can be engaged for certain magnifications (see below).

Changing the magnification

• The magnification changer can be operated from either the
right or the left.

• Engage the ratchets whenever magnifications need to be
exactly reproducible.

Look into the eyepieces.
Focus on the object (page 11).
Turn the magnification changer
to the position required.
For MZ6, MZ9 , MZ12 and

anticlockwise.
Scale of magnifications
MS5, MZ6
Display of magnification factors from 0.63 – 4.
MZ7
5
Display of magnification factors from 0.63 – 5. For other objective-
eyepiece combinations, appropriate adhesive scales can be
applied to the rotary knobs (page 19).
MZ9
5
Display of magnification factors from 0.63 – 6.
MZ12
5
Display of magnification factors from 0.8 – 10.
MZAPO
Display of magnifications with various optical combinations,
e.g. with 1.0 objective and 10 eyepieces: 8 – 80 .
MZAPO: Setting the scale
The magnification scale can be set in accordance with the
optical combination.
Example:
1.0 objective / 25 eyepiece
Magnifications and fields of view
The tables between page 41 and page 43 provide information
about the magnifications and field diameters as a function
of the magnification changer position of the eyepiece-objective
combination used.
Turn the magnification changer
to the stop at its lowest magnifi-
cation position.
Read the magnification range
from the table on page 43 (in the
example given, 20 to 200 ).
Place a finger in the rear
window of the magnification
changer and displace the
scale so that the position 20
is lined up with the index.
