Checking the Detective-EX’s calibration is easy, whether you have a docking station
with its built-in
137
Cs source; a PAC-II charger, which does not include a calibration
source; or are working in the field under battery power. The Detective-EX allows you to
choose the calibration source that best suits your needs — even the
40
K naturally present
in concrete or low-sodium salt substitute.
!
The Detective-EX includes global positioning (GPS) hardware, and where GPS signals
can be detected, the upper right corner of the screen includes the current latitude and
longitude, as shown in Fig. 14 on page 22. The GPS coordinates are captured and stored
at the start of each identification acquisition, saved as part of
.SPC
or
.N42
spectrum files,
and available as one of reports discussed in Section 5.1.6.2.
!
The Detective-EX is equipped with IEEE 802.11b wireless connectivity. Third-party
software can be used to implement wireless communication. See the Detective-EX
Wireless Remote Operation note, P/N 932735).
Before using the Detective-EX, it must be set up and cooled; and the calibration should be
checked according to the instructions in Chapter 2.8. The instrument is shipped fully calibrated
and is likely to still be correctly calibrated, but checking the calibration is considered good
practice.
1.3. How This Manual Is Organized
This release of the Detective-EX combines the “operator” and “administrator” functions into one
manual. Chapters 2 and 3 cover topics germane to everyday radiation monitoring tasks. The
remaining chapters are aimed more at administrator-level users and expert spectroscopists.
“Operator-oriented” chapters:
!
Chapter 1 — System features, spectrum storage, file formats, and filename conventions.
!
Chapter 2 — Unpacking, startup, operating limits, initial configuration, and user-
interface overview.
!
Chapter 3 — Using the Detective-EX to monitor and identify radiation sources.
!
Chapter 4 — Radionuclide library.
“Administrator-oriented” chapters:
!
Chapter 5 — Administrator-level setup features.
!
Chapter 6 — Transferring survey files to a computer.
!
Chapter 7 — Troubleshooting and error messages.
!
Chapter 8 — Using the Detective-EX with a computer and ORTEC spectroscopy
software.
