7.
  Measure the height (Figure 
M
 
3
).
•  Positon the tool at one end of the object and 
point the laser dot across the height.  
(Figure 
M
  3  shows where to position the 
tool if you are measuring from the bottom of 
the tool).
•  Press   to display the height measurement 
on the third line of the screen.
8.
  View the Volume measurement at the bottom of 
the screen (Figure 
M

).
Adding/Subtracting 2 Volumes 
You can measure the volume of room or object 
and then add it to, or subtract it from, the volume of 
another room or object (Figure 
N
).
1.
  Point the tool's laser (Figure 
A
 
1
) toward a wall 
or object, and not toward anyone's eyes.
2.
  Press   (Figure 
A
 
3
) to turn the tool on and 
display the red laser dot.
3.
  Make sure the tool position setting (Figure 
E
 
4
) 
is correct for taking the measurement.
4.
  If   is not already displayed as the current 
function (Figure 
E

), click the current function 
icon and then select   from the list of 
functions (Figure 
G
 
2
).
5.
  Click + to add, or - to subtract, the volumes of two 
objects.
6.
  Measure the width (Figure  N   1 ).
•  Position the tool at one end of the object and 
point the laser dot across the width.  
(Figure 
N
 
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 (Figure 
N
 
2
).
•  Position the tool at one end of the object and 
point the laser dot across the length. (Figure 
N
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.
  Measure the height (Figure 
N
 
3
).
•  Position the tool at one end of the object and 
point the laser dot across the height. (Figure 
N
 
3
 shows where to position the tool if you are 
measuring from the bottom of the tool).
•  Press   to display the height measurement on 
the third line of the screen.
9.
  Follow the same steps to measure the width, 
length, and height of the second room or object.
10.
 View the Volume measurement at the bottom of 
the screen (Figure 
N
 
4
).
Measuring the Height of a Tall Object
If you need to measure the height of a tall object 
(e.g., a tall building), you can calculate the height 
based on the distance to 1 point or the distances 
from the same point to 2 points on the object. The 
tool will use the Pythagorean Theorem (C
2
=A
2
+B
2
) to 
calculate the height.
Distance to 1 Point 
You can use the distance to one point on a wall 
or object (Indirect Height) to determine its height 
(Figure  O ).
1.
  Point the tool's laser (Figure 
A
 
1
) toward a wall 
or object, and not toward anyone's eyes.
2.
  Press   (Figure 
A
 
3
) to turn the tool on and 
display the red laser dot.
3.
  Make sure the tool position setting (Figure 
E
 
4
) 
is correct for taking the measurement.
4.
  If   is not already displayed as the current 
function (Figure 
E
 
5
), click the current function 
icon and then select  from the list of functions 
(Figure 
G
 
2
).
5.
  Position the tool opposite the bottom of the 
vertical height to be measured (Figure 
O
 
1
).
6.
  Point the laser toward the highest point of the 
building or object whose height you need to 
measure (Figure  O   1 ).
7.
  Press   to measure the distance.
8.
  View the height measurement at the bottom of the 
screen (Figure 
O
