3 Laser safety instructions
Class 2 Laser Product
• Never look directly into the laser beam path
(emitted power <1.0 mW at a wavelength of 630-670 nm)
• Do not leave the instrument unattended when the laser is activated.
• 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 surfaces.
• All currently valid laser safety standards must be observed.
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 opening).
4 Selecting an installation location
When choosing the installation location and during the pyrometer alignment, it is imperative to
ensure that only the free pouring stream is within the field of view.
When the background is hotter than the object focused on or when the measurement is made
through the inoculant, the accuracy of measurement will be influenced.
The pyrometer should be oriented as far as possible at right angles to the pouring stream. Ide-
ally, the pyrometer should be mounted so that it is aligned with the back of the pouring stream.
