Software Test Drive

The Model DL-1 instrument is a highly accurate recording instrument, but its greatest feature is the TRAC4 Software program. The software is what allows the user to interact with the instrument and is the principle means for sharing the information collected by the DL-1 with others.

The TRAC4 software is not only included with all Model DL-1 data loggers, but is also available for download at no charge to anyone. This allows DL-1 users to share data with colleagues and clients, within the native TRAC4 program, which protects the collected data, as changes are not permitted.

This also means that anyone can take a test drive of the TRAC4 software prior to purchasing a DL-1 data logger.

The first step is to download and install TRAC4:

My DL-1 received a battery upgrade and now I cannot connect to TRAC4
During the repair and upgrade process, your DL-1 unit was given a firmware upgrade. This requires the latest version of TRAC4. Click here to download and install

Will TRAC4 work on Windows 8, 8.1 or 10?
Yes, but as with Windows 7, the user must have certain Administrative rights for full functionality.

After installation, TRAC4 doesn't recognize the DL-1 is connected. I rebooted and still not recognized. What now?
The USB drivers may not be installed on your system. This sometimes happens with Windows XP. The USB drivers can be downloaded from the Software Download page.

Does the new software work with the older DL-1?
No, the new TRAC4 software works only with the latest version of the DL-1 hardware.

How do I tell if I have the new DL-1 or the older DL-1?
The easiest way to determine if you have the newest (2011) version of the DL-1 or an older version is to determine the shape of the DL-1 case. The older versions have one flat side and then a rounded side. the latest versions (2011) have four flat sides. there is a picture of both on the Software Download page.

Does the TRAC4 software run on Windows 7 and Vista?
Yes. However, the TRAC4 program requires some Administrative rights on Windows 7.
