What data does U-Tune use?
U-Tune can use data from either of the following sources:
Why are .WDQ waveform files not associated with any application?
Waveform files are produced by DATAQ data acquisition equipment (although they can also be created by U-Tune from text files) and are normally associated with their software. You can download a free waveform browser from http://www.dataq.com/products/software/playback.htm.

What differences are there between versions?
Version 2 includes the Manager which allows the results of up to 10 step or pulse tests to be stored. An average process model is computed from the stored records and used to calculate the most appropriate tuning parameters.
Version 2.1 fixed several issues in Version 2.0 mainly relating to opening a corrupted waveform file. It includes the new feature of writing the configuration file to a text file. The new version supports the same configuration file format as Version 2.0.
Version 2.1.1 included minor fixes:
1. A warning is given when trying to open a filename with a name over 128 characters. The restriction is due to Third Party software beyond the control of Contek.
2. U-Tune used to crash when changing the chart top or bottom limits with no trend loaded.
3. The integral parameter used to be limited to three digits. This has been increased to four to give better values for seconds/repeat.
4. An integrating system has been included with the example files to show how the pulse test is accomplished.
5. If U-Tune gives a run-time error 449 when opening a trend, you need a different version of the file DataqFile.ocx. Download it here and copy it to the Windows/System32 directory. This is not required for versions after 2.1.1.
Version 2.2.0 included the following changes:
1. Clicking on a configuration file (.TUN) will open up the U-Tune application.
2. The trend windows stop scrolling at the end of the trend data.
3. If you move a configuration file, it will look for associated trend files in the same directory as well as in a /Trend directory.
5. U-Tune loads much faster.
6. The method of purchasing from Kagi has changed. This means that if you've already bought 2.1.1 or an earlier version, you'll need to get a new key code by emailing me (email@example.com) your username and registration code so I can explain what you need to do. You will not need to pay a second time!
Known issues with Version 2
U-Tune will not open files if the full filename is too long (about 128 characters). Moving the file further up the directory structure or shortening the pathname will get around the problem. Version 2.1.1 now gives a warning message if the filename is too long.
Check the version of your copy of U-Tune on the <Help><About> window. The latest version is 2.2.0. If you've already purchased an earlier version, you'll need to email me (firstname.lastname@example.org) your username and registration code so I can explain how to upgrade to the latest version.
