Answer / aftab ahmed mazari

First you know which type of vibration probe you using.
Suppose you using proximity probe. Then check followings:
1. Its resistance, usually Bently Nevada common probes
restance varies from 4.5 ohm to 6 ohms. But if you using
asnother company probe, then see its literature.
2. Also make a graph of vlotage vesus distance of probe,
its behaviour should be linear.
3. If you have vibulator(Vibration source), then check it
with diffewrent vibrations.
