Before using BS-6004 series

Inverted metallurgical microscope is used to discern and analyze organizational structure from kinds of metal. It is

very important in the work of quality research for foundry, smelt, heat treatment and inspection for raw material

and analysis for metallurgical structure of material after processing. It is also the important tool of research work

for metal physics, which is wildly used in enterprise, university and R&D.

1. Attention:

1.1 As the microscope is precision instruments, it should be

taken carefully and avoid impact during transportation.

1.2 Do not expose the microscope in the sun directly,

either not in the high temperature, damp, dusty or

acute shake place. Make sure the worktable is

horizontal. Following environment is required: Indoor

temperature: 5℃～40℃, Max relative humidity:80%.

1.3 To move the microscope, please hold groove ①

behind and tube position ② and lay it carefully. (Fig. 1)

★It will be damaged by holding the stage, focusing knobs, tube or illuminator.

1.4 The lamp will be very hot during working, please make sure there is enough space around for dissipating.

1.5 Please connect the microscope with ground to avoid lighting strike.

1.6 Please make sure the power switch is “0”(Off)(See the left Fig) and the bulb cool down before replace the

bulb or fuse.

★Bulb: 3W LED bulb (Standard)

12V/30W halogen bulb (Philips 5761) (Optional)

1.7 It adopt wildly voltage 90~240V, and do not need any transformer. Please make sure the power supply before

using.

1.8 Please use special wires supplier by our company.

2. Maintenance

2.1 Clean the lenses gently with a soft lens tissue. Carefully wipe off oil or fingerprints on the lens surfaces with

tissue moistened with 3:7 mixture of ethanol and aether or dimethylbenzene.

★Ethanol and Aether are both flammable. Please leave them away from fire or fire source, especially during

the power switch turn on and turn off.

2.2 Don’t use organic solution to clean the surfaces of the microscope, especially for plastic parts. Please use the

neutral detergent if necessary.

2.3 If the microscope damped by the liquid during working, please cut off the power immediately and make it

dry.

2.4 Do not disassemble or assemble the microscope to avoid damaging the capability.

2.5 After using, put on dust cover to protect microscope.

3. Safety sign

Sign

Signification

It shows the surface gets hot and don’t touch with bare hand.

Read the introduction before using. Unsuitable operation would lead person

hurt or instrument faulty.

2-2 Assemblage step

2-2-1 Set lamp holder

b Make sure the pin ① and ③ facing to the hole ② and ④,

then lock. (Fig. 2)

★LED bulb: 3W

★Halogen bulb: 6V30W (Philips 5761)

2-2-2 Set or replace bulb

Use clean glove or gauze to hold the bulb and make sure the

bulb pin ① facing to hole ③ and lock. Please make sure the

bulb should be vertical. (Fig. 3)

★Do not touch the bulb by finger directly.

Clean by gauze if there is finger print on bulb.

★Whenever replace the bulb, please cut off the power first

and wait the illuminator part cool down.

2-2-3 Set objectives

Turn the coarse knob to make the nosepiece to lowest.

Through the hole on stage to set the objectives ① on

nosepiece from low magnification to high magnification with

the direction. (Fig. 4)

★Clean the objectives regularly. It is very sensitive of dust

for objective of Inverted microscope.

★Please use low magnification objective, such as 5X or 10X

to find image, then use high one for observation.

★Make sure to hear click when turning to show the

objective on correct position.
