Field calibration check (fi g. G1–G3)
The fi eld calibration check must be performed securely and accurately to
make a correct diagnosis. Whenever an error is registered, have the tool
serviced by a qualifi ed repair agent.
WARNING: The conditions of the area are indicative of the
results presented. If the practice differs from these conditions,
the measurements have to be adjusted accordingly.
• Place the tool in an area of at least 10 m by 5 m. Position the tool so
that it is aimed front-to-back towards the short walls.
• Place the tool at approximately 10 cm from the wall as measured from
the rear of the tool. Mark the intersection point of the laser lines (8).
• Switch on the tool. Mark the centre of the laser line (9) pointing forward
on the opposite short wall.
• Locate the position of the laser beam halfway between the short walls
using a target. Mark this point (10) on the fl oor. Switch off the tool.
• Move the tool in a straight line to the fl oor marking (10).
• Switch on the tool. Align the intersection point of the laser lines with the
fl oor marking (10).
• Align the laser beam pointing forward with the wall marking (9).
• Mark the centre of the laser line pointing sideways (11) on the long wall.
• Switch off the tool and rotate it 90° counterclockwise.
• Switch on the tool. Align the intersection point of the laser lines with the
fl oor marking (10).
• Align the laser beam pointing forward with the wall marking (11).
• Locate the position of the laser beam pointing sideways parallel to the
starting point (8) at the short wall using a target. Mark this point (12) on
the fl oor. Switch off the tool.
• Measure the difference between the markings (8 & 12).
• If the difference between the markings is 4 mm or less, the tool is
properly calibrated.
• If the difference between the markings is more than 4 mm, the tool must
be serviced.
