The Bresser 3810030 is a precision optical instrument designed for detailed observation and measurement. This manual provides comprehensive instructions for safety, features, assembly, setup, operation, maintenance, and troubleshooting to ensure optimal performance and longevity of your device.

Features at a Glance

Key components: High-quality optical lens system, precision focusing mechanism, adjustable stand, integrated measurement scale, eyepiece, objective lens, and fine adjustment knobs.

Assembly & Installation

Unpack all components carefully and verify contents against packing list. Place on stable, level surface.

1. Assemble stand: Attach base to vertical column using provided screws.
2. Install arm and head: Secure the observation head to the arm, then attach to column.
3. Mount objectives: Place objective lenses into turret slots, ensuring they click into place.
4. Insert eyepiece: Place eyepiece into observation tube, secure with retaining ring.
5. Connect power: Plug AC adapter into power input, then connect to wall outlet.

WARNING! Handle optical components by edges only. Avoid touching glass surfaces. Ensure all screws are tightened securely but do not overtighten.

First-Time Setup

Power on the device and perform initial calibration for optimal performance.

1. Eye adjustment: Set interpupillary distance by moving eyepieces until single circular field is visible.
2. Diopter adjustment: Focus using coarse knob, then fine-tune with diopter ring on left eyepiece.
3. Illumination setup: Adjust brightness control to comfortable level for your observation.
4. Stage calibration: Center the stage and ensure smooth movement in all directions.
5. Objective alignment: Rotate turret to lowest magnification, focus on sample, check alignment.

CAUTION! Never look directly at bright light source through eyepiece. Always start with lowest magnification and lowest light intensity.
