The identifier is factory pre-calibrated using a multi-nuclide source. The calibration can be updated using a only
small
137
Cs source. The instrument is usually supplied with an exempt-quantity
137
Cs source, with a nominal
activity of 1.0 µCi (37 kBq), built into the docking station source tower. If your unit was not supplied with a
137
Cs
source, you can use naturally occurring
40
K or else define other calibration sources, as described in Section 5.2.1.

This chapter covers the steps you will need to prepare the Detective-EX for use:
! Unpacking, setup, and hardware overview (Sections 2.1 through 2.6)
! Operating cautions (Section 2.7)
! Startup and cooldown (Section 2.8)
! User-interface basics (Section 2.9)

Note also that where the spectrum should not be viewed by the operator, the spectrum display
can be disabled (see Section 5.2.4.2).
2.1. Unpacking and Setup
When you receive the Detective-EX/DX-100T, the shipping box contains the following:

! The Detective-EX/DX-100T portable identifier and USB cable
! The User’s Manual (P/N 931040)
! Padded carrying strap
! Docking station or ac power adapter/charger with optional built-in
137
Cs source

! Disposable plastic instrument covers (P/N 932725)
! An automobile accessory adapter to power the docking station or PAC-II charger from a
12 V battery
! An automobile accessory adapter to power the trans-SPEC-DX-100 directly from a 12 V
battery
Any options will be packaged separately, and will include instructions for that option.
NOTE If your Detective-EX was shipped in a foam-lined box, instead of a high-impact
plastic case, be sure to keep the box and foam and use it for shipping the identifier.
