1. 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 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.
Please take care of the following notes:
Notes
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
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.
The mounting should be made only via the mounting threads or tripod connection the
housing is providing.
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.

5. Optical Datas
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 (please see tables at the end of this section).
With the help of BI-SPECTRAL technology at optris PI200, a visual image
(VIS) can be combined with a thermal image (IR). Both can be finally
captured time synchronously:
Note
Please make sure that the focus of thermal channel and visual channel (optris PI200 only) is
adjusted correctly. For focusing the thermal camera please turn the lens, for focusing the visual
camera please use the focusing tool supplied in the scope of delivery.

7. Electrical Installation
At the back side of the PI you will find two connector plugs. Please connect the supplied USB cable with the
right plug. The left connector plug is only used for the process interface.
Process Interface
The PI is equipped with a process interface (cable with integrated electronics and terminal block), which can
be programmed via the software as an Analog Input (PIF in) and Digital Input (Dig In) in order to control the
camera or as an Analog Output (PIF out) in order to control the process. The signal level is always 0-10 V.
Note
Please make sure that the process interface (electronics within cable as well as industrial interface)
is powered separately (5-24 VDC).
