Accessing a Common Database

The GX-2012 Data Logger Management Program stores downloaded data
in a database file. This database file is automatically stored on the
computer’s hard drive in the same folder as the GX-2012 Data Logger
Management Program. In this configuration, a computer has access to its
own database but no other computer’s. Only data downloaded to that
computer may be viewed. If the database was set up on a network location,
multiple computers could access the same database. All computers
accessing that database could view all data that was downloaded from any
computer.

The GX-2012 Data Logger Management Program has the ability to map its
database along any other valid path to another file location. That file
location can be on the same computer or it can be on a network location.
Putting it on a network location allows multiple users to save data to and
access data from the same location. This allows access to instrument data
that was downloaded at another computer.

NOTE: Only one computer at a time may access the database, so only

one software installation mapped to a common database can be
running at a time. If two installations attempt to access the same
database, an error indication will occur when the second program
is launched.

To set up this new database path:

1. You must first determine where the database is going to be located and
make a note of that file path.

2. If the GX-2012 Data Logger Management Program hasn’t been
launched on the computer yet, you must launch and close the program.
This creates a GX2012.ini file that contains configuration settings.

Table 1 above lists the GX-2012’s and the Gas Tracer’s data logging
capacity for each interval trend time setting assuming no alarms or other
events. The interval trend time setting can be set using the Set Window
(see “Changing Instrument Parameters” on page 79).

Overwriting Data in the GX-2012 and Gas Tracer

The instrument’s Data Log Overwrite setting is factory set to On so that

when the instrument’s data logging memory becomes full, it begins to
overwrite the oldest interval trend data with new interval trend data.
Download data regularly to avoid over-writing data in the instrument before
it can be downloaded. The Data Log Overwrite setting is accessible in the
instrument’s Maintenance Mode. To set the Data Log Overwrite setting to

Off, see the GX-2012 Operator’s Manual or Gas Tracer Operator’s Manual.

When the Data Log Overwrite setting is set to off, the instrument will stop
saving data when its data logging memory is full.

The Data Log Overwrite setting applies only to interval trend data. All other
data, such as alarm trend data, event data, or calibration data, will continue
to be saved when the memory is full. If the maximum number of each of
these types of data has been reached, the oldest data will be overwritten.

The instrument logs seven types of data files: bump test data, calibration
history, bar hole data, interval trend data, alarm trend data, snap log data,
and event data.

You can view, print, and export (save to a file) each of these types of data
files. All of these types of data files can also be deleted. The deleting of
files is password protected and is described in “Deleting Data in the Data
Window” on page 65.

NOTE: If the GX-2012 Data Logger Management Program database is

on the user’s computer (default setting), data will only appear for
instruments downloaded to that computer. If the database is on a
network, data will appear for all instruments downloaded to that
database. See “Accessing a Common Database” on page 19 for
more instruction.

All the data, other than the most recent calibration and bump test
information that is accessible in the Last Calibration Window, can be
accessed in the Data Window. The Data Window is accessed by clicking

Bump Test Data

The instrument is capable of saving information for up to 124 of the most
recent bump tests and calibrations combined. This bump test history is
retrieved by the Data Logger Management Program when data is
downloaded from the instrument using either the Complete Download
download command or the Download Logger Data download command.

Instrument bump test information is also available in the Last Calibration
Window. The information regarding the most recent successful calibration
and bump test for each downloaded instrument along with whether or not
an instrument is due for calibration or bump testing can be accessed using
the Last Calibration button on the right side of the program window. See
“Last Calibration Window” on page 70 for a complete description of the
information that can be accessed by the Last Calibration button.

All downloaded bump test data for all downloaded instruments is available
in the Bump Test folders in the Data Window. This information is saved in a
Bump Test Folder that is located in an untitled folder for each instrument.
The bump test files are differentiated by instrument. The bump test
information available here is more comprehensive than that in the Last
Calibration Window. The bump test information for all bump tests
downloaded, whether successful or not, is saved instead of just the most
recent successful bump test for each instrument.

To view, print, or export the bump test information for any instrument in the
database:

The instrument not only saves trend files which include logged data at
scheduled times, but also saves the 124 most recent alarm events and the
124 most recent trouble events. When an instrument is downloaded, the
GX-2012 Data Logger Management Program will retrieve these events
from that instrument and save them in alarm event files and trouble event
files for each instrument that is downloaded.

Alarm event files save the time, instrument channel, and alarm type of
every gas alarm event that occurs on a particular instrument. Warning (low
alarm), Alarm (high alarm), STEL, TWA, and overscale events are saved.

Trouble event files note the time, whether the event is an instrument
system failure or sensor failure and the specific type of failure. Dead
battery alarms and sensor failures are among the trouble events that are
saved.

Each leak check snap log consists of a Base reading and a Peak
reading. Base readings are shown in yellow and Peak readings are
shown in white. The User ID, Station ID, date/time, and methane
reading are shown. The methane reading is based on a 5000 ppm
scale. It does not matter what the display range was set to when the
gas reading was taken. The actual gas reading will be displayed up to
5000 ppm. If the concentration was over 5000 ppm, OVER will replace
the gas reading. If the Gas Tracer’s CO Display in Leak Check Mode
setting was turned on for operation, the CO reading will not be shown
in this screen because it is not saved.

Interval Trend Data

Average gas concentrations over the user defined interval trend time are
logged in the interval trend data files. The interval trend time can be set in
the Set window. See “Changing Instrument Parameters” on page 79. It can
also be set in the instrument’s Maintenance Mode. See the GX-2012
Operator’s Manual or the Gas Tracer Operator’s Manual for instructions to
set the interval trend time. Events such as gas alarms or sensor failures
are saved in the interval trend data file when they occur.

When the user ID of the instrument is changed during operation, a new
interval trend file is created. When the station ID of the instrument is
changed during operation, is it shown as an event in the interval trend file.
A new interval trend file is not created for a station ID change done during
operation.

An interval trend data file is created and saved in the instrument when the

instrument is turned off. The serial number, user ID, and station ID that are
entered in the instrument when it is turned on are saved for the

corresponding interval trend file. If the instrument’s serial number, user ID,
or station ID are changed in the Set window, any interval trend files that
result from subsequent operating sessions will have the new serial number,
user ID, or station ID saved in them.

The data may be viewed either in table format or graph format if at least 5
scheduled data points have been logged at the programmed interval trend
time. This does not include events. If an interval data file has fewer than
five scheduled data points, the graph controls are not functional and the
data cannot be graphed.

Alarm Trend Data

In addition to the interval trend data, the instrument also saves files that
describe the most recent gas alarm events. If a gas alarm event occurs,
then an alarm trend file that is centered around the event is saved
separately from the interval trend data files. It shows the readings up to 30
minutes before and 30 minutes after the event, with the log interval time
every five seconds. The gas readings logged at the alarm event time are
highlighted in red and the gas readings logged every 5 seconds around the
alarm event are the peak (minimum for oxygen) readings for the previous
five seconds. If the instrument has not been on for 30 minutes before the

Viewing, Printing, Exporting, & Deleting Data in the Data Window • 59

is turned off less than 30 minutes after an alarm event occurs, the data file
will only have logged data until the unit was turned off.

NOTE: If you are operating your instrument in Inert Mode with the

oxygen alarm pattern set to H-HH, the maximum reading for the
oxygen channel will be saved every 5 seconds instead of the
minimum.

The instrument saves up to 8 alarm trend files. When an alarm event
triggers an alarm trend file to be saved, subsequent alarm events must
occur 15 minutes after the previous triggering event in order to trigger the
saving of another alarm trend file. If 9 alarm trend files are already saved in
the instrument’s memory, the oldest alarm trend file is overwritten when a
new alarm trend file is saved. Alarm trend data can always be displayed in
either table or graph format.
