Working principles of the video microscope system

A clear picture of tiny object could be seen through the Microscope, then, such picture would be grabbed and turned into video signal by the CCD camera, and then, the video signal would turn into a digital picture on the LCD display, meanwhile, the video signal will be transformed in the signal transition box and then sent via the USD2.0 access to the computer for display, picture-grapping, photographing, measuring, saving and printing as well. Users can get the picture of ideal video effect by turning the zooming ring of the lens section.

Functions and features

1. Ideal effect pictures for users' comfortable watching.
2. Relieve the fatigue of and damage to the eyes results from long time watching via the microscope.
3. Clear pictures of high resolution, wide visible range and zoom range.
4. All-in-one integration design, smart size, space saving.
5. Simple and easy to operate, stepless zooming range.
6. With “+” scale, for measurement and orientation reference.
7. LED lamp is easy to fix and operate, stepless lightness adjustable.
8. Double halogen lamp, provide illumination from top & bottom, stepless lightness adjustable. (for PCE-VM 21)
9. USB2.0 access enables the connection to computer for display, picture-grapping, photographing, measuring, saving and printing as well.

Operation and usage

Installation: firstly, fix the fixing support of PCE-VM 23 lock in suitable place onto the working table, secondly, set the installed main body into the horizontal positioning axletree, thirdly, adjust the horizontal pole so that the lens aims at the testing objects, lastly, adjust the LCD display screen in a suitable visual angle; while PCE-VM 21 G & PCE-VM 22 G can be put on working table directly for instant use. Pull the power adaptor plug into the socket.

Turn on/off: connect the machine to the power source, the power indicator(button ⑧) will turn on, press button to turn on the display, meanwhile, the power indicator will turn off; when working, press the button to turn off the display, meanwhile, the power indicator will turn on..

Attention: Please pull out the plug cut the power supply when the equipment is not in use, otherwise the power adaptor, CCD and display will keep on working.

Adjusting:

1) Adjust the imaging: place the testing objects under the lens, loosen the vertical positioning bolt to adjust the height of microscope and make the distance between the object with the surface of lens is 100mm, and then adjust the focus adjusting cirque to make the image clear. Finally, turn slightly the upright positioning adjusting nut so that the lens will go up and down to zoom in and out, till get the image of the best effect.

2) Adjust the zooming times: turn the focus adjusting cirque to get

suitable zooming times.

3) Adjust the lightness: lightness plays an important role in imaging, weak lightness makes the image dim and not clear while strong lightness changes the original colors of the object's image. The more spectrums, the more vivid the imaging will be. Moreover, refraction of the light also affects the imaging quality. So the illumination and lightness have to be carefully chosen and adjusted.

Installation and usage of the LED lamp:

a. lock the LED lamp to the lens tightly. b. insert the plug of LED into correspondent access/socket. c. press button “/OK”, the correspondent mark appears in the right up corner of the screen, and the lamp is on. (direct pressing “+” or “-” will also turn on the LED lamp)

d. press "+" " -" to adjust the lightness. e. once the lightness becomes ideal, press button "OK" to confirm and quit.

f. When the LED lamp is on, press button “/OK”, the correspondent mark and the lamp will be off.

4) Adjust the parameters of the image & system setting: OSD can be adjusted via buttons. OSD includes "image" and "settings"." While "image" includes "brightness", "contrast", "saturation" and "hue", users can adjust these parameters at their wills. "Settings" includes "language", "scale", and "default".

"language": 9 languages available.
"scale": 10mm for a big graduation of scale while 5mm for a small one.
(Notes: the scale is just for reference only.)

“default”: recover the factory settings.

Image adjusting:

a. press "MENU" to enter into the sub-menu "image".

g. when adjustments finish, press button “OK” to confirm and quit. AV OUT (av signal outlet): enable the machine to be connected with exterior display for better watching.

Installation of USB2.0 display card

The system of PCE-VM 21\22\23 is equipped with USB/PC access (see picture 3), which enables it to be connected with computer and thus

extends its functions. For the first time using, the drive software for display card and operation interface software for computer should be activated/set up:

1. Check the computer's parameters and make sure they meet the requirements stated in the point "4.USB2.0 Display card in the "Requirements for computer system".
2. Connect the machine to computer via the USB2.0 access, and then activate the system.
3. Put the drive disk of USB2.0 display card into the computer's disk driver; finish the installation of the driving procedures according to the guide of Instruction of USB2.0 and computer indications.
4. After the driving procedures finished, click to activate the operation software, finish the installation of the USB2.0 display card according to the guide of Instruction of USB2.0 and computer indications.
5. After the above steps, check and make sure the installation is successful, and then computer operation can be stared.
   Note: For installation steps, please refer to "Installation of USB2.0 Driving Progress for the Video Microscope".

Dysfunctions diagnosis

1. Vague image:

Generally results from the improperly adjusted working distance, please re-check and make sure the working distance is approx 95mm as required.

1. Image is dim, unclear, colorless, red, and with "snow stains":

Generally results from weak lightness/brightness, please adjust lightness/brightness properly strong.

1. Image is too white:

Generally results from strong lightness/brightness, please adjust lightness/brightness to a properly extent.

1. Image with white spot:

Generally results from refraction of the light or strong lightness/brightness, please adjust the light incidence and the lightness/brightness to a properly extent. Normally, scattering light is a better mean of illumination.

1. No image appears on the display screen:

This may result from many factors, among which the most common two are display screen dysfunction and signal dysfunction. When this happens, first, check whether the power supply system is properly working or not; open the top cover of the machine, if the indicator of CCD camera is on, it means the power supply system is all right, then the below procedures should be followed:

(1) Display screen dysfunction: Normally, if the display screen is OK, press button ①, the caught image or the two-second "no signal" -14-

indication should be on the screen, otherwise display screen dysfunctions can be deemed affirmative. This symptom can also be judged from the exterior display connected via the AV OUT outlet.

(2) No signal dysfunction: When no signals are sent to the display, the backlight of the display screen will be off even it is power on, so no image appears on the screen. When this happens, please check the pass through which the signals are transmitted. Normally, the ocular microscope is deeded to be ok without outside force, and if the video signal transmitting wire is ok, then CCD camera will be

considered to arise.

Attention:

① If any dysfunction happens to CCD camera or display screen, please contact the supplier for repair.
② Please take care of the power supply voltage, wire polarity and the video format, if users want to change the CCD camera by themselves.

6. No image appears on computer

When the screen of PCE-VM 21/22/23oes well, but no image appears on computer, please check whether the computer works well or whether the system of the machine and the computer is properly connected or not, if affirmative answer comes, then the display card dysfunction is deemed to arise. When this happens, please open the top cover of the machine and check whether the indicator of the display card is on or not, and check if the connections between the card and the signal outlet as well as the video signal input are ok, if yes, then the display card dysfunction is confirmed to arise. Please contact the supplier for repair.

Note: High voltage inside, take care, please make sure the Electricity is cut off when checking.

WARNING

The display is vulnerable and may be damaged forever should its interior parts are changed by any means, to avoid which please let a qualified person to disassemble and fix the machine when faults and dysfunctions happen.
