User Notices

I. Safety note

i. When unpacking, please take care not to drop fragile items, such as lenses.

ii. Keep the instrument out of direct sunlight; avoid high temperatures or humidity, dusty environments. Make sure the work

surface is stable and away from sources of vibration.

iii. Take care when moving the instrument, using two hands to grip with the sides of the microscope body.

iv. Caution! The lamp house and nearby parts will be very hot during operation. Ensure sufficient space to allow cooling.

v. Before replacing the halogen lamp, or fuse, make sure the main switch is in the “O” (off) position, and turn off the mains

power. Allow the lamp bulb and lamp house completely cool before removal.

vi. Use the factory supplied power cord.

II. Maintenance

i. Do not disassemble any parts of the microscope, as it will affect function, or reduce the performance.

ii. Keep the instrument clean and cover with a dust cover when not in use. Remove dust with a lint-free cloth. Take care to

avoid contaminating the optical elements.

iii. Marks on the prism, such as finger marks or oil should be removed by gently wiped with a piece of lint-free cloth immersed

in pure alcohol or xylene (NOTE: alcohol and xylene are highly flammable. Keep away from heat sources and use them in a

well-ventilated room).

iv. Do not use organic solvent to wipe the non-optical elements.

v. Place the instrument in a cool, dry environment. After using the microscope, cover with a dust cover.

Wait for the lamp house to cool completely before covering.

2-2 Installation Steps

2-2-1 Installing the mechanical stage support

Before installing the device, be sure to adjust the coarse focus

control ①. Move the guide board ②down to the lowest

position, so you can install the mechanical stage support device

easily.

Hold on to the mechanical stage support device (Fig.2). Place it

from the top of the guide board (Fig.1), until the stage reaches the

lowest position. Use the Allen key provided to secure the stage

③.

The mechanical stage ⑤has been adjusted before

leaving factory. Do not disassemble.

Assembled parts should look like Fig.3.

2-2-2 Installing the reflected light brightfield /

darkfield illuminator

Install the reflected light illuminator (Fig.4) on the head of the

microscope body (Fig.5) and then secure the bolt ⑥.

2-2-3 Installing the trinocular head

Insert the video port (Fig.6) into the illuminator (Fig. 4), and then

secure the bolt.

2-2-4 Installing the objective

1. Adjust the coarse focus knob until the support device of the

mechanical stage reaches its lower limit position.

2. Place the lowest magnification objective onto the nosepiece

from the left or the right side and then push the nosepiece

clockwise. Then place other objectives in the sequence of low

to high magnification (Fig.7).

When replacing the objective, slowly turn the

nosepiece until you hear a “click”. The objective will

now be in the required position-(the centre of the

light path).

2-2-5 Installing the Trinocular tube (optional)

Insert the video port (Fig. 8) into the trinocular unit (Fig. 6), and

then screw down bolt ⑨to fix it into position.

2-2-6 Installing the Eyepiece

Insert the eyepieces (Fig.9) into the eyepiece tube until they are

flush with one another, ensuring the edges meet.

2-2-7 Installing the Lamp Housing

1. Gently push the lamp holder (Fig.10) into the illumination kit

(Fig. 4) turn it to the correct position, and then screw down

bolt ⑧to fix it into position.

2. Insert the power plug ①into the jack socket ②, and screw

in the bolt.

Remember to remove the dust cap before you use

the transmitted light illuminator. Attach the lamp

holder (Fig.10) into the jack socket on the back of

the microscope (Fig.11) taking care when moving

this object into position, and then secure bolt ④.

Insert the power plug ①into the power jack of the

microscope ③, and screw down the bolt to fix it into

position.

2-2-8 Attaching the Halogen Bulb

The appropriate lamp bulb is: 24V100WHAL.

1. Loosen the clamping screw ①at the top of the lamp housing

using the provided Allen key.

2. Lift the lamp housing ②to remove it.

3. Tilt the bulb socket by 90°(Fig. 14)

4. Remember to wear gloves or use a piece of gauze

when handling halogen bulbs. Push the bulb clamping

levers down, and take care while you insert the bulb pins into

the socket as far as they will go.

Then return the bulb clamping lever gently back to the original

position.

Caution!

–DO NOT replace bulb during or directly after use

Be aware that during use and directly after the equipment has been

turned off, the lamp, the lamp housing and nearby parts will be

very hot and could cause serious burns. Please make sure the main

switch is turned off “O” (off), and pull out the power cable. Make

sure the bulb, the lamp housing are cool before you start replacing

the bulb.

Please insert the lamp gently, or it will be damaged

by excessive extrusion.

Do not touch the Halogen bulb with your bare hands.

It will shorten the service life or cause it to burst. If

you leave finger marks on the surface, clean it with a

dry soft cloth.

Please pay attention to the warning signs. The

temperature of the lamp housing surface will be very

hot, and can cause serious damage.

3. Operation

3-1 Turning on the Lamp

Connect the power cable and turn the main switch ①to the “I”

(on) position.

When using transmitted light illumination, fix the

lamp holder into the jack on the back of the

microscope (Fig.11), and insert the power plug into

the power jack of the microscope (③in Fig.11). Then

turn the main switch ①to the “‖” (on) position.

3-2 Adjust Brightness

To adjust the brightness, turn knob ②clockwise to increase the

voltage therefore increasing the illumination; and turn

anti-clockwise to turn down the voltage and dim the light.

Using the lamp at low voltage, will prolong the life

of the halogen bulb.

3-3 Adjusting the Tension Adjustment Collar

The tension adjustment collar was adjusted before

leaving the factory, if you find it loose or if the

mechanical stage drops by itself because of weight,

please use the tensioning adjustment tool and adjust

the collar ③until the tightness is corrected.
