SZ2 series
WHSZ10X-H/15X-H/20X-H
Rotate the disk-mounting ring a of the eyepiece counterclockwise
to remove.
Prepare an eyepiece micrometer disk b (24 mm dia. x 1.5 mm thick),
remove dust and dirt from its surface, and fit it into the disk-mounting
ring a so that the engraving on the micrometer disk faces downward.
Gently screw in the disk-mounting ring a incorporating the eyepiece
micrometer disk into the eyepiece. Turn the ring clockwise to attach
it firmly.
WHSZ30X-H
Rotate the disk-mounting ring c of the eyepiece counterclockwise
to remove.
Rotate the push ring d of the eyepiece micrometer disk
counterclockwise to remove.
Prepare an eyepiece micrometer disk e (24 mm dia. x 1.5 mm thick),
remove dust and dirt from its surface, place it on the disk-mounting ring
c with the engraving facing downward, and fix it with the push ring d .
Gently screw in the disk-mounting ring c incorporating the eyepiece
micrometer disk into the eyepiece. Turn the ring clockwise to attach
it firmly.
· The micrometer disk frame may be tight for certain micrometer disks.
In this case, turn the frame by holding the circumference with
a light, uniform force or by applying the frame against a rubber
sheet. Do not grasp the frame with a strong force, as this may
deform the frame and make it harder to remove it.
· Be careful not to touch the lens surface with your finger.
Due to their structures the WHSZ20X-H/30X-H eyepieces
apply a magnification on the focused plane of the
eyepiece micrometer disk.
These magnifications are 1.3X with the WHSZ20X-H and
2X with the WHSZ30X-H. Be sure to compensate for these
magnifications when using the eyepiece micrometer disk
in measurements.
Also, insertion of the eyepiece micrometer disk extends
the light path length and deviates the position of the
diopter scale. Correct this deviation by turning the diopter
adjustment ring of the eyepiece toward “+”.
When the eyepiece micrometer disk is not used, store it by
wrapping in a clean, soft cloth.
