Adjusting the required measuring distance
The required measuring distance must be adjusted to achieve the spot size mentioned in the
tables above. This can be done between the smallest and the biggest limit value.
Note: The measuring object has to be bigger than or at least as big as the spot size
of the pyrometer.
To release the optics, turn it counterclockwise. Then it
can be pushed or pulled to find the correct measuring
distance. To fix the optics, turn the optics clockwise.
Adjusting the measuring distance with help of
the table:
The table mentions the minimum and maximum
measuring distance for each of the three focusable
optics. This corresponds to the longest or the shortest
objective length. As an example, a further value
between max. and min. is shown. The objective length
“S” can be measured with a caliper.

The following methods can be used for measuring distances:
Adjusting the measuring distance with help of the thru-lens view finder:
The focusable optics is correctly adjusted to the required distance, if the measuring object is
shown as a sharp image in the view finder. A circle marks the position of the measuring spot.
Adjusting the measuring distance with help of the laser targeting light:
On the focused measuring distance the laser has its smallest spot size and is illustrated exactly.
