Page 4: Before Use
If you are using an extension cable, then the mains cable you use must be earthed. When carrying out any procedures whereby you come into contact with the electrical system of the device, such as, for example, changing the bulb or fuse, only carry out these procedures when the power is disconnected.

Page 5: Storage
In most cases, if dust and dirt gets inside the optical unit of a microscope this can cause irreversible errors or damage. The best way to store accessories which consist of optical elements, such as, for example, eyepieces and objectives, is in a dry box with desiccant. OZM-98-BA-e-1610... -

Page 16: Operation And Functionality
As soon as the lefthand and righthand visual fields exactly overlap each other, this is the correct interpupillary distance. 5.3 Adjusting the magnification As the KERN OZM-9 series are stereo zoom microscopes, then you adjust the magnification using the two zoom adjustment wheels on the lefthand and righthand side of the microscope head. -

11. Then look through the left eyepiece with the left eye and use the lefthand dioptre adjustment ring to also adjust the optimum focus of the object. 12. In this way, the object being observed will be in focus at any zoom setting. OZM-98-BA-e-1610... -
Page 18: Adjusting The Stand
The pneumatic spring ensures the height adjustment of the upper part of the microscope stand. For varying the spring force, the adjustment screw on the middle joint of the stand must be used. Before performing this, the upper part needs to be kept in a completely depressed position (see lower picture). OZM-98-BA-e-1610... -
Page 19: Using Eye Cups / High Eye Point Eyepieces
In order to maintain hygiene, we would therefore recommend that you clean the eye cups regularly (e.g. with a damp cloth). Eye cups High Eye Point eyepiece (identified by the glasses symbol) OZM-98-BA-e-1610... -
Page 20: Brightness Adjustment
5.7 Brightness adjustment There is only the usage of incident illumination available when working with KERN stereo microscope sets. Therefor a LED ring light (see picture below) is required, that can be mounted to the bottom of the microscope head (see chapter 4 Assembly). -
Page 21: Fitting And Adjusting A Camera
This means that when the device is used in trinocular mode, you will see one image in the left eyepiece and one on the reflex camera or monitor of the microscope camera. This means that the 3D effect is lost. OZM-98-BA-e-1610... - Page 22 (0,3x, 0,5x) are used. In order to be able to bring both images into focus, the focus can be adjusted by those adapters.

Page 23: Using Additional Accessories
You can fit these objectives by simply screwing them onto the bottom side of the microscope head. When you are doing this, you must avoid touching the objective lenses with your fingers or leaving any dust between the standard objective and the auxiliary objective. OZM-98-BA-e-1610... -
