3.10 Single Scan
A single scan can be done by pressing the "Scan" button in the main window. The
mar345−Scan window pops up. The directory, image root, image number and scan mode
can be selected. The output format always is "mar345". Press "Scan" to start the scan A
scan is always followed by an erase. Instead of a scan one can do an erase cycle. "Change
Mode" only drives the scanning head to the desired position.
3.11 Shutter Timer
The X−ray beam shutter can be operated manually, although normally there should not be
any requirement to do this. When operating the shutter manually it can be useful to know how
long time the shutter is open. When opening the mar345−Shutter Timer window (shortcut:
F4) the program starts counting how long time the shutter is open. One may enter a closing
time (in seconds). When this time period has elapsed, the shutter closes automatically.
