Intended use of the microscope
The LED Microscope is particularly designed for teaching pupils microscopic viewing. It is a scientific device and not a toy.
Directions for use
a) Preparation: Setting up the microscope
Take the microscope out of its Styrofoam wrapping and put it onto a stable and level working surface.
b) Work Instructions
Illumination
The LED Microscope is equipped with LED lights. The electricity for the lighting is stored in rechargeable batteries. The light
of the LED bulbs hardly heats liquid specimens. This bulb has an average operating time of 100 000 working hours. The
lighting is switched on at the back of the base. The rechargeable batteries are best recharged overnight.
Power supply
The LED Microscope works with rechargeable batteries. One battery charge lasts for about 10 operating hours. The included
recharger can only be connected to a power circuit of 220 Volt. The recharger is protected against overcharging. First
connect the recharger to the microscope, and then connect it to the power circuit. Should the rechargeable batteries totally
be discharged, please recharge them overnight. The batteries can only be recharged when the microscope is switched off.
Should the rechargeable batteries be defective and need to be exchanged, please contact the place of purchase.
Placing the microscope slide
Place the specimen holder provided with a sample object onto the microscope stage (size 9,5 x 9,5 cm), and fasten it careful-
ly with the help of the flexible spring clips. By moving the specimen in different directions, various parts can be viewed.
Adjusting the image sharpness
Start by viewing your object with a four times magnification. Turn the knob for coarse adjusting until you receive a clear
picture. Proceed the same way with every other object. Pay attention that the object does not touch the objective lens. In
order to avoid damage to the objective lens or to the specimen preparation, the microscope is equipped with a specimen
protection. This prevents the stage from being turned up too far and thus the objective lens pressing onto the object. The
specimen protection is already adjusted correctly, but – if necessary – can be readjusted with the screw on the top side of the
stage. Furthermore, the 40x objective is spring loaded, to avoid the specimen being pressed.
Regulating the light intensity
The luminance can be adjusted through the different openings of the aperture plate. Light influences the viewing quality,
especially with high magnification.
Changing the objective
When you reached the optimal top view with the smallest magnification (4x), turn the objective lens piece to the next magni-
fication (10x). The objective lens piece should click into position. Only a slight adjustment should be necessary, to receive a
clear picture again. Should you increase the magnification further; the top view will be improved by adjusting the light.
