Focusing and slide protection
1. Select the 4X objective and make sure that it is placed correctly in the optical path.
2. Rotate the position screw to top, observe the right eyepiece with your right eye. Rotate
the coarse focusing knob until the image appears.
3. Rotate the fine focusing knob to sharpen the image.
4. When you perform focusing with a S100X objective, you need to lock the slide protection
handle. The slide protection handle protects the slide by limiting the travel range of the
mechanical stage. This way the objectives will not touch or break your slides:
Adjusting the focusing tension
The tension of the focusing knobs can be adjusted. You can set it from light to heavy according to
your own preference. Please note that when the specimen leaves the focus plane after focusing or
the stage declines out of its own, then you need to adjust the tension.
To tighten the focusing knob (move heavy), rotate the tension adjustment ring counter-clockwise;
to loosen it, please turn it in the clockwise direction.
