Focusing, Adjusting the Resistance of the Focus Drive
Focusing Focusing raises or lowers Emspira 3 using the
focusing drive. The specimen detail is brought
into sharp focus as soon as it is in the focal point
of the objective.
The focusing drive can be operated
either left- or right-handed.
Adjusting the resistance
Is the focusing drive too loose or too tight? Does
the equipment tend to slide downwards? The
resistance can be adjusted individually depen-
ding on the equipment weight and personal
preferences as follows:
1. Grip the drive knobs with both hands and
turn them towards each other until the
desired resistance is reached during focu-
sing.
On focusing columns with separate
coarse and fine adjustment, the
outer drive knobs have to be twisted
in opposite directions relative to
each other.
