If the amber LED on the back of the camera does not illuminate while images are 
being acquired and no images appear: 

•  Confirm that the green LED on the back of the camera is illuminated, 

indicating that the camera is powered on. See Green LED Does Not 
Illuminate (Camera Has No Power) on page 12. 

•  Confirm that the correct CoolSNAP camera is selected in your imaging 

software application.  

•  Power off the camera and the host computer and check all system 

connections (particularly both ends of the data cable). Restart. If the 
amber LED on the back of the camera does illuminate while images are 
being taken, but no images appear: 

•  Confirm that Windows is set for at least 16-bit colors. 
•  Confirm that the camera is operational by taking an image with a 

standard C-mount lens attached to your CoolSNAP. Using normal 
room lighting, place the camera on a table about 3 meters away 
from an object and acquire an image using your system’s Brightfield 
settings.  

If the problem persists, contact Photometrics Customer Service. 

 

If you notice bright spots (hot pixels) in the image or an increase in background 
noise, take another calibration image and then re-acquire the original image. 

  

It is normal for the camera to be slightly warm to the touch while in operation. 
However, if the camera is more than slightly warm to the touch (and at least 1/2 
inch of space has been left around the external cooling fins for air flow), switch 
off the camera immediately and contact Photometrics Customer Service. 

 

If a PVCAM error message appears, note the message’s number code and 
contact Photometrics Customer Service. 

 

If you notice lengthy pauses marked by a lot of disk activity while imaging: 

•  Close any other programs that may be running. 
•  Install more physical memory to your computer system.
