destination data drive (i.e., “...\<USB Flash>\Data2\”, “...\<USB Flash>\Data3\”, “...\My Documents\Data2\”,
etc.). Setting this field to zero (0) disables automatic archival. When set to zero, no automatic archival is
performed and the number of files in the Data folder will grow without bounds. Note that file interactions on
the device may slow considerably when the number of files in the destination folder rises above 500.
This screen also allows the user to define how the “Quick Save” functionality behaves. If the “Show Spectrum
File Details Dialog for Quick Save” option is enabled, then the user will be prompted to enter the metadata
(i.e., Location, Item Description, Conditions) as shown in Figure 61, that will be saved along with the
radiological data in the Quick Save N42.42 file. Any information here will be retained as the default
information displayed when the complete survey is ended.
4.4.3 Exiting and Restarting the Detective X Application
Tapping Exit App, from the Advanced Setup screen, navigates to the orange Launcher screen, which is
discussed in Chapter 3. From the Launcher, the user can run other ORTEC applications installed on the
Detective X’s computer. Other available applications are the Mobile MCB Server and the Sleuth application.
See Chapter 5 for details on the simplified, user-friendly Sleuth application. See Chapter 6 for details on using
the Mobile MCB Server and accessing the Detective X’s laboratory spectrometer functionality. To return the
instrument to its standalone identifier functionality, tap the Detective X button on the Launcher screen (see
Figure 27).
4.5 ALARM CONDITIONS
The conditions that can cause the Detective X to alarm are listed here in order of priority, highest to lowest:
Personnel Hazard
System Errors
Overrange
Nuclide Identified
Alarms are indicated by messages posted to the display. By default, they are accompanied by characteristic,
short-duration audio alerts and vibration of the instrument’s handle. When the Bluetooth headset is used,
the audio is routed there; the audio is rerouted to the Detective X when the headset is powered down.
By default, alarm messages are displayed as long as the alarm condition exists and are removed when the
condition no longer exist. For example, bringing a source anywhere near the instrument while in Detect Mode
will likely result in a “Nuclide Identified” alarm. The Detective X will display the nuclide ID, provide a short
audio alarm, and the handle will vibrate for a moment. The nuclide ID will continue to be displayed for as
long as it is detected. When the source is removed from the area, the nuclide ID will be removed from the
screen.
4.5.1 Require Alarms to be Acknowledged?
The user can choose whether or not to require all alarms be acknowledged. If the Require acknowledge
option is enabled, alarms will be latched, and an Acknowledge button, color-coded according to the nuclide
ID threat level, will be displayed at the bottom of the Detect Mode and ID Mode screens. Alarms will be
presented for acknowledgment, one at a time in order of alarm priority. The alarm message will not disappear
until the user taps the Acknowledge button. In addition, audio and vibratory indications will persist until the
alarm is acknowledged.
