After the total station is leveled, lock the eyepiece and rotate horizontally to the vertical angle

1. Vertical angle movement, this problem is normal, indicating that there is no problem with your instrument.

2. After opening the compensator, moving the vertical angle is the compensation adjustment process of your instrument "not very flat", indicating that the compensation function has worked. The instrumentation is good.

3. If the vertical angle does not change when opening and closing the compensator, it means that there is a problem with your instrument, the compensator has failed, and the measured vertical angle will also have problems.

4. What you lock is the eyepiece, it is the telescope, the compensator is open and closed, the telescope is not moving, but your vertical disk is moving, so there is a change in the vertical angle. In fact, the function of the compensator is to adjust the vertical plate to the correct position.

You are right, not the reason for the same, open the compensation, the angular value changes normally, theoretically rotate the alignment part, the vertical angle will not change, in practical application, the instrument is not strictly leveling, there is a leveling error, when the alignment part rotates, the compensator will change, and the vertical angle will change with the change

As long as it is a biaxial compensation instrument, this is caused by the instrument does not level the influence of the tilt of the instrument on the horizontal angle, δHz = a cot z where hz is the horizontal dial reading, z is the zenith distance, a is the amount of transverse axis inclination, you can see that the change of the horizontal angle is related to the size of the vertical angle. Therefore, when calibrating a straight line with a total station, you need to pay attention to the change in the horizontal angle.

It shouldn't change, if your instrument is not leveled or the vertical axis is not vertical, it will change, then it is an operation or a problem.

It can't change, it's sure that you don't have a good leveling, and compensation is to compensate for the part you didn't level.

Theoretically, it won't change anymore, maybe you didn't do the leveling, or there is a problem with the total station itself.

Theoretically, it won't move, is it a bit of a problem with vertical braking, or is it that the braking is not tight.

10''The inside are very normal. Many of the above explanations are very correct! If you don't know very well, don't be sure of your answer to mislead everyone!!

It can be adjusted by using a total station or theodolite, the specific method:

Set up the total station or warp and weft instrument and level it accurately. Use a tripod to support the prism rod at a distance of 20m (the distance can be set by yourself).

Use the total station or theodolite vertical wire to illuminate the tip of the prism rod and lock the total station or theodolite for horizontal braking. Turn the telescope vertically from the tip of the prism to the prism crosswire position. (At this time, the prism rod is not perpendicular, and there is a gap between the illumination position and the crosswire position).

At this point, one person observes the instrument and directs the other person to adjust the prism tip to the vertical position with the prism crosswire (regardless of whether the bubble on the prism rod is centered or not). After adjustment, the prism rod bubble will not be centered, then fix the prism rod and use the calibration needle to adjust the bubble to the middle. (After adjustment, it is recommended to turn the prism rod to a position of 90° from the original position, and then adjust it again according to the above steps).

If the prism rod is bent, as long as the prism tip and the prism cross wire are in a straight line.

The tripod leveling methods and skills of engineering surveying and mapping total stations and prisms will not be learned!

You're talking about the prism rod, you have to use the total station, one person to see, one person to adjust the bubbles, just stand the prism rod about 10 meters to see clearly, use the total station to the prism rod foot, and then look up at the prism wire, command the left and right deviations of the bubbles to align with the total station cross, and then adjust the prism rod bubbles, the prism rod turns 90 degrees, and repeats the previous steps.

To do control, you still need distance, do not use a prism for control, and put the prism on the ground for distance.

Use two laser markers, place them at 90 degrees, and hit the line directly on the pole. You're welcome.
