5.1.3. Sensor Placement (2-Color Mode)

The following figure demonstrates the sensor placement under various conditions, where valid
2-color temperature measurements are possible. Note, however, that if the sensor signal is
reduced more than 95% (including emissivity and obscuration of the target), the sensor
accuracy also degrades.
