Description

This module will plot the spectrum of the cross-relative phase between two vibration signals.

Compatibility

This module is compatible with the following sensors:

  1. TPI-9043

Main Menu

  1. Tap on the Sensor name button to open the list of available sensors, and select the sensor type from the list

    Note

    The user can change the order of the functionalities in the list by dragging it from the right button on each cell

Cross-Spectrum Phase Analysis

  1. The Start button will be disabled initially, until the sensor is connected.

  3. Click on the start ▶︎ button to take a reading. To zoom the plot use both fingers to pinch in and out, to pan use one finger and swipe left or right. Other options, such as windowing, filtering and cut-off value can be modified in the general Configuration view. See Configuration for more details.

  4. The settings pop-up will allow the user to change the spectrum type to Acceleration in G's, Acceleration in dB and Velocity in ips or mm/s. The sampling rate and the number of samples can also be changed here; options will depend on the available sampling rate and number of samples of each sensor.

  6. A full pdf report can be generated, saved or sent by clicking on the report button, see more info in: Generating a pdf Report.

Configuration

  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

  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.

    Note

    This selection will affect all reading's raw data for all modules

  4. 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.

Report

  1. The report view contains several options in the top bar menu: 1:Send by Email, 2:Save pdf locally, 3:Markup and 4: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 save 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.
