-40°C for air-cooled or liquid-cooled PIXIS-XF:1024.
The temperature should drop steadily, typically reaching the programmed
temperature in about 15 minutes. When the array temperature reaches the
programmed temperature, the Detector Temperature dialog will report that the
temperature is LOCKED. Note that some overshoot may occur. This could cause
temperature lock to be briefly lost and then quickly re-established. If you are
reading the actual temperature reported by the application software, there may
be a small difference between the programmed and reported temperature
when lock is established. This is normal and does not indicate a system
malfunction.
Once lock is established, the temperature will be stable to within ±0.05°C.
NOTE:
The Detector Temperature dialog will not display
temperature information while you are acquiring data.

5. Select Focus from the Acquisition menu to view successive images on the monitor
as quickly as they are acquired. Since no X-ray source is being used, the acquired
images will be of the camera's dark charge. As the CCD temperature decreases, the
image will get darker as the dark charge decreases. Signal changes may be more
easily seen on the cross-section views. When you stop the acquisition, you will be
given the opportunity to save the last displayed image.
