(*3) Spectral Response: Positional relation between distance and sighting point This is a one-point laser sighting thermometer. The laser mark is sighted approximately 14 mm above the center of the spot. (When the distance is approximately 225 mm)  When the measurement distance is approximately 225 mm, the laser marker is output aiming at the point illustrated above. Refer to the figure as a guide. |
