.10 Single Scan

A single scan can be done by pressing the "Scan" button in the main window. Th

ar345−Scan window pops up. The directory, image root, image number and scan mod

can be selected. The output format always is "mar345". Press "Scan" to start the scan

scan is always followed by an erase. Instead of a scan one can do an erase cycle. "Chang

Mode" only drives the scanning head to the desired position.

.11 Shutter Timer

The X−ray beam shutter can be operated manually, although normally there should not b

any requirement to do this. When operating the shutter manually it can be useful to know ho

long time the shutter is open. When opening the mar345−Shutter Timer window (shortcu

4) the program starts counting how long time the shutter is open. One may enter a closin

time (in seconds). When this time period has elapsed, the shutter closes automatically.
