The STS-720 series is 2013 for sanding photoelectric series electronictachometer professional engineering survey launched.
Non prism measurement 600m, single prism 5000m, ranging accuracy 2+2ppm.
Selection of measurement procedures simplified, IP55 level against solid firm body, as measured by engineering design.
Absolute encoding angle measurement, laser reflectorless, guarantee the speed and accuracy of measurement.
STS-720 series of ultra high performance configuration, build measuring instrument model practical and easy to use and convenient.Feature:
First, the absolute angle encoding
Two, reflectorless laser
Three, laser pointer
Four, biaxial liquid photoelectric electronic compensation
Five, laser alignment
Six, IP56 waterproof and dustproof design
Seven, large memory
Eight, convenient communication mode
Nine, big screen, big button
Ten, the screw pitch is changed from 0.35MM to 0.25MM -- fine amplitude encryption, more accurate alignment of the eyepiece.
Simple measurement procedures
Setting out point data can be described by field input, you can also call the total station data memory. Memory data can be stored in the total station and through computer upload. But you can see the polar coordinates, and orthogonal coordinate difference lofting deviation.
The program can calculate the real-time 2 target points between the oblique distance, horizontal distance and elevation and azimuth. In the calculation of points can be measured in real time or selected from memory, can also be manually entered from the keyboard. The user can have the line of the edge and the edge ray on the two choices. In the measurement process, the last two points of the edge of the instant can check.
Area measurement program can area and perimeter surrounded by the connection between real time measurement target. No limit of the target points involved in the calculation of points can be measured in real time, selected from memory, but also from the keyboard input field.
Some prism can not reach the point to be measured can be directly targeting is below the reference point on the prism, leveling measurement distance, then aim hanging high, measure the height difference of the point to be measured. The clearance can be used for measuring high voltage lines, bridges and other structures of the high.
The design and layout of the road
Plane and elevation design values of four types of elements, which can be edited by straight line, arc, transition curve and intersection point. The road layout function can be conveniently according to the road mileage to determine the position of pile, side pile and slope boundary.
After the prism is unable to reach or obstacle position, it can calculate the coordinates of the point of view which can not reach the point of view through the relative relations, such as angle and distance by observing its adjacent visual point. Eccentric measurement includes eccentric distance and eccentric angle.
At the fixed point on the station, the three known control points to the two levels of a, B, which calculate the coordinates of the point to be fixed, known as the rear intersection. It can be located in several known control points, respectively, to be fixed point observation direction or distance, can also be set up to the point of a number of known control points to the observation direction or distance, and then calculate the coordinates of the fixed point.
