The Impulse 200 takes five basic measurements. Two —slope distance and inclination—are measured
directly. The remaining three—horizontal distance, vertical distance, and percent slope—are calculated. The
Impulse 100 has no way to measure angles, and takes only slope distance measurements. The five
measurements are related; the relationships among them are illustrated here:
Measured
Calculated
slope
distance
horizontal distance
inclination
vertical
distance
"Percent slope" is 100 * tan(inclination)
To get a feel for how the Impulse operates, choose a target near you. For the purposes of this exercise, the
target can be as prosaic as, say, a wall at the end of the corridor outside your office or the fence around your
back yard. Then make the button presses indicated in the table. The procedure assumes that you are starting
from scratch, with the Impulse powered off.
