・How to obtain the minimum value of the vibration width
① Measure the vibration width while changing the adjustment value that is set every 0.02Step as shown below.
② The peak section of the minimum vibration width can be obtained by the actual measured value.
③ Take the center of the peak section as the adjustment value.
Notes：When measuring the vibration width, read it in unit of 0.5mm.
① To adjust the vibration width at the center of the
laser spot beam, measure the whole vibration width
② Subtract the radius of the laser spot (oblique lined
vibration width.
Example）
13mm
8mm
When the whole vibration width is [About 40mm],
the center vibration width becomes be
45 - (2.5 + 2.5) = 40mm.
Standard after the gyro gain adjustment
40 × 1/5 = 8mm (Center vibration width)
Whole vibration width becomes be
8+ (2.5+2.5) = 13mm.
