5. Insert the end of the probe into the area to be sampled.
6. Squeeze and release the aspirator bulb 15 times.
Monitor the readings and note if any alarms occur. The readings will peak shortly after the
last squeeze and may decrease before all the channels can be checked. To see the
maximum readings for each channel, display the peak readings for each channel in
Display Mode (see “Display Mode” on page 23).
NOTE:
The peak readings for each channel are saved until a higher peak is recorded, the
peak readings are reset, or the instrument is turned off. If a gas is present but the
level does not exceed the previous peak level, the previous peak will be displayed on
the Peak Reading Screen.
Data Logging
The GX-2009 features the ability to log data to its internal memory and download it to a
computer via the infrared communications port on the top left side. It logs gas readings during
normal operation, alarm data, calibration data, and bump test data.
To utilize the GX-2009’s downloading capability, you will need the GX-2009 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-
2009. 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-2009 using the USB port. The GX-

description of the GX-2009 Data Logging Management Program and procedures for
downloading data to a computer.
GX-2009 User Setup Program
There are some instrument operating parameters that are not accessible in either Calibration
Mode or User Setup Mode such as the calibration frequency, auto zero function, and the alarm
logic (latching or self resetting). Many of these parameters either do not typically need to be
accessed once the GX-2009 is shipped from the factory or may only need to be accessed once
because of operator preferences. These parameters can be accessed and updated if necessary
using the GX-2009 User Setup Program, a computer with the same requirements described
above in “Data Logging”, and a USB/IrDA cable if necessary. The GX-2009 User Setup
See the GX-2009 User Setup Program Operator’s Manual for a complete description of the
GX-2009 User Setup Program and procedures for accessing and updating instrument
operating parameters.
