Installation
①(Optional) Ground the WECG400 by connecting one end of a grounding wire to the GND terminal and the other end to a
suitable grounded object 1.
②Connect the RA, LA, and RLD electrodes of DUTs respectively to the RA, LA, and RLD electrode terminals on the WECG400.
③Connect a computer to the WECG400 using a USB Type-A to USB Type-B cable.
④Plug a power adapter into an AC power source, then plug the power adapter cable into the WECG400's power jack. Now
the WECG400 is powered on.
⑤Activate the installed WECG400 software to conduct parallel or sequential testing2.

Operation
•Parallel testing
Connect 4 DUTs to the WECG400, then choose the test items through PC to send signals to the 4 DUTs
simultaneously.
•Sequential testing
1. Connect the first DUT, then choose the test items and the DUT through PC to send signals to it.
2. Connect the second and third DUTs, then choose the DUTs through PC while the first DUT is under testing.
3. After completing testing on the first DUT, the WECG400 tests other DUTs one at a time by users' designated
order.
4. Disconnect the tested DUTs, then connect new DUTs to the WECG400 and repeat the above steps.
Before starting the testing:
•The WECG400 supports both parallel and sequential testing, and users can develop programs by using SDK to
set up suitable testing methods.
•The WECG400 is not a standalone model. Please connect the WECG400 to a PC/laptop to conduct testing.

Notes for Installation –Reduce environmental noise interference
Note:
1. Shorter cables are recommended by bringing a closer connection between the
WECG400 and DUTs to reduce possible interference.
2. The metal plate's size should cover the WECG400 and the PC at least. It's unnecessary
to ground the metal plate itself.
•Use short cables to connect the WECG400 and DUTs1.
•Use shielded cables to avoid environmental radiation interference.
•Avoid cables overlapping or crossing each other when testing.
•Put a metal plate under the WECG400 and the PC,
then ground the WECG400 by connecting its GND
terminal to the metal plate.2
