As can be seen above, there is a CCD temperature monitoring window at the right hand side of the
panel. At switch-on, this will default to full power cooling with an end point of -40C (actual chip
temperature) and, needless to say, this is rather extreme. I recommend changing the set point to about -
10C for normal use, but you can go much colder if you are imaging during the winter months. Under
indoor conditions, the low airflow will limit the cooling capability, and you should use a set point of no
lower than -5C for stable cooling. You can determine the optimum settings for your camera and
ambient conditions when you have some experience of using the system, but do not try to operate at
extreme cooling when the air temperature is high. Connecting and using the external fan unit will
improve the cooling by at least -5C and can give as much as -10C extra delta T. It is connected by
using the 'Y' lead provided in the camera component set, as below:
