•
Multiple spot compensation may be required when doing multiple exposures on a single film. In this
mode of serial recording, the X-ray field is usually coned down to a small area. Due to the lack of scatter
and possible AEC field cutoff, an AEC density offset may be added if required. This offset is known as
multiple spot compensation.
•
In order to activate the multiple spot compensation feature, the R & F table must supply a closed dry
contact when the SFD is operated in multi-spot mode. The multi-spot input to the generator is at TB5
pins 11 and 12 on the room interface board.
