ADS1292R: Does ADS1292R must calibrate?

Hi Ariel,

Thank you for your post.

Can you please clarify what the output value plot in your attachment is?  I am not sure what you are asking for in terms of calibration.

Thanks.

Hi! TCT：

This is our ECG data. X-Axis is ms. 80% main board's data just like this plot. Less 5% Y-Axis data would shift. The shift value is random. In our manufacturing process, we did not calibrate this sensor. Do we need to do calibration?

Hi Ariel,

The ADS1292R does not need any calibration to acquire the ECG signal. It doesn't look like you are getting the correct ECG signal from the hardware. I recommend using an ECG patient simulator to test your hardware or use the internal test signal function to ensure that the signal chain is working correctly.  

Thanks

Hi! TCT：

Thanks your reply！ This plot is using ECG patient simulator to send 2Hz sin wave.

There are 2 failed plot.

Plot_1 is total signal shift.

Plot_2 is signal distortion.

For now our engineer replaced the capacitance at Vref or replace ADS1292R to solve those 2 issue.
