Note:
Depending on the ambient temperature and Cooler setpoint, the time to
reach the setpoint temperature can take as long as 15 minutes. Once the CCD
temperature has stabilized at the setpoint value, it is recommended to allow the
entire camera an additional 5 to 10 minutes to reach thermal equilibrium.
Note:
Best regulation is achieved when the power to the cooler is kept below
85%. This gives the camera some headroom to compensate for variations in the
ambient temperature. If the camera can not reach the desired temperature, it will
keep trying by running the cooler at 100% power indefinitely. If the desired
temperature hasn’t been reached within 15-20 minutes, or the power level is
above 85%, we recommend selecting a higher Setpoint temperature.
Caution:
Be careful not to block free air movement around the camera, or any
air flow through the fans and cooling fins on the rear of the camera.
