Basic Operating Description:

This instrument uses the measurement of Hydrogen to display % Hydrogen (H2), % Dissociation
(DA), and % Ammonia (NH3). When the flow rates of Nitrogen, Ammonia, and Dissociated
Ammonia are manually entered, the instrument can also calculate Nitriding potential (Kn).
When the instrument is turned on, it will display % H2 and %DA on the screen. To display
additional values (%NH3 or Kn), see the “Instrument Configuration” screen. The 4-20mA output
on the side of the case can be set up to retransmit the any of these measurements in whatever
range is appropriate for the application.

The home screen also displays the flow of N2, NH3, and D.A. These values can be entered by the
operator when the instrument is in the mode to evaluate Kn or %DA. This is discussed further
under the Instrument Configuration section. The Menu button in the bottom left-hand corner
will take the operator to the configurable options within the controller. The Chart button in the
bottom right-hand corner of the screen will display the data trend chart.

Chart

The Chart Display shows between 1 hour and 24 hours of process variable data on the screen
and can be scrolled back to view all of the data stored on the hard drive. The vertical timelines
change as the time changes on the screen.
The function buttons run along the bottom of the screen.

The Trend Lines button - - will allow the user to select or de-select the trend lines on the
trend chart to display. If the checkbox next to each trend line is checked, then that trend line
will be displayed.

The Datagrid View button - - will display a screen with the trend data in a grid format
instead of with trend lines. The trend data is shown in 1-minute intervals. Clicking on the OK
button on this screen will close the screen down and return to the Chart Display screen.

The Refresh button - - will refresh the screen’s trend data if the screen is not in real-
time mode.

The left green arrow button - - will move the chart’s view backward in time by the
specified chart interval.

The chart interval button - - will determine the number of hours displayed on the trend
chart. The options are: 1 Hour, 2 Hours, 4 Hours, 8 Hours, 12 Hours, or 24 Hours.

The right green arrow button - - will move the chart’s view forward in time by the
specified chart interval.

The blue arrow button - - will toggle real-time mode on and off. When in real-time mode,
the chart will automatically be updated once a minute.

Chart Sub Menu

There is a sub-menu available by putting a finger or a stylus anywhere on the chart and
pressing down for 1-2 seconds. The sub-menu will have the following options available: Zoom,
Restore, Add Note, Data, and Exit.

The Zoom option will allow the user to zoom in on a particular part of the screen. Once this has
been selected, the user can take a stylus or a finger and create a box around the desired data.
Once the user releases the stylus or finger, a zoom is no longer possible, and the user will need
to re-select the option from the sub-menu to zoom in again.

The Restore option will back out of any zoom options that have been performed and display the
chart screen as it initially was.
The Add Note option allows the operator to enter a note on the chart, similar to writing on a
paper chart. Pressing the Add Note option displays a screen where the operator can enter the
operator ID or initials and a note. The user has the option to enter a note using the operator
interface keyboard, where he or she will be able to type in the note; or the user can use the
Signature mode, which will allow them to write a note using a stylus.
The Data option will show the trend data as a data grid instead of the trend lines on a chart.

This functionality is exactly the same as if the user pressed the Datagrid View button - ­from the chart screen.
Exit will close out the sub-menu without selecting an item.
Pressing the red ‘X’ in the top right-hand corner of the screen will take the user back to the
status screen.

Exit Program

Selecting Exit Program will allow the operator to shut down the user interface. This can be
done by selecting Yes when prompted or No to return to the Menu list. If the user interface is
shut down, it will restart automatically when the power to the instrument is cycled.

Instrument Information

Instrument Information displays the default parameters of the Portable H2. This screen
provides information on any applicable revision levels and serial numbers. It also shows if the
instrument is logging data. There are no functions that can be performed on this screen; it is
for informational purposes only.
The Go Back button will return to the Menu list.

Instrument Configuration

Instrument Configuration will modify the measured quantity display on the overview screen.
This instrument will always display Percent Hydrogen (%H2), and it is capable of displaying
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.

Kn can only be calculated by entering the flow of Nitrogen (N2), Ammonia (NH3) and Dissociated
Ammonia (DA). These values are entered at the bottom of the home screen when Kn is
selected.

To change the display, click on Mode and press Edit. This will allow the operator to choose
between Hydrogen, Dissociation, NH3, and Kn for analysis and display. Select the appropriate
mode and press Ok to modify this option.

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 % NH3 will no be
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 NH3 instead of displaying a value that is
known to be incorrect. This can be done by setting a minimum level of H2 that will be present
when the process is active. When the Hydrogen drops below this level, the instrument will know
that the process is not active and the NH3 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 (H2, DA, NH3, Kn), the zero value (the value to be represented by 4mA) and
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 H2 Value can be seen at the bottom of the screen. When this value
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.
