3.2 LED targeting light
The pyrometers are equipped with an LED targeting light for aiming onto the measuring object.
The center of the light marks the center of the spot. For use of this targeting light, a separate
power supply is necessary with 5 ... 30 V DC and a current of I ≤ 30 mA.
Measuring is possible while the LED targeting light is on. We recommend using a low supply
voltage to keep the thermal loading of the pyrometer small.
3.3 Optics
The pyrometers are equipped ex works with one of the following optics. These optics focus to a
certain distance, i.e. in these distances each optics achieves its smallest spot size in relation to
the measuring distance. The spot size will change in any other distance (shorter or longer).
Please note that the measuring object must be as least as big as the spot size.
