Upgradable to perform as a 'total
station'
Topcon's digital theodolite DT-101 is integrated into the latest technology
in both the electronic and optics. In addition to its high accurate angle
measurement ability, the DT-101 allows you to form the most reasonable
'total station system' combined use with various kinds of Topcon electronic
distance meters.
Highly accurate angle measurements
Due to its 2 sided detecting system for both horizontal and vertical
angle readings, Topcon's DT-101 can assure highly accurate angle measurement
of 2" (0.6mgon) in the standard deviation based on DIN 18723.
EDM communication
The DT-101 is designed to combine various models of Topcon EDM's,
which means the most reasonable 'total station system' is possible due
to its EDM communication capability.
Data output
The DT-101's RS-232C serial signal port provides the capability of
communicating to a data collector or computer.
Automatic
vertical compensation
A tilt sensor for the vertical angle correction assures high precision
measurement accuracy. The correction range is ±3'.
Coaxial vertical axis design
Equipped with a coaxial vertical axis design, the DT-101 can reduce
much of the graduation errors in repeating angle measurements. That
will help to obtain precise surveying results.
Other features:
Coaxial tangent and clamp crews
- Compact and light weight
- Simple operation
- Measuring horizontal angles right and
left
- Horizontal zero set
- Built-in battery pack
- Automatic power off (after 10 or 30
minutes)
- Self-check
- Water resistant sealed construction
