Operating principle

IR thermometers measure the surface temperature of an object. The sensor on the device records the
heat radiation emitted, reflected and transmitted from the object, and converts this information into a
temperature value. The emission level is a value used to describe the energy radiation characteristics
of a material. The higher the value, the more capable the material is of emitting radiation. Many
organic materials and surfaces have an emission level of approx. 0.95. Metallic surfaces or shiny
materials have a lower emission level and therefore return inaccurate measured values.
Measurement distance / measurement surface area ratio (D/S)
• To achieve accurate measurements, the target must be larger than the thermometer's measuring
area. The measured temperature is the average temperature of the area measured.
• The smaller the target, the smaller the measurement distance between thermometer and target
object has to be.
• The distance to target / size of IR focal spot ratio is 50:1. With a distance of 50 cm to the target, the
size of the IR focal spot is thus 1 cm.

Restore the device
1. Use the button photo / up arrow (5) and the button video / down arrow (3)
to set this function with "YES" and "NO"
2. Press the button ESC / power (4) to save and go back to the previous
menu. The setting will be restored to the factory default.
