This article describes the various ways that you can analyze collected data.

Annotating Data

Add annotations to the data you have collected.

Availability: Periodic Data mode

In Periodic Data mode, you can annotate a data set by adding comments or attaching files to it. You and other users can see this annotation when the data set is loaded in the Trend viewer.

Complete the following steps to add a comment or attachment to a data set:

  1. Click the Data Viewer (noloc_env_dataviewer.png) button.

  2. In the Trend viewer, double-click to place the cursor at the data set of interest.

  3. Click the Action menu (noloc_env_action.png) on the Trend viewer toolbar and select Add Comment.

  4. In the resulting dialog box, click the Add comment or Add attachment button to annotate the data set.

Changing the Time Range of Trends

In Periodic Data mode, the Trend viewer has a time-range property that controls the length of trends you load. Even if more data is available on the InsightCM Server, the Trend viewer displays only data from the configured time range.

In Stream Data mode, the time range is restricted to the duration of the stream you load. If you change the time range of the Trend viewer, the following viewers update to match the new Trend viewer time range:

  • Bode

  • Polar

  • Shaft centerline

  • Waterfall

Complete the following steps to change the time range for which you want to view data.

  1. Click the Data Viewer (noloc_env_dataviewer.png) button.

  2. Click the Set time range (noloc_env_time_range.png) button on the Trend viewer toolbar

  3. Select or set a date and time range.

Compensating for Slow-Roll Data

Enable compensation for slow-roll data when viewing your data.

Vector Compensation - When you configure sensors, InsightCM provides 1x Magnitude Reference and 1x Phase Reference properties that specify the magnitude and phase values when the shaft is at slow-roll speed. The Data Viewer page uses these properties to compensate for slow-roll in Bode and Polar viewers. If the configured reference values are incorrect, or you want to temporarily override them with different values, you can compute and apply new slow-roll references within the Data Viewer page. Complete the following steps to change the configured magnitude and phase references.

  1. Click the Data Viewer (noloc_env_dataviewer.png) button.

  2. Click the Layout (noloc_env_layout.png) button on one of the viewers, navigate to Chart type > Vibration, and select Bode or Polar.

  3. Click the Slow-Roll Override button on the Bode or Polar viewer toolbar to open the Set Slow-Roll Override dialog.

  4. Complete one of the following steps.

    1. Modify the values in the Magnitude and Phase columns.

    2. Click Cursor Values to set the override values to the magnitude and phase feature values. In the Bode and Polar viewers, you must place the cursor at a point on the chart in order to enable Cursor Values.

    Waveform Compensation - To distinguish between data that indicates a physical imperfection in equipment, such as a scratch on a shaft, and pure vibration data, the web application applies waveform compensation for slow-roll data. When the Order Waveform or Order Spectrum viewer displays a data set, the web application subtracts slow-roll data from that data set.

    Complete the following steps to enable slow-roll compensation.

  5. On the Order Waveform or Spectrum Order viewer, click Settings > Viewer Settings > Perform slow-roll compensation.

Compensating for DC Gap Offset

Change the configured gap reference for the Orbit or Shaft Centerline viewers.

  1. Click the Data Viewer (noloc_env_dataviewer.png) button to navigate to the Data Viewer page.

  2. Select the Layout button for one of the bottom row charts and navigate to Chart Type » Vibration » Orbit or Shaft Centerline.

    This will change the chart type and the corresponding toolbar buttons.

  3. Expand a Displacement sensor and select a feature that has calculated data to activate the chart's toolbar options.

  4. Click the Gap Override button on the chart toolbar.

  5. In the resulting Set Gap Override dialog box, complete one of the following steps.

    • Modify the values in the Override Value column.

    • Set the override value to the corresponding gap feature value at that timestamp by clicking the Gap Values button. In the Shaft Centerline viewer, you must place the cursor at Gap Values .

    • Restore the configured gap reference value by click Configured Values in the Set Gap Override.

Analyzing Unusual Data Events

Configure your data dissection options and dissect a data event:

  1. Select the Navigation menu (noloc_env_navmenu.png) and select Options.

  2. In the Options dialog box, navigate to Data Viewer » Data Event Dissection.

  3. Use the Data Event Dissection options to specify how to divide data events. You can divide data events into static block-lengths, a number of equal-length blocks, or into blocks of progressively shorter lengths. The Progressive data dissection option splits the last five seconds of the waveform into 200 ms sections, the previous five seconds into 0.5 second sections, and the rest of the waveform into one second sections.

  4. In the Trend viewer on the Data Viewer page, double-click the data event you want to dissect.

  5. In the Action menu (noloc_env_action.png) on the Trend viewer toolbar, select Dissect Data Event.

    When you dissect a data event in the Trend viewer, you can use any of the other available viewers to investigate the values of any of the features in your asset tree at the time of the data event.

Integrating or Differentiating Data

Apply single or double integration or differentiation to acceleration, displacement, and velocity data from your viewer.

Only the Orbit, Spectrum, Waterfall, and Waveform viewers support integration and differentiation.

  1. Click the Integration (noloc_env_integration.png) button on the viewer toolbar.

  2. Select an option on the dialog box and set the cutoff for the integrations you want to perform.

  3. Click OK and the viewer will update to show the integrated or differentiated measurements.

Correlations of Data to Speed and Events

Correlating Data to Speed

The Data Viewer page always displays the speed value from a sensor's speed reference in the metadata pane. The speed reference can be a tachometer, a fixed, user-defined speed, or a data source - such as, OPC UA or Modbus.


To view the metadata pane, click the Layout menu on the Data Viewer page toolbar and select Show Metadata .

Correlating Data to Events

You can annotate data to document the cause of a fault, or you can add comments to record information about a particular data set. InsightCM Server stores annotations with the data they apply to, and you can view annotations for a trend plot by clicking the Annotate Comments button on the Trend viewer toolbar.

The following metadata pane shows the information displayed when you analyze displacement data from a run-up stream. Notice the value of the speed reference at the time of acquisition.
