7. The Distance to Spot ratio for the imager is 30:1 meaning that the measurement
spot is 30 times smaller than the distance the meter is from the spot (at a distance
of 30”, the meter ‘sees’ a target spot of 1”). See Fig. 7-2.
8. The thermal imager’s FOV (Field of View) is 50 degrees (top view) and 38.6
degrees (side view); see Fig. 7-3 (a) and (b).
