WECG400 ECG performance tester USING production line

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.
