Infrared Camera Behavior
20.1 Infrared Camera Warm-Up
Modern infrared cameras based a microbolometer array need to internally warm up to their working temperature
before the measured values stabilize. The sensor begins to automa cally warm up a er user turns the camera
on. The infrared camera is usually up to ideal internal temperature in about 15 - 30 minutes. There is a mer
indica ng the Hea ng Up period of the camera a er every start. During this period, the alarms are turned off.
It is recommended to let the camera warm up another 15 minutes to ensure best measured results. If you want
to skip the wai ng period (not recommended) go into MENU > MEASURE and follow the warning instruc ons.
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 up before measuring
cri cal data.
20.2 Non-Uniformity Correc on (NUC)
Infrared cameras needs to be periodically calibrated in order to get reasonable measurement accuracy. This
process is called Non-uniformity correc on (NUC) or shu er calibra on. MEDICAS is equipped with an internal,
automated shu er which is triggered automa cally in a set interval.
Note:
Even a er NUC is performed, temperature non-uniformity can, depending on the environmental
circumstances, s ll reach up to 4
◦
C. It recommended to send the camera to Workswell s.r.o. a er 12
months of usage for SFFC calibra on and camera op c system maintenance.
