10 Setup

The infrared temperature sensor uses the intensity of infrared radiation for non-

contact temperature measurements� It is necessary to configure the infrared tem-

perature sensor to the respective emissivity coefficient of the measuring object to

obtain exact measuring results (→ 13 Emissivity coefficient tables). An incorrectly

set emissivity coefficient leads to wrong temperature readings�
Set the emissivity coefficient after connecting the supply voltage or resetting the

parameters to factory settings�

The display then shows three horizontal strokes [

%%%%

]�

The emissivity is set as follows:

►

Press [Enter]

> The display shows [

EPS1

]

►

Press [Enter]

> the display shows [

nonE

]

► [▼] hold key until the required value is displayed

►

Press [Enter]

> The current temperature value is displayed� The infrared temperature sensor

now works with this configured emissivity until it is changed again�
