783620H / 1013 5. MENU COMMANDS
Sample Start/Stop Time
These dates/times are the start time of the sample collection and the stop time of the sample collection. For example, for air filters, the start time is the time when the air flow is started and the stop time is when the air flow is stopped. These times are used to calculate the build-up of the activity in the sample. It is assumed that the spectrum is not collected during the build-up time. The correction for the build-up is given in Section 5.8.4.
5.2.2. Start
Based on the Group Acquisitions setting in the
Acquisition Settings dialog, Start simultaneously begins acquisition in all displayed Detectors (All
MCBs) or one Detector at a time (Current MCB); or asks if you wish to begin data collection in one or all displayed Detectors (Prompt), as shown in
Fig. 75.

Detectors.
Any warnings arising from problems detected at the hardware level will appear in a message box or on the Supplemental Information Line at the bottom of the display. The Detector can also be started with the <Alt + 1> accelerator, the Start Acquisition button on the toolbar, or the Start command on the right-mouse-button menu. If the Detector is already started or if GammaVision is in buffer mode, this command is disabled.
See Section 5.2.1.2 for a discussion of how ask-on-start options can affect the start of data acquisition.
5.2.3. Start/Save/Report
This command performs all three functions without user intervention. The Start is the same as the Start above, Save is the same as File/Save (using the filename in the Acquire/Acquisition
Settings... dialog), and Report is the same as Analyze/Entire spectrum in memory. Based on the Group Acquisitions setting in the Acquisition Settings dialog, Start/Save/Report simultaneously begins acquisition in all displayed Detectors (All MCBs) or one Detector at a time
(Current MCB); or asks if you wish to begin data collection in one or all displayed Detectors
(Prompt).
5.2.4. Stop
Stop terminates data collection in the active Detector window. The Detector can also be stopped with the accelerator <Alt+ 2>, the Stop Acquisition button on the toolbar, and the Stop command on the right-mouse-button menu. Based on the Group Acquisitions setting in the Acquisition Settings dialog, Stop simultaneously halts acquisition in all displayed Detectors (All
