USER NOTICE BS-2053, 2054

Ⅰ. Safety Notice

1. Open the box carefully to avoid the accessories, like lens, dropping to ground or being damaged.

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

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

3. When moving the microscope, carefully carry it with the handle and the base.

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

5. For safety, be sure the main switch is in “O” (off) state and cut off the power supply before replacing the bulb

or the fuse. If you replace the bulb during use or right after use, allow the lamp bulb and the lamp house to

cool completely before touching.

Designated bulb: 1W S-LED Lamp (BS-2053); 3W S-LED Lamp (BS-2054).

6. 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.

7. Always use the power cord provided by We.

8. The electrical equipment of the microscope should be discarded as electronic waste.

II. Maintenance and Care

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

2. The nosepiece and 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 element when wiping away the dust on the

instrument.

4. The contaminations on the prism, like fingerprints and oil smudges, 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. When using, if the microscope is splashed by liquid, cut off the power at once, and wipe away the splash.

7. Do not disassemble any parts of the microscope, as this will affect the function or reduce 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. Make sure the lamp socket is cool before covering the microscope.

Ⅲ. Configuration Instruction

1. BS-2053 is the basic model and uses NIS45 system;

2. BS-2054 is the coding model, using NIS45 system, with brightness memory, adjustable color temperature

stage and other configurations.

IV. Safety Marks

2.1 Assembly Diagram

Taking BS-2053 for example, the following figure shows the installation sequence of the components. The

number in the figure shows the assembly steps. The installation method of BS-2054 is the same as that of

BS-2053.

Before installing, be sure every components is clean, do not scratch any parts or glass surface.

Keep well with hexagon wrench provided. When changing the components, you will need it again.

2.2 Assembly procedure

2.2.1 Installing the eyepiece (Fig1)

Insert the eyepiece into the eyepiece tube until they

are against each other, as shown in Fig1.

2.2.2 Installing the objective lens (Fig.2-4)

1. Adjusting the coarse focus knob until the support

device of the mechanical stage reaches its stop limit

position.

2. Screw the lowest magnification objective into the

nosepiece from the left or the right side, then

revolve the nosepiece clockwise and mount other

objectives by the sequence of low to high

magnification

Installing objective this way will make the change of

magnification to be easier during using.

Clean the objective regularly, for lens is susceptible

to dust.

When operating, use 10×magnification objective to

search and focus specimen firstly, then replace with

higher magnification objective if necessary.

When replacing the objective, slowly turn the

nosepiece until you hear “clicked”, that means the

objective is in place.

BS-2054 Model: Turn on the power supply. The

corresponding objective magnification on the LCD

screen will be highlighted (as shown in figure 4)

when the nosepiece moves to a certain position.

Then install the corresponding objective at this

location.

2.2.3 Mounting the filters (Fig.5)

1. Open the condenser carriage①;

2. Place the required filter②into the condenser, then

close the condenser carriage.

★The filter of the standard outfit is green and baby

blue.

2.2.4 Connecting the Power Cord (Fig.6-7)

1. Set the main switch①“O” (off) state before

connecting the power cord.

2. Insert a section of the adapter plug② DC socket

connector ③of the microscope safely to ensure good

contact.

3. Insert the other end of the adapter plug into the

common power socket to ensure good contact.

★Do use the supplied adapter all the time. If lost or

damaged, select the same standard adapter, please.

★A wide range of voltage, like 100V ～240V, is

acceptable for this microscope.

2.2.5 LED lamp replacement (Fig.8-10)

◎Generally, LED lamp is very durable, so it is not easy to

damage. If it is unfortunately damaged, please

purchase the LED (Fig.10) from your vendors.

1. Loosen the screw I of brightness adjustment knob to

take the brightness adjustment knob down (Ignore

this note for BS-2053 model). Loosen six screws of the

bottom plate to open the bottom plate①;

2. Loosen screw② to take the LED lamp③ down and

unplug the connector A from the breadboard. Mount

new LED lamp, tighten screw② and insert the

connector fully into the breadboard.

★Note: Be careful to take the bottom plate down

slowly in case that the wire inside the microscope is

pulled apart.
