-General notes 7-

The CS sensing head is a sensitive optical system. Please use only the thread for mechanical
installation.

 Avoid abrupt changes of the ambient temperature.
 Avoid mechanical violence on the head – this may destroy the system (expiry of warranty).

 If you have any problems or questions, please contact our service department.

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.

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

1 General notes

1.1 Intended use

Thank you for choosing the optris® CS infrared thermometer.
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]

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 non­intended 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.

1.3 Scope of delivery

 CS incl. connection cable
 Two mounting nuts
 Quick start guide

-General notes 9-

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

1.4 Maintenance

Blow off loose particles using clean compressed air. The lens surface can be cleaned with a soft, humid
tissue (moistened with water) or a lens cleaner (e.g. Purosol or B+W Lens Cleaner).

Smart Averaging means a dynamic average adaptation at high signal edges.
[Activation via software only]. [►Appendix D – Smart Averaging]

The default settings can be changed with the optional USB kit (USB adapter cable + software). If
the unit is supplied together with the USB kit the output is already preset to digital
communication (bidirectional).
