Digital Theodolite
The term digital theodolite can be used to
describe those survey instruments designed to precisely measure horizontal and
vertical angles. In addition to measuring horizontal and vertical angles,
digital theodolite are used to establish straight lines, to establish
horizontal and vertical distances through the use of stadia, and to establish
elevations when used as a level.

A digital theodolite is a survey instrument
using a three-screw leveling base, glass horizontal and vertical circles read
directly with a digital display, and equipped with right-angle optical plummet
for setting over specific points.

The digital theodolite consists of three main
assemblies. The upper assembly, called the alidade, includes the
standards, telescope, digital display for reading the horizontal and vertical
circle, plate bubbles, compass, and upper tangent (slow motion) screw.

The spindle of the alidade on the digital
theodolite fits down into the hollow spindle of the next assembly, the circle
assembly. The circle assembly includes the horizontal circle that is
covered by the alidade plate , the upper clamp screw, and the hollow spindle
previously mentioned.

The hollow spindle of the circle assembly on
the digital theodolite fits down into the leveling head, the final assembly of
the digital theodolite. The leveling head on the digital theodolite
includes the four leveling screws, the half-ball joint about which opposing
screws are manipulated to level the digital theodolite instrument, a threaded
collar that permits attachment of the digital theodolite to a tripod, the lower
clamp and slow-motion screw.

How to
Use a Digital Theodolite Step-by-step
Use a Digital Theodolite Step-by-step
1. Set up

2. Back
sight your digital theodolite survey instrument by sighting the crosshairs and
focusing telescope and on a reference point. The reference point can be
occupied by a pole at least 150 feet away.
