Handling
The VarioCAM
®
hr head is equipped with a highly sensitive uncooled microbolometer detector. Object
radiation occurring in thermographic practice does not cause any changes in the detector. However,
black-body radiation overdrive exceeding 1,000 °C in measuring ranges 1 and 2 or 2,000 °C in
measuring ranges 3 and 4, may result in irreversible damage and must therefore be avoided by
selecting a suitable calibration range* prior to measuring.
The VarioCAM
®
hr head must, neither in operation nor when switched off, directly be focused into the
sun or other sources of intensive radiation (e.g. lasers), since this may result in changes of the
microbolometer detector, whose origin can unambiguously be proven. The manufacturer waives any
warranty for such damage.
It is also imperative to avoid indirectly capturing any sunlight or other highly energetic radiation via
reflective surfaces directed into the field of view of the VarioCAM
®
hr head!
Under certain conditions, it cannot be excluded, even when the system is switched off, that the
detector may be damaged when directed into sunlight. Therefore, when the VarioCAM
®
hr head is not
in use, the lens must be capped with the protective cover included.
Only use SecureDigital cards in the SD slot of the VarioCAM
®
hr head. Otherwise damage to the
camera or the memory card can arise, for which no liability will be accepted.
Lens changes should not be carried out in rooms of high dust load or humidity, since IP 54 protection
class is not guaranteed with the lens removed.
