Dear Valued customers,

We have recently found problems with the sound and vibration analysis system O-Solution.
We sincerely apologize for any inconvenience caused.
We would like to inform you about the cause of this incident, counter measurement, and prevention of recurrence as follows.

 

Affected product

Product name	：Sound and Vibration Analysis System O-Solution
Version	：Ver.1.4.10 or later

 

Details of bug

We found a bug where incorrect X-axis values were saved when exporting a CSV file from the graph window after converting the X-axis unit to arbitrary unit in the schedule diagram of the rotation tracking analysis. Although the data is displayed correctly in the O-Solution screen, the X-axis values in the exported CSV file are incorrect. *There is no problem with the analysis data (DATX file).

●Bug 1: The set conversion factor is applied twice.
●Occurrence condition 1: Export a CSV file from the Graph window with the following settings:

Analysis function		Tracking method	Graph type
Analysis mode	FFT tracking analysis	Rotation	Trend
	Octave tracking analysis	Rotation	Trend

●Bug 2: The set conversion factor can not be applied.
●Occurrence condition 2: Export a CSV file from the Graph window with the following settings:

Analysis function		Tracking method	Graph type
Measurement mode	FFT tracking analysis	Rotation	3D
	Octave tracking analysis	Rotation	3D

Ex) Conversion from rotation speed [r/min] to vehicle speed [km/h] (Conversion factor: 0.017)

1. Check the Setting any unit on the schedule diagram and set the conversion factor

2. Exporting a CSV file from a graph window.

In addition, we have also fixed the newly found bugs in response to this issue. For details, please refer to the attached version upgrade history.

Causes

The data processing of X-axis values when exporting CSV files was not unified, and the timing of applying the conversion factor differed between graph drawing processing and CSV export processing. As for the other bugs, it was caused by processing that did not consider the exception handling.

 

Counter measurement

The software has been fixed and updated.
Please download the revised software from our website.


●Version：　         Ver.5.0.5
●Release date：　8 April 2025
Please export the CSV file again after you downloaded the revised software.
