Click Stops and Magnifications

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

Enabling and disabling click stops

1.Push the top button downwards to disable the ratchet steps.

2.Push the bottom button upwards to enable the ratchet steps.
