The IR thermometerHT-280H can perform different measuring functions.
To access setup mode, press the button „SET“ when the thermometer is turned on (button
„MEAS“).
The „SET“ button takes you to the next respective menu point and the button „LASER“ changes
the parameters. The active function is displayed on the display.

• The emission degree described the energy emission characteristics of a material. The higher this value is, the more
radiation
a material may emit (thermal radiation). Many materials have a value that is close to the preset value „0.95“ of the IR
thermometer.
Metallic shiny surfaces have a lesser degree of emission than
matte black surfaces.
Therefore, the degree of emission must be preset accordingly.
In this case, attaching an adhesive strip (or lacquer with matte black paint, if possible), helps to be able to measure with
the common emission degree of 0.95.
• Measuring through a glass pane is not possible, instead, the temperature of the glass pane is displayed.
