WARNING: Understand this manual before using the GX-2001 Data

Logging Software. Also read and understand the Model
GX-2001 Operator’s Manual included with the Model GX­2001 portable gas detection unit.

Introduction

Using an advanced detection system consisting of four gas sensors, the
Model GX-2001 Personal Four-Gas Monitor detects the presence of
combustible gases, oxygen (O

sulfide (H
easy-to-use design makes it ideally suited for a wide r ange of applications,

as described in the Model GX-2001 Operator’s Manual, which you should
read first before using the GX-2001 Data Logging/Charger Station and
Software.

The Data Logging/Charger Station and Software (RKI part number 49­2156RK) down loads stored data in the Model GX-2001 to a Windows­based PC. After the data has been downloaded, you can view, save, or
print it using your computer and the Data Logging Software. The Data
Logging/Charger Station and Software also calibrates the Model GX-2001
by setting the zero and the span. To set the span, you will also need to use
a calibration kit, as described in the Model GX-2001 Operator’s Manual.
And while the Model GX-2001 is placed in the Data Logging/Charger
Station, its battery is recharged, provided the Model GX-2001 has been

The purpose of this manual is to explain how to use and set up the Data
Logging/Charger Station and Software. You will learn how to

• install and launch the software

• install the hardware

• down load data from the Model GX-2001

• view, print, and save data

• change data logging parameters

• calibrate the Model GX-2001
Before you get started, be sure to review system requirements in the next

section and to read “Overview of the Data Logging Software,” which tells
you what information the software provides and how it works.

WARNING: The Model GX-2001 detects oxygen deficiency and

elevated levels of oxygen, combustible gases, carbon
monoxide, and hydrogen sulfide, all of which can be
dangerous or life threatening. When using the Model GX­2001, you must follow the instructions and warnings in
the Model GX-2001 Operator’s Manual to assure proper
and safe operation of the unit and to minimize the risk of
personal injury.

Overview of the Data Logging
Software

The Model GX-2001 is a gas monitoring device for combustible gases, O
CO, and H
explosive limit (% LEL), O
as parts per million (ppm). The Model GX-2001 also records STEL and

TWA readings for H2S and CO.

S. It measures combustible gases as a percentage of the lower

STEL is an acronym for short-term exposure limit, and it shows the av erage
reading for H

time-weighted average, and it shows the average reading for H

S and CO during the last 15 minutes. TWA is an acronym for

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 inf ormation 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.

Interval T rend Data

Gas concentrations are logged over fiv e minute time intervals in the interval
trend data files. Events are saved when they occur. The data may be
viewed in table format, as seen in the following figure, or graph format.

Figure 1. Data View (Interval) Window Showing Gas Concentrations

The above information was obtained after the Model GX-2001 recorded
gas concentration lev els in the monitoring area. The unit w as then placed in
the Data Logging/Charger Station and the information stored in the unit’s
memory was down loaded to the computer. From the main window of the
Data Logging Software, the Data Icon was “clicked” (using the computer
mouse) to display the main Data window, from which this screen was
displayed.

For a given data session (interval data), there must be at least five
scheduled logs (every five minutes) for the data to be seen in graphical
form. If an interval data session has fewer than five scheduled logs, as in
Figure 1 above, the graph button is not available for selection.

Note that the data count shown when you have selected an interval data
file, as in Figure 1abov e , can be more than five if you have events, such as

scheduled log times.

form by clicking the Summary button.

Alarm T rend Data

In addition to the interval trend data the GX-2001 also saves a file which
describes the most recent event during a particular session.If an event
occurs, then an alarm trend file is saved separately from the data file , which
shows the reading 15 minutes before and 15 minutes after the event, with
the log time every five seconds.

When an event occurs and an alarm trend data file is saved in the GX­2001, this file remains in the unit’s memory until another event occurs.
When another event occurs , the alarm trend data file is ov erwritten with the
new event’s information.

Alarm trend data can always be displayed in either table and graph format.

Instrument Information and Calibration History

Calibration History on the most recent successful calibration for the GX­2001 is available on two screens: the Calibration History and the
Instrument Information windows. The Instrument Information window also
shows warning lev els and alarm lev els along with STEL and TW A readings .
Both windows, with sample data, are shown on the next page.
