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

objectives used.

# Set the upper and lower limits of the focusing mechanism every

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.
