WECG400

The first parallel testing ECG tester designed for production lines can simultaneously test ECG function on up to 4 wearable devices with a single computer to accelerate testing time.
This tester provides IEC 60601-2-47 test items and outputs 7 types of standard ECG waveforms to assist DUTs in conforming with regulatory requirements.
For customized testing, the raw data playback function can reproduce clinical data or user-defined waveforms to help users verify that the DUTs meet the manufacturer's specifications. This tester integrates needed equipment to optimize testing efficiency while ensuring product quality and a stable production process. It’s suitable for manufacturers who have mass-production needs on wearable devices with the ECG function.
Compliance tests conforming with IEC 60601-2-47, China YY0885, and YY 9706.247-2021

Overview

  • Integrates IEC 60601-2-47 test items*, including dynamic range, input impedance, frequency response, etc.
  • Equipped with 4 sets of electrode terminals - RA/LA/RLD electrode terminals on each set to meet testing needs for wearable device's ECG function
  • Outputs 7 types of standard ECG waveforms - ECG Waveform, Sine, Triangle, Square, Exponential, Rectangle Pulse, and Triangle Pulse
  • Provides SDK - users can flexibly develop automated testing programs and control multiple WECG400 to test more than 4 DUTs simultaneously
  • Supports sequential testing - tests DUTs one at a time according to a user-defined sequence
  • Equipped with 4 DUT Monitor ports to connect to an oscilloscope - amplifies the ECG signals to help users monitor the signal output with higher resolutions
  • Rack-mountable and easy to deploy with the 1U height design

*Note: For the two test items as system noise and common mode rejection, please refer to the CMRR 3.0+ Common Mode Rejection Ratio Tester for testing.
