Lsm6ds3: I'm working on Fifo functionality of Lsm6ds3 for z-axis but when i retrieve values I'm getting higher g values of 2g at steady state. Can somebody explain why such higher values are generated.

I'm using FIFO in continuous mode and when i read from LSM6DS3_ACC_GYRO_FIFO_DATA_OUT_H register most of the times I'm getting constant value of 0x0F from this register at steady state. The values generated at steady state are 2g always.
