================= MAIN FEATURES ~=============
-GT8-38 (GT8-3C) is a tachometer which is provided with electronic angle reading and dis-
tance measuring functions. GT8-38 covers 5 second reading electronic angle measurement
tance measurement up to 2.5 km.
GT8-3C is provided with electronic angle reading by 10 sec-
onds and distance measurement up
to 1.8 km. The data obtained .can be stored electronically
through TOPCON's FC-1 Data Collector. The GT8-38 (GT8-3C) has been developed as an elec-
tronic total station suitable for use in field surveying as well as a key component in acomputerized
surveying system.
-The unit of angle measurement is changed by operating option switches; 1 second reading is
available with GT8-38'with 5 second divisions. 10 second reading is available with GT8-3C with
5 second divisions.
-Horizontal angles, vertical angles, slope distances, horizontal distance,' relat-ive'elevation,
coordinates of an unknown point and elevation are all available by using the GT8-3'8 (GT8-3C).
The measurements and displayed through a liquid crystal display and can be transmitted and
stored
in TOPCON's FC-1 Data Collector.
-Angle measurement is obtained by the incremental method. The
"0" position of the vertical
angle
is easily obtained.
-A built-in high-precision tilt sensor (liquid compensator) is used for the vertical axis correction.
The "0" position of the vertical angle is easily set and a relative elevation measurement is
possible with high accuracy.
-The excellent features of the GT8-38 (GT8-3C) will produce high accuracy and excellent
efficiency when used properly during a survey.
-Various points in a detailed survey are immediately available by measuring ,the angle and
distance from
an occupied station. The data can be applied effectively, for instance, by
transforming it to a
graphic expression by use of a computer system or directly used for
computation
in design.
-The data can be used effectively for peg checking, reference, re-construction and distance
measurement
in engineering surveys.
-Through TOPCON's technology, we have succeeded in building a compact, light-weight total
station (5.2 kg), with our end users being the benefactors.
-It is possible to connect the GT8-38 (GT8-3C) with a computer by using serial signal R8-232C
connector.

Accuracy around the far end of measuring distance is enhanced by adding the number of
prism; higher accuracy is available with 3 prisms than that with a single prism and with
9 prisms higher accuracy
is available thafl that with 3 prisms.
