Ratchet Steps and Magnification Levels

The zoom button can optionally be operated either with or without ratchet steps. Continu- ous zoom is possible when the ratchet steps are disabled, which many users find convenient. On the other hand, when the ratchet steps are enabled, photographs, measurement results etc. can be reproduced more accurately.

Enabling and disabling ratchet steps

1.Push the button towards the knob to enable the ratchet steps.

2.Push the button away from the knob to disable the ratchet steps.

Magnifications and fields of view

The formula on page 62 provide additional information about the magnifications and field of view diameters, with consideration given to the position of the magnification changer and the eyepiece and objective combination used.
