Maximum distance and size of measurement point
Size of measurement target and optical features of infrared thermodetector determine maximum distance between measurement target and measurement head. To prevent measurement error, the measurement target should fill field of view of probe as much as possible. Therefore, always keep measurement point smaller than measurement object or at least the same size as measurement target.

When adjust measurement target and measurement head, ensure that optical path is barrier free, as shown below:
