1 Before use
General notes
The packaging must be opened carefully to prevent any accessories inside from falling
to the floor and breaking.
In general, a microscope should always be handled with great care, as it is a sensitive
precision instrument. Avoiding abrupt movements during operation or transport is
therefore particularly important, especially to avoid endangering the optical components.
Similarly, you should avoid dirt or fingerprints on the lens surfaces, because in most
cases this reduces image clarity.
If the performance of the microscope is to be maintained, it must never be
disassembled. Components such as objective lenses and other optical components
should therefore be left as they are found at the beginning of operation.
Notes on the electrics
Before connecting to a mains power supply, you must make sure that you are using the
correct input voltage. The information to select the correct mains cable is located on the
device, on the rear of the product directly above the connection socket. You must comply
with this information. If you do not comply with these specifications, then fires or other
damage to the device could occur.
The main switch must also be switched off before the mains cable is connected. In this
way you will avoid triggering an electric shock.
If you are using an extension cable, then the mains cable you use must be grounded.
When carrying out any procedures whereby you come into contact with the electrical
system of the device, such as, for example, changing the LED lamp, only carry out
these procedures when the power is disconnected.

Storage
Avoid exposing the device to direct sunlight, high or low temperatures, shock, dust
and high humidity.
The suitable temperature range is 0 - 40° C and a relative humidity of 85% should not
be exceeded.
The device should always be on a firm, smooth and horizontal surface.
When the microscope is not in use, it is best to cover it with the dust cover provided.
Dust or dirt inside the optics of a microscope can cause irreversible malfunctions or
damage in many cases.
Accessories consisting of optical elements, such as additional objectives, are
preferably stored in a drying box with desiccant.

Maintenance and cleaning
In any event, the device must be kept clean and dusted regularly.
If any moisture should be occur, before you wipe down the device you must ensure that
the mains power is switched off.
When glass components become dirty, the best way to clean them is to wipe them
gently with a lint-free cloth.
To wipe oil stains or finger prints off the lens surface, moisten the lint free cloth with a
mixture of ether and alcohol (70 / 30 ratio) and use this to clean the lens.
You must be careful when handling ether and alcohol, as these are highly flammable
substances. You must therefore keep it away from naked flames and electrical devices
which can be switched on and off, and only use it in well-ventilated rooms.
However organic solutions of this type should not be used to clean other components of
the device. This could lead to damage to the paint finish. To do this, it is sufficient to use
a neutral cleaning product.
You could also use the following cleaning products to clean the optical components:
•Special cleaner for optical lenses
•Special optical cleaning cloths
•Bellows
•Brush
When handled correctly and checked regularly, the video microscope should give many
years of efficient service.
Should repairs still be necessary, please contact your KERN dealer or our Technical
Department.

4 Assembly
Assembling the microscope stand
Secure the microscope column with the plate and
the supplied M5 threaded screws (3x). Tighten
the screws on the underside of the plate using the
supplied M5 hexagonal tool.
View microscope stand
Set up the microscope stand after successful
assembly.
Assembling the microscope body
Then insert the microscope head (1) into the
shapes on the holder (2) of the microscope stand.

Secure microscope head
To secure the microscope head to the stand,
tighten the screws (2x) on the outside of the
housing using the Allen key provided.
Power connection
Plug the power cable into the connector on the
microscope.
Be careful not to twist or bend the power cable.
Only use the original adapter supplied.

5 Operation
If the microscope is ready for use after it has been assembled, then the power
connection must first be made using the power cord. Only insert the power plug into a
suitable socket. Make sure that the power cord is properly routed.
All important functions which are useful for the operation of the device are described in
the following sections.
The max/min parfocality is already optimally preset upon delivery.
5.1 Switching on the device
To switch on the microscope, press the On/Off
button (1) until it is backlighted blue. The LED
operating indicator (2) (PL) lights up green as
soon as the microscope is switched on. The
system now starts in the operating mode.

5.3 Adjusting the illumination
Turn the dimmer for lighting (4) on the right side
of the ring light to adjust the illumination

5.2 Switching the illumination on/off
The switch for the ring illumination is located on
the side of the ring light. To switch the illumination
on/off, operate the switch (3)

5.4 Adjusting the magnification and focus
Since the OIV series are zoom microscopes, the
zoom factor (0.7x-4.5x) can be changed using the
Zoom adjustment wheel (5). Turn the adjustment
wheel to the maximum magnification. Focus the
image using the focus wheel (6).
Repeat the process if necessary.
