detect screen.
!
At the end of the measurement, you are returned to the Detect screen, and the survey
continues. From there, you can choose to perform another Fixed Sample or a Long Sample,
exit back to Survey mode, or end the survey.
