9-3 Drop Prevention Collar SZX-R and Auxiliary Pillar SZH-P400/SZH-P600

}The auxiliary pillar is to be used when observing a large specimen or when it is required to move the microscope body

height using a low-magnification objective.

}The drop prevention collar prevents the zoom microscope body from dropping when installed at a high position using the

auxiliary pillar and the clamping knob on the focusing assembly is loosened carelessly. This helps to prevent accidental

damage to the specimen or objective.

# The static load resistance of the SZX-R is 7 kg at maximum.

Assembly

Operation

When moving the microscope body around the pillar, never loosen both the focusing assembly clamping knob

and drop prevention collar simultaneously.

To move the microscope body upward

1. Loosen the clamping knob of the focusing assembly to be moved upward.

2. At the desired height, tighten the focusing assembly clamping knob securely.

3. Loosen the drop prevention collar clamping knob.

4. Press the drop prevention collar tightly against the lower end of the focusing assembly and tighten the clamping knob

securely.

To move the microscope body downward

First loosen the drop prevention collar, then move the microscope body downward.

# For the drop prevention collar to exhibit its full effect, clamp the focusing assembly and drop prevention collar in

close contact between each other, without leaving any space.

1. Mounting the auxiliary pillar

· Remove the pillar from the standard base and replace the pillar with the

SZH-P400 or SZH-P600 auxiliary Pillar (see page 3 for the mounting pro-

cedure).

2. Mounting the drop prevention collar

· Fit the drop prevention collar @ onto the auxiliary pillar ².

}Position the oblique illumination unit* mounting groove ³ on the front

side of the drop prevention collar @ and tighten the clamping knob |.

* The LSGA focal illumination unit and SZX-LGH1 light guide can be

mounted.

# When the specimen height is low or an objective with a short work-

ing distance is used, the drop prevention collar @ does not have to

be mounted if the working distance corresponding to the collar is

not available. However, this reduces safety that is assured by using

the SZX-R drop prevention collar @, so be always sure to hold the

focusing assembly when loosening the focusing assembly clamp-

ing knob.
