WECG400
Parallel Testing ECG Tester
for wearable device production lines
Quick Start Guide

Hardware Overview

Dimensions (W x L x H): 270 x 225 x 50 mm
Note: The WECG400 is rack-mountable with the 1U height (excluding the foot pads) design.

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 object1.
2. Connect the RA, LA, and RLD electrodes of DUTs respectively to the RA, LA, and RLD electrode terminals on the WECG400.
3. Connect a computer to the WECG400 using a USB Type-A to USB Type-B cable.
4. Plug 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.
5. Activate the installed WECG400 software to conduct parallel or sequential testing2.
   Note: 1. For more information on grounding, please refer to Notes for Installation – Reduce environmental noise interference.
   2. For more information on testing, please refer to Operation.

Operation

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.
• Parallel testing
  1. Set the input impedance of the WECG400 to 10MΩ through PC.
  2. After connecting 4 DUTs to the WECG400, switch the WECG400 to the desired input impedance value and choose the test item.
  3. The WECG400 will simultaneously send signals to the 4 DUTs. After the test is complete, switch the input impedance of the WECG400 back to 10MΩ.
  4. Disconnect the tested DUTs and repeat the above steps for further testing.
  Note: Set the input impedance of the WECG400 to 10MΩ before each test can minimize the impact of electrostatic discharge (ESD) and surges from DUTs on the WECG400 and test results.
• 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.
  Note: If there is excessive noise during sequential testing, parallel testing is recommended.

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.
