Pocket VibrA
Vibration Analysis Specifications
FreeTrend software functionality:
Asset manager:
- Displays asset status (valid, warning or alarm) for ISO
- mm/s and bearing quality with date and time of reading.
- Assets can be Created, Edited, Deleted, Copied and Pasted into Sites.
- Sites (and their assets) can be selectively added to a sync list for downloading to PocketVibrA unit.
- Routes can be automatically set up and down loaded.
- Reports can be created on individual or groups of assets (selected via the Report Wizard) and produce editable Word files with embedded Excel graphs for trends and frequency plots.
Measurement point display:
- Total vibration (mm/s and g), ISO mm/s
(10Hz-1kHz,Bearing Quality, VA Bands (instability, balance, misalignment and looseness) plus any number of user defined parameters (text or numerical values).
- Individual readings (on any date) can be selected for frequency plot or waveform display (all axes are zoomable). Top ten peaks can be displayed and sorted by frequency or amplitude.
PocketVibrA software functionality:
Asset manager:
- Displays sites, assets and measurement dates and times as a “tree” structure.
- Stylus free navigation of route and measurement points and capture of readings using keypad.
- Assets can be Created, Edited, Copied and Pasted into Sites (password protected on PocketVibrA).
- Single and continuous reading “meter” mode with continuous FFT display.
- Options to “run asset” (take new readings) or “continue asset” (add to previous readings).
- Auto identification of measurement points using barcodes or auto recognition of “smart” accelerometer via easy to use set up procedure.
“Run asset“ display:
- Individual measurement points (MP) are numbered and described with text.
- MPs are colour coded to show if a reading has been taken (red) or not yet taken (green).
- Previously taken readings can be viewed or retaken.
Measurement point readings display:
- User selectable simultaneous display of any four from: ISO mm/s, Total RMS (mm/s or g), Bearing quality, Peak (mm/s or g) or Crest Factor.
- Time waveform and frequency plots (zoomable axes).
- VA bands display as alarm colour coded RMS values.
