(2) setting the reading of a horizontal dial in the direction A to be 0 degrees 00';
(3) the second target B is aimed at, and the horizontal scale reading displayed at this time is the horizontal angle between the two directions.
Distance measurement
(1) Setting prism constant
The prism constant is input into the instrument before the distance measurement, and the instrument automatically corrects the measured distance.
(2) Setting atmospheric correction value or air temperature and air pressure value
The propagation speed of light in the atmosphere varies depending on the temperature and pressure of the atmosphere, and 15 ℃ and 760mmHg are standard values set by the apparatus, at which the atmosphere is corrected to 0 ppm. In actual measurement, temperature and air pressure values can be input, the total station can automatically calculate an atmosphere correction value (or directly input the atmosphere correction value), and a distance measurement result is corrected.
(3) The height of the measuring instrument and the height of the prism are input into the total station.
(4) Distance measurement
Aiming at the center of the target prism, pressing a distance measurement key, starting distance measurement, and displaying slant distance, horizontal distance and height difference when the distance measurement is completed.
The distance measuring mode of the total station comprises a precise measuring mode, a tracking mode and a rough measuring mode. The precision measurement mode is the most common distance measurement mode, the measurement time is about 2.5S, and the minimum display unit is 1 mm; a tracking mode, which is usually used for continuous distance measurement when a moving target is tracked or lofting is performed, wherein the minimum display is generally 1cm, and the time for each distance measurement is about 0.3S; rough measurement mode, measurement time of about 0.7S, minimum display unit of 1cm or 1 mm. In the case of distance measurement or coordinate measurement, a different distance measurement MODE may be selected by pressing a distance measurement MODE (MODE) key.
It should be noted that some types of total stations cannot set the instrument height and the prism height during distance measurement, and the displayed height difference value is the height difference between the center of the transverse axis of the total station and the center of the prism.
Coordinate measurement
(1) And setting the three-dimensional coordinates of the station.
(2) The coordinates of the back-view point or the horizontal scale reading of the back-view direction are set to its azimuth angle. When the coordinates of the back-view point are set, the total station automatically calculates the azimuth angle of the back-view direction and sets the horizontal dial reading of the back-view direction as the azimuth angle.
(3) The prism constant is set.
(4) Setting the atmospheric correction value or the air temperature and air pressure value.
(5) The height of the measuring instrument and the height of the prism are input into the total station.
(6) And (4) aiming at the target prism, pressing a coordinate measuring key, and starting distance measurement and calculating and displaying the three-dimensional coordinates of the measuring point by the total station.
