Exploranium GR-135 - Analysis Menu; Store Spectrum; Start Meas

SAIC Exploranium – GR-135 System Manual page: 22
7.2 ANALYSIS MENU
When Nuclide ID is complete, ENTER goes to the main ANALYSIS menu
(Fig. 12) where further functions can be selected

7.3 STORE SPECTRUM
This option stores the current (most recently measured) spectrum in
the memory of the GR-135, assigns it a unique Sample Number and
tags it with the date and time of measurement for easy
identification. All data recorded in memory can be downloaded to
an external computer.
To store data in memory, highlight STORE SPECTRUM and
ENTER. A new display appears for 10 seconds as shown in fig.
13 – in this case showing that this spectrum has been stored as
Spectrum #12.
Fig. 13
Note that the GR-135 can store up to 187 complete 1024 channel spectra in memory.
7.4 START MEAS
This option allows the user to take another spectrum sample
without having to go back to the Main Menu and selecting
IDENTIFY again. If this option is selected then the IDENTIFY
sampling display (shown in 7.1 above) is shown and data
accumulation begins again. As the sample progresses the display
is updated at a 1/sec rate as shown in Fig. 14 until the preset
sample time is reached.
NOTE: If the IDENTIFY analysis capability is started from the
START MEASUREMENT menu item then at the end of the sample
the display goes to the ANALYSIS menu so the user can select
subsequent actions. However if IDENTIFY is started from the Fig. 14
MAIN MENU it automatically carries out NUCLIDE ID to try to somewhat
simplify user actions.
Labels are:
Sp1 – the last spectrum # that was stored. So if the current sample (when complete) is stored – it
would be Spectrum #2
RANGE 0-3072keV shows that the full 3MeV spectrum is displayed
MEAS – means that the system is in measurement mode
