Manual This manual expatiates the using method, troubleshooting and maintenance about MT-40 series biological microscope. Please study this manual thoroughly before operating, and keep it with the instrument. The manufacturer reserves the rights to the modifications by technology development. On the basis of operation...
Before Use MT-40 Series 1. Operation Notice 1. As the microscope is a high precision instrument, always operate it with care, and avoid physical shake during the operation. 2. Do not expose the microscope in the sun directly, either not in the high temperature, damp, dust or acute shake.

MT-40 Series 2. Maintenance 1. Wipe the lens gently with a soft tissue. Carefully wipe off the oil marks and fingerprints on the lens surfaces with a tissue moistened with a small amount of 3:7 mixture of alcohol and ether or dimethylbenzene.
2. Assembling MT-40 Series 2-1 Assembling Scheme Following is the Assembling Scheme, and the numbers denote the assembling order. ★ Before assembling, make sure there is no dust or dirt. Assemble carefully and do not scrap any part or touch the glass surface.
MT-40 Series 2-2 Assembling Steps 2-2-1 Assemble the Condenser 1. Rotate the coarse focusing knob① to raise the stage to the highest position (see Fig. 3). 2. Rotate the condenser up-down knob② to lower the bracket of condenser to the suitable position.

MT-40 Series 2-2-3 Assemble the Eyepiece 1. Take down the cover of eyepiece tube . ① 2. Insert the eyepiece② into the eyepiece tube, until touch the surface (see Fig. 5). 2-2-4 Connect the Power Cord Fig. 5 ★ Don’t use strong force when the power cord is bended or twisted, otherwise it will be damaged.
3. Operation MT-40 Series 3-1 Set Illumination 1. Put through the power and turn on the main power switch to“—”. 2. Adjust the light adjustment knob until the ① illumination is comfortable for observation. Rotate the light adjustment knob clockwise to raise the voltage and brightness.
MT-40 Series 3-3 Adjust the Focus 1. Move the objective 4X to the light path. 2. Observe the right eyepiece with right eye. Rotate the coarse focusing knob until the ① image appears (see Fig. 10). 3. Rotate the fine focusing knob③ for clear details.
MT-40 Series 3-6 Adjust the Field Diaphragm (Iris Diaphragm Koehler Illuminator Condenser Optional) By limiting the diameter of the beam entering the condenser, the field diaphragm can prevent other light and strengthen the image contrast. When the image is just on the edge of the field of view, the objective can show the best performance and obtain the clearest image.
M T - 4 0 Series 3-8 Use the Oil Objective (100X) 1. Use objective 4X to focus the specimen. 2. Place a drop of oil ① on the specimen (see Fig. 15). 3. Rotate the nosepiece counterclockwise and rotate the oil objective (100X) to the light path.
MT-40 Series 3-10 Replace the Fuse Turn the main switch to “0” (OFF) before replacing the fuse. Pull out the power cord. Then screw off the fuse group from the fuse base ① ② with a “-” type screwdriver. Install a new fuse and screw it on the fuse base (see Fig.
4. Technical Specifications MT-40 Series 4-1 MT-40 Series Biological Microscope Technical Parameters Optical system UIS (universal infinity-corrected optical system) Head Binocular head of Gemel type, 30° inclined Eyepiece PL10X18T diopter adjustable eyepiece, 18mm line field of view Nosepiece Reversed quadruple nosepiece Infinity Plan achromatic objective(4X, 10X, 40X, 100X)...
5. Troubleshooting MT-40 Series As the performance of microscope can’t play fully due to unfamiliar operations, the table below can provide some solutions. Problem Cause Solution 1. Optical Part (1) The LED light Field diaphragm is not large enough. Enlarge the field diaphragm.
