[Job] [Settings] [Level]
The Level Setting screen is only available when running in leveling mode. It is used to configure all of the settings for
performing a level loop.
BS1…BSn>FS1…FSn : This sequence requires that you take all the shots for each set to the backsight, turn to the
foresight, and then shoot all the shots for each set to the foresight.
[BS1 FS1>FS2 BS2]n: A single set in this sequence requires that you shoot the backsight, turn and shoot the foresight,
shoot the foresight again, turn and shoot the backsight. Repeat for all remaining sets.
Number of Sets (n): The number of sets you want to shoot from each setup.
Stadia Constant: The scale of the upper and lower stadia (wires) in the telescope. The vertical distance measured
between these stadia multiplied by the value entered here (usually 100) equals the horizontal distance to the rod.
V Dist Tolerance: The maximum change in vertical distance that can occur between all the shots to any specific point
from a single setup. If this value is exceeded, a warning will occur.
H Dist Tolerance: The maximum change in horizontal distance that can occur between all the shots to any specific
point from a single setup. If this value is exceeded, a warning will occur.
BS-FS Sight Length < Per Shot: When checked, a warning will occur whenever the horizontal distance of each leg in
any given setup differs by more than this value.
BS-FS Sight Length < Per Loop: When checked, the sum of the horizontal distances measured to all the backsight
shots are compared to the sum of the horizontal distances to all the foresight shots. If the difference exceeds this value,
a warning will occur.
Max Sight Lengths: When checked, a warning will occur whenever the horizontal distance measured to any point
exceeds this value.
Min Ground Clearance: When checked, a warning will occur if a shot is taken at a location on the rod that is within
this distance to the ground.
Max Loop Misclosure: When checked, the error computed after a level loop is closed will be surrounded with
exclamation points in the Close Loop screen and Level Notes screen if the error exceeds this value.
Upper-Lower Wire Reading <: When checked a warning will occur if the difference between the upper stadia and
crosshair exceeds the difference between the crosshair and lower stadia by this value. (This only applies to the Three
Wire level method.)
[Load FGCS Defaults]: Opens the FGCS Defaults screen, described below, where the default tolerances for a
specified level loop order and class can be loaded.
FGCS Defaults
[Job] [Settings] [Level] [Load FGCS Defaults]
The FGCS Defaults screen is used to load the default FGCS tolerances in the Level Settings screen for the order and
class of level loop specified here.
Order: Indicates the order of the level loop that you want to load the default tolerances for.
