Distance & Spot Size
As the distance (D) from the object increases, the spot size (S) of the area
measured becomes larger. The meter's D:S ratio is 10:1, so at 10 inches (254mm),
the diameter of the target being measured must be at least 1" (25.4mm).

NOTE:
• Make sure that the target is larger than the spot size displayed by the
Distance: Spot diagram printed on the side of the meter.
• If the surface area is highly reflective, apply electrical tape or flat black
paint to surface before measuring. Allow time for tape or paint to adjust
to temperature.
• The meter cannot measure through transparent surfaces such as glass.
It will measure the surface temperature of the glass instead.
• Steam, dust, smoke, etc., can block measurements.
• Make sure the surface being measured is free of frost, dirt, oil, etc.
• The meter automatically corrects for changes in ambient temperature.
However, it can take up to 30 minutes to adjust to wide variations.
