Beamage-M² User Manual Revision 6 28
If the quadratic fit curve passes under zero, the PC-Beamage software will try to solve the problem by
deleting the measurements farthest from ��0 and by automatically recalculating the value of M². The PC-
Beamage software will also offer a recommended travel distance between −3.5���� and 3.5���� to correct the
problem (see Figure 5-25).

A minimum of 5 beams must be detected to calculate M 2 .
Upon clicking the START ISO SCAN button, click Yes if you want to save previous data or No to ignore
them. The data erase themselves and then a new M² measurement begins automatically.
