-Health Wearables Testing
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
- 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.
