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.

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. OZL-46-BA-e-2012...
Special cleaner for optical lenses Special optical cleaning cloths Bellows Brush When handled correctly and checked regularly, the microscope should give many years of efficient service. Should repairs still be necessary, please contact your KERN dealer or our Technical Department. OZL-46-BA-e-2012...
You can fit a C-mount adapter to the appropriate connection point on the top of the microscope head for trinocular devices (OZL 464, OZL 466, OZL 468). This enables you to fit and use digital cameras (see section 5.9). OZL-46-BA-e-2012...
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 OZL-46 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. OZL-46-BA-e-2012...
The way to fix the position is to use an adjusting screw, which is located directly on the back of the holder. For devices with mechanical stand (OZL 467, OZL 468) this function is not available. Only with help of the focus wheels you can adjust the height setting of the microscope head. OZL-46-BA-e-2012...
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) OZL-46-BA-e-2012...
The lighting units which are suitable for devices of the OZL-46 series, are goose neck lighting units (see figure). These are available as LED as well as halogen versions and also have an on/off switch or different controller.
5.9 Fitting and adjusting a camera (OZL 464, OZL 466, OZL 468) You can connect special microscope cameras to trinocular devices in the OZL-46 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.
5.11 Changing the bulb The devices in the OZL-46 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.
The torque of the focus wheels is set too high The microscope head slips down The torque of the focus wheels is set too low while you are viewing the object Eyes get tired easily The dioptre adjustment is not correct The brightness adjustment is not correct OZL-46-BA-e-2012...
The device may only be opened by trained service engineers who have been authorised by KERN. 10 Disposal The packaging is made of environmentally-friendly materials, which you can dispose of at your local recycling centre.
