Specify the search measurement conditions and the judgement conditions for the measurement results.
  1. In the Item Tab area, tap [Measurement].
  2. In the "Measurement condition" area, specify a value for each item.

    Setting item
    Set value
    [factory default]
    Description
    Sub-pixel
    • Checked
    • [Unchecked]
    When a check is placed at sub-pixel, the position information can be measured in units of sub-pixels.However, this requires more processing time.
    Candidate level
    0 to 100
    [70]
    Specify the threshold value with which to detect candidate points in a rough search.Specify a smaller value when model search results are unreliable.
  3. When the setting has been changed, tap [Measurement] in the Detail area to verify whether measurements can be made correctly.

    Position Y
    -99999.9999 to 99999.9999
    Specify the range of Y-axis shifting that is judged to be OK.
