Features & Functionality
The second type of keep clean is executed between individual scans in a kinetic series, and is relevant to Non-Frame
Transfer Mode combined with either Internal or Software Trigger. It is called the Internal Keep Clean Cycle. When the
user congures a kinetics series acquisition as well as dening the exposure time and the readout mode, they also dene
the number of scans to capture and the time between the scans. During the time between individual scans the sensor

period. The keep clean cycle run during this time is very similar to that described in the Idle Keep Clean Cycle on the
previous page in that the cycle is one vertical followed by a series of horizontals. In this mode however the number of
times the cycle is repeated is determined by the cycle time set by the user. The keep clean is completed with a sufcient
number of vertical shifts to ensure both the image and storage areas are charge free.
