HEIGHT MEASUREMENT USING

PYTHAGOREAN METHOD

See Figure 9.

The laser distance measurer uses the Pythagorean method

+ b

= c

) to calculate heights that are otherwise difficult

to access.

Height - Pythagorean method

These instructions must be followed exactly for best re-

sults.

 All target points must be vertical or horizontal surfaces.

 Measurements should be taken from a fixed point (for

example, placed against a wall).

 From the icon menu, select the triangle icon.

 The dotted line indicating the base (a) will begin flashing.

 Position the device for a horizontal measurement, which

will be calculated from the bottom of the device.

 Tap the Laser button. The measurement will be displayed

on the screen.

 Tap the large button. The distance measured will be

identified (Base of triangle).

 Angle the device to take a second measurement from the

same orientation as the base measurement.

 The dotted line indicating the hypotenuse (b) will begin

flashing.

 Tap the large button. The distance measured will be

identified (Hypotenuse of triangle).

 The measurement for height (c) will be displayed on the

screen.
