Stake out function
Two different distances (a and b) can be entered into
the instrument and can then be used to mark off
defined measured lengths, e.g. in the construction of
wooden frames.
See figure {L}.
Entering stake out distances:
Press this button four times and the stake out
function symbol appears in the display .
The value (a) and the corresponding intermediate line
flash.
By using and , you can adjust the values
(first a and then b) to suit the desired stake out
distances. Holding the buttons down increases the
rate of change of the values.
Once the desired value (a) has been reached it can be
confirmed with the button.

defined value (a) is automatically adopted). Value (b)
can be entered using and .
The defined value (b) is confirmed with the
button.
Pressing the button starts the laser measure-
ment. The display shows required stake out distance
in the summary line between the stake out point
(first a and then b) and the instrument (rear refer-
ence).
If the Racer is then moved slowly along the stake out
line the displayed distance decreases. The instrument
starts to beep at a distance of 0.1m from the next
stake out point.
The arrows in the display indicate in which direc-
tion the Racer needs to be moved in order to achieve
the defined distance (either a or b). As soon as the
stake out point is reached the beep changes and the
intermediate line starts to flash.
The function can be stopped at any time by pressing
the button.
Indirect measurement
The instrument can calculate distances using
Pythagoras’ theorem.
)Make sure you adhere to the prescribed
sequence of measurement:
• All target points must be in a horizontal or vertical
plane.
• The best results are achieved when the instru-
ment is rotated about a fixed point (e.g. with the
positioning bracket fully folded out and the
instrument placed on a wall).
