Setting The Emissivity; Changing The Reflected Apparent Temperature - FLIR C Series User Manual

7 Operation

7.12 Setting the emissivity

Shiny metals and glass have low emissivities, giving wrong temperatires
7.12.1 General
To measure temperatures accurately, the camera must be aware of the type of surface you
are measuring. You can choose between the following surface properties:
It's hard to compansate for low emissivities. Advanced only
• Matt.
• Semi-matt.
• Semi-glossy.
As an alternative, you can set a custom emissivity value.
For more information about emissivity, see section 15 Thermographic measurement tech-
niques, page 59.

7.13 Changing the reflected apparent
temperature
Advanced Only
7.13.1 General
This parameter is used to compensate for the radiation reflected by the object. If the emis-
sivity is low and the object temperature significantly different from that of the reflected tem-
perature, it will be important to set and compensate for the reflected apparent temperature
correctly.
For more information about the reflected apparent temperature, see section 15 Thermo-
graphic measurement techniques, page 59.
