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. 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.

Description
The sensors of the optris CSmicro series are noncontact infrared temperature sensors.
They calculate the surface temperature based on the emitted infrared energy of objects [►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.
Scope of Supply
CSmicro incl. connection cable
Mounting nut
Operators manual
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 water based glass
cleaner.
PLEASE NOTE: Never use cleaning
compounds which contain solvents
(neither for the lens nor for the housing).

Cautions
Avoid abrupt changes of the ambient temperature.
In case of problems or questions which may arise when you use the sensor, please contact our service
department.
The sensors CSmicro are sensitive optical systems. Please use only the thread for mechanical
installation.
Avoid mechanical violence on the head – this may destroy the system (expiry of warranty).
