been designed for Windows XP/Vista/7/8 & 10. For installation of the program, simply unzip the
ZIP archive if necessary, and execute the Installer 'setup.exe', then follow the descriptions on
screen. See the file readme.txt on the SD card for further information.
For connection with to a computer, a USB cable with a length of 2 m is provided with each ana-
lyser. A normal USB cable of a maximum length of 10 m may be used.
Among other features, the software application allows:
simple configuration of all parameters of the BMT 965. With a few mouse clicks you can view
respectively change e.g. the units of ozone concentration and pressure, alarm parameters, prop-
erties of the serial interface in User-Mode, characteristics of the carrier gas, date and time and
other parameters (serial number, operating hours etc.)
storing of all modifiable characteristics in files. In order to configure several instruments with
the same set of parameters, only the corresponding file has to be loaded.
downloading and viewing concentration logfiles of selectable measurement results or parame-
ters (e.g., cuvette dirtiness)
create Diagnostics Reports: view and printout all internal system data (e.g., raw data from the
A/D-converter, operating hours)
The main screen shows the basic measurement of the ozone concentration, the pressure measured
internally for compensation and cuvette status. From the View menu, you may choose the Param-
eter window, which shows all custom settings of parameters that may be changed, sorted in tabs
named the same as in the front panel menu. As a start, you should check the units used by the
analyser, and set the time (built-in real-time clock of the BMT 965) according to the local time in
your area. This is the time used in the Error- and Event Log.
Also, in the main menu, you'll find a Monitor window, designed to be enlarged so that you may
view the measurements from some distance, and a Diagnostics window, summarizing all raw data
mainly needed for troubleshooting by BMT. Other than that, the Error- and Event Log may be
loaded from the instrument to the screen via the View menu.
The options in the main menu let you set your preferences concerning the software behaviour
itself. For example, you would choose "Print to file" if you are on site with no printer available.
On some screens, you'll find a print function for two different printouts, one summarizing the
settings and measurement for documentation, one including internal voltages and values for trou-
bleshooting by BMT. Both should be emailed to us in case of problems. The printouts include
both the Error- and Event Log.
The Save and Load functions in the main menu under File are used to save configurations of the
BMT 965 onto your PC and load it again at a later time. This helps configuring all analysers with
identical settings in multiple locations of one project.
For a more detailed description of the software, please refer to the helpfile (bmt965.chm, to be
opened with F1 within the program or a double click in the Windows Explorer).
