becomes diffuse. The targeting light only marks the center of the measuring spot, not the size.

A measuring tape can also be used to determine the distance between the object and

pyrometer.

If the pyrometer is supplied with power, the LED targeting light is automatically active. If the

targeting light does not activate, check whether the pyrometer is properly connected to the

power supply (consult the window pyrometer parameters in Chapter 4 for more information).

It is possible to connect a push button to the pyrometer to switch the targeting light on and off

(see Section 3.1.1, Pin assignment of the male socket on the back of the pyrometer).

3.3 Optics

The pyrometers are equipped with one of the following optics. Optics focus to a certain

distance, i.e. at these distances each optics achieves its smallest spot size in relation to the

measuring distance. The spot size will change at any other distance (shorter or longer).

Note: The measuring object must be as least as big as the spot size.

The drawing and the table below illustrate the size of the spots in mm in relation to the

measuring distance. Values between the data shown below can be calculated by interpolation.

The spot size for measuring distance 0 is the aperture diameter “D” of the optics.
