  • Page 4: Before Use

    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.

  • Page 5: Storage

    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.

  • Page 6: Maintenance And Cleaning

    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. When glass components become dirty, the best way to clean them is to wipe them gently with a lint-free cloth.

  • Page 12: Assembly

    4 Assembly 4.1 Microscope head Inside the packaging the microscope head is already mounted but inclined towards the rear. In order to turn it to the front you must loosen the fixing screw on the tube connection point and after the turning fix it again with the screw. In case of removing the head completely from the housing, you should always make sure that you do not touch the lenses with your bare fingers and that no dust enters the apertures.

  • Page 13: Operation

    5 Operation 5.1 Getting started The very first step is to establish a power connection using the mains plug. After switching on the lighting you should first adjust the dimmer to a low level, so that when you look through the eyepiece for the first time, your eyes are not immediately subject to a high level of light.

  • Page 14: Pre-) Focussing

    5.2 (Pre-) focussing When you are observing an object, you must have the correct distance to the objective to achieve a sharp image. In order to find this distance at the beginning (without other default settings of the microscope) place the objective with the lowest magnification in the beam path, look through the right eyepiece with the right eye and turn it slowly using the coarse adjustment knob (see illustration).

  • Page 15: Adjusting The Interpupillary Distance

    5.3 Adjusting the interpupillary distance (For binocular and trinocular devices) With binocular viewing, the interpupillary distance must be adjusted accurately for each user, in order to achieve a clear image of the object. While you are looking through the eyepieces, use your hands to hold the righthand and lefthand tube housing firmly.

  • Page 16: Adjusting The Magnification

    5.5 Adjusting the magnification After prefocussing has been carried out using the objective with the lowest magnification (see section 5.2), you can then adjust the overall magnification using the nosepiece, as necessary. By turning the nosepiece you can bring any one of the four other objectives into the beam path.

  • Page 17: Adjusting The Illumination

    5.6 Adjusting the illumination To make sure that perfect image results are achieved during microscopic observation, it is important that the direction of light of the microscope is optimised. The necessary control elements for this are the height-adjustable condenser with aperture diaphragm.

  • Page 18: Using Rechargeable Batteries

    5.7 Using rechargeable batteries For OBE 103, OBE 109, OBE 113 There are three models of the series OBE-1, which enable a wireless usage. Therefore three rechargeable batteries are integrated in the power supply of these microscopes. Specification of the batteries: Battery type: LR6 (AA) Capacity:...

  • Page 19: Using Eye Cups

    5.8 Using eye cups The eye cups supplied with the microscope can basically be used at all times, as they screen out intrusive light, which is reflected from light sources from the environment onto the eyepiece, and the result is better image quality. But primarily, if eyepieces with a high eye point (particularly suitable for those who wear glasses) are used, then it may also be useful for users who don’t wear glasses, to fit the eye cups to the eyepieces.

  • Page 20: Using Oil Immersion Objectives

    5.9 Using oil immersion objectives The 100x objectives of the OBE-1 series are objectives which can be used with oil immersion (they are always marked with the word “OIL”). Using these generates a particularly high resolution for microscopic images. To use oil immersion correctly, please follow these steps. 1.

  • Page 21: Changing The Bulb

    6 Changing the bulb Before changing the bulb the device must be switched off and unplugged. To change the bulb, tip the device carefully to the back or side. When doing this, please make sure that all microscope components are firmly fixed. The bulb holder is on the underside of the device.

  • Page 22: Using Optional Accessories

    8 Using optional accessories 8.1 Polarisation unit The polarisation unit consists of a polariser and an analyser. Both consist of a round glass plate with an external holder ring. To mount the analyser you have to remove the microscope head at first. Then the analyser has to be inserted into the round aperture of the beam path right above the nose piece.

  • Page 23: Camera Connection

    8.3 Camera connection OBE 104, OBE 110, OBE 114 Due to the trinocular tube, which is a standard fitting for the models OBE 110 and OBE 114, it is possible to connect microscope cameras to the device, in order to digitally record images or sequences of images of an object being observed.

  • Page 26: Service

    10 Service If, after studying the user manual, you still have questions about commissioning or using the microscope, or if unforeseen problems should arise, please get in touch with your dealer. The device may only be opened by trained service engineers who have been authorised by KERN.
