15. INFRARED CAMERA BEHAVIOUR

Infrared camera behaviour
15.1 Infrared camera warm-up
Modern infrared cameras are based on a sensor (microbolometer array) that needs to be warmed-up to the
working temperature before it can be used. The sensor starts warming-up automa cally when the user turns
Workswell WIRIS system on. The infrared camera is usually ready in less than 5 minutes.
During the warm-up process the accuracy of the measured temperature data is lower and various defects can
appear in the thermal image. Therefore, we recommend to let the infrared camera warm before using it.
15.2 Non-uniformity correc on
Infrared camera needs to be periodically calibrated in order to get reasonable measurement accuracy. This pro-
cess is called Non-uniformity correc on (NUC) and is done automa cally. The user can set calibra on period in

TIME TO CALIB. Time to next calibra on is shown in STATUS BAR.
It is recommended to use shorter periods (2 – 5 minutes) during camera warm-up process and longer periods
(10 – 30 minutes) when the camera is already warmed-up.
Warning: Using only short periods (2 – 5 minutes) for a long me can cause early camera damage.
