Res
Resistance of geophone coil in Ω (Rc).
Freq
Natural frequency of coil (Fn or sometimes F
0
) in Hz.
Sens
Sensitivity of coil in V/m/s (G).
Damp
Damping of coil (B
0
).
Dist
Distortion limit in %.
Fdis
Frequency at which distortion will be tested in Hz.
Mexc
Moving mass excursion in m.
Mass
Moving mass in g.
Temp
