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. When using or transporting the microscope it is

particularly important to avoid abrupt movements, as this may damage the optical

components.

You should also avoid getting dirt or finger prints on the lens surface, because in

most cases this will reduce image clarity.

To maintain the performance of the microscope, it must never be disassembled. So

components such as lenses and other optical elements should be left as they were

before use. Also the electrical parts of the device must not be tampered with, as in

this area there is an additional risk of triggering an electric shock.

1.2 Notes on the electrical system

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 each 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 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.

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.

The device should always be located on a rigid, smooth, horizontal surface.

For devices with pillar stands, the microscope holder must not be rotated back too

far. If you do this, there is a risk that the microscope could tip over.

When the microscope is not being used, you should fit the objective cap and cover

the microscope with the enclosed dust protective cover.

If the eyepieces are being stored separately, the protective caps must be fitted to the

tube connectors. 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.

1.4 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 (if lighting unit is fitted).

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 microscope should give many

years of efficient service.

Should repairs still be necessary, please contact your KERN dealer or our Technical

Department.

4 Assembly

The assembly of the microscope stand together with the holder has to be carried out

as follows:

1. Microscope stand base

a. Stand plate:

Attach the stand pillar with help of the screw onto the stand plate.

Afterwards place the plate on an even and stable table surface.

2. Microscope arm

Attach the arm to the pillar with help of the joint, which is already fitted to the

arm. Fasten the appropriate screws for arm, joint and carrier ring.

3. Connecting joint arm –holder

On the appropriate microscope arm end there is the connection point for the

microscope holder. This point is blocked. Thus the both Allen screws need to

be loosened in order to attach the holder.

Subsequently attach the microscope holder connecting piece, which is already

mounted to the holder by a joint, to the connection point and retighten the both

screws.

4. Microscope holder

Fix the holder in a preferred position by using the clamp lever on the joint

connection.

Please see section 5.5 for more details on adjusting the stand.

The next step is to place the microscope head on the holder, by passing the

objective through the holder ring until the rest of the head is above the ring.

You must use the small silver adjusting screw on the front of the holder ring to fix the

head in place.

The alignment of the microscope head is left to the user to do and can be adjusted to

suit the individual application situations.

Then you can remove the protective caps from the tube connectors so that you can

then fit the eyepieces. When doing this, please be particularly careful that you do

not touch the optical lenses with your fingers and that no dust enters the

apertures.

You should also never fit two eyepieces with different magnifications.
