Version 5.01 improves the accuracy and reliability of measurements
taken with CTC WS200 and WS300 Bluetooth sensors.

PLEASE NOTE - REPORTED VALUES HAVE CHANGED

- Measurements now use the sample rate each sensor reports for
itself rather than its nominal rate. Reported frequencies may
differ from earlier releases, typically by 2% to 4% depending on
the individual sensor. The new values are the correct ones.
- The maximum frequency (Fmax) shown in the PDF report for these
sensors has been corrected. It was previously too high.

If you compare measurements taken before and after this update, a
small shift in frequency is expected and is not a fault.

BLUETOOTH RELIABILITY

- A new, more robust Bluetooth connection handler that reconnects
more reliably and gives clearer device status when you use
several sensors across different locations
- Vibration Pro now checks that every packet of measurement data
sent by a sensor actually arrived, and warns you if any are
missing rather than showing an incomplete measurement as though
it were complete
- Faults reported by a sensor are now shown to you together with
the remedy, and a measurement that stops part way through is
ended with an explanation instead of waiting indefinitely
- A Bluetooth measurement can no longer be cancelled once the
sensor has started taking data, because interrupting one corrupts
the measurement. With Auto Repeat on, Cancel still stops the
sequence after the current measurement finishes.

ALSO IN THIS RELEASE

- Fixed a scripting problem where special characters in a script
could prevent the script file from being saved in the output
directory
- A new Troubleshooting section in the built-in Help
- Apple Watch reliability improvements
- Bug fixes and stability improvements

Version 5.00 is our biggest update ever — a complete visual redesign of Vibration Pro.

- All-new, modern interface — clean, uncluttered screens for every channel and setting
- Color-coded channels throughout, so it's always clear which trace is which
- Drag-cursor readout — touch and drag on any plot to read exact values, with magnetic snap to peaks, in portrait or landscape
- Brand-new PDF report — crisp, professional, and identical on iPhone and iPad, with time series and frequency plots, acquisition and sensor details, and a full peaks table
- Redesigned peaks list, data source, and Machine Menu screens
- Refreshed app icon and launch experience

Under the hood, everything you rely on is still here: external Digiducer and Modal Shop sensors, CTC WS200/WS300 wireless accelerometers, full FFT analysis, scripting, and the Apple Watch companion app.
