Page 4: Before Use
1 Before use 1.1 General notes You must open the packaging carefully, to make sure that none of the accessories in the packaging fall on the floor and get broken. In general, microscopes should always be handled carefully because they are sensitive precision instruments. -
Page 5: Storage
1.3 Storage You should ensure that the device is not exposed to direct sunlight, temperatures which are too high or too low, vibrations, dust or a high level of humidity. The ideal temperature range is between 0 and 40°C and a relative humidity of 85% should not be exceeded. -

Page 9: Assembly
4 Assembly The first step is to position the microscope stand on a firm, level surface. The holder is already on pillar of the stand, but you must always check whether it is fixed securely and that it is in the correct position (preferably centrally and facing to the front). - Page 10 Assembled stereo zoom microscope OZL-44-BA-e-1510...

Page 11: Operation And Functionality
Please see section 5.7 for more details on adjusting the lighting. If the device has a camera connection (OZL 441), then for binocular use, you must let the trinocular toggle rod on the left side of the microscope head stay slid-in. -
Page 12: Dioptre Adjustment And Focussing
5.4 Dioptre adjustment and focussing A special feature of stereo microscopes is that they are fitted with an optical unit which has a relatively high depth of field. In order to be able get the most benefit from this feature, each user must synchronise the focussing mechanisms for themselves. The steps to do this are described in the following section. -
Page 13: Adjusting The Stand
5.5 Adjusting the stand Torque of the focus wheels You can adjust the torque of the focus wheels by turning the ring which is fitted along the axis of the lefthand focus wheel. To do this you need a special wrench which is included with delivery. The ring has holes which the wrench can hook into, so that you can then turn it in the desired direction. -
Page 14: Using Eye Cups / High Eye Point Eyepieces
5.6 Using eye cups / High Eye Point eyepieces The eye cups supplied with the microscope can basically be used at all times, as they screen out intrusive light, which is reflected from light sources from the environment onto the eyepiece, and the result is better image quality. But primarily, if eyepieces with a high eye point (particularly suitable for those who wear glasses) are used, then it may also be useful for users who don’t wear glasses, to fit the eye cups to the eyepieces. -
Page 15: Lighting Control
5.7 Lighting control The microscopes in the OZL-44 series have an adjustable reflected and transmitted light illumination. The power supply is guaranteed by connecting the mains cable and pressing the main switch on the right, rear corner. The control wheel on the righthand side surface of the stand base is responsible both for on-/off-switching and the adjustment of the light intensity of the transmitted illumination. -
Page 16: Fitting And Adjusting A Camera
5.9 Fitting and adjusting a camera (OZL 441) You can connect special microscope cameras to trinocular devices in the OZL-44 series, so that you can digitally record images or sequences of objects being observed. The connection for this is on the top side of the microscope head. -
Page 17: Changing The Bulb
5.10 Changing the bulb The devices in the OZL-44 range with lighting are all fitted with LED bulbs. Due to the long service life of an LED lighting system, for these microscopes it will not be necessary to simply change a bulb. Problems with the lighting unit would therefore, in most cases, be caused by defects in the electrical system. -
