4.7.3 Ending the ID Mode Measurement Manually or Automatically
Advanced operators can use the spectral display and top peaks list to guide them in choosing how long they
need to accumulate data in ID Mode. Optionally, a fixed counting time (a counting preset ) can be specified.
This is more practical in many instances because it removes time subjectivity in making measurements. Enter
the fixed counting preset on the Analysis Settings page (Figure 60), which is accessed from the Advanced
Setup page. The Identify preset field is blank by default, indicating no counting preset has been set (or the
preset can be disabled the preset by entering a value of zero [0] seconds). Tapping the Identify preset field
pops up a numeric keypad so the user can enter the desired count time.

4.7.3.1 Capturing Optional Metadata
The Detective X can generate a lot of data quickly. To help make sense of it later, it may be useful to capture
information about the spectrum being collecting at the time it is collected. For this reason, when the ID Mode
acquisition ends, the screen shown in Figure 61 opens to give the option of capturing several kinds of
information that will be saved along with the radiological data in the N42.42 file.
