Data Logging
The GX-3R Pro logs Measuring Mode gas readings, alarm data, and calibration data to its internal
memory. Logged data can be download it to a computer via the infrared communications port on
the front of the unit.
To utilize the GX-3R Pro’s downloading capability, you will need the GX-3R Data Logger
Management Program and a computer with an infrared port or a USB port that runs one of the
following operating systems: Windows 7, Windows 8, or Windows 10. If your computer has an
infrared port, then no additional accessories are needed to download data from the GX-3R Pro. If
your computer does not have an infrared port but does have a USB port, a USB/IrDA adapter
cable can be used to download data from the GX-3R Pro. The GX-3R Data Logger Management
Program is available at www.rkiinstruments.com/gx3rpro. The USB/IrDA adapter cable is
available from RKI Instruments, Inc.
The data logging capacity depends on how often the GX-3R Pro stores data, how many channels
are active, and how often the GX-3R Pro is turned on and off. The table below illustrates how
much data logging time is available for the various interval times. It assumes that the unit has four
sensors, is only turned on once, and there are no alarm occurrences. The data logging interval time
must be set using the GX-3R Data Logger Management Program.
For a complete description of the Data Logger Management Program and procedures for
downloading data to a computer, see the GX-3R Data Logger Management Program Operator’s
Manual.
