Other Parts Discussed in Thread: ADS1198

Dear All,

                       The ADS1198ECG-FE has configured to detect leadoff. But I am not able to see a propper ECG signal on the display screen. I am seen only Noise on the display screen, lead off. Please reply me ASAP to fix this issue.

Thanks in advance,

Regards,

Bhairu

    Hello Bhairu, 

    I would suggest simplifying your configuration until we find the source of the problem.

    First, I would disable lead-off detection for now. With the default jumper settings, see if you can acquire data with the internal test signal.

    If that works, restore the channels to Normal Electrode inputs and use a waveform generator to input a 100 mV sine wave into the device. Make sure the DC level of the signal is within the input common-mode range of the ADS1198.

    Let me know how you progress. :)

    Best Regards,
