I. Safety Symbols

The following signs are on the microscope. Figure out what these symbols meanings and always use the

microscope in the safest way.

II. Safety Precautions

1. Be careful when moving the microscope, to avoid the lens glass sticked by fingerprints and sweat stains

for the sake of observation, to avoid the lenses dropped or damaged.

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

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

3. Hook into the upper slot behind the rack by one hand, and hold the front bottom of the rack by the other hand

when moving the microscope.

4. If the carrier, objective or viewing tube is spilled with bacteria or solution, you should immediately pull out the

power wire and dry the solution or water to ensure that the microscope is dry. Otherwise, it is possible to

damage the instrument.

5. Be sure to keep at least 10cm away from the left, right, top, rear of the microscope from walls and other objects,

so as not to plug natural convection air, which is used for cooling.

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

7. is used to ensure safety, you should make sure the main switch is in "O" (off) state and cut off the power

supply before replacing the bulb or the fuse. Check the input voltage: Be sure the input voltage which is signed

in the back of the microscope is consistent with the power supply voltage, or it will bring a serious damage to

the instrument.

8. Use the special wire provided by our company.

III. Maintenance

1. All the lenses have been adjusted properly; Please do not dismount them by yourself.

2. The nosepiece, coarse and fine focusing parts are so delicate that it is forbidden to disassemble them carelessly

by yourself.

3. Keep the instrument clean, and do not pollute the optical elements when wiping away the dust on the instrument.

The objective lenses should be cleaned once every other month by professional.

4. We can clean the contaminations such as fingerprints and oil smudges on the prism by using the Lens paper and

solution, which is mixed by ether(70%) and alcohol(30%).

Noting that 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.

Using neutral detergent to clean them.

6. You should cut off the power immediately and dry it if the microscope is wetted by the liquid when using the

microscope.

7. Do not try to disassemble any part so as not to affect functionality or lower the performance of the microscope.

8. The instrument should be kept in a cool, dry place and should be covered with a dust shield when not be used.

Cover the microscope after the lamp cooling down.

9. Working environmental requirements:

a) Indoor use; b) Temperature range:10℃~35℃;

c) Maximum relative humidity: when the temperature reached 31 ℃ is 80%, linear reduction of temperature

to 34℃ is 70%, when the temperature reached 37℃ is 60%, when the temperature reached 40℃ is 50%.

10. Storage and transportation requirements:

a) Temperature range: -40℃~+70℃ b) relative humidity range: 10%~100%

c) Atmospheric pressure range: 500hpa～1060hpa

warning:

endangered but also the microscope will be damaged. The microscope shall always be operated in accordance with

this instruction.

◎ This microscope will not cause radiation, electromagnetic interference and other phenomena to the

1. Components Name

The main difference between BS-6024RF/TRF and BS-6025RF/TRF is that BS-6024RF/TRF is manual microscope, BS-

6025RF/TRF has motorized nosepiece. BS-6024RF and BS-6025RF only have reflected illumination, BS-6024TRF and

BS-6025TRF have reflected and transmitted illumination, we will mainly introduce the operation of BS-6025TRF,

other models can refer to BS-6025TRF.

3-1 Turn on the power (Fig.1)

Turn on the power, change the main switch on the

back of microscope (as shown by the Fig.1) into "-"

(power on) state.

3-2 Light intensity adjustment and upper & lower

light source switch (Fig.2)

As shown by the arrow in Fig.2, The light fades as the

button rotates. Instead, the light enhances.

As shown in Fig.2, when pushing the switch bar of up

and down light source, the upper light source is

lighting, the symbol is ; when pulling out

the switch bar of up and down light source, the

down light source is lighting, the symbol is

3-3 Light source socket (Fig.3)

As shown in Fig.3, there are red dots in the socket

and plug, the direction should be adjusted before

the plug is inserted into the socket, and red dots

should be inserted in alignment. When hearing

"click", it means ok.

Noting screen prints on the left and right socket

corresponds to switch levers of up and down light

source. As shown by the Fig: means light

socket of up light source, which corresponds to the

pushed state of switch bar for up and down light

source; means light socket of down light

source, which corresponds to the pulled state of

switch bar for up and down light source.

3-4 Specimen preparation and placement (Fig.4, Fig5)

1. The specimen (Num② in Fig.4) for observation is fixed

on the sample plate (Num① in Fig.4) by use of silly putty

(Num③ in Fig.4), and ensure the specimen surface is

parallel to the sample plate. You can use the nipping

machine to press the sample. (as shown in Fig.5).

2. Place the sample plate of the fixed

specimen on the microscope stage.

Be careful when replacing the objectives, after the

specimen was observed with a short-range objective lens,

the objective may collide with the specimen when it is

need to replace the objective.

3-5 Pupillary distance adjustment (Fig.6)

The distance range between the pupils is 47mm～78mm.

When observing, we adjust the distance between the

pupils by holding the right and left prism eyepiece tube,

rotating around the axis until both left and right field of

view combined and feel comfortable.

3-7 Focusing (Fig.8, Fig.9)

1. When no cameras are used:

Push-pull rod (as shown in Fig.7) is completely pushed. When binocular

observing, you can use 10× objective to focus. To prevent the specimen

from colliding with the objective lens, The mechanical stage should be

raised, which brings the specimen close to the objective, then slowly

reverse rotation of the coarse focusing wheel so that the specimen could

be down, meanwhile, you can search the image in the 10× eyepiece, finally

you can focus to clear with the fine focus hand-wheel. At that time even if

you convert to other multiplier objective, the specimen can reach the same

focus without any damage.

2. When Photographic devices are used:

Push-pull rod (as shown in Fig. 7) is completely pushed. Making binocular

observations, when the image is clear, then pulled it out, then it can be

observed by the camera system.

 The fine focusing hand wheels on both sides are held by magnets for easy

removal. All you need is the arrow shown in the Fig.9, Press one end of

the hand wheel inward to make the other curl, then gently pull off the

end of the cock, so hand-wheel is easily detached. Assembly also needs

only hand wheel center alignment put in. This function makes the two

fine-tuning hand wheels conveniently inter changeable, to avoid fine-

tuning hand-wheel and platform handle collision.

3-8 Adjust the tightness of the focusing hand-wheel (Fig.9)

The rotation direction is shown in the Fig.9, the more rotation, the tighter

the focusing hand-wheel is. On the contrary, the less rotation, the less tight

the focusing hand-wheel is.
