Notes regarding the Measuring Distance
When the distance d to the object to be measured is increased, the
measuring radius r increases as well (the wider the distance to the
object to be measured is, the more imprecisely the measuring result
will be). The area to be measured / the object to be measured
should be bigger than the according measuring radius. If the object
to be measured is small, hold the thermometer close to the object.
r:d = 1:12

Example:
Radius (r) = 1 cm, Distance (d) = 12 cm
