Vibration Historical

The Vibration Historic dashboard shows a historic view of all vibration spectra that were measured within a specified time.

All spectra within the specified time range of one device are shown in a 3D plot on the Vibration Historic dashboard. The Device and Data Type (acceleration/velocity) can be selected at the bottom of the page, as shown below. Specific data can be selected in the list at the bottom. The resolution of the frequency axis can be changed by specifying the RPM grid delta. Clicking the Refresh button reset the RPM grid delta to its minimum of 6000 RPM (1000 Hz). The In CPM toggle switches the frequency axis units between Hz and Counts Per Minute.

Figure 7: Select data for the vibration historic plot

The graph in the middle of the page shows all selected frequency spectra within a specified time range. It has three axes: Amplitude, frequency (or cpm) and time. To specify the time range from which to show data, click the designated button at the top right of the page (this can read Realtime or History).

This will open the options screen as shown below. Make sure the History tab is selected. Specify what data to show using:

1. Last: Specify how far back historic data should be specified. Defaults to 7 days, but can be increased up to 30 days. Use the advanced option to specify how many days, hours, minutes and seconds exactly.

2. Time period: Specify the period of time from which data should be shown by selecting a start and end date time.

3. Interval: Select the interval of time from which data should be shown, i.e. current day or current hour.

4. Data aggregation function: Aggregate data over the Grouping interval and specify how to handle the result. Of the aggregated data the minimum, maximum, average, sum and count can be shown. Choose None to disable the data aggregation function.

5. Timezone: Specify the timezone to base the options upon.
