How to check the total station and how often the total station is calibrated

You have to say which brand of instrument and model.

The total station is calibrated every year, and the total station testing center that has been verified and calibrated will issue a verification certificate, which is pasted on the body of the total station, and the verification and calibration date is indicated on the certificate.

The leveling axis of the alignment part should be perpendicular to the vertical axis of the parallel and closed inspection and correction inspection, first the instrument is roughly leveled, rotate the alignment part to make its leveling tube parallel to the line of any two foot spirals, adjust the foot spiral to center the bubble, and then rotate the alignment part 180 degrees, if the forest shielding bubble is still centered in this state, it means that the conditions are met, otherwise the correction should be carried out.

The purpose of the correction is to make the horizontal tube axis perpendicular to the vertical axis. That is, use the correction needle to dial the correction screw at one end of the leveling tube to make the bubble retreat half to the middle position. In order to make the vertical axis upright, the bubble can be centered with a foot spiral This inspection and correction must be repeated until the conditions are met.

Summary. Total station related problems: Hello dear, your situation should be something wrong with the instrument's program. As we all know, the value range of the azimuth angle is [0,360], you ** in the hr display number, itself is not normal, DHR is the difference between the current line of sight azimuth and the azimuth angle to be staked, so the value range will not be greater than 360 degrees, so this is a problem with the instrument itself.

The total station is an electronic product, built-in calculation program system, so there is a certain probability of failure, in this case, it is recommended to shut down and restart first, to see if the fault is eliminated, it is really not possible to remove the battery and reinstall it. If the fault persists or the same fault occurs frequently, then it is time to find a professional repairman to repair it.

Excuse me, my origin a is high is 0It is known that the point B is high at 50I measured the point between ab and cWhether the height of point c is relative to the origin 0 or the height above the diagonal line of the coordinate system 0 to 50.

Question] In order to measure the height of building AB, starting from point C (point C is on the same level as floor B) 50 meters away from the bottom of building B, advance 20 meters along the slope CD with an inclination angle of 30° to point D, measure the elevation angle of building A at point D is 64°, and find the height of building AB (the result is accurate to 1 meter) (reference data: sin64°, cos64°, tan64°, answer】The height of building AB is about 79 meters [Analysis] Test question analysis: in RT In CDN, bm=dn=cd=10, cn=cdcos c=10, that is, dm=bn=50 10, according to ab=bm+am=bm+dmtan adn, the answer can be obtained Test problem analysis: in RT CDN, cd=20m, c=30°, BM=dn=cd=10m, cn=cdcos c=20=10m, bc=50m, dm=bn=bc cn=50 10, in rt adn, by tan adn= am=dmtan adn=(50 10)tan64°, then ab=am+bm=(50 10)tan64°+10 79 meters, A:

The height of the building is about 79 meters

1) Horizontal angle measurement.

1) Press the angle measurement button to put the total station in angle measurement mode and aim at the first target A.

2) Set the horizontal dial reading in the A direction to 0°00 00.

3) Aiming at the second target b, the horizontal dial reading displayed at this time is the horizontal angle between the two directions.

2) Distance measurement.

1) Before setting the prismatic constant ranging, the prism constant must be input into the instrument, and the instrument will automatically correct the measured distance.

2) Set the atmospheric correction value or air temperature and air pressure value, the propagation speed of light in the atmosphere will vary with the temperature and pressure of the atmosphere, 15 and 760mmHg is a standard value set by the instrument, and the atmospheric correction at this time is 0ppm. During the actual measurement, the temperature and pressure values can be entered, and the total station will automatically calculate the atmospheric correction value (or directly enter the atmospheric correction value), and correct the ranging results.

3) The measuring instrument is high, the prism is high, and the total station is inputted.

4) The distance measurement is aimed at the center of the target prism, press the ranging button, the distance measurement starts, and the oblique distance, flat distance and height difference are displayed when the distance measurement is completed. There are three types of ranging modes of the total station: precision measurement mode, tracking mode and rough measurement mode. The precision measurement mode is the most commonly used ranging mode, the measurement time is about, and the minimum display unit is 1mm; Tracking mode, often used for continuous ranging when tracking moving targets or lofting, the minimum display is generally 1cm, and the time of each ranging is about; Coarse measurement mode, measurement time approximately, the minimum display unit is 1cm or 1mm.

When measuring distances or coordinates, you can press the Mode button to select different ranging modes. It should be noted that some models of total stations cannot set the height of the instrument and the height of the prism when measuring the distance, and the height difference displayed is the height difference between the center of the horizontal axis of the total station and the center of the prism.

3) Coordinate measurement.

1) Set the 3D coordinates of the measuring station.

2) Set the coordinates of the backsight point or set the horizontal dial reading of the backsight direction as its azimuth. When setting the coordinates of the backsight point, the total station automatically calculates the azimuth of the backsight direction and sets the horizontal dial reading of the backsight direction to its azimuth.

3) Set the prism constant.

4) Set the atmospheric correction value or air temperature and pressure value.

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

6) Illuminate the target prism, press the coordinate measurement button, and the total station will start the ranging and calculate the three-dimensional coordinates of the display measurement point.

Did you buy it in **? We teach our customers how to use it, and Shanwei Haifeng has a physical store.

Can anyone tell me what the total station is used as a telescope, what its main function is, to measure angles, distances, what to do???

What model of total station? Just give you the manual, and it's over.

According to the national requirements, it is necessary to do annual inspection, but some places do not do annual inspection if the requirements are not strict. If you want to do the annual inspection, you can go to the department with the qualification of measuring instrument verification to verify, or you can send it to the local instrument dealer to verify on your behalf. However, regardless of whether it is verified or not, the accuracy of the measuring instrument must be guaranteed.

The total station, that is, the electronic total station, is a high-tech measuring instrument integrating light, machinery and electricity, and is a surveying and mapping instrument system integrating horizontal angle, vertical angle, distance (oblique distance, flat distance) and height difference measurement functions. Compared with the optical theodolite, the electronic theodolite replaces the optical dial with a photoelectric scanning dial, and replaces the artificial optical micrometer readings with automatic recording and display of the readings, which simplifies the operation of angle measurement and avoids the generation of reading errors. Because it can complete all the measurement work on the station by placing the instrument at one time, it is called a total station.

It is widely used in the field of precision engineering measurement or deformation monitoring such as large-scale above-ground buildings and underground tunnel construction.

The difference between a total station and an optical theodolite is the dial reading and display system, and the horizontal and vertical dials of the electronic theodolite and their reading devices are respectively measured by (coding discs) or two identical grating dials and reading sensors. According to the accuracy of angle measurement, it can be divided into several grades,,, 1, 2, 5 and so on.

There are professional places responsible for testing and verification, and we are inspecting and calibrating in the city's surveying and mapping institute, what bureau, and then paste a certificate for you, which inspector is. It's all about the process.
