Excessive Readout Noise

Excessive readout noise with the intensifier off indicates possible moisture accumulation
in the CCD. This should be corrected promptly or permanent damage not covered by the
Warranty could occur.
Normal camera noise is a function of the gain setting and temperature as well as CCD
type, but is typically in the range of 1-50 ADU rms (6 -300 ADU pk-pk). This is on top
of offset that typically is about 600 counts. Moisture accumulation produces a coarser
noise with many spikes  300 ADU. If these types of spikes occur, especially after the
camera has been in use for an extended period, turn off the system immediately. Have the
unit serviced by Princeton Instruments or an authorized service facility of Princeton
Instruments.
