Specimen retraction
To prevent damage to the blade and specimen, the specimen is moved
away from the blade during the return motion to the upper home position.
The retraction value can be selected in 5 µm increments between 5 and
100 µm. Specimen retraction is set to 10 µm at the factory.
Specimen retraction can be disabled if required.
The selected setting is maintained when the instrument is turned off.
