it with care, avoiding impact or abrupt movement during transportation. 2. MAINTENANCE (1.) All glass surfaces must always be kept clean. Fine dust on the optical surface should be blown off by means of a hand blower or gently wiped off with a soft lens tissue. Carefully wipe off oil or fingerprints on the lens surfaces with tissue moistened with a small amount of 3:7 mixture of alcohol and ether. (2.) Do not use organic solution to wipe the surface of the other components. These parts, especially the plastic parts, should be cleaned with a neutral detergent. (3.) Do not take down or assemble it yourself. (4.) After use, cover the microscope with the dustcover provided, and keep it in a dry and clean place for preventing rust. (2.) Do not let the microscope BE in the sunlight directly. Keep it in a dry and clean place. Avoid high temperature and acute shaking. Following environment is required: Indoor temperature: 0°C~40°C, Max relative humidity: 85%. (3.) Avoiding impact the definition of the image, do not leave feculence and fingerprints on the lens surfaces. (4.) Before using, examine to ensure that the power supply voltage is consistent with the rating voltage. 1 WESTLAB EXTREME MONOCULAR MICROSCOPE, RECHARGEABLE, LED USER MANUAL CODE 663-540 & 664-089 BEFORE USE

First take the container out of the carton, and lay the container on its side. Open the container carefully and don’t let the optical items drop down, avoiding them being damaged. Check carefully to ensure the arm and accessories are intact. Install the objective into the microscope nosepiece from the lowest magnification to the highest, in a clockwise direction from the rear. Insert the eyepiece into the eyepiece tube. 2-1 Set the specimen slide Place the specimen to be studied on a glass slide, and fix it with the slide-holder of the mechanical stage. If we use the movable specimen holder, fix the specimen by slide-holder of the movable specimen holder. Adjust its position by the switch of the movable specimen holder. 2-2 Set illumination 2-3 Adjust focus Adjust the coarse-focusing-knob to bring the slide into focus. Then lock the limit-stop-screw to avoid impact between the objective and slide. Adjust the fine-focusing-knob to get the image sharper and clearer. 2-4 Adjust diaphragm Turn the disc diaphragm to select a aperture to get the background brightness suitable. 2-5 Choose the objective 3 Turn the nosepiece to choose the objective. Objective selected should be set vertically right to the slide. Generally, first use the objective 4X to focus to reveal general structural image. Then use the high power objective to reveal smaller details. 2-6 Change the lamp Before changing the lamp, first pull the plug out off the electrical socket and wait for a while until the lamp cools down to avoid being burnt. Then screw off the base lens in an anti-clockwise direction and insert a new lamp and screw on the base lens. For the microscope with built-in electrical illuminator, insert the plug of the main cable into the power socket and turn on the light switch to get the specimen illuminated. 2.

4-5 TECHNICAL TERMS (1) Total magnification=(magnification of objective) X (magnification of eyepiece) (2) Field of view=(line field of view of the eyepiece selected) ÷(magnification of the objective selected) (3) N.A.=n·sinα (max), N.A.is very important parameter which marks the features of the objective and condenser. The “n” is the refractive index of the medium (air or immersion oil) between the cover glass of the objective and the specimen. The “α” is the half of the aperture angle. The N.A.is bigger, the resolution of the objective is higher. (4) Object to primary image distance: the distance between the object plane to the primary image plane. The conjugate distance is fixed. (5) Mechanical tube length: The distance between the objective shoulder and the ocular shoulder. WESTLAB EXTREME MONOCULAR MICROSCOPE, RECHARGEABLE, LED USER MANUAL CODE 663-540 & 664-089
