MicroGuard™ Features
The following summarizes the MicroGuard™ solution features.
• Application: The mobile application serves as an extension of
the GLA131 Series Microportable technology. It can display
various gases in real time through the application and can
assist in identifying methane and ethane emissions.
• Handle: The handle is designed for user comfort and to hold
both the Nautiz X6 hand-held device and wand in place while
surveying designated areas.
• Wand: The wand has been designed as an extension of the
analyzer input port with a collapsible feature for easy storage.
• Device: The Nautiz X6 hand-held device is a rugged Android
device, suitable for field testing and acting as the interface
for the mobile application.
• Inlet tubing: The inlet tubing connects to the GLA131 Series
Microportable and serves as an extension with the wand to
intake gas at the desired location.

7 Take the end of the wand (the other end has been attached
to the inlet of the analyzer) and secure it into the handle with
the screw. Unscrew the clip at the bottom of the handle to
loosen the clip.
The clip does not have to be unscrewed all the way.
8 Once loose, insert the wand and screw the clip until the
handle sits firmly.
You are now ready to begin using the MicroGuard™ mobile
application on the NX6.
Analyzer Power-On
Turn on the analyzer. Refer to GLA131 Series Microportable user
manual, document #3KXG167001R4601.

Figure 17 MicroGuard™ Network Configuration Schematic Diagram
4 Communications Configuration
Overview
Connection must be established between the MicroGuard™
software system and the GLA131 Series Microportable prior to
streaming data in the mobile application. Turn on the analyzer
prior to launching the mobile application.
Local Data Stream Configuration
Once the MicroGuard™ software system is installed, several
additional steps must be taken to ensure the various software
components are properly mounted and configured.
Network Communications Configuration
Network Map
Figure 16 illustrates the MicroGuard™ network configuration.
Only the Android device communicates with the analyzer
through Bluetooth. The analyzer does not communicate with
the internet, and all traffic to and from the analyzer is limited to
Bluetooth.
Security Configuration
System Ports
Bluetooth: Data streams from the analyzer to the mobile
application via Bluetooth.
The application requires access to the following TCP port on
the intranet: 20002 Websocket data stream from analyzer.
Ensure that this port is not blocked by any firewall software on
the intranet or internet.
ABB, Inc. bears no responsibility for security vulnerabilities
introduced by opening ports beyond that specified here.
System Services
The services provided by the MicroGuard™ solution include the
following:
• Bluetooth pairing from the NX6 and the analyzer to stream
data from the analyzer
• GPS to display maps and location
System Software
The MicroGuard™ solution does not require further software
installed beyond the mobile application.
Communication interfaces
In addition to providing a means for streaming data in real
time, TeamViewer can also be deployed for troubleshooting in
communication with Field Service.
Security Controls
The security configurations necessary for security controls is to
change passwords from their default value as instructed in the
initial launch of the mobile application.

5 System Software
Overview
The MicroGuard™ mobile application is a user-interface (UI)
software that displays real-time gas concentrations in
conjunction with maps displaying GPS location. Data files
generated by the application are stored locally on the android
device and can also be uploaded to your Google Drive storage
in real time. In addition to storing data, the application also
provides PDF data reports immediately following closing the
collection of data called a walk package.
• Header – displays analyzer and connection status:
– Overall analyzer status: Green with a checkmark indicates a
normal operating condition, yellow with an exclamation
mark indicates a warning state, and red with an X indicates
an alarm state. (See Figure 18.) If the status is yellow or red,
the pressure, temperature, or ringdown of the analyzer is
out of its normal operating condition: Check the analyzer
for specific details.
• Analyzer battery charge level status. A gray battery indicates
the application is waiting for a response from the analyzer for
the battery status (see Figure 19).
I M PO RTA NT!
The NX6 is not GMS certified with Verizon: It is
recommended to use a SIM card from AT&T or TMobile
because these are the only carriers certified with the NX6.
GMS certification applies to the use of Google applications.

other walk package settings, shut down the analyzer, and log
out of the application. Refer to the Application-Specific
Screens section for details.
• User location – current location.
• REC – select to start and stop recording of data collection.
Refer to the Recording Icon section for details.
• Measured gas in in parts per million (ppm) . For example,
figure 17 displays CH4 1.76 (1.76 ppm of methane.
• Time trace graph – displays a time trace graph of gas data
when data are being recorded.
Operational Overview
There are two user accounts for the mobile application: admin
and tech . These two users are designed so that the tech users
can survey areas using operational settings within the
application chosen by the admin user. Refer to the User
Management Roles and Privileges section for a list of what each
user has access to within the application.
The following is a sequential overview of starting, using, and
closing the MicroGuard™ application.
For details on starting the application, refer to the Software
Startup section.
For details on using the application features, refer to the
Application Level section.
1 Turn on the analyzer. Refer to GLA131 Series Microportable
user manual, document #3KXG167001R4601.

9 The Time trace graph below the map defaults to display methane (see Figure 17). If desired, go to Menu > Live Gas to toggle to
another target gas, if appropriate, before or during data collection (refer to the Live Gas section). Each gas has a user threshold
in ppm, as well. If you want to change these values, go to Menu > Settings > Threshold alarm (refer to the Settings section);
otherwise they will remain at their defaulted values. In order to do this with each gas, the gas must be toggled.
10 When finished collecting data, select REC to close the file and generate the PDF report.
NOTE
After selecting REC, the analyzer stops streaming data to the hand-held device, but continues to measure and record data.
11 To check the report:
• Select the Menu > Data packages > Walk Packages (see Figure 26). The easiest way is to sort by date in descending order and
note the files by timestamp.
• Tap the Report icon (see Figure 26): The PDF report automatically appears (see Figure 27). Continue scrolling through the page to
view the full scope of the report. This file can also be transferred to your computer to be viewed off of the hand-held device.

Each MicroGuard™ release will also have an SHA256 checksum associated with each APK. This guarantees the APK was not altered
by signature or by malware. See the release notes for each version’s checksum. The following process describes how to verify the
APK’s checksum.
• The update package download will be available to download via ICOS Support Service announcement.
• The package contains the user manual, release notes, and APK.
• The download link is password protected.
• In order to verify the APK was not altered, verification of the checksum is recommended.
Verify the APK checksum as follows:
1 Open Windows PowerShell and navigate to the location of the APK file. (i.e. cd /path/to/APK )
2 Run command Get-FileHash on the APK file (see Figure 33).
3 Verify the Hash shown in the terminal matches that of the APK version stated in the Release Notes (snippet shown below in
Figure 34).
4 Once the checksum has been verified, continue to install the APK. (Refer to Install APK File via USB .)
