CONFIG 2/6 Screen Setup
}The CONFIG 2/6 screen is used to set the upper and lower limits of the
...
focusing mechanism.
The objective for use in the limit setting is the one with the highest mag-
nification or the one with the shortest WD (Working Distance) among the
ƒ
objectives used.
# Set the upper and lower limits of the focusing mechanism every
Š
time the thickness of a specimen changes. Otherwise, the objective
may collide with the specimen.
}The BF observation light path is selected automatically when the CONFIG
2/6 screen is displayed.
# During display of the CONFIG 2/6 screen, the upper and lower limits
of the focusing mechanism are not set. Be careful not to collide the
specimen with an objective.
1. Touch the objective No. switch @ for the objective with the lowest magni-
fication to engage it in the light path.
2. Place a specimen on the stage and adjust the focus.
²Coarse adjustment switches: Touch and hold either switch to drive
³Fine adjustment switches: Each touch of a switch displaces the
Hand switch (MX-HS61A): Rotate the jog dial to displace the stage
}The operations in steps 1 and 2 above are intended to facilitate focus
adjustment using the objective with the highest magnification.
3. Touch the objective No. switch @ for the objective for use in the upper
limit setup to engage it in the light path.
4. Focus on the specimen and press the SET switch | to set the upper
limit position.
# Unless you proceed to the next screen (CONFIG 3/6 screen), the set
limit will not be valid. So be careful.
The upper limit position is equal to:
MCurrent stage position + Minimum WD of the objectives used
5. To set the lower limit for transmitted light observation, touch the DIA switch ƒ.
}The lower limit position (15000.00 μm) will be fixed.
6. To set the lower limit for reflected light observation, touch the EPI switch ....
· Touch the SET UP switch to enter the lower limit setup mode. (The SET
UP switch will function as the OK switch at this time.)
· Move the stage to a lower position where you want to set it and press the
OK switch.
}The default lower limit position is 1000.00 μm.
