5. s using a magnifying glass to ensure that the element is clean If immersion oil or specimen material of any kind is evident use a cotton swab dipped in a small amount of Windex to clean all foreign material from objective lens surface Such material will reduce or totally block image quality e Cleaning condenser lens Clean only the top lens surface visible when looking through hole in top of stage Use same procedure as used for eyepiece or objective lenses f Illuminator condenser lens Use same procedure as used for eyepiece or objective lenses 2 Electrical Maintenance WARNING FOR YOUR SAFETY TURN SWITCH OFF AND REMOVE PLUG FROM POWER SOURCE OUTLET BEFORE MAINTAINING YOUR MICROSCOPE 1 Replacement of Bulb a Carefully pull magnetic lamp housing up and off of the microscope to reveal the bulb b Using a tissue or cloth gently grasp the halogen bulb pull straight out of lamp socket C Your microscope requires an LED bulb available from your microscope dealer d Make certain that the new bulb is clean as fingerprints on the bulb can affect light transmission Grasping bulb gently with a tissue or cloth insert pins straight into the lamp socket e Replace magnetic lamp housing RICHTER Err ca 2 Replacement of Fuse The fuse is located on the back of the microscope on the right side of the power plug To remove the fuse from the holder insert a6mm screwdriver blade into slot located in rear of fuse cap Slight
6. t with such contaminants and image quality is reduced OPERATION A Illumination 1 Before operating microscope adjust intensity control located on side of base to the minimum position This should be done prior to each time the base is turned on or off This will extend bulb life 2 Insert power plug into base of microscope Then insert plug into outlet 3 Push rocker switch at back of the base to on position 4 Rotate intensity dial on illuminator base until the image is illuminated 5 Adjust intensity of light to match requirements of objective and specimen slide B Interpupillary Adjustment of Viewing Head 1 Looking through microscope adjust distance between the two eyepieces by grasping the eyetubes and moving them either closer or farther apart 2 When a full field of view is observed throught both tubes and images blend into one interpupillary distance is corrected for your eyes Check the interpupillary scale and note index reading for future reference in case other users will be changing this adjustment from time to time 3 Adjust the diopter scales located on each eyetube to the same numerical value as indicated on the interpupillary scale This must be done in order to maintain parfocality of objective lenses If interpupillary distance is changed adjust eyepiece diopters accordingly C Focusing the Microscope 1 Position the 4x objective lens into the optical path making sure that lens clicks into its proper
7. to another while requiring only a slight adjustment of the fine focus controls c When changing to the 40x and 100x objective lens care must be exercised in order to prevent damaging the front lens element and specimen slide d In order to obtain the maximum resolution of the 100x oil immersion lens it is necessary to apply immersion oil between the cover glass of slide and the front lens of the objective 1 Use a very small amount of immersion oil Only the tip of the lens should ever come in contact with the oil RICHTER Err ca 1 Optical Maintenance a Do not attempt to disassemble any lens component Consult an expert technical service company when repairs not covered by these instructions are required b Prior to cleaning any lens surface brush dust or dirt off lens surfaces using a camel hair brush Or use air to blow dust and lint off surfaces Compressed air available at any computer supply store is a good source of clean air C Cleaning eyepiece lenses Do not remove eyepiece from eyepiece tube Clean only the outer surface Breathe on lens to dampen surface then wipe with lens paper Do not wipe lens surface while dry as lenses are scratched very easily Wipe in a circular motion from center to outer edges d Cleaning objective lenses Do not remove objective lenses from the microscope Clean front lens element only Using a cotton swab saturated with distilled water clean front lens surface Inspect the len
