Distance-Spot Ratio
The Lasergrip 774 measures surface
t e m p e r a t u r e o n t h e b a s i s o f d i s t a n c e
to spot diameter ratio (D:S). As the
distance between the thermometer and
the surface increases, the total surface
area measured will also increase. With a
distance to spot ratio of 12:1 the surface
area measured has a diameter of
roughly 1/12 the distance.
For the most accurate results, make
s u r e t h e t a r g e t h a s a s u r f a c e a r e a o f
twice the corresponding spot diameter.
t h e
An insufficient surface area will result
in inaccurate results. The recommended
distance to hold the Lasergrip from the
surface of measurement is 14. 17in (36
cm). This creates a spot measurement
area of 1 .1 8 inches ( 3 cm) in diameter.
