8. Checking the accuracy
Check the accuracy of the Hultafors H360G
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 H360G 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 H360G 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 H360G 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.
