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 distances from the same point to 2 or 3 points on
the object. The tool will use the Pythagorean Theorem
(C
2
=A
2
+B
2
) to calculate the height.
• If the tool can be positioned opposite the bottom
of the tall object (to create an angle ≤ 45°), use
the distances to 2 points to calculate the height
(Figure
G
).
• If the tool must be pointed downward to aim at
the bottom of the tall object (to create an angle >
45°), use the distances to 3 points to calculate the
height (Figure
H
).
Using the Distances to 2 Points
1.
Click (Figure
A
3
) to turn on the tool.
2.
Click 3 times to show on the display
window (Figure
C
5
).
3.
Aim the laser at the top of the tool (Figure
A
1
)
at the highest point of the building or object whose
height you need to measure (Figure
G
#1).
4.
Click to measure the distance to the top of the
tall object.
5.
From the same point, aim the laser at the lowest
point of the building or object (Figure
G
#2).
6.
Click to measure the distance.
7.
On the bottom line of the display window, view the
height of the building or object.
Using the Distances to 3 Points
1.
Click (Figure
A
3
) to turn on the tool.
2.
Click 4 times to show on the display window
(Figure
C
5
).
3.
Point the laser (Figure
A
1
) at the highest point
of the building or object whose height you need to
measure (Figure
H
#1).
4.
Click to measure the distance to the top of the
tall object.
5.
From the same point, aim the laser on a horizontal
line straight ahead toward the building or object
(Figure
H
#2).
6.
Click to measure the distance.
7.
From the same point, aim the laser at the lowest
point of the building or object (Figure
H
#3).
8.
Click to measure the distance.
9.
On the bottom line of the display window, view the
height of the building or object.
Adding Measurements
You can add two measurements to get a total
measurement of the two distances.
1.
Point the tool's laser (Figure
A
1
) toward a wall or
object, and not toward anyone's eyes.
2.
Click (Figure
A
3
) to turn the tool on.
3.
By default, distances are measured from the bottom
of the tool to a wall or object (Figure
E
3
).
To measure distances from the top or middle of the
tool, or from the tool's endpiece (when it is flipped
open to measure from a corner), click
.
4.
Click .
5.
Click .
6.
Select + to indicate that you want to add
measurements.
7.
Point the tool's laser toward the wall or object whose
distance you need to measure.
8.
Click to measure the distance from the tool to the
wall or object.
9.
Point the tool's laser toward the next wall or object.
10.
Click to measure the distance and add it to the
previous measurement.
11.
View the total of the two measurements at the bottom
of the display window (Figure
C
6
).
Subtracting Measurements
You can subtract one measurement from another.
1.
Point the tool's laser (Figure
A
1
) toward a wall or
object, and not toward anyone's eyes.
2.
Click (Figure
A
3
) to turn the tool on.
