6.4 Safety instructions and precautions
The user must be familiar with following safety instructions.
Laser Radiation Hazard
Laser radiation can be harmful to eye!
PA pyrometer operates with a class 2 red light laser. Direct prolonged
viewing of a laser beam can injure the retina. Therefore, the following
safety precautions must be strictly observed, otherwise the laser may not
be operated!
Only use the laser to align and focus the pyrometer. Deactive the
laser immediately afterwards. Alternatively, the laser will automat-
ically switch off after 1- 15 minutes.
Never look directly into the laser beam path.
Do not leave the instrument unattended when the laser is activat-
ed.
Do not point the laser beam at any person.
During pyrometer installation and alignment, make sure to avoid
the possibility of laser light reflections caused by reflective surfac-
es.
All currently valid laser safety standards must be observed.
Laser Power
The laser operates at a wavelength of 630 - 670 nm (visible red light).
The emitted power of the laser beam at the lens opening is max. 1.0
mW. Under normal operating conditions, the emitted
radiation does not present a danger to human skin. This laser product is
classified according to laser class 2, IEC60825-1.
Laser Warning Label
The black and yellow laser warning label is affixed next to nameplate of
the instrument. An arrow indicates the laser emission path (lens ope-
ning).
