ABSTRACT:
A data processing system associated with a surface flatness measuring device, distinguishes between differential elevation signals respectively generated by an accelerometer type sensor while at rest and in motion. The readout of time-spaced data is thereby limited to those generated while the device is in steady state condition at rest in measuring positions, for collection of accurate data.
