IMPORTANT CONSIDERATIONS

• Before measuring any surface, make sure it is clean.
• Measurements made through transparent surfaces such as glass may not be
accurate.
• Make sure that the object is always larger than the measurement area; If the size of
the object is reduced, you should bring the thermometer closer.
• Pay attention to the distance
between the thermometer and
the measuring area. If the
distance (D) increases, the size
of the point (S) of the measured
area becomes larger.
