(3) Detaching the Fine Adjustment Knob
The fine adjustment knob is designed detachable in order to
prevent interference between the knob and the operator's
hand manipulating the X- and Y- axis knobs.
Loosen the clamping screw using the Allen screwdriver and
remove the fine adjustment knob.
After detaching, the seat of the fine adjustment knob is
hollowed to facilitate manipulation with the thick of a finger.
(4) Pre-focusing Lever
The pre-focusing lever prevents collision between the
specimen and objective and simplifies the focusing operation.
After bring the specimen into approximate focus with the coarse adjustment knob, turn the
pre-focusing lever in the direction of the arrow to lock it. Hereafter, the upper limit of the coarse
adjustment will be limited at the position where the lever is locked.
When bringing a specimen in focus, approximate focus can be obtained by simply raising the
coarse adjustment to the stop position so all you have to do more is control the fine adjustment
knob. The stage up/down movement using the fine adjustment knob is not limited.
When the pre-focusing lever is locked, the coarse adjustment stroke is limited by the
mechanism and it cannot reach the previous lower limit. If you want to control the coarse
adjustment knob to the previous lower limit, unlock the pre-focusing lever.
