When the whole vibration width is "approx. 75 mm", the center vibration width is 75 - (17.5 + 17.5)
= 40 mm. The standard value after the gyro-gain adjustment is 40×1/8 = 5 mm (center vibration
width), so the whole vibration width is 5 + (17.5+17.5) = 40 mm.

Measure the vibration width by changing the adjustment value in increments of 0.02-Step as below.
③
The peak zone of the minimum vibration width can be obtained by the actual measured value.
The middle of the peak zone is regarded as the adjustment value.

:
Measure the vibration width in increments of 0.5 mm.
①
For adjusting the center vibration width of the laser beam, calculate as follows:
Measure the whole vibration width ( α) as in Procedure "12." (Page A65). Then, subtract the top and
bottom radial parts (shaded areas) of the laser spots from it and work out the center vibration width (α′).
