Today we have updated the latest version of MultiTool to 4.5.12.

This release brings new features to the acquisition system with an option to use automatic thresholds determined by the acquisition hardware. See the acquisition manual for more details.

A fix has been put in place for flight hardware from Rotadata.

Alarms have been added for laser temperatures.

The probe positioning algorithm has been refined to help determine the best positions in fewer passes of the calculation.

A fix has been put in place for a rare stack crash with bad data and no stack being displayed when the number of blades is very small.

Various bug fixes.

2nd March 2025

Today we have released version 4.5 of MultiTool.

This release brings new features to support the next version of the Acquisition hardware. We can now support Inductive probes as well as optical probes.The probe type is now selectable from the editor. The default probe type is optical.

The new acquisition hardware also has automatic threshold implemented in hardware. We have tried several conditioning schemes over the last few years and chosen this approach as the most reliable for the applications we have been involved in. The conditioning type can also be selected in the Editor on a per probe basis. The default is Manual.

We have made some changes to allow interoperation with some partner devices.

As this is a point release anyone with a V4 license can update to this version free of charge.

Further bug fixes and enhancements.

Today we have released version 4 of MultiTool.

This release brings new features in the Acquisition for generating a Once Per Rev signal from the probe signals with both hardware and software solutions. We still recommend a physical OPR but these new features provide options where either fitting an OPR is not possible or the existing one has failed. We also have the ability to generate an OPR after the test from the recorded probe data. There is a YouTube video covering this functionality so please check it out. If you have an update subscription then download the software here.

We have added the ability to calculate the best axial position for the probes into the Editor. If you have a design sublicense for probe placement then this is included for free. The file format for the mode shape data is published in the Editor manual and a demo file is available in the downloads section.  There is a YouTube video covering this new functionality so please check it out.

Bug fixes and enhancements.

YouTube Channel Update

We have also released some tutorial videos onto our YouTube Channel. Due to the current situation we will not be travelling for training sessions so the aim is to cover the basic operation of the software, pointing out features and functionality that even existing users may have missed. Feel free to head over and take a look.

Update – The demo files used in the videos are available from the downloads section.

Be safe.
