H Dist Tolerance: is 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.)

below, where the default tolerances for a specified level loop order
and class can be loaded.
