Single Pythagorean Theorem measurement mode
The Pythagorean Theorem measurement mode is used
to measure distances that cannot be measured direct-
ly due to an obstacle obstructing the laser beam or if
no target surface is suitable as the reflector. Correct
results can only then be achieved if the laser beam
and the relevant distance produce a precise right angle
(90°).
The length of BC is to be determined in the illustrated
example (fig. 15). The section AB and AC must be
measured for this purpose. AC and BC must form a
right angle.
1. Press the Mode button (4) to select the single
Pythagorean Theorem measurement mode (fig. 16).
2. The flashing line in
to be measured.
3. Press the Read button to activate the laser beam;
the laser indicator will flash.
4. Position the device in such a way that the laser is
aimed at point B.
5. Press the Read button to display the measured
length of AB on the first line of the screen (fig. 17).
6. The flashing line in
be measured.
7. Without changing device position A aim the laser
perpendicularly at target C.
8. Press the Read button again to display the calcula-
ted length of BC on the bottom line of the screen;
the distance AC is simultaneously displayed on the
second line (fig. 18).
9. Press the Read button to conduct a new measure-
ment.
Note:
• The distance AC must be shorter than the hypotenuse (AB); if not, "Err008" will appear on the display
reminding you to measure the distance of AC again.
• When conducting the two measurements make sure they are taken from the same starting point (A)
and that the second measurement is perpendicular to the target (C). Accuracy when conducting the
measurements will help to produce the most accurate distance calculation.
