MEASURING AREAS
The LDM60 can calculate the area of a square or rectangular
room or space by measuring its length and width and multiplying
the two values.
To measure an area:
1. Make sure the meter is using its rear edge as the
measurement reference and that the laser is on.
2. Press the button once. A icon will appear on the left
side of the display with its top line flashing.
3. Holding the rear of the meter against one wall of the room or
space, aim the laser pointer at the opposite wall and press the
button. The distance measured will appear on the second
line of the display, the top line of the rectangle will stop
flashing, and the right side of the rectangle will begin flashing.
4. Move the meter to an adjacent wall of the room or space and
hold its rear against that wall. Aim the laser at the opposite
wall and press the
button. The distance measured will
appear on the third line of the display and the area of the room
or space—in “square” units—will appear on the bottom line.
The final display will look similar to Fig. 12.
