Operating Instructions

Dampen the cleaning cloth with a spectacle cleaning fl uid and use it on very dirty lenses. Protect the device from dust and moisture. Batteries should be removed from the device if it is not going to be used for a long period of time. DISPOSAL Dispose of the packaging material/s as legally required. Consult the local au- thority on the matter if necessary. Do not dispose of electrical equipment in your ordinary refuse. The European guideline 2002/96/EU on Electronic and Electrical Equipment Waste and relevant laws applying to it require such used equipment to be separately collected and recycled in an environment-friendly manner. Empty batteries and accumulators must be disposed of sepa- rately. Information on disposing of all such equipment made after 01 June 2006 can be obtained from your local authority. In accordance with the regulations con- cerning batteries and rechargeable bat- teries, disposing of them in the normal household waste is explicitly forbidden. Ple- ase make sure to dispose of your used batte- ries as required by law — at a local collection point or in the retail market. Disposal in dome- stic waste violates the Battery Directive. Batteries that contain toxins are marked with a sign and a chemical symbol. „Cd“ = cadmi- um, „Hg“ = mercury, „Pb“ = lead.

Before you assemble your microscope, make sure that the table, desk or whatever surface that you want to place it on is stable, and does not wobble. Electric LED illumination? The microscope is equipped with modern LED lighting (a light-emitting diode) that illuminates the specimen from below. (By the way, the thing you want to observe with the microscope is known as the object or specimen.) How do I adjust my microscope correctly? First, loosen the screw (Fig. 1, 7) and turn the microscope head (Fig. 1, 6) into a comfortable viewing position. Each observation starts with the lowest magnifi cation. Adjust the microscope stage (Fig. 1, 11) so that it goes all the way down to the lowest position. Then, turn the objective nosepiece (Fig. 1, 8) until it clicks into place at the lowest magnifi cation (objective 4x). Note: Before you change the objective setting, always move the microscope stage (Fig. 1,

11) to its lowest position. This way, you can

avoid causing any damage! Now, insert the 10x eyepiece (Fig. 1, 1) into the Barlow lens (Fig. 1, 3). Make sure that the Barlow lens is placed all the way into the eyepiece supports (Fig. 1, 5) and is not pulled out (Fig. 2). How do I observe the specimen? After you have assembled the microscope with the adequate illumination and adjusted it correctly, the following basic rules are to be observed: Start with a simple observation at the lowest magnifi cation. This way, it is easier to position the object in the middle (centering) and make the image sharp (focusing). The higher the magnifi cation, the more light you will require for a good image quality. Abb. 2

Now place the prepared specimen (Fig. 1, 19) directly under the objective on the microscope stage (Fig. 3). The object should be located directly over the illumination (Fig. 1, 12). In the next step, take a look through the eyepiece (Fig. 1, 1) and carefully turn the focus knob (Fig. 1, 16) until the image appears clear and sharp. Now you can select a higher magnifi cation by slowly removing the Barlow lens (Fig. 1, 3) from the eyepiece support (Fig. 1, 5). When the Barlow lens is almost completely pulled out, the magnifi cation can be increased to –almost double. If you would like an even higher level of magnifi cation, insert the 16x eyepiece (Fig. 1, 2) and turn the objective nosepiece (Fig. 1, 8) to a higher setting (10x or 40x). Important tip: The highest magnifi cation is not always the best for every specimen! Note: Each time the magnifi cation changes (eyepiece or objective change, pulling out the Barlow lens), the image sharpness must be readjusted with the focus knob (Fig. 1, 16). When doing this, make sure to be careful. If you move the microscope stage too quickly, the objective and the slide could come into contact and become damaged! For transparent objections (e.g. protozoa), on the other hand, the light shines from below, through the opening in the microscope stage and then through the object. The light travels further through the objective and eyepiece, where it is also magnifi ed, and fi nally goes into the eye. This is transmitted- light microscopy. Many microorganisms in water, many plan components and the smallest animal parts are already transparent in nature. Others have to be prepared. We may make them transparent through a treatment or penetration with the right materials (media), or by taking the thinnest slices from them (using our hand or a specimen slicer), and then examine them. You can read more about this in the following sections. How do I make thin specimen slices? Only do this with the supervision of your parents or another adult. As I already pointed out, the thinnest slices possible are taken from an object. In order to get the best results, we need some wax or paraffi n. It is best if you get a candle. Place the wax in a pot and heat it carefully over a low burner. Now, dip the object in the liquid wax a few times. Then, let the wax get hard. Using the specimen slicer (Fig. 1,19) or a knife/scalpel, cut the smallest slices from the object that is covered with wax. These slices are to be laid on a slide and covered with a cover slip. How do I make my own specimens? Take the object that you want to observe and place it on a glass slide. Then, add a few drops of distilled water on the object (Fig.

7) using a pipette (Fig. 1, 19). Now, place a

cover slip vertically at the edge of the drop of water, so that the water runs along the edge of the cover slip. Then, slowly lower the cover slip over the water drops (Fig. 8). Note: The included glue “gum media” (Fig. 1,

18) is used to make permanent prepared

specimens. Use this in place of the distilled water. If you want to keep the object in place on the slide permanently, use the gum media.

Abb. 3 Abb. 7 Abb. 816 How do I install the MicrOcular? Note: The MicrOcular only works with the included Barlow lens! The magnifi cation setting is changed when the MicrOcular is used, and it must be readjusted with the focus knob. First, remove the Barlow lens (Fig. 4, 3) with the current eyepiece from the eyepiece support (Fig. 4) and place the MicrOcular (Fig. 5, 4) in the eyepiece (Fig. 5). How do I install the software? 1 Insert the CD-ROM supplied in your CD or DVD drive. The installation menu opens automatically. If it doesn‘t, please switch to Windows Explorer and select your CD drive. Start the fi le “setup.exe“ by double- clicking it.

2. A choice of languages is shown. Choose

your preference. Confi rm it by clicking „OK“. At the „Welcome“ screen, click „Next“>“.

3. In the next screen you will be asked for the

„Destination Folder“. Confi rm your input with „Next>“.

4. The setup status screen shows. This

advises current operation status with a progress bar. This may take a few minutes.

5. The „Completed the Photomizer Setup

Wizard“ screen shows. Click here on „Finish“. MikrOkular driver installation During Photomizer SE software installation the correct driver for your operating system will be installed automatically. No manual input is needed. In rare cases the device may not be recognised by your computer. As a rule you need then only install the driver manually from the CD. If this fails please refer to the troubleshooting chapter that follows. Troubleshooting: the device isn‘t recognised by the computer (USB)

1. This occurs in rare cases whith some OEM

Windows Vista or XP versions. The device is not defective. Updating the notebook or PC USB driver usually suffi ces.

2. If not, proceed as below. (The maker

cannot accept any liability whatsoever in these cases

Delete ghost devices. These are devices not actually currently connected to your computer. The reason for this is that Windows generates a system settings entry for each USB device ( e.g USB Stick) on each port. It then seeks that/those device/s each time it‘s started. This slows down USB device recognition and Windows booting and causes non-recognition of USB ports. Cleaning up the system environment and deleting devices that are no longer in use helps here. To do so right click WORKPLACE (COMPUTER in Vista) and open the PROPERTIES menu. Then click the ADVANCED tab (ADVANCED SYSTEM SETTINGS in Vista) and then ENVIRONMENT VARIABLES. Choose the NEW option in ENVIRONMENT VARIABLES. Enter the following under VARIABLE NAME. devmgr_show_nonpresent_devices Under VARIABLE VALUE enter „1“. Confi rm your input with OK and then reboot the computer. Change to the device manager. In the VIEW menu activate the SHOW DEVICES OPTION. The ghost devices previously not shown will now be displayed in light grey. Check the various categories including USB, memory size, etc. Only delete entries for devices you no longer use.

If you need further assistance please visit the maker‘s home page at www.photomize Make sure your microscope has a long service life. Clean the lens (objective and eyepiece) only with the cloth supplied or some other soft lint- free cloth (e.g.microfi bre). Do not press hard as this might scratch the lens. Ask your parents to help if your microscope is really very dirty. The cleaning cloth should be moistened with cleaning fl uid and the lens wiped clean using little pressure. Make sure your microscope is always protec- ted against dust and dirt. After use leave it in a warm room to dry off. Then install the dust caps and keep it in the case provided.18 Troubleshooting Error Solution No recognizable image
