Specimen exchange positions: X: 25.0 mm
Y: 25.0 mm
R: 0゜
T: 0゜
Z: 8.0mm
CAUTION
Specimen height must be adjusted carefully. It must not be 0.5mm higher than the bottom of
the height gauge. If it is higher than this, the specimen may strike the objective lens and
cause damage when operating at a short working distance or at a high tilt angle. Also,
accurate setting of specimen height minimizes image shift during specimen tilting.
