Reference Setting (Scan Edge Position)
When the measurement region is set, this position is automatically set at the same time as the reference
position. This item can be used to change the reference position to any desired position.
A reference position can be set either directly or by referencing a unit.
Specifying directly
Click a position on the image you want to use as a reference position, or set coordinate data for that point.
1 In the Item Tab area, click [Ref. setting].
In the display area, the current reference
position will be displayed as the crosshair
cursor.
2 In the "Method" area, select "Numerical".
3 Click the position to be set as the
reference.
4 Make fine adjustments using numeric
value inputs or the arrow buttons as
required.
5 To remeasure on the displayed image
and set the reference, click the [Measure
ref.] button.
6 To use data before position
compensation for the reference setting
coordinates, place a check at "Use point
coordinate before scroll".
Reference position usage method: Measuring the distance from a
specific position
• Positional deviation can be inspected by calculating the difference
be
tw
een the reference position and the measured position with an
expression.
After changing the reference position to any desired position, changing
the measur
ement region will automatically change it back to the default
position.
• Displaying the image enlarged makes this clicking easier.
