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).
