Safety Precaution

1. Carefully open the box, avoid the accessories, like lens, dropping to ground and being damaged.

2. Check the input voltage, be sure the input voltage which signed on the microscope is consistent with the

power supply voltage, or it will bring a serious damage to the instrument.

3. Do keep the instrument out of direct sunlight, high temperature or humidity, dusty and easy shaking

environment. Make sure the stage is smooth, horizontal and firm enough.

4. To prevent the microscope body from turning over, its pivot angle must be limited to 30°.

5. A microscope is a precision instrument. Handle it with care and avoid subjecting it to sudden or severe

impact.

6. Make sure the instrument is earthed, to avoid lighting strike.

7. Do not disassemble any part of the microscope, especially the electrical parts on the bottom side as this

may result in electric shock.

8. Use the factory supplied power cord, please.

Maintenance and Storage

1. All the lenses have been well checked and adjusted. It is forbidden to disassemble them yourself.

2. The binocular viewing head and focusing unit have a compact and precise frame; please don’t disassemble

them as possibly as you can.

3. Keep the instrument clean, wipe dust regularly, and be attention to avoid contaminating the optical

elements especially.

4. The contaminations on the prism, as fingerprint and oil, could be gently wiped with a piece of soft cloth or

tissue paper, gauze which has been immersed in pure alcohol or ether. (Note that the alcohol and ether are highly flammable, do keep them away from the fire or potential sources of electrical sparks, and use them in a drafty room as possible as you can.)

5. Do not attempt to use organic solvents to clean the microscope components other than the glass

components. To clean them, use a lint-free, soft cloth slightly moistened with a diluted neutral detergent.

6. If the microscope is splashed by liquid during using, cut off the power at once, and wipe up the moisture.

7. Do not disassemble any parts of the microscope, which will affect the function or decline the performance

of the microscope.

8. Place the instrument in a cool, dry position. When not using the microscope, keep it covered with a dust

cover.

2.1. Assembly Diagram

The diagram below shows how to assemble the various modules. The numbers indicate the order of assembly.

 When assembling the microscope, make sure that all parts are free of dust and dirt, and avoid scratching

any parts or touching glass surfaces.

Page 6

Note:

Working Environment Requirement:

1. Ambient temperature: 5°C to 40°C. (41°F to 104°F),

Maximum R.H: 85°.

2. High Temperature will result in a mildewing, dew and even

ruinous instrument.

3. Avoid placing the instrument in a dusty environment. When

ending your microscope operation, please cover it with the dust cover.

4. Lay the microscope in a plan and stable position, please.

2.2.1. Mounting binocular head (Figure 1)

Loose the clamping bolt ③ on the pillar ④ and insert the binocular head and zoom body assembly ② into the bracket of the pillar, then screw down the bolt ③.

2.2.2. Mounting eyepieces (Figure 1, Figure 2, Figure 3)

Remove the eyepiece dust caps ① and gently insert two adjustable eyepieces ⑤ into the eyepiece sleeves until they stops, as in Figure 3.

2.2. Detailed Assembly Procedure

2.2.3. Connecting the power cord (Figure 4)

1. Clockwise rotate the left and right brightness adjusting

switches ① until the end on (off) state before connecting the power cord ②.

2. The power plug ② into the power jack of the

microscope; make sure the connection is well.

3. Plug the power cord ③ into the power supply

receptacle safely. Make sure the connection is well.

 Adjustable illumination for both LEDs (top and

bottom).

 Input Rating: 100V～240V.

2.2.4. Video (Photography) accessories assembly

1. Installing the video set: Remove the dust cap of the

trinocular viewing tube, revolve the camera set ⑤ into the screw thread end---the video adapter ④ with C mount, and insert the other end into the tri-through port and screw down the bolt ⑥.

2. Installing the photography set: Remove the dust cap of

the trinocular viewing tube, install the photography accessories ⑦ into the tri-through port, and screw down the locking bolts ⑥, change the camera ⑨ gun with digital photography adapter ⑧, and insert the adapter into the accessories, as in Fig 6.

3. ADJUSTMENT AND OPERATION

3.1.1. Adjusting interpupillary distance (Figure 7)

Different users have different interpupillary distances. So when users change, do the interpupillary distance adjustment. While looking through the eyepieces, hold the left and right of the binocular assembly ① and adjust the eyepieces by opening or closing them for binocular vision until the left and right fields of view coincide completely.

3.1.2. Adjusting diopter ring (Figure 8)

1. Set the diopter rings of both eyepieces to “0”position.

(Do this when users change, because different users have different diopters.)

2. Place an easy-to-observe specimen on the stage plate.

3. Rotate the zoom body knob ③ to the highest

magnification 4.5x, and turn the focusing knob ④ to focus the specimen.

4. Rotate the zoom body knob ③ to the lowest

magnification 0.7x, looking only into the left eyepiece, adjust the diopter ring on left eyepiece to focus the specimen. Then do the same thing for the right one.

5. Repeat item 3 and 4 until the specimen image can

always focus without any adverse effect of the changes of magnification on the definition of the image.

 The working distance of the microscope is 97mm, the

binocular head bracket ⑤ could be mounted onto the higher or lower position according to your needing. Remove the clamping bolt with provided hexagonal driver and move the bracket ⑤ down to the lower position and set it with original bolt (Figure 8).

3.2.1. Adjusting the rotation tension of the focus adjustment

knob (Figure 9)

1. Rotate the focus adjustment knob ① to move the slider

② to a lower place for fear that the zoom body drops

down suddenly if the tension is decreased too much.

2. Hold the focus adjustment knobs ① with both hands,

stop the left knob and rotate the right knob to increase or decrease the focus knob tension.

3. Rotate two sides of the adjustment knobs in the same

direction (otherwise it will get loose) to move the zoom body up and down to focus on the specimen.

3.2.2. Changing the magnification

1. The zooming knots located at two sides of the zooming

body could change the magnification of the specimen image.

2. Total Magnification = Magnification of zoom body ×

magnification of eyepiece

 While using the auxiliary objective, it should be

multiplied by its magnification in addition.

STEINDORFF

3.2. Focus Adjustment

3.3. Illumination (Figure 10)

1. Adjustable illumination for both LEDs (top and bottom).

2. Brightness adjustment: the right brightness adjustment knob ③ is used to adjust the bottom illumination,

and the left brightness adjustment knob ④ is used to adjust the top illumination. Each knob have its own on-off. Rotate anticlockwise to open the power, and continue would increase the brightness, keeping rotating clockwise would decrease the brightness until it is power off.
