Overview of the Data Logging
Software
The Model GX-2001 is a gas monitoring device for combustible gases, O
2
,
CO, and H
2
S. It measures combustible gases as a percentage of the lower
explosive limit (% LEL), O
2
as a straight percentage (%), and H
2
S and CO
as parts per million (ppm). The Model GX-2001 also records STEL and
TWA readings for H
2
S and CO.
STEL is an acronym for short-term exposure limit, and it shows the average
reading for H
2
S and CO during the last 15 minutes. TWA is an acronym for
time-weighted average, and it shows the average reading for H
2
S and CO
during the last eight (8) hours.
This, and other information (e.g., calibration history), is recorded by the
Model GX-2001 and is stored in the unit’s on-board memory. The GX-2001
Data Logging/Charger Station and Software down loads this information to
your computer for viewing, printing, and saving.
Types of Information Provided
The Data Logging Software provides information about gas concentrations,
alarm trends, calibration history, and instrument data. This section of the
manual has sample data screens along with a “road map” of the Data
Logging software to help you become better acquainted with how the Data
Logging Software works.
