1 General Notes
1.1 Intended use
The optris PI calculates the surface temperature based on the emitted infrared energy of objects
[►6 Basics of Infrared Thermometry]. The two-dimensional detector (FPA - focal plain array) allows a
measurement of an area and will be shown as thermal image using standardized palettes. The
radiometric processing of the picture data enables the user to do a comfortable detailed analysis with
the software PI Connect.
The PI is a precise instrument and contains a sensitive infrared detector and a high-
quality lens. The alignment of the camera to intensive energy sources (high po we r
laser or reflections of such equipment, e.g.) can have effect on the accuracy of the
measurement or can cause an irreparable defect of the infrared detector.

• Avoid abrupt changes of the ambient temperature.
• Avoid static electricity, arc welders, and induction heaters. Keep away from very
strong EMF (electromagnetic fields).
• In case of problems or questions which may arise when you use the infrared
camera, please contact our service department.
► All accessories can be ordered according to the referred part numbers in
Read the manual carefully before the initial start-up. The producer reserves the right to
change the herein described specifications in case of technical advance of the product.

1.2 Warranty
Each single product passes through a quality process. Nevertheless, if failures occur contact the
customer service at once. The warranty period covers 24 months starting on the delivery date. After the
warranty is expired the manufacturer guarantees additional 6 months warranty for all repaired or
substituted product component s. Warranty does not apply to damages, which result from misuse or
neglect. The warranty also expires if you open the product. The manufacturer is not liable for
consequential damage or in case of a non-intended use of the product.
If a failure occurs during the warranty period the product will be replaced, calibrated or repaired without
further charges. The freight costs will be paid by the sender. The manufacturer reserves the right to
exchange components of the product instead of repairing it. If the failure results from misuse or neglect
the user has to pay for the repair. In that case you may ask for a cost estimate beforehand.

2.4 Optical specification s
Figure 2: PI 200 with visual camera
Make sure that the focus of thermal channel and visual channel (PI200/ 230 only) is
adjusted correctly. For focusing the thermal camera turn the lens in right direction for
“close” and to the left for “infinite” (
Figure 2), as well as focusing the visual camera with
the focusing tool supplied in the scope of delivery (Figure 3).
![](/html/4f/4f8c/4f8ceed226a6e5312157d0686f4aa5a28a6f75774d1772c249f5183cde3e8d04/bg16.png)
Figure 3: Focusing tool for VIS camera
The variety of different lenses offers the possibility to precisely measure objects in different distances. We
offer lenses for close, standard distances and large distances. Different parameters are important if using
infrared cameras. They display the connection between the distance of the measured object and the size
of the pixel (
Table 2).
With the help of BI-SPECTRAL technolo g y at PI200/ 2 30, a visual image (VIS) can be combined with a
thermal image (IR). Both can be finally captured time synchronously:

Table 2: Table with examples showing what spot sizes and pixel sizes will be reached in which distance. For
individual configuration there are different lenses available. Wide angle lenses have a radial distortion due to their
large opening angle; the software PIConnec t has an algorithm which corrects this distortion.
* Note: The accuracy of measurement can be outside of the specifications for distances below the defined minimum distance.
