Magnification Indicator Ring

}Every objective other than the 1X objective is provided with an observa-

tion magnification* indicator ring.

* This refers to the total magnification when the 10X eyepiece is used.

}When the revolving nosepiece (SZX-2RE) is used, the total observation

magnifications when two objectives are switched can be read directly by

mounting these rings on the left and right zooming knobs.

1. Hold the magnification indicator ring @ in an orientation allowing correct

magnification reading from the front of the microscope, widen the ring

and mount onto the base of the left zooming knob ².

2. Rotate the magnification indicator ring gently until it stops at the speci-

fied position.

# A magnification indicator ring can also be mounted on the right

zooming knob in the same way as above, but this makes the total

observation magnification when the 1X objective is used unread-

able.

Using the Auxiliary Objective

(SZX-AL20X)

}This is a 2.5X auxiliary objective for exclusive use with the DFPLAPO1XPF

objective. It is effective for non-covered specimen observation when the

cap is attached to the tip and for observation through a 2 mm-thick water

or glass layer when the cap is removed. (Fig. 17)

# The recommended zoom magnifications for exhibiting high per-form-

WD 7mm

ance are the higher magnifications from 4X to 9X (i.e. total magnifi-

cations* of 100X to 225X). It is not advisable to use magnifications

lower than 4X. If the zoom magnification is lower than 2X, part of the

image will be obscured.

* Zoom magnification (4X to 9X) X Auxiliary objective (2.5X) X Eyepiece

(10X)

Removing the Cap

Hold the rotary ring @ and rotate the fixing ring ² in the direction of the

arrow to remove the cap. (Fig. 18)

Parfocal Correction Ring

}This is convenient when using a parfocal objective (PF) with the SZX-2RE

revolving nosepiece ³ and the SZX-AL20X. (Fig. 19)

· Attach the provided parfocal correction ring | to the DFPLAPO1XPF ƒ
