Page 11: Before Use
Before use General information The packaging must be opened carefully to prevent the 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 transportation is therefore particularly important, especially to avoid endangering the optical components. -
Page 12: Basic Information (General)
Basic information (general) General information on warnings Warnings are used in these operating instructions to warn you of possible personal injury or damage to property in certain situations. Signal word Description DANGER Failure to observe the instructions will lead directly to serious injury, permanent impairment (e.g. -
Page 13: Intended Use
Indicates a prescribed action Intended use The OBE-12 and OBE-13 are versatile and are mainly used for the analysis of translucent and thin, high-contrast, less demanding specimens (e.g. plant tissue, stained cells and parasites). Improper use Do not use the device in potentially explosive atmospheres or for measurements in liquids or on live parts. -
Page 14: Basic Warnings And Safety Instructions
Basic warnings and safety instructions Observe the notes in the operating instructions Read the operating instructions carefully before commissioning/using the device, even if you already have experience with KERN devices. Always keep the instructions in the immediate vicinity of the appliance. Staff training The appliance may only be used by persons who have read and understood the operating instructions, in particular the chapter on safety. - Page 15 ⚠ WARNING Risk of injury due to electric shock! ● Risk of short circuit due to penetration of liquids into the housing! ● Do not immerse the appliance or accessories in water. Make sure that no water or other liquids get into the housing. ●...
- Page 16 CAUTION Keep a sufficient distance from heat sources. Do not use the device in environments with high humidity or water mist NOTE ● To avoid damaging the device, do not expose it to extreme temperatures, extreme humidity or moisture. ● Do not use harsh cleaners, abrasive cleaners or solvents to clean the appliance. 14 | en OBE-12_13-BA-e-2411.docx...

Page 17: Transportation And Storage
Transportation and storage Note If you store or transport the device improperly, the device may be damaged. Observe the information on transporting and storing the appliance. Transportation We recommend using the original packaging for shipping, transportation or storage of the microscope components. To prevent damage from shocks, all moving parts that can be assembled and disassembled must be packed separately. -
Page 18: Unpacking And Commissioning
Unpacking and commissioning Unpacking In the event of a return, please observe the instructions in the chapter "Packaging/return transportation On receipt of the device, you should first check that no damage has occurred during transportation, that the outer packaging, the housing, other parts or even the device itself have not been damaged. -
Page 19: Assembly
Assembly Microscope head The microscope head is firmly attached to the rest of the microscope and therefore cannot be removed or rotated. The tube, however, can be rotated 360° thanks to the butterfly design, which allows flexible adjustment of the eyepieces. Objectives Depending on the model, all three or four lenses are already screwed onto the nosepiece. -
Page 20: Operation
Operation 10.1 First steps The first thing to do is to connect the power supply using the mains plug. The light intensity control (dimmer) should first be set to a low level so that the eyes are not immediately exposed to too much light when looking into the eyepieces for the first time. -
Page 21: Pre-) Focusing
10.2 (Pre-) focusing 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 22: Adjusting The Interpupillary Distance
10.3 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 23: Adjusting The Magnification
10.5 Adjusting the magnification After pre-focusing has been carried out using the lens with the lowest magnification (see 10.210.2),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 24: Setting The Lighting
In order to obtain perfect image results during microscopic observation, it is important that the microscope's light guidance is optimized. The control element that plays the most important role in the OBE-12 and OBE-13 series is the height-adjustable condenser with aperture diaphragm. -
Page 25: Using The Eyecups
10.7 Using the eyecups 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 a 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 26: Use Of Oil Immersion Lenses
10.8 Use of oil immersion lenses The 100x objectives of the OBE-13 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. -
Page 27: Changing The Bulb
Changing the bulb The appliances in the OBE-12 and OBE-13 series with lighting are all equipped with LED lamps. Due to the long service life of LED lighting, regular lamp replacement will not be necessary with this microscope. In most cases, problems with the lighting would therefore be caused by defects in the electrical system. -
Page 28: Use Of Optional Accessories
Use of optional accessories 12.1 Dark field unit The following option is available for realizing dark field applications. A dark field insert with an integrated black disk can be screwed into the standard condenser of the microscope from below (see illustration on the right). -
