This module will plot a waterfall of vibration spectra. Each plot can be triggered manually or the waterfall plot can run continuously, to compare different spectra in the same plot.


This module is compatible with the following sensors:

  1. SensorWorks BluVib P-V-T
  2. SensorWorks BluVib M-V-T-3
  3. EI-WiSER™3X
  4. Digiducer
  5. Digital ICP Signal Conditiones
  6. EI-Wiser™

Main Menu

  1. Tap on the Sensor name button to open the list of available sensors, and select the sensor type from the list
  2. Select the Waterfall Plot option from the list.
  3. Note: The user can change the order of the functionalities in the list by dragging it from the right button on each cell

Waterfall Plot

  1. For wired sensors, connect the sensor to the tablet. For the wireless sensor connect to the sensor or select from the list of available sensors. Once the sensor is connected the start ▶︎ button will be enabled.
  2. From the settings pop-up select teh sampling settings and the type of spectrum. Set "Continuous Monitoring" to OFF to trigger each measurement manually or ON to automatically plot the data at the same time it is acquired. Other options, such as windowing, filtering and cut-off value can be modified in the general Configuration view. See Configuration for more details.
  3. Click on the start ▶︎ button to take the first reading. The module will plot one reading in single-mode, if the continuous mode is On, new spectra will be add to the plot sequentially.
  4. To zoom the plot use both fingers to pinch in and out, to rotate the 3D graph use one finger and swipe left or right.
  5. A full pdf report can be generated, saved or sent by clicking on the report button, see more info in: Generating a pdf Report.


  1. From the Main menu, click the top left menu button to open the left drawer with more options. Select 'Configuration' from the left menu
  2. Select the Plot Thickness, Cursor Thickness and/or Cursor Line Type from the Plot Settings selectors.
  3. The Signal Settings will affect the raw data directly. The DC-Removal is ON by default by can be turned OFF here. Also a general Low-Pass or High_pass filter can be applied to the signal.
  4. Note: This selection will affect all reading's raw data for all modules

  5. The FFT Settings will be set as defaults for all readings. Here the user can change the spectrum frequency units to Hz, CPM or Orders. A Cut-Off value can be added to remove low frequency values. Also windowing can be selected for the spectrum, the available options are: None, Hanning, Hamming, Blackman, Nutall and Flat-Top. The spectrum type and RMS/Pk values can be set as defaults here, but can also be changed in the settings pop-up of the spectrum.


  1. The report view contains several options in the top bar menu: 1:Send by Email, 2:Save pdf locally, 3:Upload Report to the Cloud bucket, 4:Markup and 5:Report Configuration
  2. The markup tool allows the user to copy the report to the clipboard, send it by Airdrop or any other messaging app, email it, print it or saved it to Files. The markup tool will open the standard tool to paint on the pdf report.
  3. The Report Configuration pop-up allows the user to enter the Report Title, Machine ID and Notes to be added to the report. Here the user can also select a logo for the report and include a picture of the asset that will be added in a new page in the report. The report file name be default is the actual date and time, but the user can change it to the title name of the report or to both, the title name and date.
