Parts overview and scope of delivery

Scope of delivery: Microscope with integrated mains power cable and plug (A), objective (fixed) (B), 2 pcs. WF 10x eye-pieces (C), white object plate (translucent) (D)

Choice of location

Choose a suitable location before installation and commissioning. Place the device on a stable, level, and vibration-free surface.

Attaching and moving the microscope head

1. Insert the microscope head with the objective first into the holder from above.
2. Hand-tighten the fixing screw on the holder to fix the microscope head.
3. Loosen the fixing screw on the microscope head to rotate the part above the objective to the de-sired observation position.
4. Hand-tighten the fixing screw on the microscope head to lock the head in position.

Inserting the object plate

1. Swing the holding clamps to the sides.
2. Place the object plate on the support.

Setting up power supply

1. Insert the plug of the main power cable into the wall socket.
2. Insert the DC hollow plug of the incident light power cable into the DC connection socket above the vertical pillar.

Turning on/off the device

1. Move On/Off switch to position ‘I’ to turn on the device.
2.  Move On/Off switch to ‘O’ position to turn off the device.

Adjusting the illumination

This device provides illumination with a permanently installed LED light source. To control the brightness proceed as follows:

1. Turn on the device.
2. Turn/Move the dimmer control to adjust the brightness of the light source.
3. Place the object on the object plate.
4.  Switch on incident light illumination.
5. Move the lamp holder to the desired position.

Observation setting

Illustration 2: Binocular head with diopter adjustment at the eyepiece This microscope is equipped with a binocular head. The interpupillary distance and the diopter settings can be adjusted individually.

1.  With the eyes look through both eyepieces.
2. Change the distance between the eyepieces by pushing them together or pulling them apart until a circular image of the observed object is visible.
3. Turn the diopter adjustment ring to position ‘0’.
4. Turn the zoom button to position ‘5’.
5. With the left eye, look through the left eyepiece and turn the focusing wheel until a sharp image of the observed object is visible.
6.  With the right eye, look through the right eyepiece and turn the diopter adjustment ring until a sharp image of the observed object is visible too. The diopter adjustment can also be done in the opposite way on the left eyepiece.

Friction setting

If the friction setting is too smooth, the microscope head will move downwards by itself because the weight is completely pushing on the guide rail. This creates a blurred image.
To avoid this, tighten the friction adjustment wheel slightly.

Using the trinocular extension

Illustration 3: Trinocular extension Depending on the adapter* attached, a SLR camera, a system camera or a C-mount camera can be attached to the trinocular extension.

NOTICE! Cameras usually show a smaller field of view than eyepieces. This is in part due to the sensor size and cannot be changed.

To attach a suitable camera adapter, proceed as follows:

1. Loosen the fixing screw on the extension and remove the dust cover.
2. Push in the slider for the trinocular extension to release the function.
3. Insert/attach the desired camera adapter.
4. Tighten the fixing screw again.
5. Use the focus of the camera adapter to adjust the camera focus. Most camera models can thus be adjusted parfocal to the eyepieces.

NOTICE! Information on suitable accessories can be found in the chapter “Optional accessories”. *not included in the scope of delivery / optionally available

Attaching optional accessories to the objective tube

The objective tube is equipped with an M48 x 0.75 thread for mounting ancillary lenses. The outer notch on the lens ring is used to attach a ring illuminator. *not included NOTICE! Information on suitable accessories can be found in the chapter “Optional accessories”.

Cleaning and maintenance

• Protect the device from dust and moisture!

• Avoid fingerprints and similar contamination of the optical surfaces.

• The residual moisture must be completely degraded before use.

• Disconnect the power supply by pulling the mains plug when the appliance is not in use, in case of a longer interruption of operation, and before any maintenance and cleaning work.

• Only clean the device externally using a dry cloth. Do not use a cleaning solution to prevent damage to the electronic parts.

• Do not use organic solvents (e.g. alcohol, ether, acetone, xylol or other dilutions) to clean lacquered parts or plastic parts!

• Disassemble optical elements (e.g. objective, eyepiece, etc) before cleaning.

• Blow away loose dust from the lens surfaces first.

• Use high-quality lens cleaning towels or soft cloth and moisten it with a little bit of pure alcohol
  (available in a drug store). Wipe the lens surface with it.

• Pull a dust protection cover* over the microscope and store it in a closed container in a dry and mold-free place. Store the microscope and the accessories in the relevant containers when they are not used for a longer time. It is recommended to store also objectives and eyepieces in closed containers with desiccant.

(*depending on the model a dust protection cover and box can be part of the content)

NOTICE Remember: A well-maintained microscope will keep its optical quality for years and thus maintain its value.
