the last time this type of spectrum was acquired. Recent entries for each spectrum type are available by
tapping the down arrow on the right side of the field, or a new label can be entered by tapping the
Edit
button.
3.
Enter a preset count time for this acquisition, in seconds, in the
Next time preset
field, or leave the field
blank or enter a zero (0) if it is intended to manually stop data collection. Note that the
Identify preset
count time on the Analysis Settings page is ignored when in multiple-spectrum ID Mode.
The field is initially populated with the time used the last time this type of spectrum was acquired. Recent
entries for each spectrum type are available by tapping the down arrow on the right side of the field, or
a new label can be entered by tapping the
Edit
button.
4.
The user is now ready to acquire the spectrum. Position the source (or blank), remove all other nearby
sources, then tap the lower-right
Collect [spectrum type] Sample
button (the button label will depend
on the spectrum type selected). The ID Mode screen (Figure 37) will be displayed. Wait for the count
preset to elapse or tap
End Now
to manually stop data acquisition. Note that
Quick Save
is not available
when performing a
Multiple Spectrum ID Mode
acquisition.
5.
When spectrum acquisition is complete, the screen will switch to the Multi ID Mode screen (Figure 63)
and wait for information to be entered for the next spectrum. The bottom-left
Spectra
counter will track
the number of spectra that has been added to the file so far; and the
Back
button will change to
Finalize
.
6.
Each time a spectrum is acquired on a blank sample, its spectrum is saved internally. The operator can
then tap
Last Blank
to add it to the current N42.42 file, or to any subsequent file until the next blank
spectrum is acquired. Known spectra are handled the same way, and the operator can tap
Last Known
to add the most recent known spectrum to the current file or to any subsequent file until the next known
spectrum is collected. This feature saves the time of unnecessarily repeating blank and known
measurements.
7.
After all spectra have been added to the file, tap
Finalize
. This will navigate to the optional metadata
page shown in Figure 61, where additional information can be entered.
8.
To complete the multiple-spectrum measurement, tap the
Finish
button to return to Detect Mode.
4.8 MANUAL DATA FILE TRANSFER
The Detective X saves all data collected in ID Mode. Data files are saved in ANSI N42.42-2012 format. Files
will have a background spectrum and one or more measurement spectra. The filename format is:
XXXXXXX_YYYY_MM_DD_HH_MM_SSS
where the 7 Xs represent an ever-increasing counter, and the remaining string is the UTC date-time stamp.
The spectral file can be viewed with U.S. government-supplied software; MCA emulation software such as
Los Alamos National Laboratory’s PeakEasy or Sandia National Laboratory’s Cambio; or ORTEC’s
GammaVision® Gamma-Ray Spectrum Analysis and MCA Emulator application (A66-BW).
Data files can be accessed in several ways with Detective X. The manner in which the user will access these
files will depend upon the current destination directory, be it USB Flash Drive or “My Documents” folder, as
discussed in Section 4.4.2.
