T.S.F = Transducer Scale Factor. To use the formulas, the T.S.F. should be in
volts and the T.S.F. and full-scale values should both be of the same unit
system (metric or English). The transducer Scale Factor will always be
specified as volts per g pk or volts per m/s
2
pk.
Example 1:
Transducer Scale Factor = 100 mV/g
Full Scale = 2 g peak
For Peak to Peak input:
