Dears,
Bently Nevada Probes having Supply of -24VDC Supply because of NPN Transister used, so Sensor has to work between 0 to -24 VDC Range.
if u see the Graph of it's Vibration charesteristics it will be Linear Between -2 VDC to -22 VDC range & Vibration belongs towards &/or away from the probe.
and we can't say Vibration of M/C will be in which direction happens.
So it is Better to select middle point of it's Range as we can't assume Vibration Direction.
That's y Average/Middle point of Linear Graph range(-2 VDC to -22VDC) is -10 VDC(to Give Justice to Probe.
That's the reason of -10VDC Gap Setting needed.
Dear's this is the Answer according to my Knowledge.

Thanks in Advance.
