RV Option
The RV (raw vibration) option includes a 100mV/g ±20% additional output. The accelerometer frequency range is
1 Hz-1 kHz, maximum amplitude of 15 g-pk. Data collectors or analyzers can use this vibration signal for further
analysis. This output is extended to the RVVO (Raw Vibration Velocity Output) option, which integrates the signal
to a value of 100 mV/IPS (±20%).

Note:
-The RV and RVVO Signal Negative has to be isolated from any grounding. If this terminal is grounded, the 4-
20mA loop will short, causing no output.
-The RV and RVVO output signal is ideally suited for use with portable battery powered data collectors or
analyzers.
