Leica LS10 - Measurement Procedure for Linelevel

Field Description
Method Select a levelling method:
•
BF: Backsight and foresight are measured according to
the pattern BF BF.
•
BFFB: Backsight and foresight are measured according
to the pattern BFFB BFFB.
•
BBFF: Backsight and foresight are measured according
to the pattern BBFF BBFF.
•
BFBF: Backsight and foresight are measured according
to the pattern BFBF BFBF.
•
aBF: Backsight and foresight are measured alternatingly
according to the pattern BF FB BF FB.
•
aBFFB: Backsight and foresight are measured alternat-
ingly according to the pattern BFFB FBBF BFFB.
•
aFBBF: Backsight and foresight are measured alternat-
ingly according to the pattern FBBF BFFB FBBF.
•
sim aBFFB: This levelling method allows to simultan-
eously measure two lines that have the same start and
end point. In the forward direction of the line observa-
tions in both lines start with BFFB and continue with
FBBF, BFFB and so forth. The backwards direction of the
line is started with FBBF, followed by BFFB, FBBF and so
forth.
•
SimBF: This levelling method allows to simultaneously
measure two lines that have the same start and end
point. Backsight and foresight are measured according
to the pattern BF(Line1) BF(Line2) BF(Line1) BF(Line2).
•
SimBFFB: This levelling method allows to simultaneously
measure two lines that have the same start and end
point. Backsight and foresight are measured according
to the pattern BFFB(Line1) BFFB(Line2) BFFB(Line1)
BFFB(Line2).
PtID ID of the starting point.

7.4.5 Measurement Procedure for LineLevel
If a new line is started, the rst measurement screen is either the backsight or
the foresight measurement, depending on the selected levelling method. On
each screen, the current measurement (Backsight/Foresight) is indicated by
the viewing direction which is highlighted in red. In the following example, the
levelling method BFFB is used to describe the measurement procedure of the
LineLevel application. For other levelling methods, the sequence of screens
may differ.
