Reflected Temperature Compensation 2

2-13

Reflected Temperature Compensation

Targets that have low emissivities will reflect energy from nearby objects. This additional

reflected energy is added to target’s own emitted energy and may result in inaccurate

readings. In some situations objects near the target (machines, furnaces, or other heat

sources) have a temperature much higher than that of the target. In these situations it is

necessary to compensate for the reflected energy from those objects. The concept of

reflected temperature compensation is illustrated in Figure 2-5.

Note

The Reflected Temperature Compensation (RTC) feature is disabled when

the emissivity is set to 1.00.
