Marking inclined lines (see fig. 12.2)
Also the button 5 disables the sound signal and
the blinking of laser beams (which signal that tilt
of appliance more than ±3°), this allows you to
mark inclined lines�
•
Set lock 9 to position as shown in fig. 12.2.
•
To turn on this working mode, press and re-
lease the button 5� Indicator 7 lighting on, indica-
tor 4 will start blinking�
To turn off this working mode, press and re-
•
lease the button 5� Indicators 7 and 4 goes out�
Universal holder (see fig. 3-8)
The universal holder 18 allows you to install the
appliance on various objects, and to change the
position of the appliance easily, quickly and ac-
curately (move, turn)�
Working advice
Precision test
The appliance is ready for opera-
tion. The accuracy of the appliance
has been verified at the factory.
If measurement error exceeds maxi-
mum allowable variance during
the precision test, please contact
CROWN service centre.
Factors, influencing appliance precision:
•
ambient temperature, e�g�, temperature
difference which may take place with distance
from the ground� Temperature difference is
most considerable near ground surface, there-
fore it is recommended to use the tripod for
measurements in areas with length exceed-
ing 20 m;
•
contamination of the laser emitter window�
Always check protective windows for contami-
nations before use and clean them if neces-
sary;
•
measurement through transparent surfac-
es (windows, aquariums, etc�)� It is not recom-
mended to carry out such measurement;
measurements on reflective surfaces (mir-
•
rors, polished metal surfaces, etc�)� It is not
recommended to carry out such measure-
ment�
•
presence of steam, dust, smoke, etc� in the
air� It is not recommended to carry out such
measurement;
•
fall of the appliance or a heavy shock� In
this case it is recommended to perform a pre-
cision test� If maximum allowable variance is
exceeded, please contact CROWN service
centre�
General recommendation (see fig. 12)
•
Before starting work ensure that all measure-
ments will be carried out under suitable condi-
tions (see section "Factors, influencing appliance
precision")�
Place the appliance correctly as described
•
above and turn on it� If you hear a sound sig-
nal when turning on the appliance and the laser
beams blink, you have to re-position the appli-
ance, otherwise the measurement results will be
incorrect� Negligible horizontal misalignment can
be compensated with the laser head self-levelling
system (not exceeding ±3°)�
•
After finishing work turn off the appliance as
described above (lock 9 shall be in the position as
shown in fig. 12.2 and laser beams must be off).
•
It is recommended to put the appliance for
long-term storage and transportation into bag 22
(CT44059, CT44061, CT44062) or into case 17
(CT44060, CT44065)� Ensure that there are no
moisture drops on the appliance elements (if
necessary, wipe with a soft cloth), after that put
the appliance into bag 22 (CT44059, CT44061,
CT44062) or into case 17 (CT44060, CT44065)�
Marking inclined lines (see fig. 12.2, 14)
In order to tilt the appliance, it's
recommended to mount it on a tri-
pod 29 that can tilt (tripod 29 is not
included in delivery set).
Attention! Do not mark horizontal
and vertical lines in this mode -
the position of the respective laser
beams may be incorrect (because
signal about impossibility of laser head self-
leveling is missing).
•
Mount appliance on tripod 29 (not included in
delivery set)�
•
Set lock 9 to position as shown in fig. 12.2.
•
Press and release the button 5� Indicator 7
lighting on, indicator 4 will start blinking (see
fig. 14.1).
•
Gently tilt the appliance to the desired angle
(see fig. 14.2).
