Choice of exposure
Both Siemens MAMMOMAT 1000 and
Siemens MAMMOMAT 3000 Nova are
equipped with automatic exposure control
(AEC).
Only the kV value is set manually. After
exposure, the mAs value obtained can
be read on the generator control panel.
If desired, both kV and mAs can also be
chosen manually. When the mAs button is
first activated, a value of 100 mAs is shown
on the display. Continue to press the mAs
button until the desired value is shown,
then make the exposure.
