The second type of Keep Clean Cycle 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 congures a kinetics series acquisition, as well as dening the exposure time and the readout mode, they
also dene the number of scans to capture and the time between the scans. During the time between individual scans
the sensor must be kept free of charge to ensure the data captured is a true reection of the light that fell on it during
the exposure 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 Cycle is
completed with a sufcient number of vertical shifts to ensure both the Image and Storage areas are charge free.
