Single level runs downward, from Floor N-1 to Floor 1, the upward leveling deviation is
recoded as Dn(N-1),...Dn(2),Dn(1)
Calculate the current leveling position error of each floor
X(2) = (Up(2) + Dn(2)) / 2;
X(3) = (Up(3) + Dn(3)) / 2;
X(4) = (Up(4) + Dn(4)) / 2;
...
...
X (N-1) = (Up (N-1) + Dn (N-1)) / 2;
If the deviation of X(2)～X(N-1) exceeds 10 mm, please adjust spile , a positive X(n) means
the spile of this floor is too high; a negative X(n) means the spile of this floor is too low. If
the deviation is less than 10mm, adjust with leveling fine-tuning software.
After rough adjustment for spile, carry out well self study again, and record leveling data.
Single level runs upward, from Floor 2 to Floor N, the upward leveling deviation is recoded as
Up(2),Up(3), ... Up(N)
Single level runs downward, from Floor N-1 to Floor 1, the upward leveling deviation is
recoded as Dn(N-1),...Dn(2),Dn(1)
1) Calculate the current leveling position error of each floor
X(2) = (Up(2) + Dn(2)) / 2;
X(3) = (Up(3) + Dn(3)) / 2;
X(4) = (Up(4) + Dn(4)) / 2;
...
...
X(N-1) = (Up(N-1) + Dn(N-1)) / 2;
2) Calculate the current average offset XUp, XDn; end station is not included
Upward average offset XUp = (Up(2) + Up(3) + ... + Up(N-1)) / (N-2);
Downward average offset XDn = (Dn(2) + Dn(3) + ... + Dn(N-1)) / (N-2);
Central position pX = (XUp - XDn) / 2;
Note: XUp, XDn, pX are operations with symbols
3) Adjust F56, F57:
F56 = 50 - pX;
F57 = 50 - pX;
4) Adjust leveling fine-tuning, record the leveling fine-tuning data of the Nth floor to Ln
L(2) = 20 - X(2)
L(3) = 20 - X(3)
...
L(n) = 20 - X(n)
...
L(N-1) = 20 - X(N-1)
Calculate the leveling fine-tuning of the end station
◆ Reasons why leveling cannot be adjusted:
There may be the following questions, please check in order:
1．The following parameters will lead to improper leveling adjustment if not reasonably
configured
