Handling
The VarioCAM
®
hr 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 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!
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 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. Otherwise damage to the camera o
the memory card can arise, for which no liability will be accepted.
For charging the included rechargeable Li-ion batteries, principally use the included recharger. The
recharger is only suitable for indoor use. In order to prevent fire hazards or electrical shock, the
recharger must not be exposed to either rain or moisture.
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.
VarioCAM
hr has a laser pointer* at its front, which emits a visual laser beam. Avoid directly viewing
into the laser beam and do not point it at any other person. The human eye can be harmed.
When firmly installing the thermographic system on equipment or in plants, care must be taken to not
allow the laser beam to run at eye level.
