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 (O2), carbon monoxide (CO), and hydrogen sulfide (H2S) simultaneously. The Model GX-2001’s compact size and easy-to-use design makes it ideally suited for a wide range 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.
System Requirements To use the Data Logging/Charger Station and Software, your personal computer must meet the following requirements: • Operating Systems: Windows® 95, Windows® 98 SE, Windows® ME, Windows® 2000, or Windows NT® 4.0 • Processor: IBM® compatible PC running Pentium® 2, Pentium® 3, or Pentium® 4 processor, or equivalent processor.
Interval Trend Data Gas concentrations are logged over five 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. Gas concentrations Time log (date and time) Provides summary data Warning levels Figure 1. Data View (Interval) Window Showing Gas Concentrations The above information was obtained after the Model GX-2001 recorded gas concentration levels in the monitoring area.
the Model GX-2001 going into and out of alarm, but you may not have five scheduled log times. The information on the previous page can also be displayed in summary form by clicking the Summary button. Gas concentrations Warning levels Time log (date and time) Figure 2. Data View (Interval) Summary Window Alarm Trend 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.
The following figure shows a sample graph of the four target gases, an alarm event, and the concentrations of two target gases during the alarm event. Alarm event and gas concentration Time log Time intervals For interval data, for alarm trend zoom shows greater data detail of information relative to time Gas concentration Cursor function activated; move scroll bar to see gas concentrations over time Figure 3.

A Road Map of the Software The windows on the previous pages are accessed through the Download window of the GX-2001 Data Logging Software. The Download window is the starting point for all Data Logging Software functions, and it is the first screen displayed when you launch the software. The figure below shows the various screens that you can access when you click the icon buttons on the right of the Download window. Figure 5.
Installing the Software 1. Launch Windows®. 2. Exit from all applications and open windows. 3. Insert the GX-2001 Data Logging Software CD into your computer’s CD-ROM drive.

To install the GX-2001 Data Logging Software in the default directory (C:/Programs/GX-2001), click the Computer Icon.
Installing the Hardware 1. Launch Windows. 2. Connect one end of the GX-2001 serial cable to the serial (COM1) port of your computer. You can use any active COM port, COM1 through COM 4. 3. Connect the other end of the serial cable to the GX-2001 Data Logging/ Charger Station. GX-2001 Serial Port Charger/ downloading station Figure 7. Connecting to the Serial Port on the Data Logging Station 4. Plug the GX-2001 Data Logging/Charger Station. Power cord into an AC wall socket.
Down Loading Data from the GX- 2001 You have the option of down loading data manually or automatically. If you down load information using the automatic feature, click the checkbox, “Automatic Download,” in the Download Window before placing the Model GX-2001 in the Data Logging Station. Remember that the Instrument Information screen will remain blank after Automatic Downloading is selected. Click here for automatic downloads Figure 8.
4. Press the Mode/Power button on the Model GX-2001. “Conn” displays on the Model GX-2001 LCD and “GX-2001...Connected Successful.” displays in the Download area of the Download window. 5. If you have selected “Automatic Download,” the downloading process begins automatically after you have placed the Model GX-2001 in the Data Logging Station and after you have turned on the unit by pressing the Mode/ Power button. 6.
Download messages Use to download all data Instrument data Use to download subsets of the data Clear data button Figure 11. Download Messages in the Download Window 8. You can view, print, or save the downloaded information. Or you can delete all the data in the Model GX-2001 by clicking the “Clear Data” button. WARNING: If you click the Clear Data button, all data is erased in the Model GX-2001, but not in your computer’s memory.
Viewing, Printing, and Saving Data You can view instrument information, interval data, alarm data, and calibration history. Note that you can only print and save interval and alarm data. Viewing Instrument Information To view instrument information, click the Instrument Information button on the Download window. The Instrument Information window displays. Remember that you cannot save or print this information. Figure 12.
Viewing Interval and Alarm Data To view interval and alarm data, click the Data button on the Download window. The Data window displays. Double-click to see the data files Check to organize files Figure 13. Data Window To see the data, do the following: 1. Double-click the GX-2001 icon in the Data area of the Data window to see the files holding the interval and alarm data. 2. To view interval or alarm data files (not the actual data), click the interval folder or the alarm folder, respectively.
3. Next double-click a file to view its contents, or click the View Data button. 4. When viewing interval data, you can see the information in a table format, graph the data if there are more than five scheduled data points, view the data in summary form, or view the events only. Data that has been graphed shows log time, gas concentration levels, and alarm events. Interval Data Interval Data with Summary Figure 15.
5. When viewing alarm data, you can see it either in table or graph form. Click to print data Click to transfer data to a file Click for a summary of the data Zoom level Cursor feature Figure 16. Alarm Data in Graph Form 6. In graph form, five or more events are required. When viewing interval trend or alarm trend information in graph form, you have several options: • You can choose which gas you want to graph • You can choose the zoom level, or time interval, on the graph.
• Note that the Cursor feature (applies to both interval and alarm data files) allows you to display the log time. As you use the scroll arrow to move across the graph from left to right, readings at specific log times are displayed. 7. To go back and view other data, click the Data button on the Download window.

When you delete Calibration History files, the Data Logging software asks you for a password. The password is when the software is first installed is rki. It is possible to change that password, as follows: 1. Right-click a file you want to delete. The “Please Input Password” screen displays. 2. Click Change Password. 3.
Changing Data Logging Parameters To change how data is displayed in reports and to make settings changes to the Model GX-2001, click the Set Button on the Download window to display the Set window. After you have entered your changes, click the Update button to upload the new information to the Model GX-2001. To upload new time and date information, click the Date Time Set button.
Using the Set window, you can specify the following parameters for the GX2001: • Choose the font type, style, and size for data reports in the Font window Figure 21. Font Window • Select the colors used to graph the various target gases in the alarm data report Figure 22.
• Make settings for the GX-2001 that affect at which gas concentrations a warning or an alarm is activated • Select STEL and TWA levels for the GX-2001 • Specify calibration intervals, in months, and change auto-calibration levels Figure 23.
Calibrating the GX-2001 The Data Logging Software allows you to set the zero and the span readings for the Model GX-2001 as part of the Set screen.These features require that a calibration adapter be installed on the downloading station. This adapter is under development. See the GX-2001 manual for calibration instructions. In the Download Screen, see Figure 6, there is a selection box called Automatic Calibration. Do not select this box.
