Contents of Archive:
===================
The archive Setup_L965_XXX.zip contains all needed files for installation plus the readme.txt (XXX denotes the Release). After installation you'll find the following files besides others:

 - Setup_L965_XXX.exe	installer
 - readme.txt     	this text
 - BMT965_default.cfg	default configuration settings file

The installer is also available on the SD card of your analyser in the folder \Setup_965Link\
The application is installed as a removable installation on the SD card of each BMT 965 under \Run_965Link\


Purpose:
========
This software program is solely designed to work with BMT 965 Ozone Analyzers using the USB port. It will not work together with the predecessor BMT 964. Minimum requirement is a BMT 965 series instrument, a PC running Windows XP/Vista/7/8/10/11 (32bit) and at least one free USB port at the PC.


Installation:
=============
Please note the Software License Agreement (License.txt) before installing and using the Software.

To permanently install the software, unpack the ZIP archive into a temporary directory of your choice, and run the installer Setup_L965_XXX.exe , which will install the executable and help files to the appropriate folders. Duting installation, you may choose to install the software as Portable Installation on any drive accessible from your PC.

Such a portable installation is already installed on each BMT 965 on the SD card in the folder \Run_965Link\ , ready to be run from there.


Running the Program:
====================
Connect your analyser to the Computer using a USB cable (supplied with the analyser). If it is connected the first time, the appropriate HID driver will be installed by your Windows. Once this is finished, running the BMT 965 Link will retrieve data from your analyser.

A list of command line parameters is found in the Help file. 

This software does not contain a software manual. Please refer to the Help File (press F1 within the software, or open L965.chm manually) for further information on how to install and use the program. A copy of the analyser's manual is found on the BMT 965 itself, if you connect it to the computer (acts as logical drive).
