Trying to use this with Geophone SM-24 #9

I am trying to use the ADS1220 with the Geophone SM-24, originally as part of this tutorial: https://create.arduino.cc/projecthub/team-protocentral/measuring-seismic-activity-using-protocentral-openpressure-702324

Here is the link of a signal I get when I wire it up: https://i.imgur.com/hNdHcuM.png Do you know what the issue could be? It seems squarish, with lots of 0 values.

The ADC seems to saturate when pick up and shake the geophone gently. Is this normal? Anyone know what could be causing this?

I was had the same problem. I added two resistors the problem was solved. It doesn’t matter if the sensor is a thermocouple or a geophone.

Interestingly, did you find a solution? I spent a few days on it.
