23.4 Traverse Length
In the SJ-410, the traversal length is the sum of the measured length, the approach travel
length, the pre-travel length, and the post-travel length.
NOTE
• The pre-travel length and the post-travel length will vary depending on the filter used.
If the pre-travel and post-travel setting is set to NO, the traversal length is reduced by
the pre-travel length and the post-travel length.
For details about enabling/disabling the pre-travel and post-travel, refer to "7.3.7 Setting
pre-travel/post-travel" (page 7-30).

Data from the pre-travel length and the post-travel length are calculated assuming that
their lengths are ℓ/2.
