-General Information 7-

The CSmicro 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.

1 General Information

1.1 Description

Thank you for choosing the optris® CSmicro infrared thermometer.
The sensors of the optris CSmicro series are noncontact infrared thermometers.
They calculate the surface temperature based on the emitted infrared energy of objects
[►8 Basics of Infrared Thermometry].
The sensor housing of the optris CSmicro is made of stainless steel (IP65/ NEMA-4 rating) – the sensor
electronics is integrated inside the connection cable.

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

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.

1.3 Scope of Supply

 CSmicro incl. connection cable
 Mounting nut
 Isolated mounting bracket (only included for LTH devices)
 Operators manual

-General Information 9-

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

1.4 Maintenance

Lens 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 lens cleaner (e.g. Purosol or B+W Lens Cleaner).
