General notes
1 General notes
1.1 Intended use
The sensors of the optris CS series are non-contact infrared temperature sensors. They calculate the
surface temperature based on the emitted infrared energy of objects [►7 Basics of Infrared
Thermometry]
The CS sensors are sensitive optical systems. Use the thread for mechanical
installation only. Avoid mechanical violence on the head – this may destroy the system
(expiry of warranty).
•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.

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 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.
►All accessories can be ordered according to the referred part numbers in
brackets [ ].
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.

1.4 Maintenance
1.4.1 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.
Never use cleaning compounds which contain solvents (neither for the lens nor for the
housing).

2.5 Optical charts
The following optical charts show the diameter of the measuring spot in dependence on the distance
between measuring object and sensing head. The spot size refers to 90 % of the radiation energy.
The distance is always measured from the front edge of the sensor housing/ CF-lens holder/ air purge.
Figure 1: Optical chart CS (15:1)
•The size of the measuring object and the optical resolution of the infrared
thermometer determine the maximum distance between sensing head and
measuring object.
•In order to prevent measuring errors the object should fill out the field of view of the
optics completely. Consequently, the spot should at all times have at least the
same size like the object or should be smaller than that.
