Electrostatic Protection
⚫Remove all conductive objects (such asjewelry, watch, etc.) on the device body before touching
the device, and touch the grounding metal bracket by hand to release the static electricity.
⚫It is suggested to wear anti-static suit to prevent damage to the equipment caused by static
electricity.
⚫When installing or maintaining the device, wear anti-static wristband or anti-static gloves. Make
sure that the wristband is tightly attached to the skin and is reliably grounded.
⚫It is forbidden to touch exposed circuit boards with bare hands. Static electricity generated by
human body may damage electrostatic sensitive components on circuit boards.
⚫When touching electrostatic sensitive components or devices, proper grounding measures must
be taken.
⚫Put electrostatic sensitive components into anti-static bags for protection.
⚫It is suggested to place humidifier in dry environment to maintain suitable humidity and reduce
static electricity generation.
Maintenance
⚫If the device is not working properly, contact the manufacturer. Do not disassemble or modify
the device in any way. (The company does not bear any liability for any problem arising from
unauthorized modification or maintenance).
⚫Properly preserve all theoriginal packaging materials of the device so that when problems arise,
the device can be packed with packaging materials and sent to the manufacturer for processing.
The company does not bear any liability for accidental damage during transportation caused by
non-original packaging.
⚫This device is a precision electronic device, no components can be maintained by user, do not

COE LS-X Line Scan Camera | USER MANUAL
disassemble the device arbitrarily.
Cleaning
Do not touch the image sensor directly. If the sensor needs to be cleaned, use a clean rag and wet
it with alcohol, then gently wipe off the dirt; if the device is not in use, cover the image sensor with
dust cover for protection.
Installation
Do not install the device on vibrating surface or places that are vulnerable to impact.

7Image Acquisition
7.1 Set Line Rate
Line rate refers to the image line number that is output by the camera per second. The frame rate of
the camera is proportional to the line rate, and is inversely proportional to the height of the image
area, that is, Fps = Lps (line rate)/Height (image height).
The following 4 factors determine the maximum line rate:
⚫Readout time: The shorter the readout time and the higher the line rate will be.
⚫Exposure time: The shorter the exposure time, the higher the line rate will be.
⚫Pixel format: The more bytes pixel format occupy, the lower the line rate will be.
⚫Bandwidth: The larger the bandwidth, the higher the line rate will be.
⚫Image compression mode: This function is used to compress data before transmitting
to the PC, and increase the frame rate to some extent.
In client software, click Acquisition Control >Acquisition Line Rate (Hz), and enter Acquisition
Line Rate (Hz). You can view real-time line rate and frame rate in Resulting Line Rate (Hz) and
Resulting Frame Rate (Hz) respectively.
Figure 1-8 Set Line Rate
When you enable the image compression mode (see section Set Image Compression Mode for
details), you can view Reference Line Rate (Hz) that stands for the min. line rate that is calculated
according to compression ratio.
