Parameter Values Comments
Signal Source Select from:
• Mid-Filter
• Post-Filter
•Alternate Path
Select the signal source for TWF and the FFT. (See Filters for a description of the various stages of signal processing where
you can get the processed data.)
Signal Source selections for FFTs (FFT Page) and Demand data (Demand Page), for the same channel, cannot be set to
different primary path sources:
• Both can be set to the same source, or…
• One must be set to Alternate Path
Measurement Select from:
• inch/s
•m/s
• mm/s
Select the engineering units for the TWF and FFT.
• The rules for units selection, which are based on the transducer units (the HW Configuration properties page), are
provided in this table.
•For any acceleration, velocity or displacement (length) units, the module can convert the measurement between
equivalent Metric and English units.
Speed Reference Select from:
•Off
•Speed 0
•Speed 1
• Factored Speed 0
• Factored Speed 1
Select the reference speed source.
When TWFs and FFTs are read from the module, the value of this RPM is included with the data.
