3. Press On to display the width
measurement at the top of the
display window.
View the Area measurement at the bottom of
the display window (Figure E
3
).
Measuring Volume
You can measure the volume of a room
or object.
1. Press the gear button (Figure A 4 ) three
times to show the indirect measurement
height on the display window
(Figure E
3 ).
Measure the width.
1. Point the top of the tool at one side of the
target (room or object).
2. Position the tool at one end of the target
and point the laser dot across the width.
(Figure H
1
) shows where to position the
tool if you are measuring from the top of
the tool.)
3. Press to display the width measurement at
the top of the display window.
Measure the length.
1. Position the tool at one end of the target
and point the laser dot across the length.
(Figure H
2
) shows where to position the
tool if you are measuring from the top of
the tool.)
2. Press On to display the length
measurement on the second line of the
display window.
Measure the height.
1. Positon the tool at one end of the target
and point the laser dot across the height.
2. Press On to display the height
measurement on the third line of the
display window.
View the Volume measurement at the bottom
of the display window (Figure C
3
).
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
(A2+B2=C2) to calculate the height.
Measure a distance with two
measurements
You can use the distance to two points on a
tall object (Indirect Height) to determine its
height (Figure I1).
1. Point the tool's laser (Figure A
1
)
toward a wall or object, and not toward
anyone's eyes.
2. Press On button (Figure A
3
) to turn the
tool on and display the red laser dot.
3. Press the gear button (Figure A
4
) three
times to show pythagoras (Figure B
1
) on
the display window.
4. Position the tool opposite the bottom of
the building or object whose height you
need to measure (Figure I2).
5. Aim the laser at the highest point of the
building or object (Figure I2).
6. Press On button (Figure A 3 ) to measure
the distance.
7. From the same point, aim the laser
straight ahead toward the lowest point of
the building or object (Figure I3).
8. Press On button (Figure A
3
) to measure
the distance.
9. On the bottom line of the screen, view the
height of the building or object.
Measure a distance with three
measurements
You can use the distance to three points on a
tall object to determine its height (Figure J1).
