Ⅰ. Safety Symbols

Ⅱ. Safety Notes

1. Open the box carefully to avoid the accessories, like lens, being polluted by fingerprint or

sweat strain, dropping to ground and 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 smooth, horizontal and firm enough.

3. When moving the microscope, one hand hook into the upper slot behind the frame, and the

other hand hold the front bottom of frame.

4. If the bacterium solution or the water splash to the stage, objective or viewing tube, pull out

the power cord at once, and wipe up the microscope. Otherwise, the instrument will be

damaged.

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. Check the input voltage: be sure the input voltage which signed in the back of the

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

instrument.

Ⅲ. Maintenance

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

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, wipe dust regularly, and be attention to avoid contaminating the

optical elements especially. The objective lenses should be cleaned every month by professional.

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

the tissue 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. Don’t use organic solvent to wipe the non-optical elements, when you need to clean, use

the soft detergent, please.

6. When using, if the microscope is splash by liquid, cut off the power at once, and wipe up the

moisture.

7. Do not disassemble any parts of the microscope. That will affect the function or decline the

performance of the microscope.

8. Place the instrument in a cool, dry position. After using the microscope, remember to cover

it with dust helmet.

3. Adjustment and Operation

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

Connect the power, turn on the main switch

on the back of microscope (figure 1) to “-”(on).

3-2 Adjust the brightness and switch up

and down illumination (Fig.2)

Turning the brightness adjustment knob

according to the direction indicated by an arrow

on the figure 2, the brightness strengthen. On the

contrary, the brightness decreases.

As shown in figure 2, when the switch lever

is push-in, the light on the top is on, the symbol

is ; When the light switch button is

push-out, the light on the bottom is on, the

symbol is .

3-3 Light socket (Fig.3)

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

socket and plug. Before the plug is inserted into

the socket, the direction should be adjusted until

their red dots are aligned.

The symbols on the left and right sockets are

corresponding with the switch button of light

source. As shown in the figure, is the

socket of upper light source, which is

corresponding with the state of pushing in the

knob of switching light source. is the socket

of lower light source, which is corresponding with

the state of pushing out the knob of switching

light source.

If the upper and lower light source switch

button is inconsistent with the state shown

in the diagram. Check the light source plug

and make sure the plug is plugged into the

appropriate socket.

3-4 Placing the Specimen (Fig.4)

Pull out the movable claw, put the specimen

in the corresponding slot, loosen the movable

claw and clamp the specimen.

★Be careful when changing the objective. When

the objective needs to be replaced after

observing the specimen with a short working

distance objective, the objective may collide with

the specimen.

3-5 Adjusting the interpupillary distance

(Fig.5)

The interpupillary distance range: 47mm～

78mm. While looking through the eyepieces,

adjust for binocular vision until the left and right

fields of view coincide completely.

3-7 Focusing (Fig.7)

1. When camera is not used Push the light path

selector rod (as shown in Fig. 6) in completely

and observe with binocular eyes. Use 10 × In

order to prevent the specimen from colliding

with the objective, the electric stage should be

raised first to make the specimen close to the

objective, and then the focusing hand wheel

should be rotated slowly and reversely to make

the specimen descend, and at 10 × Search the

image in the eyepiece, and then press the speed

control button to switch to the low rate focusing

gear for fine adjustment. At this time, the lens

can be converted to other magnification

objective to achieve focusing without damaging

the specimen.

2. When camera is needed, push the light path

switch selector rod (as shown in Fig.6) to the end

for binocular observation. After the image is

clear, pull it out again for observation through

the camera system.

The hand wheel buttons on both sides work

independently, and different focusing speeds

can be set respectively. The speed gear is

displayed on the touch LCD screen.

3.Focus upper limit

In actual use, if you want to limit and lock the

stage height, that is, the upper limit position of

focusing according to the situation, you can set

the temporary upper limit position on the touch

screen. Please refer to the touch screen manual

for detailed operation instructions.
