Default
Gap
DC sensor Gap voltage for diagnostics.
Default
1X amplitude
and phase
A synchronous amplitude and phase measurement at
running speed.
Default
Requires PT
2X amplitude
and phase
A synchronous amplitude and phase measurement at twice
running speed.
Default
Requires PT
nX
An additional synchronous amplitude and phase
measurement at the configured multiple of running speed.

Default
Requires PT
Band-pass 1
An additional Peak-Peak bandpass filtered measurement.
Add this band-pass filter to filter a different region, change
units or subunits, or provide additional alarms.
Add (if needed)
Band-pass 2
An additional Peak-Peak bandpass filtered measurement.
Add this band-pass filter to filter a different region, change
units or subunits, or provide additional alarms.
Add (if needed)
