Mitutoyo SJ-210 - Traversal Length

No. 99MBB122A
18-16
18.4 Traversal Length
In the SJ-210, 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 vary depending on the filter used.
When the pre-travel and post-travel settings are 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 7.9, “Setting
Pre-travel/Post-travel”.
Measuring operation
Measurement starts from the origin position. When measurement has been completed,
the detector returns to the origin.
■ Traversal length
 When the 2CR filter is selected
Traversal length (When 2CR filter is selected)
 When GAUSS filter is selected
Traversal length (When GAUSS filter is selected)
Data from the pre-travel length and the post-travel length are calculated assuming that
their lengths are ℓ/2.
