EMISSIVITY

Target

The amount of infrared

energy radiated by an

object depends on its

emissivity and its

temperature.

The emissivity depends

on the material and its

surface characteristics.

For more accurate

readings, adjust the

emissivity value for the

type of material being

measured

The “Setup” DIP switch

(located inside the unit’

handle) must be in the

“ON” position to adjust the

emissivity.

When the trigger is pulled,

the display will show an

emissivity value (4). To

set it to another value,

use the up and down keys

(C).
