Page 15: Small Focus W/Rh
Small tungsten focus Attach an 18 24 table. With the MAMMOMAT 3000 Modular switched off, make a connection between X813.9, board side, an D801 and +24 V. This will simulate the magnification table and small focus will be selected. To do this (see fig 3.4): 2.1 Unplug X813 on D801. - Page 16 Fig 3.4 Select W/Rh anode/filter combination. Check the light field/radiation field according to the Installation and Set-up Instructions for MAMMOMAT 3000 Modular. The beam limiting device must not run into its mechanical NOTICE endstop. If it does the value must be changed.
