Where is the temperature setting of total station?

The functions and usage of total station are as follows:

Total station has many uses, such as angle measurement, distance measurement, three-dimensional coordinate measurement, traverse measurement, intersection point fixed point measurement, lofting measurement and so on. With the built-in dedicated software, its functions can be further expanded.

Basic operation and usage of total station;

1, horizontal angle measurement

(1) Press the angle measurement key to make the total station in the angle measurement mode and aim at the first target A. ..

(2) Set the reading of the horizontal dial in direction A to 0 00' 00 ".

(3) Aim at the second target B, and the horizontal dial reading displayed at this time is the horizontal included angle between the two directions.

2. Distance measurement

Aim at the center of the target prism, press the ranging key to start ranging, and display the oblique distance, horizontal distance and height difference after ranging.

There are three ranging modes of total station: precise measurement mode, tracking mode and coarse measurement mode. Precision measurement mode is the most commonly used ranging mode, with a measurement time of about 2.5S and a minimum display unit of1mm.

3, coordinate measurement

(1) Set the 3D coordinates of the station number.

(2) Set the coordinates of the rear viewpoint or set the horizontal dial reading in the direction of the rear viewpoint as its azimuth. When setting the coordinates of the rear viewpoint, the total station will automatically calculate the azimuth of the rear viewpoint direction, and set the horizontal dial reading of the rear viewpoint direction as its azimuth.

(3) Set the prism constant.

(4) setting atmospheric correction value or air temperature and pressure value.

(5) The measuring instrument is high and the prism is high, so input the total station.

(6) aim at the target prism, press the coordinate measuring key, and the total station will start to measure the distance and calculate the three-dimensional coordinates of the measuring point.

4, total station leveling and bubble correction method to level the instrument correctly:

(1) Erection: Erect the instrument on a stable tripod and tighten the central screw.

(2) Rough leveling: Look at the circular bubble (the accuracy is relatively low, generally 1 min), and rotate the three foot screws of the instrument respectively to roughly level the instrument.

(3) Fine leveling: make the tubular level (or long bubble tube) on the sighting part of the instrument parallel to any pair of foot screws, and rotate the foot screws to center the bubble (it is best to use the left thumb method, that is, the left and right hands rotate the two foot screws at the same time, and the two thumbs move in opposite directions, and the direction of the left thumb is the same as that of the bubble tube. ); Then, rotate the aiming part by 90 degrees, and rotate the other foot screw to center the bubble in the long bubble tube.

(4) Inspection: rotate the aiming part of the instrument for another 90 degrees. If the bubble in the long bubble tube is still in the center, it means that it has been leveled; If there is any deviation, please repeat step (3). In general, it is good to repeat 1 ~ 2 times.

Preservation method of extended data total station

1, someone will be responsible for the custody of the instrument and bring it back to the office after it is used on site every day; Don't put it in the toolbox.

2. The instrument box should be kept dry, moisture-proof and waterproof, and the desiccant should be replaced in time. The instrument must be placed on a special shelf or in a fixed position.

3. When the instrument is not used for a long time, it should be taken out regularly in January to prevent mildew, and the instrument should be electrified to drive away the tide, so as to keep the instrument in good working condition.

4, the instrument should be neat, not upside down.
