Choosing a place for the microscope

Before starting, choose a sufficient location for microscopy. Please take care that your microscope stands on even and solid ground.
Position your device so that it can be disconnected from the power supply at any time. The wall socket should always be located near the device and be easily accessible since the plug on the power cord serves as a disconnecting device for the power supply.

Illumination

With the Analyth STR you have three illumination options: incident light, transmission light, and both. First, connect the power supply to a power supply socket and then into the power supply connection of the microscope (14). Now, engage the main switch (6).
The illumination for incident light and transmitted light can be adjusted separately by using the two brightness control buttons (7 and 8). After switching off, the selected setting is retained.
Alternatively, the Analyst STR can also be operated with batteries. To insert the batteries (type AA), open the battery compartment (13) on the underside of the microscope.
Make sure that the polarity is correct. The microscope can also be used with the power supply when batteries are inserted. Rechargeable batteries will not be charged.

Observation

Place the desired object in the middle of the stage (10) and secure it with the clamps (11) if necessary. The objective’s magnification (1x, 2x, or 4x) can be adjusted by turning the objective holder (12). It is recommended to start observations always with the lowest magnification (1x). Now, look through the eyepieces (1) at the binocular head (3). Adjust the sharpness with the focuser (4).

Focusing and dioptre compensation

Set the dioptre scale (2) to to the middle position (shiny ring) and observe an object. Now close your left eye and adjust the focus with the focuser (4) for your right eye. Then, close your right eye and adjust the focus for your left eye with the dioptre scale. Now, the microscope is adjusted for your eyes. Note the setting of the dioptre scale you need to use in the future.

Eye distance

The Analyth STR is equipped with an adjustable binocular head. To set your eye distance, move the eyepieces against each other until you found the ideal position.

Replacing the Eyepieces (optional)

To replace the eyepieces you need to loosen the clamp screw on the underside of the eyepiece holder. You can then easily remove and replace the eyepieces.
The clamp screws serve only as protection so that the eyepieces will not fall out.
Note:
The LED illumination has a life span of approx. 20,000 hours. In the case of a technical error please contact the service center.

Adjusting the friction of the focusing drive

It can happen that the Microscope head is no longer held by the focusing drive and shuts down because of his net weight.
By turning the two focusing wheels in opposite directions, the friction can be adjusted more firmly or loosely.

Cleaning and maintenance

Your microscope is a high-quality optical instrument. Please take care that neither dust nor fingerprints take place on the optical surfaces. If necessary, clean the microscope body with a slightly moistened soft cloth. Use a separate clean cloth with some drops of alcohol to clean the optical surfaces. After use, the microscope should be protected with its dust cover.
Note:
Please consider that a sufficient treated microscope keeps its value and optical quality for many years.
