Part 6 – Data Logger (Option)
6.1
General
The data logger module is an entirely separate device from the Q45 and is supported by a
complete software suite for the PC. The required download cable and software are available as
an option (only one download cable and one piece of software is required to download an
unlimited number of modules.) The software also sets the recording interval, time stamps, and
scaling for the module. The module is removed from the analyzer when setting up or configuring
the settings. The logger module itself is a self-contained, battery powered device.
6.2
Removing the Data Logger
The data logger is held in place on the front panel with two screws. The logger clips onto the
screws and slides down about ¼”. To remove the logger, push it up slightly. You will feel it slide
on the retaining screws. After sliding it up, pull it toward you to disengage the screws. Reverse
the process to remount the logger.
6.3
Starting Logger
The data logging function is activated using a computer connected through a USB port. The
software package is called HOBOware Pro for Windows (a MAC version is also available). The
software and an instruction manual for the software are provided when ordered. The software
and the USB to Logger cable are provided in the foam insert behind the hinged panel of the
PQ45H.
Prior to operating the logger, the software must be installed on your computer. Insert the
software CD into your CD drive and follow the instructions on your computer screen for
installation. For convenience, you may wish to install a shortcut icon on your desktop for starting
up the HoboWare Pro software.
The manufacturer of the data logger and software provides a convenient on-line video instruction
for using HoboWare Pro software. From your internet command line, type in
http://www.onsetcomp.com/files/flash/software/HOBOware_Demo_Launch.swf. The demo lasts
for about 3 minutes and will give you good primer on setting up your logger.
The cable supplied with the software provides a USB connector on one end and a special
connector that plugs into the data logger on the other end. If you are using an older computer
equipped only with an RS-232 port, special RS-232 to USB cables are available commercially
that will allow you to adapt to the logger.
Your data logger will have an initial setup already programmed into it from the factory. This setup
is done in order to check the unit prior to shipment. You will need to change the channel scaling
to fit your specific requirements. The factory default for the logging interval is 1 minute, which
again can be easily changed to suit specific application requirements.
Consult the software manual supplied with the system for details on programming the logger,
activating the logging cycle, downloading the logged
data, and other aspects of data handling.
The HOBOware Pro software allows you to convert the data contained in the file to either Excel,
Lotus 123, or comma delimited text files for manipulation using other programs.
