(The nosepiece address 1 is the lowest magnification and the nosepiece address 5 is the highest magnification.) Limitation in selecting an objective The following limitation can be applied to the operation of the motorized nosepiece with the “LVDAF Setup” software. • You can disable the rotation of the nosepiece not to change objectives from a low magnification objective 5x or lower to a high magnification objective of short working distance less than 1 mm. 24 V. Operation 5 AF Offset Function After focusing on the specimen with the auto focus function, focal position can be shifted with remained in the auto focus function. This operation is called “AF offset”. The offset value of each magnification (each address of the motorized nosepiece) can be registered. To perform the “AF offset” function, press the ON button of the AF OFFSET control panel and light up the indicator after focusing on the specimen with the auto focus function. Operation of the “AF OFFSET” On/Off Then, operate + / – button of the AF OFFSET control panel to move the elevating section of the motorized focusing module so that the focal position can be moved. Operation Elevating Section Objective + button Up The objective moves farther from the specimen. – button Down The objective moves closer to the specimen. To turn off the auto focus function, press the ON button again and turn off the indicator. When the “AF offset” function is turned off, the offset values are reset. Note the followings: When the indicator is lit and the specimen is in focus, the AF offset function is running. When the AF offset function is running, the performance of auto focus will be less good than the normal condition. 25 6 Search Function If the specimen does not come into focus with the auto focus function after manual focusing or such operation, execute the search function to search a focusing position automatically. The search function has “Single mode” and “Continuous mode.” Execution of the search function Single mode On this mode, the search function ends when a focusing position is found. To invoke the single mode, press the ON button in the SEARCH control panel while the DISABLE indicator in the AUTO FOCUS control panel is lit. The indicator in the SEARCH control panel turns on. When the search function starts, the motorized focusing module moves upward and searches a focusing position. When a focusing position is found, the search function ends. If no focusing position is found, the DISABLE indicator in the AUTO FOCUS control panel turns on. Continuous mode On this mode, the auto focus function starts automatically when a focusing position is found. To invoke the continuous mode, press the ON button in the AUTO FOCUS control panel while the DISABLE indicator in the AUTO FOCUS control panel is lit. The AF indicator in the AUTO FOCUS control panel turns on. And then, press the ON button in the SEARCH control panel. The indicator in the SEARCH control panel turns on. When the search function starts, the motorized focusing module moves upward and searches a focusing position. When a focusing position is found, the auto focus function automatically starts. If no focusing position is found, the DISABLE indicator in the AUTO FOCUS control panel turns on. In the initial setting, the motorized focusing module moves only in the upward direction. But if the focusing position cannot be searched even when the module moves to the upper limit position, the module can be set to move in the downward direction. Additionally, when the module is set to move in the downward direction, be careful of a collision of the objective with the specimen. To prevent the collision, set up the software limit with “LV-DAF Setup” in the provided CD-ROM. 26 V. Operation Manual Focusing Operation of the manual focusing By operating the + / – button of the FOCUS control panel, the indicator is lit and then the elevating section of the motorized focusing module can be moved manually. To change the focusing mode between the fine focusing and the coarse focusing, press the FINE buttom. In the fine focusing mode, the FINE indicator turns on. In the coarse focusing mode, the indicator turns off. CA LED UT AV ION OIF RA DIA EX PO TIO Vo LE 3b BE OP kun EN Str D LED AM . LE ahl g Str . D geo ahl Kla aus ffn ung sse set et. , zen 3b .

(p.15) The viewfield is invisible, vignetted, or uneven in brightness. A device, lens, lamp, or filter is not attached correctly. Attach the devices to the correct positions. (p.12 to 15) A filter or a slider is located in an intermediate position. Move the filter slider to a click-stop position. Soil or dust is seen in the viewfield. Soil or dust exists on the lens, filter, or specimen. Clean the lens, filter, or specimen. (p.34) A motorized device does not work. The motorized device is not connected correctly. Connect the motorized device properly. (p.11 to 20) Sometimes the nosepiece does not rotate. A limitation is applied to the rotation of the nosepiece. Clear the limitation. (Refer to “ECLIPSE LV Series Support Tools Software manual” in the provided CD-ROM.) Unable to operate using the controller correctly. The setup work is not completed. Perform the setup works and specify the settings properly. (Refer to “ECLIPSE LV Series Support Tools Software manual” in the provided CD-ROM.) The device is not connected correctly. 32 Connect the device properly. (p.11 to 20) Care and Maintenance Nikon recommends daily care and maintenance for maintaining the performance as long as possible. Do not let dust, fingerprint, etc. get on the lenses. Soil on the lens or filter adversely affects the optical performance of the microscope. If lenses are contaminated, clean them according to the procedure described in “1. Cleaning Lenses and Filters.” When cleaning, be sure to turn off the power switch of the microscope (press the “ ” side) to avoid malfunction. Daily care and maintenance Clean the parts frequently manipulated by hands, such as eyepieces and glass plate, according to the procedure described in “1. Cleaning Lenses and Filters” without removing them from the microscope. Nikon recommends cleaning them frequently. Clean the tip of the objectives and filters to maintain the optical performance. When cleaning the objectives, remove them from the microscope. Clean them whenever they are contaminated. Microscopes and stages are contaminated with use. When you find the microscope is contaminated, clean them according to the description in “2. Cleaning the Painted Parts, Plastic Parts, and Printed Parts.” Cleaning tool and supplies (consumables) • Cleaning tool Brush (with soft bristles) (Use a cleanroom wiper in a clean room.) • Cleaning supplies (consumables) Ethyl or methyl alcohol Lens tissue (Use a cleanroom wiper in a clean room.) 33 VIII. Care and Maintenance 1 Cleaning Lenses and Filters Do not let dust, fingerprint, and so on get on the lenses and filters. Soil on the lens or filter adversely affects the viewing of the image. If any of the lenses get dirty, clean them as described below. • Either brush away dust with a soft brush, or else gently wipe it off with a piece of gauze. • Only if there are fingerprints or grease, dampen a piece of soft, clean cotton cloth, lens tissue, or gauze lightly with absolute alcohol (ethyl or methyl) and gently wipe off the soil. • Absolute alcohol is highly flammable. Be careful when handling it, when around open flames, when turning the power switch on/off, and so on. • Follow the instructions provided by the manufacturer when using absolute alcohol. 2 Cleaning the Painted Parts, Plastic Parts, and Printed Parts Do not use organic solvents such as alcohol, ether, or paint thinner on painted components and plastic components. Doing so could result in discoloration or in peeling of the printed characters. For persistent soil, dampen a piece of gauze with neutral detergent and wipe lightly. 3 Storage • • • • 4 Store the product in a dry place where mold is not likely to form. Store the objectives and eyepieces in a desiccator or similar container with a drying agent. Put a vinyl cover over the product to protect it from dust. Before putting on the vinyl cover, turn off the power switch of the microscope system (press the “ ” side) and wait until the lamp house gets cool sufficiently. Regular Inspections Periodical inspections of the product are recommended in order to maintain peak performance.
