MEC 880 Waveform Copier

Photographs screens!! Easy-to-use CCD Camera with Built-in Printer

Waveform copier MEC880 is a camera with a built-in printer, which can be used for photographing with oscilloscopes and other equipments. The MEC880 is 100% digitized, using CCD (charge coupled device). Input images are immediately output to the printer. Eight different camera hoods are available, ensuring that the camera fits the individual screen size of each subject.
Even if your device has a print function, considerable time is often required to locate your printer and connect cables. With the MEC880, you can obtain a printout of your screen anywhere, and from any source. Moreover, operating costs are just 1.9 US¢ per sheet.


Fully Digitized Device Means More Functions

Normal photographing (NORM Mode)

Simply press the START key.   /   Printing will be completed in 20seconds.


Multilayer photographing (Overlap)

Press the MODE and START keys simultaneously. Output will overlap the previous and current images. Repeat as many times as desired.
The image at the right is an example of a three-layer photographing.


Slow scanning screen photographing (SL and SGL Mode)

The shutter speed in the NORM mode is 1 / 6seconds. For example, if an oscilloscope sweeps at a rate of 2ms / div or slower or at single scan mode, the screen will be cut off. In this case, use the SL and SGL mode. Press START to take a photo, then press again to finish.

Auto Power On and Off Function
To prevent the built-in batteries from being exhausted quickly, power is automatically turned OFF three minutes after printing or after the last key operation. Power supply can then be resumed by pressing any key.

Print Color (Reverse black and white)

BRIGHT: Print black where the original subject is bright and white where the original is dark.
[Application] Photographing of CRT, such as an oscilloscope.


DARK: Print white where the original subject is bright and black where the original is dark.
[Application] Photographing of a Liquid Crystal Display (LCD)


B and D: Print black where the original subject is either bright or dark, and white where the original is neither.
Appropriate for emphasizing outlines.
[Application] Photographing of electronic device, printed circuit boards, and small units.


BRIGHT        DARK      B and D

Print Density (DENS)
If there is insufficient light, the print will be somewhat colorless. Change DENS to obtain a better image quality.


DENS1     DENS4     DENS7

Warning Messages
INTEN: When the subject is too bright, the green LED indicator flashes.
: When the power level of the built-in batteries is low, the green LED indicator flashes.
: When the printer runs out of paper, the green LED indicator flashes.
:When the printer head is overheated, the green LED indicator flashes.


Data recording in a laboratory / environmental experiment room
Recording as much of the experimental process as possible, and recording waveforms that vary according to the ambient conditions, will make the process more efficient and make it possible to create better quality products.

Submitting quality control data to customers
Images are more credible and convincing than numbers. With the MEC880, the time and cost required to obtain data are also significantly decreased.

Data and materials for meetings called to solve problems
Working with others is often the best way to solve those problems that you can 't solve on your own. But meeting require adequate data, which is usually better presented visually, rather than in numeric form. The MEC880 makes this easy to do, while, at the same time, keeping costs to a minimum.

Collecting customer data and gathering data outdoors
Carrying a lot of equipment around while visiting customers is inconvenient. However, you need to gather vital information. On such occasions, the MEC880 is your best choice.

Rolled paper eliminates the need to put page numbers (on each page)
Using sheet paper requires the addition of page numbers, so that sheets will not get lost. This is time-consuming. Using rolled paper means that you won 't need to spend time adding page numbers, but can still indicate the page order.

Capture printed matter

You need a photocopy of a newspaper or other printed material, but no copier is available. The MEC880 makes it easy for you to take a picture.
