6-1. Positional Relation Between Distance and Sighting Point
This is a one-point laser-sighting thermometer. The laser mark is sighted approximately 14 mm
below the center of the spot.
Example: When the distance is approximately 280 mm
Measurement spot (circle of diameter 28 mm)
Laser marker sighting point
When the measurement distance is approximately 280 mm, the laser marker is output aiming at the
point illustrated above. Refer to the figure as a guide.
Do not look into the laser marker or point it at anybody's eyes. Doing so may damage
your eyes.
Keep the unit out of reach of children.
Standard for Safe Use of Laser Products (JIS C6802): "Class II" is defined as follows
:
A visible light (of wavelengths in the visible region: 400 nm through 700 nm) with an output level
(approx. 1 mW or less) that is normally regarded harmless with respect to humans' physical defense
capabilities.
7. Maintenance
The accuracy of measurement is affected by dust or dirt on the surface of the infrared lens. Prevent
dirt or dust from adhering to the surface of the lens during use or storage.
When removing dirt from the infrared lens, use a blower for camera lenses. If stubborn stains persist,
clean the surface of the lens softly with a swab moistened with lens cleaning liquid.
NB: Never clean the infrared lens with water or detergent. Doing so may affect the performance of
the lens and cause inaccurate measurements.
