8. Checking the accuracy
Check the accuracy of the Hultafors H3x360G
before each measurement.
• Before starting the check, let the device
acclimatise to the environmental conditions.
8.1 Checking the accuracy of the
vertical line
• Attach a plumb line as close as possible
possible to a (at least) 3 m high wall.
• Mount the H3x360G onto a tripod at a height
of approx. 1.2 m.
• Position the device approx. 3 m in front of the
plumb line.
• Switch on the H3x360G and project the
vertical laser line onto the plumb line.
If the deviation is greater than 4 mm, the device
must be readjusted. In this case, consult your
dealer.
8.2 Checking the leveling accuracy of
the horizontal line
1. Select two horizontal, flat walls (A & B), which
are approx. 10 meters apart.
• Mount the H3x360G onto a tripod and position
it at a distance of approx. 20 cm from wall A.
• Mark the intersecting point
of the vertical
and horizontal lines on wall A.
2. Rotate the H3x360G by 180° and mark point
on wall B.
• Position the laser at the same height approx.
20 cm away from wall B and mark point
on
wall B.
3. Rotate the H3x360G by 180° and mark
point
on wall A.
• Measure the vertical distance
of the
marked points
-
and the vertical spacing
of the points
