Emissivity rate (ε)
The emissivity rate is the rate of energy emitted from the surface of an object. Every object has
a unique emissivity rate which is variable according to the surface condition and temperature of
the object. This product allows for setting a desired emissivity rate, which can enable even more
precise measurement by adjusting the emissivity rate according to that of the target.
An object with low emissivity rate (e.g. a shiny metallic object) reflects the surrounding
temperature since it is highly reflective. If the surrounding objects have greatly different
temperature from that of the main unit, their temperatures are reflected resulting in incorrect
measurement. Therefore it is necessary to block out such effect.
The maximum emissivity rate is normally 1.00, but this unit is designed to accept up to 1.20 for
practical convenience.
(1) Aim the sensor head to the target.
Confirm the target is sufficiently larger than the field of view.
(2) In the Setting Operation select the Adjustment Setting, and then press Enter button.
(3) Select the TEACH Adjustment, and then press the ENTER button.
(4) The current measurement value is displayed.
Input the temperature of the target, and then press the ENTER button.
(5) Confirm that the measurement value and emissivity rate have been changed.

Error indication
If the emissivity rate calculated automatically in the TEACH Adjustment is out of the setting
range(0.1 to 1.2), an error(Err1) is displayed.
In this case, TECH Adjustment is cancelled. Perform Emissivity Rate Adjustment.
Input the emissivity rate directly.
Adjust the measurement value to the temperature value of the target.
The emissivity ratio is calculated automatically.
