What is the model of the accelerometer?
Also, would you please out the values directly read from the accelerometer, as soon as it’s read.

Something Ike:

Serial.print("xRead = “);
Serial.print(xRead);
Serial.print(”, yRead = “);
Serial.print(yRead);
Serial.print(”, zRead = ");
Serial.println(zRead);

I can’t think of anything to ask other than to check that this is actually an analog output sensor rather than an I2C sensor.

All of my IMUs are serial devices of some kind (I2c or SPI).

I hope this helps.
