1 General Information

1.1 Description

Thank you for choosing the optris® CSlaser infrared thermometer.
The sensors of the optris CSlaser series are noncontact infrared temperature sensors.
They calculate the surface temperature based on the emitted infrared energy of objects [►9 Basics of
Infrared Thermometry]. An integrated double laser aiming helps to mark the measurement spot on the
object surface. This lies within the two laser points.
The sensor housing of the CSlaser head is made of stainless steel (IP65/ NEMA-4 rating).

The CSlaser 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 [ ].

-General Information 7-

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

 CSlaser
 Mounting nut and mounting bracket (fixed)
 Connection cable (optional at connector version)
 Operators manual

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).

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

2.4 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 sensing head.

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.

As an alternative to the optical diagrams, the spot size calculator can also be used on the optris website

http://www.optris.com/spot-size-calculator.

D = Distance from front of the sensing head to the object
S = Spot size
