1. A method of acquiring seismic data comprising:

  • sensing seismic energy with one or more sensor modules, wherein the one or more sensor modules comprise one or more force feedback controlled accelerometers;

    recording seismic data indicative of the seismic energy using a seismic recorder; and

    determining a state-of-health for the sensor module comprising;

    operating the accelerometer for a period of time; and

    analyzing an output signal generated by the accelerometer;

    wherein analyzing an output signal comprises detecting an excessive root-mean-square amplitude response of the output signal to indicate a malfunction of the accelerometer or a noisy environment.
