3. Keep your position stable and press the button. The “C”
measurement will appear above the main display.
4. Aim the Laser Distance Meter so that the laser dot is on the
selected target to measure the length “D” in the figure above.
5. Keep your position stable and press the button again. The “D”
and “C” measurements will appear above the main display.
6. Aim the Laser Distance Meter so that the laser dot is on the
selected target to measure the length of the base (represented by
“A” in the figure above).
7. Keep your position stable and press the button again. The “A”
and “D” measurements will appear above the main screen. The
indirect height will appear on the main screen (represented by “B”
in the figure above). The laser will turn off.
8. Press the button to clear the display and take your next
3-Point Pythagoras measurement.
3-Point Partial Pythagoras Measurement Mode
Similar to the 2-Point and 3-Point Pythagoras
measurement mode, the 3-Point Partial
Pythagoras measurement mode indirectly
measures lengths that are otherwise not
directly measureable.
Typically, the Laser Distance Meter is used to measure a partial
height, shown above as “B”, when there is no target at the top
surface at which to aim the laser, such as a tall wall. The measurement
can be taken by standing back at some distance “A” and taking
measurements of “C” and “D” (on the side of the wall) and “A”
(aimed level at the wall).
