Corresponds To 1 Click On The Adjustment Device
Information
A calculated value in the positive range means: Turn adjustment device towards A - loosen.
A calculated value in the negative range means: Turn adjustment device towards B - tighten.
Adjustment dimension = required dimension - actual dimension (required dimension minus actual dimension)
Example:
Actual dimension: 2.6 mm
Required dimension: 2.0 mm (+/- 0.3 mm)
Adjustment dimension = required dimension - actual dimension
Adjustment dimension = 2.0 mm - 2.6 mm
Adjustment dimension = -0.6 mm
-0.6 mm: 0.15 mm = - 4 clicks (0.15 mm corresponds to one click!)
Adjustment dimension = -0.6 mm: This means that the gap dimension is too big and the adjustment device must be adjusted towards B - tighten.
