Functions
CenterFind mode (see figure C)
In CenterFind mode, the rotary laser auto-
matically attempts to align the laser beam to
the center line of the laser receiver by moving
the rotation head up and down.
If the rotary laser is in the horizontal position,
the laser beam can be aligned in relation to
the X-axis of the rotary laser, to the Y-axis or to
both axes at the same time (see “Inclination
Determination with CenterFind mode (see
figure D)”, page 4). If the rotary laser is in the
vertical position, only alignment to the Y-axis
is possible.
Start CenterFind mode:
Position the rotary laser and laser receiver so
that the laser receiver is situated in the direc-
tion of the X-axis or the Y-axis of the rotary
laser. Align the laser receiver so that the re-
quired axis is at a right angle to the reception
area (1). If the laser beam is aligned to both
axes, then place a laser receiver connected to
the rotary laser in the direction of the X- and Y-
axis respectively. Each laser receiver must be
situated within the pivoting range of ±8.5% of
the rotary laser.
Switch on the rotary laser in rotary operation.
In the settings menu, the center function
must be put in CenterFind (CF) mode. When
aligning to two axes of the rotary laser, this
applies to both laser receivers.
To start CenterFind mode for the X-axis, ei-
ther press and hold the CenterFind (17) mode
button, or press and hold the CenterFind (17)
mode button together with the X-axis button
(16). To start CenterFind mode for the Y-axis,
press and hold the CenterFind (17) mode
button, together with the Y-axis button (15).
Should the laser beam be aligned to both axes
at the same time, CenterFind mode must be
started separately on each laser receiver.
Following the start of CenterFind mode, the
rotary head on the rotary laser moves up and
down. During the search process, CFX (X-axis)
or CFY (Y-axis) appears in the text display (e).
If the laser beam hits the reception area (1)
at the height of the center line of the laser re-
-13-
ceiver, the center line indicator (h) will appear
and XOK (X-axis) or YOK (Y-axis) will appear
on the display (e). The value of the incline that
is found is displayed on the rotary laser. Cen-
terFind mode then ends automatically.
Cancelling CenterFind mode:
To cancel the CenterFind mode, press and
hold the CenterFind mode button (17).
Troubleshooting:
If the laser beam was unable to find the cen-
ter line of the laser receiver within the pivot-
ing range, ERR appears in the text display (e)
and all LED direction indicators light up.
Press any button on the rotary laser or laser
receiver to close the error message. Reposi-
tion the rotary laser and laser receiver so that
the laser receiver is situated within the pivot-
ing range of ±8.5% of the rotary laser. Ensure
that the laser receiver is aligned to the X-ax-
is or Y-axis so that the laser beam can pass
through the reception area (1) horizontally.
Then restart the CenterFind mode.
If both axes of the rotary laser should be
aligned to a laser receiver, the same center
function must be set on both laser receivers.
A combination of CenterFind mode and Cen-
terLock mode is not possible. If CenterLock
mode is already set on one axis and Center-
Find mode is started on the other axis, ERR
and CL will appear alternately in the text dis-
play (e). Select CenterFind mode on both la-
ser receivers and re-start the function.
Inclination determination with CenterFind
mode(seegureD)
Using CenterFind mode, the inclination of a
surface can be measured up to max. 8.5%. To
do this, set up the rotary laser at one end of
the inclined surface in a horizontal position
on a tripod. The X- or Y-axis of the rotary la-
ser must be aligned with the inclination to be
determined. Switch on the rotary laser and al-
low it to level in.
Secure the laser receiver to a measuring rod
(25) with the bracket. Place the measuring
rod near to the laser level (at the same end of
the inclined surface). Align the height of the
laser receiver on the measuring rod so that
the laser beam of the rotary laser is indicated
as “centered”
1 2
.
Then place the measuring rod with the laser
receiver at the other end of the inclined sur-
face at
1 2
. Ensure that position of the laser
receiver on the measuring rod remains un-
changed.
Start CenterFind mode for the axis to which
the inclined surface is aligned. At the end of
CenterFind mode, the inclination of the sur-
face is shown on the rotary laser.
In CenterLock mode, the rotary laser auto-
matically attempts to align the laser beam to
the center line of the laser receiver by moving
the rotation head up and down. In contrast
to the CenterFind mode, the position of the
laser receiver is continually checked and the
inclination of the rotary laser automatically
adjusted. No slope values appear on the dis-
play of the rotary laser.
Alignment is possible for the X-axis and Y-axis
both when the rotary laser is in a horizontal
position and when it is in a vertical position.
Start CenterLock mode:
Position the rotary laser and laser receiver so
that the laser receiver is situated in the direc-
tion of the X-axis or the Y-axis of the rotary
laser. Align the laser receiver so that the re-
quired axis is at a right angle to the reception
area (1).
If the laser beam is aligned to both axes, then
place a laser receiver connected to the rotary
laser in the direction of the X- and Y-axis re-
spectively. Each laser receiver must be situ-
ated within the pivoting range of ±8.5 % of the
rotary laser.
Switch on the rotary laser in rotational opera-
tion.
In the settings menu of the laser receiver, the
center function must be put in CenterLock
(CL) mode. When aligning to two axes of the
rotary laser, this applies to both laser receiv-
ers.
To start the CenterLock mode for the X-axis,
either press and hold the CenterFind (17)
mode button, or press and hold the Center-
Find (17) mode button, together with the
X-axis button (16).
To start the CenterLock mode for the Y-axis,
press and hold the CenterFind (17) mode
button, together with the Y-axis button (15).
Should the laser beam be aligned to both axes
at the same time, CenterLock mode must be
started separately on each laser receiver.
Following the start of CenterLock mode, the
rotary head on the rotary laser moves up and
down. During the search process, CLX (X-ax-
is) or CLY (Y-axis) appears in the text display
(e).
-14-
If the laser beam hits the reception area (1)
at the height of the center line of the laser
receiver, the center line indicator (h) and LOC
is displayed on the text indicator. The Center-
Lock symbol is displayed on the rotary laser
on the start screen for the corresponding axis.
In the event of changes to the position of the
laser receiver or rotary laser, the inclination
is automatically adjusted on the rotary laser.
u Take great care when working with the
CenterLock mode that rotary lasers and
laser receivers are not moved uninten-
tionally. Incorrect measurements can arise
from the automatic adjustment of the incli-
nation with every change of position.
Cancelling CenterLock mode:
To cancel or end the CenterLock mode, press
and hold the CenterFind mode button (17).
If the laser beam was already successfully
aligned with the center line of the laser receiv-
er at this point, the set inclination remains on
the rotary laser even when CenterLock mode
is cancelled.
Troubleshooting:
If the laser beam was unable to find the cen-
ter line of the laser receiver within 2 min (no
matter whether at the start of the mode or
after changes to position), ERR appears in the
text display (e) and all LED direction indica-
tors light up.
Press any button on the rotary laser and one
on the laser receiver to close the error mes-
sages. Reposition the rotary laser and laser
receiver so that the laser receiver is situated
within the pivoting range of ±8.5 % of the
rotary laser. Ensure that the laser receiver is
aligned to the X-axis or Y-axis so that the la-
ser beam can pass through the reception area
(1) horizontally. Then restart the CenterLock
mode.
If both axes of the rotary laser should be
aligned to a laser receiver, the same center
function must be set on both laser receivers.
A combination of CenterLock mode and Cen-
terFind mode is not possible. If CenterFind
mode is already set on one axis and Center-
Lock mode is started on the other axis, ERR
and CF will appear alternately in the text dis-
play (e). Select CenterLock mode on both la-
ser receivers and re-start the function.
Anti-strobe protection filter
The laser receiver has electronic filters for
strobe light. The filters protect against, for ex-
ample, interference from the warning lights of
construction machinery.
Practical Advice
Aligning with the spirit level
The laser receiver can be aligned vertically
(plumb line) with the spirit level (7). If a laser
receiver is mounted at an angle, it will give
incorrect measurements.
Marking
You can mark the position of the laser beam at
the center mark (9) on the left and right of the
laser receiver when the beam hits the center
of the reception area (1).
When marking, take care to align the laser
receiver so that it is exactly vertical (with a
horizontal laser beam) or horizontal (with a
vertical laser beam), as otherwise the marks
are offset with respect to the laser beam.
Attachingusingthebracket(seegureE)
You can use the bracket (23) to attach the la-
ser receiver to a measuring rod (25) (acces-
sory) as well as to other objects with a width
of up to 2.5 in.
Screw the bracket (23) to the mount (11) on
the rear side of the laser receiver with the fas-
tening screw (26).
Loosen the rotary knob (24) on the bracket,
slide the bracket onto the measuring rod (25)
and retighten the rotary knob (24).
You can use a spirit level (21) to ensure that
the bracket (23) is horizontally aligned along
with the laser receiver. If a laser receiver is
mounted at an angle, it will give incorrect
measurements.
The center line (22) of the bracket is located
at the same height as the center mark (9) and
can be used to mark the laser beam.
Attaching using a magnet (see figure F)
If an attachment is not required to be espe-
cially secure, the laser receiver can be at-
tached to steel parts using the magnets (10).
