4. Installation

4.1 Installation Condition

4.1.1 The required input voltage: 85V-265V, 50/60HZ

4.1.2 Alcohol, gasoline and paper all are burnt early, please take them away from the lamp.

4.1.3 The halogen lamp: 6V/20W, G4

4.1.4 The microscope should be used in environment of indoor temperature 0 °-40°C and maximum relative humidity 85%.

4.1.5 Please pay attention to prevent microscope from violent shake and vibration in application and in carrying. Don’t drag it on the surface of worktable to avoid damage to microscope and worktable.

4.2 Installation

4.2.1 Please confirm the installation condition meets 4.1;

4.2.2 Put out the main body and place it in table, and loose the main body fixing screw, then put the cost cover out;

4.2.3 Put out the intermediate, fix it into the main body, then tighten the main body fixing screw; if it is Transmitting & Reflecting Polarizer

Microscope, put out the reflecting illumination unit to fix it.

Installation of reflecting illumination unit: Put out the halogen lamp house, fix it onto the back of reflecting illumination unit by the fixed screw, connect the power wire of halogen lamp house into the power output socket of power house.

4.2.4 Fix the head into the intermediate;

4.2.5 Insert the eyepieces into the tubes;

4.2.6 Put out the dust cover of the nosepiece, and turn the coarse focusing knob to lower the stage, and find the objective hole with yellow mark in the nosepiece. Fix the 10X objective into the hole, and turn the nosepiece clockwise, fix the other objectives as per the power.

4.2.7 Loose the condenser lock thumb and fix the condenser.

5. Operation

5.1 Turn the power switch and the potentiometer to adjust light to be available;

5.2 Fix the sample on the stage, and move it into the path;

5.3 Turn the nosepiece to put 10X objective into light path, and turn the focus knobs to get clear image.

5.4 Confirm the polarizing vibrancy direction

The polarizing vibrancy direction has set to be at west-east in factory when the scale of the polarizing is 0°.

5.5 Check polarizing and analyzer

The field should be dark completely (when there is no sample) when the scale of polarizer and analyzer is 0°. Please check the position of the polarizer and the analyzer if not so.

5.6 Choose the complementary slip as per the sample, then insert into the slip.

5.7 Put into the Bertrand Lens Slip in the condition of polarizing;

5.8 Adjust the center of the stage.

6. Maintenance

6.1 Clean microscope

6.1.1 Don’t touch the lens with hand, Dust on lens should be cleaned by soft brush or absorbent cotton or cleaned by absorbent cotton, lens paper with the mixture of alcohol and ether (proportion 1:4).

6.1.2 Alcohol and ether all are burnt early, please take them away from fire. Be careful for turn on and off power.

6.1.3 Don’t clean painted metal and galvanizing metal with organic solvent such as alcohol, ether or the mixture of the both. Silicon cloth or soft cleaning preparation is suggested to clean it.

6.1.4 Plastic should be cleaned by soft cloth with clear water.

-8-

6.2 Environment of using and placing

6.2.1 Microscope should be used and placed in a cool, dry, non-dust, non-shake and non-corrosive gases environment.

6.2.2 Microscope should be used in environment of indoor temperature

0 °-40°C and maximum relative humidity 85%.

6.2.3 Removing equipment is suggested to be installed when microscope used in heavy humidity area to avoid fungus and mist damage instrument.

6.2.4 Please pay attention to prevent microscope from violent shake and vibration in application and in carrying. Don’t drag it on the surface of worktable to avoid damage to microscope and worktable.

6.3 Replacement of bulb

6.3.1 Turn off power, and pull out plug.

6.3.2 Wait the bulb become cool.

▲ Please be sure that the bulb is cool, then follow by the nest operations.

6.3.3 Lay aside the microscope reliably, unscrew the knurled thumb screw of the lamp housing cover on the underside of base.

6.3.4 Pull over the lamp housing cover.

6.3.5 Pull out the bulb should be replaced, hold a new bulb with silk cloth to avoid fingerprint and dust affect bulb brightness and service life, and insert fully the contact pins into the bulb socket.

6.3.6 Close the lamp housing cover, and screw the knurled thumb screw.

▲After working for above 10 hours continuously, better cut off the microscope about 30 minutes.

6.4 Replacement of fuse

6.4.1 Cut off power of microscope, and pull out the plug.

6.4.2 Unscrew fuse cap in the back of base, take out old fuse.

6.4.3 Replace a new fuse, then screw the fuse cap.

6.5 Stop to use microscope, please cut off power, cover the dust cover, and place it in a cool and dry environment.

7. Troubleshooting

In the period of using BK series microscope, if there is any trouble occurs, please referring to the following sheet listed some common troubleshooting resolve them.

Trouble Causation

Plug is unreliable

Remedy

Plug in again

Switch on but bulb dark

Bulb is broken Change bulb

Fuse is broken Change fuse

Bulb is flickering or brightness is unsteady

Brightness of view field isn’t enough or is

Uneven

Brightness of view field isn’t enough or is

Uneven

Image isn’t clear

(contrast or definition isn’t enough)

Bulb is unstable Insert it again

Bulb is broken Replacing bulb

Bulb specification doesn’t meet the requirement

Brightness isn’t adjusted correctly

Objective isn’t in correct position

The size of iris aperture is too small

Lens eyepiece,

(objective, condenser, light collector) has dust

Position of condenser is too low

Cover glass of specimen doesn’t meet the requirement

Cover glass of specimen isn’t in up direction

Surface of objective lens isdirty (especially it is easy for the front lens of

40X objective to dip in immersion oil)

Immersion oil isn’t used for 100X objective (oil)

Immersion oil doesn’t meet the requirement

Replacing bulb

Adjust rotation potentiometer

Make the objective in correct position

Adjust the size of iris aperture

Clean it

Higher condenser

Use required thickness cover glass (0.17mm)

Place specimen correctly

Clean it

Use immersion oil

Use immersion oil supplied by us

-10-

Trouble Causation

There is bubble in immersion oil

Size of iris aperture isn’t proper

Position of condenser is too low

Remedy

Clear the bubble way

Adjust the size of iris aperture

Readjust the position of condenser

One side of image is dark or image is moving as focusing

Objective isn’t in correct position

Specimen isn’t placed correctly

Objective touches specimen as changing low times objective to high times objective

Cover glass of specimen isn’t in up direction

Cover glass doesn’t meet the requirement

Image observed by two eyes aren’t in superposition entirely.

It is easy for eyes to be tired during observing

Interpupilary

Diopter isn’t adjusted correctly distance isn’t adjusted correctly

Make the objective in correct position

Place specimen levelly on stage and clip it with clamp

Place specimen correctly

Use required thickness cover glass (0.17mm)

Adjust interpupilary distance according to two eyes

Readjust diopter
