・The laser spot beam is irradiated about 10mm in diameter at 5 m ahead.
50mm
40mm
・How to obtain the minimum value of the vibration width
①Measure the vibration width while changing the adjustment value that is set every 0.02Step as shown below.
②The peak section of the minimum vibration width can be obtained by the actual measured value.
③Take the center of the peak section as the adjustment value.
Notes:When measuring the vibration width, read it in unit of 0.5mm.
10mm
14.5mm
4.5mm

①To adjust the vibration width at the center of the
laser spot beam, measure the whole vibration width
first.
②Subtract the radius of the laser spot (oblique lined
part) from the top and bottom of the measured
vibration width.
Example)
When the whole vibration width is [About 42.5mm],
the center vibration width becomes be
50 - (5 + 5) = 40mm.
Standard after the gyro gain adjustment
40 x 1/5 = 8mm (Center vibration width)
Whole vibration width becomes be
4.5+ (5+5) = 14.5mm.
