Chapter 5 Collecting and Reviewing Data
Create a User-defined Point
Follow these steps to create a user-defined point.
1. Select Data Collection from the Main Menu and press the Enter key.
The Data Collection screen appears.
2. Select the route and press Enter.
The Dynamix 2500 data collector always associates Offroute
measurements with a list.
3. Press F2 (Offroute) to collect an Offroute measurement.
High Res. The measurement configuration is based upon the most recently selected
measurement in the Route Manager
The setup is identical to the active measurement in the active Route, except the
Lines/Samples setting is doubled (increased by a factor of 2) to a maximum of
25,600 lines (up to 12,800 for two-channel measurements and up to 6,400 for three
and four-channel measurements).
For example, if the active Route Point’s Lines/Samples setting is 400 Lines, the
High Resolution Offroute measurement’s Lines/Samples setting is 800 Lines.
This lets you take a high resolution look at your active Route measurement.
Measurement parameters are set to:
Overlap – 50%
Bin Zeroing – On
gSE Performs a standard vibration Acceleration measurement and collects waveform
data.
These are the settings for the measurement parameters.
Orbit Measures the path of a shaft center-line motion during rotation. Parameters for
Offroute orbit measurements are configured in the Offroute Orbit Setup screen.
