Adding/Subtracting 2 Areas 
You can measure the area of a wall, floor, or object 
and then add it to, or subtract it from, the area of 
another wall, floor, or object (Figure 
L
).

  Point the tool's laser (Figure 
A
 
1
) toward a wall 
or object, and not toward anyone's eyes.
2.
  Press   (Figure

).
•  Position the tool at one end of the target (wall, 
floor, or object) and point the laser dot across 
the width. (Figure  L   1  shows where to 
position the tool if you are measuring from the 
bottom of the tool.)
•  Press   to display the width measurement at 
the top of the screen.
7.
  Measure the length of the first wall, floor, or

L
 
2
 shows where to position the tool if you are 
measuring from the bottom of the tool.)
•  Press   to display the length measurement 
on the second line of the screen.
8.
  Follow the same steps to measure the width and 
length of the second wall, floor, or object.
9.
  View the Area measurement at the bottom of the 
screen (Figure
