If you collected data on the measurement point, Low Frequency Analysis - Slow Speed
Technology (SST) uses the original acquisition settings. If you mark a low frequency peak in
the spectrum before running this test, Low Frequency Analysis - Slow Speed Technology (SST)
uses that frequency and sets the new Fmax equal to or just above the marked frequency.
Prerequisites
A special, low frequency accelerometer is recommended, but SST also works with a
standard sensor.
Procedure
1.
Create a job or open Analyze from a route measurement point.
2. From the Analyze main menu, press F10 Low Frequency Analysis - SST.
If you disabled the help text, data collection begins.
3. Press Start or Enter to collect the data.
4. Press Enter to view the data.
One or more plots display after the data is collected.
5. Press F9 Store Data to save the data to a route or a job, or press F8 Start to redo the
measurement.
6.8.7 Turning Speed Detection
Turning Speed Detection confirms the shaft-turning speed frequency based on an estimated
speed. The dominant peak nearest the suspected turning speed frequency is most likely
the turning speed. Turning Speed Detection is available when you collect data on a variable
speed machine.
Prerequisites
Set up your sensor.
Procedure
1. Create a job or open Analyze from a route measurement point.
2. From the Analyze main menu, press F11 Turning Speed Detection.
3. Press Start or Enter to collect the data.
4. Enter an estimated machine speed.
5. Press Enter.
6. Press Enter to view the data.
One or more plots display the collected data. The analyzer displays the detected
speed at the bottom of the screen.
Note
You cannot store this data.
