CHECKING THE CALIBRATION
28
Controlled Test
●
Position the FRE-203XT laser on it’s tripod in the
middle
of your offi ce, garage, workshop
etc... somewhere where you have space (10m or similar).
●
Ensure there is no glazing or refl ective surfaces in line of sight of the laser beam. This is
to prevent the Refraction of the laser beam (See Refraction Issues section on page
29
for
further details).
●
Turn off all the lights and press the
ON/OFF
button once and the FRE-203XT will power on
and begin automatically self-levelling horizontally.
●
No other button needs to be pressed for the laser to self level.
●
This self levelling process takes around 15-20 seconds and then the prism will start spinning
and will project a red beam 360 degrees around the room.
●
With the laser level keypad facing your chest (towards you) walk to the left hand wall and
mark the position of the laser beam on the wall.
●
With the laser level keypad facing your chest (towards you) walk to the right hand wall and
mark the position of the laser beam on the wall.
●
Walk back to the laser and carefully twist the laser level round so the laser keypad now faces
the left wall.
●
Be extremely careful not to overly disturb the laser when twisting it round to the point the
tripod position moves or is kicked.
●
The laser will momentarily stop and re-start when turned round. This is normal. The laser will
then self level again and project a red beam 360 degrees around the room.
●
Walk to the datum marks on both the left and right wall. You should see that the beam is
hitting these marks.
●
If it is hitting the datum marks then the laser is operating correctly.
If you believe the FRE-203XT is not giving accurate datums (after ensuring you have completely
ruled out refraction of the laser beam explained on page
29
), please carry out the following
controlled test in your offi ce, or another indoor location.
If it’s not hitting the datum mark’s...
(and you have 100% ruled out Refraction and have not enabled Manual override)
Please contact the Service Department:
08000 869 769
who will be able to advise
how to send it for repair / calibration.
