Working advice
Precision test
The appliance is ready for opera-
tion. The accuracy of the appliance
has been veried at the factory.
If measurement error exceeds maxi-
mum allowable variance during
the precision test, please contact
CROWN service centre.
Factors, inuencing 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 reective 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 g. 12)
•Before starting work ensure that all measure-
ments will be carried out under suitable condi-
tions (see section "Factors, inuencing 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 nishing work turn off the appliance as
described above (lock 9shall be in the position as
shown in g. 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 g. 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 g. 12.2.
•Press and release the button 5� Indicator 7
lighting on, indicator 4will start blinking (see
g. 14.1).
•Gently tilt the appliance to the desired angle
(see g. 14.2).
