Testing. Pages 13-1 through 13-28.
Learning Objective: Display a
basic familiarity with the
electronic distance measurement
(EDM) system by identifying
related processes and devices.
11-1.
In the EDM system, a linear
distance can be computed by
multiplying the time it takes a
flash of light to travel a given
distance by the velocity of the
light.
