Setting the tube-current reduction

12

In Mammomat, the tube-current reduction is factory-set to "ON", which means that the 
tube current is reduced to approx. 50 mA during the first 100 ms of the exposure. In this 
way, possible grid lines are avoided.

If the tube-current reduction is set to "OFF", grid lines may occur at short exposure times 
(< 100 ms).
