The Profile, Graph, Data menus are dynamic and can change depending on which tab is selected. For example, the Data menu has operations that are specific to the selected data tab and will hide those specific operations when another non-data tab is selected.

16  ControLog Interface User Manual 3900 ControLog – Document Edition 1.7

File Menu

The File Menu allows the user to perform file specific commands. It allows the user to open previous data files, save all open data, close all open data or graph tabs, clear the status log, save the status log, print the status log, import uncertainty solutions and exit the application.

Open Data File

The Open file menu command allows the user to open previous data files for further review and analysis. Selecting this command will open a file dialog that will allow the user to browse to the desired location for the file to open. ControLog can open data saved in the follow type and format:

 Text File (Comma Delimited) (*.csv;*.txt)  Text File (Tab Delimited) (*.dat;*.txt)  Excel Workbook (*.xlsx;*.xls)  Backup ControLog File (*.backup)

Save All Data

The Save All file menu command allows the user to save all current open data tabs to individual files using a common name. This feature allows the user to quickly save multiple data tabs in a single operation. Selecting this command will open a save file dialog that will allow the user to specify the name and browse to the desired location to save the file. ControLog can save data in the following type and format:

 Comma-Separated Values (*.csv)  Text File (Comma Delimited) (*.txt)  Text File (Tab Delimited) (*.txt)  Excel Workbook (*.xlsx)  Excel 97-2003 Workbook (*.xls)

Example: If the user had two data tabs open, one called “3900 Data” and the other called “Agilent 34970A Data” and the user wanted to save the files as Excel Workbooks using the name “Test Data 10Aug09”. ControLog would

save two files to the user specified location with the follow names:

User Manual 3900 ControLog – Document Edition 1.7 ControLog Interface  17

Note: The 3900 must be shutdown or disconnected before this command becomes available.

Clear Status Log

The Clear Status Log file menu command allows the user to clear all current entries in the status log. The user will be asked to save the status log data before the log is cleared.

Save Status Log

The Save Status Log file menu command allows the user to save the current entries in the status log. Selecting this command will open a save file dialog that will allow the user to specify the name and browse to the desired location to save the file. All status log files are saved in HTML format (*.html).

Print Status Log

The Print Status Log file menu command allows the user to print the current entries in the status log. Selecting this command will open a print dialog that will allow the user to select the desired print options.

Import Uncertainty Solution

The Import Uncertainty Solution file menu command allows the user to import a HumiCalc with Uncertainty solution

into ControLog to define the uncertainty for the 3900 generator. Selecting this command will open an “Import

Uncertainty” dialog that will step the user through a two step import process. The 3900 uses two pressure ranges, one pressure transducer for saturation pressures below 50 psia and one pressure transducer for saturation pressures above 50 psia. These pressure transducers have different uncertainties and therefore require different HumiCalc solutions. Refer to your HumiCalc with Uncertainty reference manual for more information on creating uncertainty solutions.

18  ControLog Interface User Manual 3900 ControLog – Document Edition 1.7

The Exit file menu command allows the user to exit the application. If there is current data that has yet to be saved the user will be asked to save the data before the application closes.

20  ControLog Interface User Manual 3900 ControLog – Document Edition 1.7

Mode Menu

The Mode Menu allows the user to change the operating mode of the 3900. It allows the user to select between Frost Point, Dew Point, PPMv, PPMw, Percent Relative Humidity and Saturation Pressure. The current mode is indicated by a checkmark.

Saturation Pressure Control Mode

The Saturation Pressure Control Mode, Ps, is controlled at a constant value independent of any other pressure, temperature, or humidity value. While saturation pressure is held constant, all humidity parameters may vary.

Percent Relative Humidity Control Mode

The Percent Relative Humidity Control Mode or %RH Control Mode, %RH, is controlled at a constant value by varying saturation pressure, Ps, to compensate for any changes in saturation temperature, Ts, test temperature, Tt, or test pressure, Pt. While %RH is held constant, all other humidity parameters may vary. While in %RH control mode, the saturation temperature setpoint is automatically determined.

Frost Point Control Mode

The Frost Point Control Mode, Tf, is controlled at a constant value by varying the saturation pressure, Ps, to compensate for changes in either saturation temperature, Ts, or test pressure, Pt. While Frost Point is held constant other humidity parameters may vary. While in Frost Point control mode, the saturation temperature setpoint is automatically determined. Frost Point is independent of test temperature.

Dew Point Control Mode

The Dew Point Control Mode, Td, is controlled at a constant value by varying saturation pressure, Ps, to compensate for any changes in either saturation temperature, Ts, or test pressure, Pt. While Dew Point is held constant, other humidity parameters may vary. While in Dew Point control mode, the saturation temperature setpoint is automatically determined. Dew Point control mode is valid both above and below 0 °C, and Dew Point is independent of test temperature.

PPMv Control Mode

The PPMv Control Mode is controlled at a constant value by varying saturation pressure, Ps, to compensate for any changes in saturation temperature, Ts. While PPMv is held constant, other humidity parameters may vary. While in PPMv control mode, the saturation temperature setpoint is automatically determined. PPMv is independent of test pressure and test temperature.

User Manual 3900 ControLog – Document Edition 1.7 ControLog Interface  21

PPMw Control Mode

The PPMw Control Mode is controlled at a constant value by varying saturation pressure, Ps, to compensate for any changes in saturation temperature, Ts. While PPMw is held constant, other humidity parameters may vary. While in PPMw control mode, the saturation temperature setpoint is automatically determined. PPMw is independent of test pressure and test temperature.

Run Menu

The Run Menu allows the user to run the 3900 manually in purge mode or generate mode. The Run menu also allows the user to manually shutdown the 3900. The current run mode is highlighted.

Purge Mode

Selecting Purge from the run menu commands the 3900 into purge mode. The purge mode is generally used to prevent icing within the saturator and dry the saturator outlet after movement (transportation), storage (power off, no gas flow, etc.), after performing the saturator fill procedure, or while transitioning the saturator from higher to lower temperatures. When the system is not being used (power off, no gas flow, etc.), the saturator is closed off and the gas within is static. As thermal equilibrium is reached, water vapor will condense on all inner surfaces between the saturator outlet and the expansion valve inlet. The Purge mode counteracts this condition by allowing the carrier gas to flow in the opposite direction (expansion valve to saturator), drying the affected sections of tubing. This is a necessary preparatory step in any low humidity system. As a general rule, when starting from an ambient condition the system should be purged for 24 hours or more before attempting to operate in the Generate mode. If sufficient purge time is not allowed, condensed or trapped water will remain and system accuracy will suffer. Insufficient purge time is usually indicated by higher than normal (wetter than normal) indications of the device under test. These indications can be as little as a few tenths of a degree to as much as several degrees dew/frost point. Purging should also be performed while transitioning from warmer to colder saturation temperatures, and for approximately 5 hours after each 500 hours of continuous Generate mode operation. During Purge mode, both flow control and saturation temperature control are active, but saturation pressure control is disabled. The generator will attempt to achieve the indicated flow and saturation temperature setpoint values.

Note: When the saturation temperature is lowered, the fluid jacket surrounding the saturator cools in order to reduce the saturation temperature to its new setpoint value. As the saturator cools during this transition period, temperature gradients will exist between the inside of the saturator and the fluid jacket that surrounds it. The saturator outlet passes through this fluid jacket and will also exhibit temperature gradients along its length. If gas is allowed to flow normally through the saturator during this cooling period, the 100% humidified gas of the saturator may condense at the colder saturator outlet. Therefore, Purge mode should be used while cooling the saturator to lower temperatures. For this reason, the lowest humidity of a generation sequence or profile should be performed first. This low to high order requires that a Purge be performed only once prior to the generation sequence when cooling to the lowest saturation temperature. Then, as humidity values are increased, warming the saturator to higher values, further purging is not required.

Note: During Purge, no gas flows to the 3900 Conditioned Gas Outlet, and consequently no gas flows through the device under test if connected.

Generate Mode

Selecting Generate from the run menu commands the 3900 into generate mode. Generate mode is used to operate the system when exact humidity points or associated time intervals have not been determined, when data must be viewed and/or verified manually before proceeding to the next humidity point, or when more immediate control over the generated humidity is required. When in the Generate mode of operation, the system will control at the currently entered setpoint indefinitely. Any time a setpoint is changed, the system immediately begins adjusting to that new value, and will

User Manual 3900 ControLog – Document Edition 1.7 ControLog Interface  23

control at the new point indefinitely. Generate mode offers the flexibility to change the setpoint at any time, and does not force you into any set sequence or for any prescribed amount of time. The Generate mode also allows you to change the humidity control mode at any time. For instance, the system may be controlling Frost Point, then immediately switched to PPMv control mode.

Shutdown

Selecting Shutdown from the run menu commands the 3900 to shutdown. The 3900 may be shutdown while either generating or purging. When stopped, all system functions shutdown, pressure is vented, and the idle Control/Display screen is shown. During this idle time when the 3900 is stopped, gas is not flowing through the saturator. After extended periods of this idle time, the 3900 must be purged again prior to further use.

Profile Menu

The Profile Menu allows the user to Open, Save, and create new Auto Profiles. Auto Profiles give the user the ability to program a set of humidity and temperature test points and dwell times that will automate the 3900 generation process. The profile menu is dynamic and has operations that are specific to the profile tab. Specific operations will be hidden when another non-profile tab is selected.

The Auto Profiling feature is very similar to the Generate mode with the main exception that profiling relies on a predefined list of setpoints referred to as a profile. The user configurable profile is used as ControLog's road map during Auto Profile operation. It defines which setpoint values to go to, at what rate to go from one setpoint to another, and how long to stay at a specific setpoint before moving to the next one.

For more information, see Profiling.

3900 Parameter Tab

The 3900 Parameter Tab is the primary 3900 interface for the user and is visible whenever the 3900 is connected. From this tab the user can set setpoints, view actual values and view real-time uncertainty values. The 3900 Parameters tab is divided into two different areas; the Control Parameters and the Calculated Humidity Parameters.

User Manual 3900 ControLog – Document Edition 1.7 ControLog Interface  49

Control Parameters

The Control Parameters contain all the control and measurement parameters critical to the operation of the humidity generator. Notice that each parameter consists of a brief title, unit of measurement, and the data values for Setpoint, Actual, and Uncertainty as applicable.

All parameters are listed in an order similar to the generator's display with the exception of the first listed parameter. The first parameter on the Control Parameters is the active humidity control parameter. For instance, if ControLog were set to control the generator on dew point, then Dew Point would be listed as the first parameter rather than Frost Point.

In the Setpoint column is the list of the system controlled parameters. The Actual column lists the current values for each of the measured temperatures, pressures, and flow values. The Uncertainty column is a representation of the current uncertainty calculated in real-time by HumiCalc with Uncertainty using the uncertainties solutions imported into ControLog.

Changing Setpoints

To change a setpoint, click on the setpoint field that you would like to change. A Setpoint Entry box will appear and the title of the setpoint being changed will be underlined. For example, to change the Frost Point setpoint click on the Frost Point setpoint field.

Enter the new value into the Setpoint Entry box and select Ok.

50  ControLog Interface User Manual 3900 ControLog – Document Edition 1.7

Notice that the Frost Point setpoint field updates to the new value and the values in the Actual column begin moving toward the new setpoint.

The user can also drop down a Mini version of HumiCalc to help calculate the desired setpoint by clicking the drop down arrow on the Setpoint Entry box. For example, let’s say the user wants to calculate the required Saturation Temperature needed to generate a -50.0° Frost Point with a limited supply pressure of only 100 psia. Start by clicking the Saturation Temperature setpoint field and then click the dropdown at the right of the Setpoint Entry box.

User Manual 3900 ControLog – Document Edition 1.7 ControLog Interface  51

Next, select the known to be Frost Point and enter the know values for both Frost Point and Saturation Pressure.

Clicking the “Calculate” button will result in the calculated Saturation Temperature being placed in the Setpoint Entry Box and will close the HumiCalc dropdown.

Clicking “Ok” will close the setpoint entry and will send the setpoint to the 3900 generator.

Calculated Humidity Parameters

The Calculated Humidity Parameters contain values of the currently generated humidity calculated from current system temperatures and pressures. The calculated humidity parameters will also display a scrollbar as needed to allow for varying display sizes without loss of data.

%RH

Percent Relative Humidity (%RH) is the ratio of the amount of water vapor in a given sample to the maximum amount possible at the same temperature and pressure.

Frost Point

Frost Point Temperature is the temperature to which a gas must be cooled in order to just begin condensing water vapor in the form of frost or ice, and therefore only exists at values below 0.01 °C. When operating the system with indicated Frost Points above 0.01 °C, the values indicated are to be interpreted as Dew Points. However, Frost Point is not the same as Dew Point for values below freezing. Frost Point is independent of test chamber temperature.

Dew Point

Dew Point Temperature is the temperature to which a gas must be cooled in order to just begin condensing water vapor in the form of dew. Generally, Dew Point exists at temperatures above freezing. In many instances, Dew Point may actually exist at indicated values below freezing (super-cooled dew). However, it is important to note that Dew Point is not the same as Frost Point. Dew Point is independent of test chamber temperature.

PPMv

Parts per Million by Volume is a ratio of the number of molecules of water vapor to the number of molecules of the other constituents in the gas. Once established, PPMv is pressure and temperature insensitive, and is therefore independent of test chamber temperature and test chamber pressure.

User Manual 3900 ControLog – Document Edition 1.7 ControLog Interface  53

PPMw

Parts per Million by Weight is a ratio of the weight of the water vapor in a sample to the weight of the remaining constituents in the gas. Once established, PPMw is pressure and temperature insensitive, and is therefore independent of test chamber temperature and test chamber pressure.

Grains/lb

Grains per pound is a ratio of the weight, in grains, of water vapor to the weight, in pounds, of the other constituents in the gas. (7000 grains = 1 pound). Once established, Grains/lb is pressure and temperature insensitive, and is therefore independent of test chamber temperature and test chamber pressure.

Enthalpy

Enthalpy is a measure of the amount of energy required to change a gas from one temperature/humidity value to another. In application, enthalpy is not used as an absolute value, but rather it is the difference in enthalpy between two distinct points which are of interest. The datum point which results in zero enthalpy was therefore arbitrarily chosen at a test temperature of 0 °C and 0 %RH. Applying enthalpy is a matter of computing the difference in enthalpy between two or more distinct data points.

SVP@Tt

Saturation Vapor Pressure (SVP) computed at the Test Temperature.

SVP@Td

Saturation Vapor Pressure (SVP) computed at the Dew/Frost Point Temperature.

SVP@Ts

Saturation Vapor Pressure (SVP) computed at the Saturation Temperature.

F@Tt.Pt

Enhancement Factor at Test Temperature and Pressure.

F@Td.Pt

Enhancement Factor at Dew/Frost Point Temperature and Test Pressure.

F@Ts.Ps

Enhancement Factor at Saturation Temperature and Pressure.

Specific Humidity

Specific Humidity is a ratio of the weight of the water vapor to the total weight of the humidified gas. Specific Humidity is independent of test chamber temperature.

54  ControLog Interface User Manual 3900 ControLog – Document Edition 1.7

Absolute Humidity

Absolute Humidity is the weight of the water vapor per unit volume of humidified gas.

Dry Air Density

Dry Air Density is the partial density in weight per unit volume of only the dry air portion of a moist air sample. In other words, if the water vapor were removed from a fixed volume of air, the remaining dry air would exhibit this density.

Moist Air Density

Moist Air Density is the total weight per unit volume of a moist air sample. This density includes both the weight of the air and the weight of the water vapor.

Wet Bulb Temperature

Wet Bulb temperature is used in wet bulb/dry bulb aspirated Psychrometry, and is the temperature measured by a temperature probe whose tip is coated with water (typically by being covered with a wet sock). When aspirated at a constant air velocity, the wet bulb will cool due to evaporation of the water from the probe. The cool temperature, to which it equilibrates, is used in the calculation of humidity parameters.

Mixing Ratio by Volume

Mixing Ratio by Volume is a ratio of the partial pressure of the water vapor to the partial pressure of the remaining constituents in the sample. Mixing Ratio by Volume is independent of test chamber temperature.

Mixing Ratio by Weight

Mixing Ratio by Weight is a ratio of the weight of the water vapor to the weight of the remaining constituents in the sample. Mixing Ratio by Weight is independent of test chamber temperature.

Percent by Volume

Percent by Volume is a ratio (expressed as a percentage) of the partial pressure of the water vapor to the total pressure of the sample. Percent by Volume is independent of test chamber temperature.

Percent by Weight

Percent by Weight is a ratio (expressed as a percentage) of the weight of the water vapor to the total weight of the sample. Percent by Weight is independent of test chamber temperature.

Vapor Mole Fraction

Vapor Mole Fraction is the mole fraction of water vapor in a sample.

User Manual 3900 ControLog – Document Edition 1.7 ControLog Interface  55

Dry Air Mole Fraction

Dry Air Mole Fraction is the mole fraction of the dry air portion of a sample. The dry air portion is considered to be all constituents in a gas exclusive of the water vapor.

Supply Pressure

Supply pressure is the regulated pressure reading of the gas supply.

Note: The supply pressure value is gauge pressure.

Status Log

The Status Log tab contains chronological information about the system status, changes in operational modes, changes in setpoints, and runtime errors due to communication or mechanical difficulties encountered by the generator.

3900 Reported Errors

The 3900 Reported Errors tab only appears when the 3900 reports an error. This is a very important information tab because it reports 3900 system errors to the user. These types of errors can cause the 3900 to shutdown and require

immediate attention by the operator. The icon will be displayed to help draw the attention of the user to the reported 3900 errors.

System timing

The System Timing tab shows information about the current timing associated with the current operation such as

elapsed run time at current conditions. This window may be shown at any time by clicking the “Point Time” in the

status bar and is automatically shown when an Auto Profile is started. The tab gives detailed information on the Auto Profile as it runs. Elapsed and remaining Phase, Point and Total time are listed along with the detailed assurance conditions values and tolerances.

Graphing

Graphing is a powerful tool used to view previously recorded data or to monitor the current data in real time. The graph works hand in hand with the data tabs. While the generator is in operation, data tabs store the most recent data points from the connected devices at the desired interval. A graph can be used to create a visual picture of this stored data.

Graph operations can be accessed by two means, either by selecting the desired command from the graph menu at the top or by right clicking a graph tab and opening a context menu. The functionality of the commands are the same regardless of which method is used, but remember that the menu commands are dynamic and reflect operations that can be performed on the selected graph tab.

Note: ControLog has a limit of ten graph tabs opened at any given time.

Each graph tab consists of a two dimension plot across an X and Y Axis. The graph can be customized to display different point symbols, various line colors, a legend and a header.

This operation is available only when a Graph tab is selected.

User Manual 3900 ControLog – Document Edition 1.7 Graphing  85

The first two pages of the Graph Properties dialog are the same as the New Graph Wizard that is used to create new graphs. The Graph Properties dialog starts on the properties page from which the user can customize the look of each

graphed line as well as the chart itself. Clicking the “Back” button will move back to the data selection page where the

user can select which device items they would like to include in the graph. Clicking the “Next” button will move to the

Axis page where the user can specify the starting and ending X and Y axis values.

Y Axis Limits defines the maximum, minimum, middle and span values for the Y Axis.

The Maximum value defines the maximum Y value for the Y Axis. No values beyond this maximum will be displayed on the graph.

The Minimum value defines the minimum Y value for the Y Axis. No values below this minimum will be displayed on the graph.

The Middle value defines the middle Y value for the Y Axis. The Span value defines the amount above and below the middle value where the maximum and minimum Y

values lie. The Auto check box tells ControLog to automatically calculate the best Y Axis limits to encompass the current

data.

Note: The maximum, minimum, middle and span values are interrelated and changing any one value may result in another value automatically changing to assure all values mathematically equate.

X Axis Limits defines the maximum and minimum values for the X Axis.

The Minimum value defines the minimum date and time for the X Axis. No values below this minimum date and time will be displayed on the graph.

The Auto Min check box tells ControLog to automatically use the starting date and time for the current data as the X Axis minimum.

The Maximum value defines the maximum date and time for the X Axis. No values above this maximum date and time will be displayed on the graph.

The Auto Max check box tells ControLog to automatically use the last date and time for the current data as the X Axis maximum. The graph will constantly expand as new data points are recorded.
