8.2.3 Pre-focusing Lever
●
The pre-focusing lever

ensures that the objectives does not come in contact with the specimen
and simplifies focusing.
●
After focusing on the specimen with the coarse adjustment knob, turn this lever clockwise and lock.
The upper limit on coarse adjustment movement is set at the locked position.
●
After changing a specimen, refocusing is easily accomplished by rotating the coarse adjustment
knob to reach the pre-focused position, then making fine adjustment with the fine adjustment knob.
●
Turn the lever counterclockwise to unlock.
NOTE
When the pre-focusing lever is locked, a coarse movement stroke is reduced due to the
microscope’s
mechanism, causing the stage not to be able to be lowered to the lower limit. To lower the stage to the
lower limit, release the pre-focusing lever.
