7 Proportion between the distance from probe to object
and the diameter of the object to be measured (D:S)
Temperature measurement meter has a certain angle and field of vision, as shown in the
diagram below:
It must be ensured that the object to be measured is fully within the field of vision afforded
by the temperature measurement meter, that is, the meter can see nothing but the object
to be measured. The greater the object to be measured is, the farther the distance detected
by the meter may be. The smaller the object is, the shorter the distance to be measured
must be. The proportion between the distance to be measured and the size of the object to
be measured (D:S) is 12:1, as shown in the diagram below.
While measuring an object, the instrument will emit an indicative ring. The measured
temperature of the surface is the internal temperature of the ring.
