1. Safety notes

• For power supply use only electrical sockets

with ground contact.

2. Description, technical data

The monocular course microscope allows twodimensional viewing of objects (thin sections of plant or animal specimen) in 40x to 1000x magnification.

The microscope 1013366 is for operation with a mains voltage of 115 V (±10%), and the 1013127 unit is for operation with 230 V (±10%).

Stand: Robust, all metal stand with arm permanently connect to the base. Focussing by means of separate knobs for coarse and fine adjustment located on either side of the stand and operated by rack and pinion drive with ball bearings, adjustable stopper for protecting the object

slides and objective

Tube: Monocular inclined 45°, head rotation 360° Eyepiece: Widefield eyepiece WF 10x 18 mm Objectives: Revolver with 4 DIN achromatic

objectives 4x / 0.10, 10x / 0.25, 40x / 0.65, 100x / 1.25 oil (with specimen protection)

Magnification: 40x, 100x, 400x, 1000x Object stage: x-y cross table, 125 x 130 mm

with object guide and coaxial adjustment knobs perpendicular to the object stage, adjustment range 70 x 30 mm

Illumination: Adjustable LED lighting integrated in base

Power supply: Via plug-in power supply 6 V DC, 200 mA

Mains connection: 1013366: 115 V, 50/60 Hz; 1013127: 230 V, 50/60 Hz

Condenser: Abbe condenser N.A.1.25 NA 0.65 with iris diaphragm , filter holder and blue filter,

focussed via rack and pinion drive

Dimensions: 220 x 154 x 359 mm³ approx. Weight: 4.5 kg approx.

3. Unpacking and assembly

The microscope is packed in a molded styrofoam container.

• Take the container out of the carton remove

the tape and carefully lift the top half off the container. Be careful not to let the optical items (objectives and eyepieces) drop down.

• To avoid condensation on the optical compo-

nents, leave the microscope in the original packing to allow it to adjust to room temperature.

• Using both hands (one around the pillar and

one around the base), lift the microscope from the container and put it on a stable desk.

• The objectives will be found within individual

protective vials. Install the objectives into the microscope nosepiece from the lowest magnification to the highest, in a clockwise direction from the rear.

• Put the head onto the top of the stand and

tighten the head-lock-screw. Insert the eyepiece into the tube.

4. Operation

• Set the microscope on a level table.

• Place the object to be observed in the center

of the object plate. Use the clips to fasten it into place. Make certain that the specimen is centered over the opening in the stage.

• Connect the mains cable to the net and turn

on the switch to get the object illuminated.

• Make certain that the specimen is centered

over the opening in the stage.

• To obtain a high contrast, adjust the back-

ground illumination by means of the iris diaphragm and the variable illumination control.

• Rotate the nosepiece until the objective with

the lowest magnification is pointed at the specimen. There is a definite “click” when each objective is lined up properly.

NOTE: It is best to begin with the lowest power objective. This is important to reveal general structural details with the largest field of view first. Than you may increase the magnification as needed to reveal small details. To determine the magnification at which you are viewing a specimen, multiply the power of the eyepiece by the power of the objective.

• Adjust the coarse-focusing-knob which

moves the stage up until the specimen is focused. Be careful that the objective does not make contact with the slide at any time. This may cause damage to the objective and/or crack your slide.

• Adjust the fine-focusing-knob to get the im-

age more sharp and more clear.

• Colour filters may be inserted into the filter

holder for definition of specimen parts. Swing the filter holder out and insert colour filters.

• Use the knobs of the mechanical stage to

move the slide side-, back- and forwards. The vernier provides acc urate loc ation of the specimen area.

• Always turn off the light immediately after

use.

• Be careful not to spill any liquids on the mi-

croscope.

• Do not mishandle or impose unnecessary

force on the microscope.

• Do not wipe the optics with your hands.

• Do not attempt to service the microscope

yourself.

5. Storage, cleaning, disposal

• Keep the microscope in a clean, dry and

dust free place.

• When not in use always cover the micro-

scope with the dust cover.

• Do not expose it to temperatures below 0°C

and above 40°C and a max. relative humidity of over 85%.

• Always unplug the mains plug before clean-

ing or maintenance.

• Do not clean the unit with volatile solvents or

abrasive cleaners.

• Do not disassemble objective or eyepieces

to attempt to clean them.

• Use a soft linen cloth and some ethanol to

clean the microscope.

• Use a soft lens tissue to clean the optics.

• The packaging should be disposed of at

local recycling points.

• Should you need to

dispose of the equipment itself, never throw it away in normal domestic waste. Local regulations for the disposal of electrical equipment will apply.
