3. How to protect the cooler in QHY16803A?
The cooler in QHY16803A can lower the CCD temperature to a value that's almost 40 degrees
centigrade below the ambient temperature. So you need to be careful to avoid thermal shock,
which refers to when the cooler's temperature rises or fall dramatically, the cooler is subjected
to strong internal stress due to contraction principle. Drastic thermal shock can shorten cooler's
service life or permanently break it.
So when you begin to adjust the CCD temperature, you should avoid setting "Cooler Power" to
its maximum value, and you should gradually turn up the "Cooler Power" value. When you turn
off the power, if the "Cooler Power" value is very big, you should gradually turn it down before
