Introduction
An Automatic Level is a professional leveling tool used by
contractors, builders, land surveing professionals, or the
engineers who demands accurate leveling every time. Auto
levels set up fast, are easy to use, and save time and money
on every job. Some auto levels come in kits that include the
grade rod and tripod. Auto levels are great for fence
builders, foundation installer, excavations, deck builders,
landscaping pros, swimming pol builders, home builders,
roadwork jobs, ... etc.
In order to do the job properly, be it setting a line for laying
concrete blocks, or setting the grade on a driveway or farm
road, the right auto level must be chosen. Be sure to
understand what the job is and what the different levels can
do.
There are different types of automatic levels, each one
designed for a specific job type:

Uses
Dumpy level General survey work such as setting property
lines; laying out highways, power lines, and
other large area construction where horizontal
measurements are essential.

level
Good for most general survey work, as well as
setting horizontal markers for masonary work,
such as brick and block laying; useful in setting
foundations and installing subflooring in
residental and industural construction.
Laser level Most useful when laying out foundations;
masonary work; other jobs where a 360 degree
reference line is needed.
Digital level Useful for general survey and most
construction projects but with the added

benefit of more precise data collection and the
ability to record.

level
The choice of carpenters, handymen, weekend
warriors, and tinkerers of all sorts, great for
small projects like hanging shelves and picture,
and professional jobs like mounting
thermostats, electrical receptacles, and light
switches.
Equipments
List of equipments and tools need to completing the test:
 Automatic level
 Tripod
 Staff
Procedure
Steps and instructions to set up an automatic level and
measuring horizontal distances:
1. Setup tripod as level as possible, step on tripod legs to
drive into the ground.
2. Attach auto level to the tripod.
3. Adjust level so bubble is centered in vial.
4. Adjust resital util crosshairs are clear.
5. Adjust the objective lense until object you are sighting
on is clear.
6. Select two points (A and B) to measuring the distance
between them.
7. Place the auto level over point A and the staff over
point B. Take the reading.
8. Shift the instrument (auto level and tripod) to point B
and staff to point A, and take the reading again.

9. The distance between two points (at there A and B) can
be determind by this equation:
(Upper reading – Lower reading) × 100 = Distance
between A and B
Calculation
Reading
Upper 133.1
Lower 122.8
Result and Conclusion
Using an automatic level can improve the accuracy needed
when grading a roadway or setting the foundationof an new
home. Just as important to the individual, automatic levels
can make doing smaller jobs better, such as hanging
pictures, shelving, and shower curtain rods.
From the data of previous table the result can be determine,
by this equation:
Distance between A and B = (133.1− 122.8) × 100 = 1030 𝑐𝑚
