[1] Connector mates with Dytran cable assy. Model 6811Axx. (xx = length in feet)
[2] Reference sensitivity measured at 100 Hz, 1 g rms per ISA RP 37.2
[3] Linearity is % of specified full scale (or any lesser full scale range), zero-based best-fit straight-line method.
[4] Power only with Dytran LIVM power unit or other Dytran-compatible constant current type power unit. If power
is applied without current limiting protection, the internal amplifier will be immediately destroyed.
