1.7.6.4 - Dew Point graph
The Dew Point graph below plots the relationship between Relative Humidity and Dew Point at varying ambient
temperature. This can be used to calculate the minimum temperature the cooling water should be set to.
Figure 9: Dew point graph
For example, using a DZ model you will need 10ºC cooling water to guarantee performance down to -100ºC. In
the relatively dry atmosphere of an air-conditioned lab, cooling water at 10º should not present any problems.
However, in humid conditions (such as exist in some parts of the world) condensation may occur, resulting in
damage to the head. In such conditions you will have to use warmer water (20ºC or even higher if it is very
humid). The minimum CCD temperature in this example would then be limited to between -90ºC to -95ºC.
1.7.6.5 - Fan settings
The speed of the cooling fan can also be controlled. Select Fan Control from the Hardware drop-down menu
as shown:
The Fan speed dialog box will appear:
Select the speed you require as necessary (this may affect the cooling ability of the CCD).
NOTES:
1.
After changing from High to Low, it may be necessary for the camera temperature to stabilize
b
efore acquiring data. However for optimum performance it is recommended to leave the fan
setting at High.
2. When using water cooling, the internal fan of the camera may be switched off via the software
provided the water source is capable of preventing the camera from overheating.
