IMPORTANT
The above ranges for ambient temperature (
T
a
) only apply to free-standing
mounted detectors. If the detector is not free-standing, this can lead to an ad-
ditional increase in surface temperature (e.g. by reflection of heat). In this case,
the ambient temperature (
T
a
) must be accordingly reduced in order to make
sure that the maximum surface temperature is not exceeded.
