6. REPLAY — REVIEWING SAVED
SURVEY FILES
The Replay feature allows you to review the contents of survey files currently stored on the HX.
Use it to view the spectral contents of the survey (ICD1/ICD2) file pairs, the real time and live
time for each spectrum contained in each file pair, the radioactive sources identified (if any), and
the alarm types associated with each identification.
NOTE
See Section 2.4.1 for a detailed discussion of the types of spectra stored in ICD1 files.
The Replay mode’s user interface is similar to the PC-based HX Offline Analysis Program
included with the Micro-Detective-HX. If you are already familiar with the Offline Analysis
Program, you will most likely find the Replay controls intuitive. The histogram controls (e.g.,
Zoom In/Out, Pan Left/Right, Log/Lin, marker and marker information) are discussed on
page 28.
6.1. Overview

all “rolling window” spectra, any Long- or Fixed-Sample spectra, and the Survey’s
cumulative spectrum.
4) View the histogram ( ) for the spectrum currently highlighted in the upper Spectra
section of the screen, as well any “LEDs” for alarms that were generated during that
spectrum acquisition.
5) View any identifications ( ) recorded during acquisition of the highlighted spectrum.
6) Exit ( ) the Replay feature and return to the HX program’s Main Menu.
6.2. Startup
Navigate to the Main Menu and select Replay. This will open the Replay screen without any
survey data displayed. Figure 44 shows an overview of the major screen features/display modes.
