The unit of surface temperature (°C, °F) is set in configuration area
Unit 1 in this mode. °C is set at the factory.
An offset correction of the temperature values can be made in confi-
guration area CAL 1.
The laser light is switched on for measurement location marking as
soon as the IR mode is selected. The laser lights for a maximum of
2 minutes and can be activated for another 2 minutes respectively with
a at any time in this mode.
Distance and measuring spot size (E:M)
To achieve accurate measuring results the target must be larger than
the measuring spot of the instrument. The determined temperature is
the average temperature of the measured surface. The smaller the
target the shorter the distance from the instrument must be. The exact
measuring spot size can be taken from the diagram. For accurate
measurements, the target must be at least twice as big as the
measuring spot.
