Data Logging
The GX-3R 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 stores data, how many channels
are active, and how often the GX-3R 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
three 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.
