General IRT102 Mode D'emploi page 7

Fig. 4. The IRT102's field of view
For example, when using the IRT102 to measure the
temperature of a motor with an area of 1 ft
measurement distance would be 6 ft. To eliminate error, the
IRT must be moved close enough so the motor is the only
object in the target area (see Fig. 5 bottom).
