-General Information 7-
The CTvideo 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® CTvideo infrared thermometer.
The sensors of the optris CTvideo series are noncontact infrared temperature sensors.
They calculate the surface temperature based on the emitted infrared energy of objects [►10 Basics of
Infrared Thermometry]. The alignment of the sensor can be done with the integrated video sighting and
crosshair laser aiming.
The sensor housing of the CTvideo head is made of stainless steel (IP65/ NEMA-4 rating) – the sensor
electronics is placed in a separate box made of die casting zinc.

► 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.

Optics
Focus adjustable in the range
SFV
200 mm till infinity
CFV
90 mm till 250 mm
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.
2.6 Optical Charts
The vario optics of the CTvideo allows a smooth focusing of the optics to the desired distance. The sensors
are available in two optic versions:
The following tables show the diameter of the measuring spot for some selected distances. 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
http://www.optris.com/spot-size-calculator.
