The utilities embedded on the Model 336 are written using the Java™ programming
language. This theoretically allows the applications to run properly on many different
platforms (Windows®, Mac®, Linux™, etc.), although the applications are only sup-
ported on Microsoft Windows® XP or Windows 7 and Vista®, and have been designed
to work with the Java™ Runtime Environment (JRE) version 1.6. To download Java ™
JRE please visit www.java.com.
Please note that without the proper JRE installed the utilities will not run properly.
The applications are launched from the Utilities web page using Java™ Web Start
technology. This allows the application to run outside of the web browser in a stand-
alone window. The application can only be launched using the link in the embedded
web page, and cannot be permanently installed. When launching the application,
multiple security warning messages may appear. These messages are meant to pro-
tect youfrom malicious software that can cause harm to, or compromise the security
of, your computer or your data. The applications have been thoroughly tested and are
considered by Lake Shore to be safe.
All software is imperfect and any software may be used by a malicious user for malicious
purposes.

files to the Model 336. The utility is also capable of reading curves from the

curve files in the ".340" file format, and the Microsoft Excel® ".XLS" (Excel® 97 - 2003)
