Checks with a small focus and without AEC 6
Prerequisites
• Make sure the magnification table is mounted, so that a small focus is selected.
• Deselect D and H on the control console, the MAMMOMAT is in mAs mode without AEC.

• Cover the detector with the large steel plate or with a lead apron.
Test performance
1. Adjust the exposure value on the control console according to the table above.
2. Start an exposure.
3. Check and measure the kV value and the tube current characteristic on the
oscilloscope.
The accuracy of the kV is &5%, for tube current &10% and for the mAs product
&10%.
4. Record the measured kV and mAs value in the Startup Protocol, page 11 - 1.
5. Change the setting and continue with the next measurement until you have
completed all measurements from the table above.
The magnification table is only shipped with the system when the
customer had ordered this option.
