Objectives
This course prepares for qualification as a category 1 certified thermographer. The participants will learn about the basics of infrared, how to operate the camera under different conditions and for various purposes, how to do an appropriate judgement of the measurement situation in the field and identify potential error sources. You will be able to do IR inspections following written guidelines and to
report the result of this inspection. -
