MEASURING AREAS & PERIMETERS
The LDM can calculate the area of a square or rectangular room or space by
measuring its length and width and multiplying the two values. It can also calculate
the perimeter of the room or space by adding the length and width and mulitplying
by two.
To measure an area or perimeter:
1. Make sure the LDM is using its bottom as the measurement reference and that
the laser is on.
2. Press the
with its bottom leg flashing.
3. Holding the bottom of the LDM against one wall of the room or space, aim the
laser pointer at the opposite wall and press and hold the
distance measured will appear on the top line of the display, the bottom leg of
the parallelogram will stop flashing, and the right leg of the parallelogram will
begin flashing.
4. Move the LDM to an adjacent wall of the room or space and hold its bottom
against that wall. Aim the laser at the opposite wall and press the
button. The distance measured will appear on the second line of the display and
the area of the room or space—in "square" units—will appear on the bottom
line. The calculated perimeter of the room or space will appear on the third line
of the display. The final display will look similar to Fig. 13.
