Before Use A15.0908 Series

1. Operation Notice

1. As the microscope is a high precision

instrument, always operate it with care, and

avoid physical shake during the operation.

2. Do not expose the microscope in the sun

directly, either not in the high temperature, damp,

dust or acute shake. Make sure the worktable is

flat and horizontal. Following environment is

required when operating: Indoor temperature: 5

℃～40℃, Max relative humidity: 80%.

3. When moving the microscope, use one hand to

hold its front base and the other hand to hold its

arm, and lay it down carefully (See the Fig. left).

★It will damage the microscope by holding

the stage, focusing knob, head or light source

when moving.

4. When working, the surface of light source will

be very hot. Make sure there is enough room for

the heat dissipating around the light source.

5. Connect the microscope to the ground to avoid

lightning strike.

6. For safety, make sure the power switch is at

“O” (OFF) and power it off before replacing the

bulb or fuse (See the Fig. left), and wait until

both the bulb and bulb holder have cooled down.

★Bulb selected only: 12V/50W Halogen bulb.

7. Wide voltage range is supported as 100~240V.

Additional transformer is not necessary. Make

sure the voltage is in this range.

8. Use the special wire supplied by our company.

2. Maintenance

(1) Wipe the lens gently with a soft tissue. Carefully wipe off the oil marks and fingerprints on

the lens surfaces with a tissue moistened with a small amount of 3:7 mixture of alcohol and

ether or dimethylbenzene.

★As the alcohol and ether is flammable, don’t place these chemical near to fire or fire

source. For example, when turning on/ off the electrical device, please use these chemical in

a ventilated place.

(2) Don’t use organic solution to wipe the surfaces of other components. Please use the neutral

detergent if necessary.

(3) If the microscope is damped by liquid when using, power it off immediately and wipe it dry.

(4) Never disassemble the microscope, otherwise the performance will be affected or the

instrument will be damaged.

(5) After using, cover the microscope with a dust cover.

3. Safety Sign

Sign Signification

The surface gets hot and don’t touch it with bare hand.

Study the instructions before use. Unsuitable operation would lead to

person hurt or instrument faulty.

2-2 Assembling Steps 2-2-1 Assemble and Replace the Halogen Bulb

◎For Transmitted Illumination

When assembling the halogen bulb for transmitted

illumination, hold the bulb①with clean glove or

tissue and insert the pins②into the receptacles③.

Make sure the bulb is vertical (See Fig. 1).

◎For Reflected Illumination

(1) Loosen the lock screw①with the M4 inner

hexangular spanner which is equipped with the

microscope, to take off the cover group (See Fig. 2).

(2) Open the bulb lock sheet②, hold the bulb③with

clean glove or tissue and insert the pins④into the

receptacles⑤. Make sure the bulb is vertical (See Fig.

3).

(3) Loosen the bulb lock sheet②to lock the bulb,

and put on the cover group.

★Before replacing, cut off the main power supply,

and wait until the bulb and bulb holder have

cooled down.

★Bulb selected only: 12V/50W HAL Bulb(Philips

7027).

★Don’t touch the bulb with fingers. If there is

fingerprint on it, clear it with clean tissue.

2-2-2 Assemble the Light Source Group

◎For Transmitted Illumination

Match the guide pins①of bulb base with the guide

receptacles②of microscope body, and push the light

source group into the microscope body thoroughly.

(See Fig. 4)

◎For Reflected Illumination

(1) Fully loosen the lock screw①of the reflected

illuminator. (See Fig. 5)

Fig.3

A15.0908 Series

(2) Push the light source group base②into the

reflected illuminator light source base③thoroughly,

then lock the lock screw①.

2-2-3 Assemble the Condenser (With Polarizer Group)

◎For Transmitted Illumination

(1) Rotate the coarse focusing knob①to raise stage

to the highest. (See Fig. 6)

(2) Rotate the condenser up-down knob②to move

the condenser bracket to the lowest.

(3) Loosen the condenser lock-screw③fully.

(4) Swing out the front lens of condenser④with the

scale forward. Make the lock screw⑤of condenser

in alignment with the groove⑥of the condenser base.

Push the condenser into the innermost of base.

(5) Screw down the condenser lock screw, and raise

the condenser to the highest position with the

condenser up-down knob.

2-2-4 Assemble the Stage Clip

Plug the two stage clip pins①into the hole②on

rotatable stage thoroughly. (See Fig.7)

When using the moving stage, plug the two φ3mm

forelocks into the two holes②, and lock them on

stage with M4 screws.

★ Adjust the handle to “60” reticle (to “0”) when

using the moving stage on X-axis, to avoid

hurting objectives.

2-2-5 Assemble the Objective

Rotate the coarse focusing knob to lower the stage.

Screw the 10X objective into the hole of nosepiece

with red mark, then install the objectives into the

nosepiece from the lowest magnification to the

highest in a clockwise direction. (See Fig.8)
