Field Description
Segm Segment number. Includes the misclosure segment, if applicable.
CumL Cumulation of the segment lengths. Changes with the current number of segments.
Includes the misclosure segment length if applicable.
dH.A. Horizontal direction from the measured point to the setout point. Positive if the tele-
scope must be turned clockwise to the setout point.
d.H.D. Horizontal distance from the measured point to the setout point. Positive if the setout
point is further away than the measured point.
d.d.z. Height difference from the measured point to the setout point. Positive if the setout
point is higher than the measured point.
dL Longitudinal distance from the measured point to the setout point. Positive if setout
point is further away than the measured point.
dO Perpendicular distance from the measured point to the setout point. Positive if setout
point is to the right of the measured point.
Messages Description
Baseline too short! Base line is shorter than 1 cm. Choose base points such that the horizontal
separation of both points is at least 1 cm.
Coordinates invalid! No coordinates or invalid coordinates for a point. Ensure that points used
have at least Easting and Northing coordinates.
Recording to interface! Data Output is set to Interface in the GENERAL SETTINGS menu. To be
