DISTANCE TO SPOT RATIO
The distance-to-spot ratio is a representation of how focused the IR sensor
is on the measurement area. The closer you are to the surface you are
measuring, the smaller the area of measurement is.
The IR3000 has a 30:1 distance-to-spot ratio. This means that if you are
30 feet away from an air vent, the vent should be 1 foot or less in diameter
in order to resolve the most accurate measurement.
Below is an illustration of other example measurements.
