Description :
Specific steps:
1: We need to take the opposite direction of the known point as the forward direction, place a level between the measuring station and the known point, pay attention to keeping the distance as equal as possible, and then roughly level the level.
2: Rear view leveling ruler, precision leveling, reading, record in the table (note: both points need to be operated as above), to facilitate the calculation of the height difference of the station.
3: Repeatedly adjust the height of the instrument, repeat the second operation, and the height difference between the two times should not exceed 5mm.
4: Start the second station and repeat all the above operations.
5: Calculate the closure error of the leveling line based on the elevation of known points and the height difference of each measuring station. (Note: Check if the closure error exceeds the limit)
Notes:
1: We need to clarify the data of each station and avoid confusion that may lead to errors.
2: The level ruler must be set on the benchmark and cannot be directly placed on the ground.
3: Each station needs to adjust the height measurement of the instrument at least twice.
4: When leveling, first close the tripod and align their lengths, then place it on the flat bottom. The telescope should be at the same height as the line of sight, and observe the circular level to ensure that the bubble is in the center.
5: When leveling, use a micro tilt spiral to observe the outside to inside of the long level, and adjust it continuously when observing long bubbles.
6: To eliminate parallax, it is necessary to strictly align the level bubbles before taking readings.
