How can I calculate the sensitivity of a seismometer? I would like to know if a specific seismometer can measure 1 micron/sec velocity. I have a few specs from the datasheet but I'm not a seismologist and am trying to figure out how to relate the specs to one another.

I have:

Velocity output band: 30s (0.03Hz) to 100 Hz
Output Sensitivity: 2400 V/m/s
Peak/Full scale output: Differential: +- 20V 
Sensor dynamic range: 137 dB @ 5 Hz


Thanks in advance!
create a bench test using an acceleramentor and a transducer since their values are known then equate the results to your sesimo
