1 General notes
1.1 Intended use
Thank you for choosing the optris®BR 20AR reference source.
The BR 20AR is a rugged reference source and ideally suited for referencing thermal imaging cameras. It
contains two main components:
Radiation surface
Temperature probe (16-bit digital temperature sensor with 0.1 °C accuracy)
The radiation surface is made of aluminium with a special thermal conductivity and has shaped grooves. The
BR 20AR is floating with the ambient temperature. The temperature is measured with a higher precision
temperature probe.
To avoid a damage of the special coating, please do not touch the radiation surface with
sharp or spiky objects.
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 please 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 components. 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.

3 Installation
3.1 Hardware installation
A possible configuration of the BR 20AR is shown in Figure 4. The optris
PI 450i T010 camera is connected via USB to the computer. The included
20 m cable has to be connected to the PIF connector on the camera back
side (see Figure 3). There is no power supply necessary for the
BR 20AR.
Hardware and Software Recommendation:
Computer with OS Windows 7 or higher
Optris PI 450i T010 camera and PIX Connect Software Version
3.9.3063.0 or higher
Figure 3: Connection
Note:
The camera must be focused
Consider the minimum distance of the selected optics
The reference source must not be obscured by other objects
