Calibrating offset
Pixel offsets of all lower magnifications must be calibrated against the highest magnification to ensure that
specimens remain in the center of the view when switching between magnifications. These calibrations
are performed as part of the overall initial setup of the video probe system, and should be performed under
the following circumstances:
• The first offset calibration is performed at the highest magnification to establish the calibration
magnification standard and time/date stamp the calibration.
• Offset calibrations at lower magnifications are performed after performing all pixel resolution
calibrations.
• Offset calibrations at lower magnifications are performed without adjusting the focus obtained
at the highest magnification.
To calibrate offset:
1 Click the Probe/Probe Library menu item to display the probe library, and then click the Offset tab.
