Welcome!
Thank you for choosing the optris PI thermal imager!
The optris PI calculates the surface temperature based on the emitted infrared energy of objects [►Basics of
Infrared Thermometry]. The two-dimensional detector (FPA - focal plain array) allows a measurement of
160 x 120 pixels and will be shown as thermographic 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 optris 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 power laser or reflexions of such
equipment, e.g.) can have effect on the accuracy of the measurement or can cause an irreparable
defect of the infrared detector.
The mounting should be made only via the mounting threads or tripod connection the housing is
providing.

Maintenance
Lens cleaning: Blow off loose particles using clean
compressed air. The lens surface can be cleaned with a soft,
humid tissue moistened with water or a water based glass
cleaner.
PLEASE NOTE: Never use cleaning
compounds which contain solvents
(neither for the lens nor for the housing).
Cautions
Avoid static electricity, arc welders, and induction heaters. Keep away from very strong EMF (electromagnetic
fields). Avoid abrupt changes of the ambient temperature.
In case of problems or questions which may arise when you use the infrared camera, please contact our service
department.

The signal level is always 0-10 V.
Start-Up
Please install at first the software PIConnect from the CD, as described in the next chapter. The CD contains the
software application as well as the unit specific calibration data. These data will be installed also automatically.
Now you can connect the infrared imager to a free USB port (USB 2.0) of your PC.
After the software has been started, you should see the live image from the camera inside a window on your PC
screen.
The sharpness of the image can be adjusted by turning the exterior lens ring.
