General/Location

First you must make sure that your microscope is on a stable and solid surface.

Electric LED lighting with dimmer

In the base of the microscope, there is a battery compartment (12). Loosen the screws at the battery compartment cover with a small screwdriver and remove the cover. Place the batteries in the compartment so that the flat minus poles (-) press against the spring terminal and the plus poles (+) are touching the flat contact sheets. Close the battery compartment with the cover and turn the microscope around again. As your device has continuously controllable lighting (dimmer) optimal illumination of the object to be viewed is guaranteed.

Microscope setup

The microscope’s eyepiece will now be prepared for the first observation. First, rotate the eyepiece into a convenient position. Begin every observation with the lowest magnification. Place the microscope stage (Fig. 1, 7) with the focus wheel (Fig 1, 8) into the lowest position and rotate the objective revolver (Fig. 1, 6) until it locks on the lowest magnification (4x).

NOTE:
First, drive the Microscope’s table (Fig. 1, 7) in its lowest position before changing the objective in order to prevent damage.

Insert the 5x eyepiece (Fig. 3, 1) in the Barlow lens (Fig. 3, 3). Take care, that the Barlow lens is inserted completely in the eyepiece socket (Fig. 3, 4).

Condenser

The condenser is used to adjust the light bundling to the observed object in an optimal way. The iris diaphragm is used to increase the depth of focus. With an open aperture more light is getting through but the depth of focus is less. With a partially closed aperture the depth of focus is higher but it is necessary to increase the brightness of the illumination then. It is recommended not to close the iris diaphragm too much when working with higher magnifications. Otherwise, the image resolution will decrease. Move the lever for the iris diaphragm to right or left to change the aperture setting.

Observation

After you have set up the microscope with the corresponding illumination, the following principles are important:

Begin each observation with a simple observation at the lowest magnification, so that the center and position of the object to be viewed is in focus.
The higher the magnification the more light is required for good picture quality.
Place a permanent slide culture (Fig. 4) directly under the microscope lens on the plate (Fig. 4, 7) and clamp it tight. The specimen to be examined must be directly over the lighting.
Look through the eyepiece (Fig. 1, 1/2) and turn carefully the focusing wheel (Fig. 1, 8) until you can see a sharp picture.
Now you can get a higher magnification, while you pull out slowly the Barlow lens (Fig. 5, 3) of the eyepiece socket (Fig. 5, 4). With a nearly entirely pulled-out Barlow lens the magnification is raised to 2x.
For still higher magnification you can put the 16x eyepiece (Fig. 5, 2) into the objective revolver (Fig. 1, 6) and set it on a higher position (10x / 40x).

TIP:
Depending on the preparation higher magnifications do not always lead to better pictures.

With changing magnification (eyepiece or objective lens changes, pulling out of the Barlow lens) the sharpness of the image must be newly defined by turning the focusing wheel (Fig. 1, 8).

NOTE:
Please be very careful when doing this. When you move the mechanical plate upwards to fast the objective lens and the slide can touch and become damaged.

Viewed Object condition and preparation

Condition

With the Barlow lens nearly fully extended magnification can be doubled. Both transparent and non-transparent specimens can be examined with this microscope, which is a transmitted light model. If translucent (transparent) specimens are examined the light from below goes through the specimen, lens, and eyepiece to the eye and is magnified en route. Many small organisms of the water, plant parts and finest animal components have now from nature this transparent characteristic, other ones must be accordingly prepared. Is it that we make it by means of a pre-treatment or penetration with suitable materials (media) transparent or thus that we cut the finest wafers off of them (hand cut, MicroCut) and these then examine? With these methods will us the following part make familiar.

Creation of thin preparation cuts

Specimens should be sliced as thin as possible, as stated before. A little wax or paraffin is need-ed to achieve the best results. A candle can be used for the purpose. The wax is put in a bowl and heated over a flame. The specimen is then dipped several times in the liquid wax. The wax is finally allowed to harden. Use a MicroCut or knife/scalpel (carefully) to make very thin slic-es of the object in its wax casing.

DANGER!
Be extremely careful when using the knives/scalpels or the MicroCut. There is an increased risk of injury due to the sharp edges!

These slices are then laid on a glass slide and covered with another.

Creation of an own preparation

Put the object which shall be observed on a glass slide and give with a pipette (Fig. 6, 17a) a drop of distilled water on the object (Fig. 6). Set a cover glass (in each well sorted hobby shop available) perpendicularly at the edge of the water drop, so that the water runs along the cover glass edge (Fig. 7). Lower now the cover glass slowly over the water drop.

Care and maintenance

Separate the device from the power supply before cleaning (remove batteries)! Only use a dry cloth to clean the exterior of the device.

NOTE:
Do not use any cleaning fluid to avoid damaging the electronics.

Clean the lenses (eyepiece and/or lens) with a soft and lint-free cloth only (e.g. microfibre).

NOTE:
Do not apply excess pressure to the cloth so as to avoid scratching the lenses.

To remove more stubborn dirt, moisten the cleaning cloth with an eyeglass- cleaning solution and wipe the lenses gently.

Protect the device from dust and moisture! After use – in particular in situations of high humidity – let the device acclimatize for a short period of time so that the residual moisture can dissipate.

As per Directive 2002/96/EC of the European Parliament on waste electrical and electronic equipment and its adaptation into German law, used electronic devices must be collected separately and recycled in an environmentally friendly manner. In accordance with the regulations concerning batteries and rechargeable batteries, disposing of them in normal household waste is explicitly forbidden. Please make sure to dispose of your used batteries as required by law — at a local collection point or in the retail market. Disposal in domestic waste violates the Battery Directive.
