The accelerometers on MTS400 board are not individually calibrated. In order to get more accurate acceleration reading, you will need to estimate the bias and sensitivity by orienting each accelerometer axis towards the gravity axis (+1g and -1g) and then use those calibration constants in the xlisten parser/converter.
