Alignment with the LED targeting light
For exact measurement of the object temperature the pyrometer must be aligned correctly
onto the object. For this alignment the pyrometers are equipped with a LED targeting light.
This light enables the simple and accurate alignment even onto small objects.
The light point marks the center of the spot, not the exact size. The correct focusing distance
with the smallest spot size is achieved when the LED point has its smallest size. The targeting
light does not effect the temperature measurement.
