Using Eyepiece Micrometer Disks
(Fig. 25)
Eyepiece micrometer disks can be inserted into WHN10X-H (or WHN10X)
eyepieces.
When the eyepiece in use does not have a diopter adjustment function,
the micrometer disk cannot be brought into focus if you have poor eye-
sight. Should that be the case, adjust the focus with eyeglasses on.
Use 24 mm diam. x 1.5 mm micrometer disks.
Following Fig. 25, turn the built-in micrometer mounting frame ² counter-
clockwise to remove it from the eyepiece and place a micrometer disk @
into the mounting frame. The engraving on the micrometer disk should
face downward into the micrometer mounting frame.
Screw the micrometer mounting frame back into the eyepiece sleeve.
