Compensating crosshair magnification offsets
Many systems that include multiple lenses are mechanically calibrated so that
no position offsets occur when changing magnifications. However, any posi-
tion offsets that do occur can be eliminated using the Probe Properties offset
compensation function. The process of eliminating probe offsets for multiple
crosshair magnifications is diagrammed here and described below.
To compensate crosshair probe offsets:
1 Select a magnification as the position
reference for all other magnifications. In
this example, the X10 probe magnification
is selected as the reference.
2 Click the Probe/Crosshair Properties
menu item to display the X and Y offsets for
the reference magnification (X10) probe.
3 Use the reference probe magnification to measure a circle. Collect a
minimum of 4 points.
This circle will serve as a reference feature for subsequent measurements us-
ing other probe magnifications.
