1 General notes
1.1 Intended use
The optris PI LightWeight Kit consists of a miniaturized lightweight PC (PI NetBox LW) and a weightoptimized optris PI400 LW or PI450 LW infrared camera. The system is ideally suited for radiometric
infrared recordings from the air like for maintenance work and quality inspections of solar and wind
power systems and for building thermography.
The PI NetBox LW (Miniature-PC) includes a Windows XP Professional operating system that allows
on-flight recording of infrared videos with up to 35 Hz.
The optris PI 400 LW or 450 LW calculates the surface temperature based on the emitted infrared
energy of objects [► 6 Basics of Infrared Thermometry]. The two-dimensional detector (FPA - focal
plane array) allows a measurement of an area which will be shown as thermal image using
standardized color palettes. The radiometric processing of the picture data enables the user to do a
comfortable detailed analysis with the software PI Connect retrospectively.
8
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.
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.
• 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 contact our service department.

General notes
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 components. Warranty does not apply to damages, which result from misuse or
neglect. The warranty also expir es 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.

General notes
1.4 Maintenance
1.4.1 Cleaning
The housing of the NetBox LW can be cleaned with a soft, humid tissue moistened with water or a water
based cleaner.
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.
Never use cleaning compounds which contain solvents (neither for the lens nor for the
housing).
Take care that no foreign substances penetrate into the venting slots of the NetBox
LW.

Figure 3: Focusing of the lens

Lens
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 (see
Table 1).
• Make sure that the focus of the infrared camera is adjusted correctly. For focusing
turn the lens (Figure 3).
• For the PI 400 LW and PI 450 LW two different lenses are available: 38° x 29° and
62° x 49° FOV.
22
Table 1: 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 PIConnect an algorithm which corrects this distortion.
* Note: The accuracy of measurement can be outside of the specifications for distances below the defined minimum distance.

Installation
3 Installation
The PI 400 LW/ 450 LW are equipped with two metric M4 thread holes on the bottom side (6 mm depth)
and can be installed either directly via these threads or with help of the tripod mount (also on bottom
side). The separate PI camera sensing head can be mounted on the stabilization platform of a drone
together with a visual camera (in the picture: GoPro camera). The NetBox PC can be mounted
separately.
