5 Operation and functionality

After assembly, if the microscope is ready for use, then you must first establish a

power connection using the cable supplied.

Please see section 5.7 for more details on adjusting the lighting.

Do not forget to remove the cap from the bottom of the objective, so that you will then

be able to see a reflection of the object being observed in the eyepiece.

All important functions which relate to the use of the devices in this document are

described in the following sections.

Different users have different interpupillary distances. So each time a different

person uses the microscope, the gap between the two eyepieces must be re-

adjusted.

While you are looking through the eyepieces, use one hand to hold the righthand or

lefthand prism housing firmly.

By rotating outwards or inwards, you can either increase or reduce the interpupillary

distance.

As soon as the lefthand and righthand visual fields exactly overlap each other, this is

the correct interpupillary distance.

As the KERN OSF-4 series covers stereo microscopes (without zoom), we will

describe how to set the magnification using the integrated and rotating objective.

For the devices in this series, you can select between two (OSF 430, OSF 431) or

three (OSF 434, OSF 435) different magnification factors at any time.

Chapter 6 "Optical data" gives information on the possible overall magnification which

the microscope can produce. It will also include the optional use of different

eyepieces.
