Alignment
Measure each misalignment value and calculate the ratio of this value by using the maximum indicated value.
The sum of these ratios must be less than 1:

dr/△ r + dr/△ α < 1
  • dr = measured radial misalignment value
  • △ r = max.radial misalignment value
  • d α = measured angular misalignment value
  • △ α = max. angular misalignment value

Correct alignment if this sum is greater than 1.
