two right triangles "C1" and "C2". Once these two values are known, the LDM can
solve two Pythagorean equations for the missing values of the other two legs
("A1" and "A2"). The final calculation, which solves for A—the height of the
building—is A = A1 + A2.

• Auto height measurement. Using a slightly
different technique (see Fig. 10), the LDM can
quickly calculate the height of any object using
only two inputs.
Fig. 10. Automatic calculation of a height using
two inputs
To measure the height of an object using triangulation
with two inputs:
1. First make sure that the line of sight from the LDM to the bottom of the object
forms a right angle.
2. Use the
reference. Also make sure the laser is on.
3. Press the
display with the hypotenuse flashing.
4. Aim the laser at the top of the object and press the
measured (the hypotenuse) will appear on the second line of the display and the
horizontal leg of the on-screen triangle will begin flashing.
5. Without moving the LDM, and keeping it as horizontal as possible, aim the laser
at the bottom of the object and press the
will appear on the third line of the display and the height of the object will appear
on the bottom (summary) line. The final display will look similar to Fig. 11 at the
top of the next page.
