Product Usage Instructions

Attention: Do not disassemble and uninstall any accessories unless instructed to do so in the manual. Disassembling and uninstalling freely may result in electronic shock and damage to the instrument.
Check the Voltage:
The fixed input voltage is marked on the microscope base. Ensure that the local voltage supply matches the marked voltage. If not, consult an experienced professional to adjust the power switch or contact the factory directly.
The power socket should have an earth wire.
During illumination, the bulbs and the illuminator may get hot. Avoid touching them to prevent skin burns.
Keep the microscope covered with a dust cover when not in use and avoid disposing of it near dirt.
Place the microscope in a shaking-proof location.
Operating Carefully:
The microscope is a sophisticated optic instrument. Avoid shaking heavily and operating rigidly to prevent damage.
Do not reverse the left and right coarse focusing knob to maintain precision in focusing.
Avoid touching the surface of the optic accessories to prevent image blurring.
Installation:
Fix the stand on the worktable using the ‘G’ shape clamp.
Secure the main body on the stand using the joint dowel and screw cap. Place the dustproof cover on the main body.
Adjust the main body to a proper position for viewing and tighten the tightening screw. Mount the objectives onto the nosepiece.
Mounting and Changing Lamps: Follow the instructions provided in the manual for mounting and changing lamps.

Safety Instruction

Attention

NO disassembling and uninstall
It is easy to get an electronic shock and damage the instrument if disassemble and uninstall freely. Please do not disassemble and uninstall any other accessories freely except that the instruction mentions they could be disassembled and uninstalled.
Check the voltage
The fixed input voltage is marked on the microscope base. Please attention that the local voltage supply must be accord with it. Or else dismantle the base by the experienced professional, adjust the power switch marking 110V,220V to be in accordance with the local voltage, and then install the base; or you can also contact the factory directly. The microscope must be used within the rated voltage, otherwise it would be damaged badly.
The power socket should have earth wire.
Anti-Fire and Scald
During illumination, the bulbs and the illuminator are easy to get hot. Attention not to touch them in order to avoid hurting the skin.
To change the bulb must be after it is completely cool down.
The easy-burning substance must be kept away from the bulb in order not to get burn.
Change Lamp
Before change the bulb, switch off the power supply and pull out the plug of electrical wire to avoid getting an electrical shock and damaging the instrument.
Use the specific halogen bulb, 12V20W.
Change the bulb with gloves or wrap the bulbs with the protective cover. Don’t touch the glass of the bulb directly. Then erase the fingerprint and spots with the alcohol. Otherwise the bulb is easy to get split and weaken the brightness.
Move and Dispose
Switch off the power supply before move the instrument.
Moving and disposing environment requirement:
Environment temperature:-40°C～+55°C
The maximum relative humidity:95%
Avoid disposing the instrument in the sun or the room lights. The bright environment affects the quality of the image.
Don’t dispose with dirt around. When not use, cover it by dust cover.
The place must be shaking-proof when dispose.
Working Environment
Indoor temperature:0°～C40
The maximum relative humidity:85%
Running mode: continuous
Operating Carefully
The microscope is sophisticated optic instrument. Shaking heavily and operating rigidly will damage the instrument deadly. Don’t reverse the left and right coarse focusing knob. Otherwise, the focusing will lost its precision. 2)Don’t touch the surface of the optic accessories or else the image would be blur.

Uses

Operation

Installation:
Take out the stand (3) from the packing box and fix it on the worktable by the ‘G’ shape clamp. Take out the main body (8) from the other package and secure it on the stand (3) using the joint dowel (5) and screwing the screw cap (4) tightened. Then put the dustproof cover (7) in place on the main body (8) Turn the main body to a proper position for viewing and tighten the tightening screw (2), then mount the objectives onto the nosepiece.

Mounting and changing the lamps:
Before using the microscope, please first mount the lamps. Gently press the finger-shape protrusion on the protective baffle (12) and take out the protective baffle (12) from the illuminating hole, insert the lamp straight into the socket as far as it will go. Only use halogen lamps of the specified rating. Replace the protective baffle (12), Do not touch the glass part of a lamp with your bare hands as your fingerprints may stick to the lamp, possibly reducing its level of light output or causing damage to the lamp.
When changing the lamps, please pull down the plug of the electrical wire before changing it. Change the lamp after it is cool enough. Press the finger- shape protrusion on the protective baffle (12) lightly and take out the protective baffle (12) from the illuminating hole. Replace the bulb with the new one; then remount the protective baffle (12) into the illuminating hole. During changing the bulb, note not to directly touch the glass portion of the bulb and the protective baffle by hand but to wear glove or use sheath. After finishing, wipe off the fingerprint and smudge on the glass with the soft clean cloth dampened with absolute alcohol. Otherwise the bulb is easy to get split and weaken the brightness of the whole illumination system.

Checking the input voltage:
The rated input voltage is indicated in the electric nameplate attached to the back of the arm. In the case of the voltage of the local power supply according with the rated value, connect up the power supply. The electric socket must have earthing.

Adjusting the illumination:
The illumination consists of two halogen lamps with cup which form an angle tilting each other. Rotate the knob for adjusting the illumination (9) to change the angle tilting each other so as to get the ideal condition of illuminating.

Selecting the objectives magnification:
The microscope is equipped with various objectives for 2×,4×,6×,8×,10×magnification. The objective with the lower magnification takes on the larger field of view and depth of field. In order to find the object easily, advise to use first the lower magnification objective; then rotate the nosepiece for 120 degrees to change the objective magnification.

Adjusting the interpapillary distance:
According to the interpapillary distance of viewers, rotate the knob for adjusting the interpapillary distance (7) to assure that the beams emerging from the microscope coincide with the eyes of the viewer. The images in the left eye and right eye of the viewer concentrate into a sharp image.

Focusing :
Viewing the object by the eyepiece with uplifting or driving down the main body gently, then get a clearer and sharper image. Rotate the knob for adjusting the interpapillary distance (7) to make the beams from the microscope coincide with the pupils of the viewers, and then get an ideal magnified image.

Maintenance

Not using the microscope:
Pull out the plug of power supply wire and cover the instrument with the dustproof cover, then keep it in a dry and cool place.

Cleaning the lens:
Don’t touch the optical parts by hand.
Had better clean out the dust with the soft brush or gauze.
For stubborn smudge, such as fingerprint and lipid, etc, gently wipe it off with the clean soft cloth or lens paper dampened with the mixture of absolute alcohol and ether.

Cleaning the plastic surface and metal paint surface:
Don’t use any diluter (such as thinner, etc.) to clean the surfaces. If there are some smudges on the surfaces,
wipe it off by the gauze. For the obstinate smudges, suggest using the soft cleanser to clean
For the plastic surfaces, only can use the soft cloth dampened with water to clean. With the technology development, we maintain the right to do some improvement. So the book can not completely express the machine characteristic.
