e.
On mounted post models, the height of the viewing head can be adjusted up or down on
the post in order to focus on different sized objects. Loosen the locking knob located on
the locking support collar, allowing the support collar to slide down to bottom of post.
While firmly holding focusing holder containing viewing head with one hand, loosen locking
knob located on back of focusing holder so that head can move freely up or down on post.
While looking through microscope, move viewing head up or down on post until object
can be seen in approximate focus. Tighten focusing holder locking knob. Position the
support collar under the focusing block and tighten locking knob on support collar. It is not
necessary to make this adjustment every time you change objects to be viewed, so long as
the different objects are of similar thickness or height.

to the traverse permitted by the regular focusing knobs.
