Fig. 9. Triangulating a height
using three inputs

To measure the height of an object using triangulation
with two inputs:

1. First make sure that the line of sight from the meter to the

bottom of the object forms a right angle.

2. Use the

button to choose the front edge of the meter as the

measurement reference. Also make sure the laser is on.

3. Press the button once. A

icon will appear on the left side

of the display with the hypotenuse flashing.

4. Aim the laser at the top of the object and press the

button.

The distance 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 meter, and keeping it as horizontal as

possible, aim the laser at the bottom of the object and press
the

button. The distance measured 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. 10.
