Working Advice

Sighting Out a Reference Mark
While working, periodically check the initial set-up
height to ensure that it has not changed.
At the beginning of your work, make a reference mark
at a suitable distance (furthest possible) on a stable
surface (e.g. on a tree or building), which you can use
as your reference point.
Adjusting the Correct Height when Setting Up
the Measuring Tool (see figures C1 – C2)
Note: All height data are given with reference to the
canal ground (lowest point in the canal pipe).
– Fasten the measuring tool to a height-adjustable
stand (trivet plate mount) or position it in the man-
hole cone or riser with the appropriate legs.
– Use the three adjusting legs to set up the trivet
plate mount as level as possible (this is not neces-
sary when using self-levelling legs or when the
measuring tool is set up with the correct leg
length).
– Take care that the measuring tool is positioned
such that the laser beam is in the centre of the
manhole cone or riser.
– Use a levelling instrument or a rotational laser level
to set up the measuring tool at the correct height
(necessary depth X).
– Add the height Y of the levelling instrument/rota-
tional laser level above the reference point B to the
depth X.
The total height A now is the distance from the level-
ling instrument/rotational laser level to the bottom of
the canal pipe.
Meaning
Position of the remote control
behind the measuring tool
= Indication of the lateral alignment
above the grade readout.
Arrow symbol points toward the
measuring tool: Laser beam points
away from the remote control.
Position of remote control in front of
the measuring tool = Indication of
the lateral alignment below the
grade readout.
Arrow symbol points away from the
measuring tool: Laser beam points
towards the remote control.
