Distances to 2 Points 
You can use the distance to two points on a wall 
or object (Double Indirect Height) to determine its 
height (Figure  P ).
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 approximate 
center of the vertical height to be measured 
(Figure 
P   1 ).
6.
  Point the laser toward the lowest point of the 
building or object whose height you need to 
measure (Figure 
P
 
1
).
7.
  Press   to measure the distance.
8.
  From the same point, aim the laser at the 
highest point of the building or object  
(Figure 
P
  2 ).
9.
  Press   to measure the distance.
10.
 On the bottom line of the screen, view the height 
of the building or object (Figure 
P
  3 ).
Measuring Partial Height 
If you need to determine the height of a section of 
a wall or object (e.g., the distance from the ceiling to 
the top of TV or window on the wall) (Figure 
Q
).
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.
  Point the laser at the highest point of the wall or 
object (Figure 
Q
 
1
).
6.
  Press   to measure the distance to the top of 
the object.
7.
  From the same point, aim the laser at the top 
of the obstruction (TV, window, etc.) on the wall 
or object (Figure 
Q
 
2
).
8.
  Press   to measure the distance from the top 
of the wall to the obstruction.
9.
  From the same point, aim the laser on 
a horizontal line straight ahead toward the 
bottom of the wall (Figure 
Q
 
3
).
10.
 Press   to measure the distance.
11.
 On the bottom line of the screen, view the 
distance between the top of the wall and the top 
of the obstruction on the wall (Figure 
Q
  4 ).
Measuring Height of Obstructed Object 
Follow these steps to determine the height of a tall 
building or object that is blocked by other buildings 
or objects (Figure 
R
).
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
 
3
).
5.
  Point the laser at the highest point of the 
building, wall, or object (Figure 
R
 
1
).
6.
  Press   to take the measurement.
7.
  On the bottom line of the screen, view the height 
of the building or object (Figure  R  
2
).
