– Turn the measuring tool 180° without adjusting the height.
Allow it to level in, then mark the centre point of the laser
beam on wall A (point III). Ensure that point III is as vertical
as possible above or below point I.
– The discrepancy d between the two marked points I and III
on wall A reveals the actual height deviation of the measuring
tool along the longitudinal axis.
The maximum permitted deviation on the measuring distance of
2 × 5 m = 10 m is as follows:
32 ft x ±0.0036 in/ft = ±1/8 (0.115 in)
(10 m × ±0.3 mm/m = ±3 mm)
The discrepancy d between points I and III must therefore
amount to no more than 3 mm.
GPL100-50G: Repeat the measuring process for the two side
laser beams that run along the transverse axis of the measuring
tool. To do this, turn the measuring tool 90° clockwise or anti-
clockwise before beginning the measuring process.
