Instrument Configuration
Instrument Configuration will modify the measured quantity display on the overview screen.
This instrument will always display Percent Hydrogen (%H
), and it is capable of displaying
2
three additional different parameters if desired. These include:
• Percent Dissociation (DA)
• Percent Ammonia (NH
)
3
• Nitriding Potential (Kn)
One additional parameter can be displayed along with Hydrogen by highlighting it and pressing
OK.
Percent Hydrogen
The percent hydrogen is the amount of Hydrogen that is being detected by the thermal
conductivity sensor inside the instrument. There are no additional calculations being
performed to this value.
Percent Dissociation
Dissociation is derived from the amount of Hydrogen in the sample gas. Flow rates must be
entered at the bottom of the screen to obtain a true %DA calculation.
Percent Ammonia
The amount of Ammonia can also be inferred from the Hydrogen value.
Nitriding Potential
The accurate calculation of Nitriding potential requires the flow rates of other gases that are
being introduced into the process. All of the flow rates must be in the same units and scaling.
SSi Portable Hydrogen Analyzer

Kn can only be calculated by entering the flow of Nitrogen (N
), Ammonia (NH3) and Dissociated
2
Ammonia (DA). These values are entered at the bottom of the home screen when Kn is
selected.

Minimum H2 for NH3 display
There may be times when the process is not active. During these times, the measured
Hydrogen value displayed on the screen will remain valid, but the calculated % NH
will not be
3
valid since it is based on the assumption that the known process gases are involved. In these
cases, it may be more desirable to hide the display of NH
known to be incorrect. This can be done by setting a minimum level of H
instead of displaying a value that is
3
that will be present
2
when the process is active. When the Hydrogen drops below this level, the instrument will know
that the process is not active and the NH
readings are not valid so it will not display NH3.

Output Configuration
There is one 4-20mA output that can be configured for any of the four parameters. The operator
can select the Source (H
, DA, NH3, Kn), the zero value (the value to be represented by 4mA) and
2
the span value (the value to be represented by 20mA).

Sensor Calibration
A proper calibration of the sensor requires two gases. The first gas should be pure Nitrogen or
Argon. This contains no Hydrogen, and is therefore referred to as the Zero Gas. The second
gas is the Span Gas. The Span Gas should ideally contain a quantity of Hydrogen similar to the
amount of Hydrogen in the process to be measured. The Span Gas should also include any
other gases that are present in the process gas in their respective percentages. The more
similar to the process gas the calibration gas is, the more accurate the calibration will be.
Performing a Zero Calibration
On the Sensor Calibration page, select Zero Hydrogen. Begin the flow of gas through the
analyzer using the flexible sample tubing assembly. The flow rate should be 1.5 to 2.0 SCFH as
measured on the flow meter in the lid of the case. The gas should not be under any pressure
other than the amount required to maintain the appropriate flow amount. The target Value is
shown on the screen. For a Zero Calibration, this will be 0.00 (the amount of Hydrogen in the
Zero Gas). The Measured H
Value can be seen at the bottom of the screen. When this value
2
comes to equilibrium, it will not be showing any upward or downward trends, only the slight
oscillation of the readings. This usually occurs in approximately 30 seconds. When the sensor
is at equilibrium, press the green
Calibrate button to perform the zero calibration. After the
Zero Calibration is complete, turn off the flow of gas and disconnect it from the enclosure.
Performing a Span Calibration
To perform a span calibration, select Span Hydrogen, and flow the span gas in the same
manner as the zero gas. The Target Value should be set to the exact amount of Hydrogen that is
in the Span Gas cylinder. Then the same procedure should be followed as the Zero calibration,
with the
Calibrate button being pressed after the readings reach equilibrium. After the Span
Gas calibration is complete, turn off the flow of gas, disconnect the cylinder from the enclosure.

Modifying Network Settings (Such as IP Address)
From the operating system screen, click
Double tap on the connection for the PH2 touch
If using the PH2 on a network, it may be necessary to modify network settings manually.One of
the most common reasons for modifying network settings is to manually assign an IP address
to the touch screen. If you are not familiar with IP addressing and network settings, it is
recommended that you first speak to your network administrator.
To modify the network settings, first shut down the interface using the Exit Program option (as
described in the
Exit Program section).
Once the PH
interface is shut down, you will see the operating system screen. The following

screen (in the example, it is called
“SMSC91181”). An Ethernet Driver settings
window will appear, giving you the ability to
specify an IP address. To do so, click the
“Specify an IP address” radio button. Then
enter an IP address manually.
SSi Portable Hydrogen Analyzer
Rev A

Make sure that the IP address does not conflict
with another IP address already assigned on
the network.
You will also need to add a Subnet Mask and a
Default Gateway. The subnet mask is usually
already determined for the network. A common
subnet mask is 255.255.255.0; however, check
with the network administrator to be sure. The
default gateway is usually the address of the
network router or other device that is
responsible for routing network traffic.
If you have questions about the specific network to which you are connecting the PH
, please
2
contact the network administrator.
Use with Touch Screen Manager
The PH2 is compatible with SSi’s Touch Screen Manager (TS Manager) software, which allows a
Windows-based computer to connect to and access data from the PH
use TS Manager, the Windows-based computer must be connected to the PH
touch screen. In order to
2
using an Ethernet

connection or a USB connection with Active Sync or Mobile Device Center. For more information
on using TS Manager, refer to the TS Manager manual available on the Super Systems Inc.
website:
http://www.supersystems.com
TS Manager is typically supplied with any new purchase of the PH
(“Manuals” link).
. If you need information on
2
obtaining TS Manager, please contact Super Systems Inc. at (800) 666-4330.
Changing the System Date and Time
The time and date that the PH2 screen software uses are based on the time and date of the
touch screen operating system. To change the time and date, first shut down the software as
shown in the picture below (also described in the Exit Program section). Once the software is
shut down, double tap on the time shown in the task bar at the bottom of the screen on the
operating system desktop. Change the date and time in the dialog box that appears.

Once the date and time are changed, the system registry should be saved in order to ensure
that any settings you changed are maintained when the touch screen is restarted or powered
down and powered up again. To save the registry, follow these steps.
1. Click on the Start menu, and then select Programs. Determine whether an Advantech menu
is present, such as the one shown in the figure below.
2. If an Advantech menu IS present: Select “Registry Saver” under the Advantech menu. A
