Setting the movement limit with the coarse focusing knob

This function prevents the collision between the sample and the
objective and also simplifies the focusing.
After the sample is brought into focus by the coarse focusing knob,
if you turn the pre-focusing lever a in the arrow direction to lock
it, the upper limit of the coarse focusing knob is set at the locked
position.
In case you focus again after replacing the sample, the sample can
be brought into focus approximately by raising the coarse focusing
knob to the stop position. Then, adjust finely using the fine focusing
knob.
Note, the stage movement is not locked by the fine focusing knob.
If the pre-focusing lever is locked, the stage is not lowered
NOTE
to the lower limit.
