Open the box carefully to avoid the accessories, like lens, dropping to ground or being damaged. 2. Do keep the instrument out of direct sunlight, high temperature or humidity, dusty and easy shaking environment. Make sure the stage is flat, horizontal and firm enough. 3. When moving the microscope, carefully carry it with the handle and the base. 4. Make sure the instrument is earthed, to avoid lighting strike. 5. For safety, be sure the main switch is in “O” (off) state and cut off the power supply before replacing the bulb or the fuse. If you replace the bulb during use or right after use, allow the lamp bulb and the lamp house to cool completely before touching. (Designated bulb: 1W S-LED or 6V20W Halogen Lamp) 6. Check the input voltage: be sure the input voltage which is signed in the back of the microscope is consistent with the power supply voltage, or it will bring a serious damage to the instrument. 7. Always use the power cord provided by Gima. 8. The electrical equipment of the microscope should be discard as electronic waste. Maintenance and Care 1. All the lenses have been adjusted properly; do not dismount them by yourself please. 2. The nosepiece and coarse and fine focusing parts are so delicate that it is forbidden to disassemble them carelessly by yourself. 3. Keep the instrument clean, and do not pollute the optical element when wiping away the dust on the instrument. 4. The contaminations on the prism, like fingerprints and oil smudges, could be gently wiped with a piece of soft cloth or tissue paper, gauze which has been immersed in pure alcohol or ether. (Note that the alcohol and ether are highly flammable, do keep them away from the fire or potential sources of electrical sparks, and use them in a drafty room as possible as you can.) 5. Do not attempt to use organic solvents to clean the microscope components other than the glass components. To clean them, use a lint-free, soft cloth slightly moistened with a diluted neutral detergent. 6. When using, if the microscope is splashed by liquid, cut off the power at once, and wipe away the splash. 7. Do not disassemble any parts of the microscope, as this will affect the function or reduce the performance of the microscope. 8. Place the instrument in a cool, dry position. When not using the microscope, keep it covered with a dust cover. Make sure the lamp socket is cool before covering the microscope. ENGLISH Assembly procedure Before installing, be sure every components is clean, do not score any parts or glass surface. Keep well with hexagon wrench provided. When changing the components, you will need it again. Installing binocular viewing head Insert the binocular viewing head 12 into the microscope head and turn it to a proper position, then tight it. 12 Installing the eyepiece Insert the eyepiece 01 into the eyepiece tube until they are against each other. 01 ENGLISH Installing the objective 1. Adjusting the coarse focus knob until the support device of the mechanical stage reaches its low limit position. 2. Screw the lowest magnification objective 03 into the nosepiece 02 from the left or the right side, then revolve the nosepiece 02 clockwise and mount other objectives by the sequence of low to high magnification Installing objective this way will make the change of magnification to be easier during using. Clean the objective regularly, for lens is susceptible to dust. When operating, use 10× magnification objective to search and focus specimen firstly, then replace with higher magnification objective if necessary. When replacing the objective, slowly turn the nosepiece until you hear “clicked”, that means the objective is in place. 02 03 Connecting the Power Cord The cable and cords are vulnerable when bent or twisted, never subject the power cord to excessive force. 1. Set the main switch 08 to “0” (off) state before connecting the power cable 22. 2. Insert the plugs into the power jack 27 of the microscope safely. 3. Plug the power cable 22 into the power supply receptacle. Make sure the connection is well. 08 22 Do use the supplied power cord all the time. If lost or damaged, select the same standard cord, please. A wide range of voltage, like 100V~240V, is acceptable for this microscope. 27 ENGLISH Replacing the fuse Do remember to set the main switch 08 to the state “0” (OFF) and unplug the power cord before replacing the fuse. Rotate the fuse out of the holder 27, replace with a new fuse, then rotate it back to the holder again. Installing and Replacing the bulb Please use the specified lamp. 1. Loosing the screw 10 2. Hold the bulb 09 after you wrap it with gauze or other protection materials, and then insert its pin deeply into the jack in the lamp holder. 3. During microscope using or soon after it is turned off, the bulb, the lamp house and nearby parts will be very hot and will cause serious burns. Please turn the main switch to “0” (off) and disconnect the power plug, and make sure the bulb, the lamp room and periphery are all cool. Then, you can do your replacing. 09 10 Insert the bulb gently. Squeezing too hard will damage the bulb. To prevent reduced bulb life or cracking, do not touch the bulb with bare hands. If fingerprints are accidentally left on the bulb, wipe the bulb with a soft cloth. Adjustment and Operation Brightness Adjustment 1. Connect the power cord and set the main switch 08 to “ I ”state (ON). 2. Turning the brightness adjustment knob 26. 26 Placing the Specimen 1. Place the specimen the center of the mechanical stage and use the stage clips to clamp it. 2. Turn the portrait 14 and lateral adjustment knob 15 of the mechanical ruler, move the specimen to the required position. Be careful when changing the objective. If you finish the observation with the short working distance objective, and want to change another one, becareful of not letting the objective touch the specimen. 14 15 ENGLISH Focusing the Specimen 1. Focus the specimen with 10x objective. To avoid the objective touching the specimen during focusing, you should raise the mechanical stage to let the specimen close to the objective at first, then slowly separate them to bring the specimen to focus. Turn the coarse focus knob 25 conversely to lower the specimen and search images in the 24 10×ocular simultaneously, and thenuse the fine 25 23 knob 24 to focus. After that, you can replace with other magnification objectives safely, and focus without the risk of damaging the specimen. To make the observation more convenient, you can use the locking set 23 to fix the stage in a vertical direction. Condenser Adjustment Turn the condenser focus knob 20 to move the condenser up and down. Raise the condenser when using the high magnification objective, and descend it when using the low magnification one. 21 20 1. Focus the specimen with 10x objective. 2. Adjust the condenser focus knob 20 to get a clear image of the field iris diaphragm. 3. Turn the condenser centering knobs 21 to center the image of field iris diaphragm in the field of view. The condenser and the objectiveare coaxial. It has been adjusted before leaving factory, so the user needn’t to adjust them by self The highest position of the condenser has been adjusted too. It also needn’t any user’s operation. (The top surface of the condenser is 0.03 mm - 0.4 mm lower than the stage top surface.) Aperture Iris Diaphragm Adjustment Turn the aperture iris diaphragm stick 05 to adjust the aperture iris diaphragm. The aperture iris diaphragm is designed for the adjustment of the numerical aperture,not for the brightness. Generally, setting the aperture iris diaphragm to 70- 80% of the N.A. of the objective in use will provide an image with good contrast. If you want to observe the image of the aperture iris diaphragm, remove one eyepiece and look through the tube. You will see a dark circle encroaching on the bottom of the tube. 05 ENGLISH Adjusting the Interpupillary Distance The interpupillary distance range: 55mm ~ 75mm While looking through the eyepieces, move both eyepieces round until the left and right fields of view coincide completely. Adjusting the Diopter 1. Turn the eyepiece 01 to adjust the diopter while looking through it. The diopter range of the eyepiece is±5 diopter. The number aligned to the line on the viewing head is the diopter in use. Adjusting the tension adjustment collar Turn the tension adjustment collar 18 with your fingers. When the collar is turned in the direction of the arrow, the tension of the coarse adjustment knob 17 increases. Turning the collar in the opposite direction decreases the tension. If the nosepiece descends on its own or if the specimen gets out of focus quickly even when it is brought into focus using the fine adjustment knob 16, it means the tension of the coarse adjustment knob is too low. Turn the collar in the direction of the arrow to increase the tension. 01 18 16 17 ENGLISH Technical Specifications Main Specifications Optical System Viewing Head Limited optical system/Infinite optical system Seidentopf Binocular Head, 30°Inclined,Interpupillary Distance 4875 mm WF 10X/18 WF 10X/20 Backward Quadruple Nosepiece Achromatic Objective/Infinite Semi-plan Objective 4×, 10×, 40×, 100× Coaxial Coarse and Fine Adjustment, Moving Range 0.002mm <,Fine Division 20mm Abbe Condenser, NA1.25 Double Layers Mechanical Stage160×140, Moving Range74×50 Timing Belt Stage150×139mm, Moving Range 75×52mm 1W S-LED Lamp Eyepiece Nosepiece Objective Focusing Condenser Stage Illumination Eyepiece and objectives Achromatic Objective Magnification 4× 10× 40× 100× Numerical Aperture NA 0.10 0.25 0.65 1.25 Focal Length Focal distance Working (mm) (mm) Length (mm) 0.17 31.05 37.5 0.17 17.13 7.316 0.17 4.65 0.632 0.17 2.906 0.198 Objective Focal Length Focal distance Working (mm) (mm) Length (mm) 0.17 45 16.8 0.17 18 5.8 0.17 4.5 1.43 0.17 1.8 0.13 Objective dry dry dry oil Infinite Semi-plan Objective Magnification 4× 10× 40× 100× Numerical Aperture NA 0.10 0.25 0.65 1.25 dry dry dry oil Eyepiece Eyepiece Wide field eyepiece Wide field eyepiece Magnification 10× 10× Focal Length (mm) 24.95 25 Field of View (mm) Φ18 Φ20 Total Magnification Eyepiece Objective Total Magnification 10× 4× 40× 10× 10× 100× 10× 40× 400× 10× 100× 1000× ENGLISH Troubleshooting Guide Optical System TROUBLE 1.
