Accelerometer raw data output to measure vibration,and do a frequency spectrum/ amplitude spectrum?
If it's anything like my old washing machine, 100 data values collected over 100 seconds isn't worth the paper you might print it on. Nyquist "says" the highest frequency you can extract (based on 1Hz sampling) will be 0.5Hz and for sure, when the machine is spinning, it's going to be several Hz and this will produce aliasing in your sampled results rendering them near-useless.
