Xingruida Total Station Keyboard Instructions

Laptop keyboard key failure is usually caused by software or hardware failure. You can follow these steps to troubleshoot: 1. Restart the notebook to see if that solves the problem. 2. Check whether there is dust or debris on the keyboard, and clean the keyboard. 3. Connect the external keyboard and confirm whether there is a hardware failure. 4. Check whether the keyboard driver in the device manager is normal. 5. Update or reinstall the keyboard driver. If the problem persists, it is recommended that you contact an after-sales or repair center for further diagnosis and repair.

1. When the SAMSUNG icon appears when the computer is turned on, press the F2 key to enter the BIOS settings, press the F9 key to restore the BIOS to factory mode, and press F10 to save and restart.

2. Use a U disk or CD to boot into PE or Dos mode to confirm whether it is available.

3. Before the system icon appears when you turn on the computer, quickly press the F8 key to enter safe mode and try to confirm whether it is caused by a system or software failure.

Check whether there is any foreign matter under the buttons. If there is any, please turn the machine upside down or gently shake it. You can also use brushes, tweezers, air blowers and other tools to simply remove it (you need to be careful not to damage the bracket under the buttons. Non-professionals should operate with caution to avoid more serious damage). If the problem is serious, please send the machine to the after-sales service center for cleaning and repair by professional engineers.

Please confirm whether the keyboard has been exposed to liquid and whether the keys can spring up normally. If there is liquid entering the keyboard or the keys cannot pop up normally, it is recommended that you go to the after-sales service center and let the engineers help you with further inspection and repair.

6. Try reinstalling the operating system (you are prompted to back up important data and information first).

7. If you need temporary use, you can also connect a USB keyboard for use.

Instructions for use of total station

First of all, about the explanation of the above language: the total station automatically calculates the north coordinate of the measuring point based on the input data. By inputting the three-dimensional coordinates of the measuring point, the coordinates of the backsight point and the azimuth angle, a known straight line can be determined. The direction of the line is also known. For example, when the azimuth angle is 90 degrees, the direction the total station points to after turning 90 degrees is north (or possibly south, but this does not need to be considered).

Secondly, I don’t know much about earthwork surveying. The following opinions are for reference only. I think it is similar to ordinary surveying. Although there are no known coordinates, you can set them yourself, such as an inflection point or a vertex of a polygon. You can set its coordinates to (500,500), preferably not (0,0), for fear of negative numbers. As for the elevation, you can also set it as usual, and then the coordinates of other points will be based on this point!

Finally, you said that the north direction is different every time you measure it. That’s because your measuring station setting is wrong or not set at all. Let me give you a simple example. You want to measure the terrain and features in a square area. Square The three dimensions of the four vertices are known (the azimuth angle is also known), and the measuring station is set at the vertex (convenient and accurate). Some features need to change stations due to the field of view. Then, you need to enter the location when you go to another station. Point coordinates, instrument height, coordinates of the backsight point, and aim at the backsight point, and set the instrument horizontal plate to read as its azimuth, so that the north direction you mentioned will not appear again!

I don’t know if you understand it. If you don’t understand, ask me again. I am a rookie in earthwork surveying. If you ask me, I don’t know!
