• The micrometer reticle contains 5 different
micrometers respectively for the Sx, lOx, 20x, 50x
and l00x objectives. Turn the micrometer
changeover dial of the slider to switch to the
micrometer which suits the magnification of the
objective in the optical path.
• Insert the micrometer reticle into the scale port.
Adjust its position in the direction in which it slides
until the micrometer patterns are located to the right
hand side of the viewfield.
• The magnification of the objective corresponding to
the micrometer is indicated on the left side of each
micrometer pattern. Turn the micrometer
changeover dial to switch to the micrometer which
suits the objective in the optical path.
• When the micrometer is to be printed in on a
photograph, adjust the position of the slider in the
direction in which it slides until the micrometer is
located within the viewfinder photomask of the
photomicrographic attachment.
• When using a TV camera, watch the monitor screen
and adjust the position of the slider in the direction in
which it slides until the micrometer is located within
the projected area.
