2 Adjusting the X/Y-Axis Knob Tension
(Fig. 17)
}This mechanism is provided only with the U-SVRM/SVLM stage.
1. Hold the X-axis knob @ and slide up the Y-axis knob ² up to expose the
adjustment knobs.
2. Turning the X-axis adjustment knob ³ or Y-axis adjustment knob | clock-
wise (in the direction of the arrow) increases the tension and counter-
clockwise decreases it.
# If the tension is adjusted too tight, a creaking sound may be heard
during stage travel, and the stage stopping accuracy may be imper-
iled.
CAUTION
After long hours of use, the stage guide may be devi-
ated and the stage travel range may be decreased.
However, this is not malfunction and can be corrected
easily as described below.
[Treatment] X-axis direction: Hold the specimen holder and move the stage
guide to the left and right so that it hits the
stoppers.
Y-axis direction: Hold the upper stage and move it to the front
and rear so that it hits the stoppers.
Rubber Stage Knob Caps (Optional)
}When the stage feed knobs of the U-SVRM/SVLM are fitted with the rub-
ber knob caps, the knobs can be adjusted without slipping and fine
adjustment is possible by holding the knobs with a very light force. The
rubber knob caps also reduces fatigue after long hours of operation.
The U-SHGT thick type (thickness 5 mm) and U-SHG thin type (thickness
2 mm) rubber knob caps are available.
To attach the knob rubber caps:
First fit the larger rubber knob cap to the Y-axis (upper) knob from below
it, then fit the smaller rubber knob cap to the X-axis (lower) knob from
below it.
3 Using the Y-Axis Lock Lever
(Fig. 18)
}This mechanism is provided only with the U-SIC4R2/SIC4L2 stage.
1. When the Y-axis lock lever @ is locked by setting the lever in the direction
of the arrow, the Y-axis movement is locked, making it possible to scan
only in the X-axis direction.
2. To release the lock, return the lever to the original position.
# If the lock lever is released incompletely, the lever will be worn out,
making locking impossible or causing dust.
