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]
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 [ ].

1.2 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.
1.3 Scope of delivery
• CS incl. connection cable
• Two mounting nuts
• Quick start guide

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

2.5 Optical charts
• 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.
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.

As an alternative to the optical diagrams, the spot size calculator can also be used on the
Optris website (https://www.optris.global/spot-size-calculator) or via the Optris calculator app.
The app can be downloaded for free from the Google Play store (see QR code).
D = Distance from front of the sensing
head to the object
S = Spot size

2.6 Close focus optics
• If the CF-lens is used, the transmission has to be set to 0.78. To change this value the
optional USB-Kit (including software) is necessary.
• The assigned transmission (average value) is a characteristic value which may has a certain
scattering. If required the transmission has to be determined.
The optional CF-lens allows the measurement of small objects. The CF optics can also be combined with a
laminar air purge

2.7 LED-Functions
The green LED can be programmed for the following functions. For the programming the USB adapter
cable incl. software (option) is necessary. The factory default setting for the LED is self-diagnostic.
LED Alarm
LED lights up ifthe object temperature exceeds ordeceedsan alarm threshold
Automatic aiming support
Sighting feature foran accurate aiming ofthe CS to hot or cold objects
Self-diagnostic
LED is indicating different states of the sensor
Temperature Code indication
Indication of the object temperature via the LED
Off
LED deactivated
2.7.1 Automatic aiming support
The automatic aiming support helps to adjust the unit to an object which has a temperature different to the
background. If this function is activated via software the sensor is looking for the highest object temperature;
means the threshold value for activating the LED will be automatically tuned.
This works also if the sensor is aimed at a new object (with probably colder temperature). After expiration of
a certain reset time (default setting: 10 s) the sensor will adjust the threshold level for activation of the LED
new.
