2.0 L2 Plus Series Software Operating Fundamentals

2.1.1 Controller Window The Controller window is multi-functional. It displays the dynamic measurements of load, crosshead movement, crosshead speed velocity and displays the current measurements with respect to their target settings. The Controller windows serves as your system’s “dashboard” supplying you with accurate measurement details of your tests and the individual measurements that comprise your test. The individual measurements supported by the Controller window are discussed in the following paragraphs.

2.1 Operating Displays Starrett L2 Plus Series software is designed to operate on an all-in-one computer workstation with touchscreen capability. The interactive functions in our L2 Plus Series software may be operated using touchscreen or using a standard mouse.

NOTE The minimum vertical pixel resolution of the touchscreen is 1080p.

The L2 Plus display views change based on the function the user is performing. All L2 Plus display views have a common layout consisting of a Controller window, Results window, Main window, header and footer sections.

2.1.1.1 Load Measurement Indicators (L) There are two indicators that display the load measurement from the attached load cell sensor. The current load measurement is displayed numerically next to the L symbol with its associated units or measure.

2.1.1.2 Crosshead Distance Indicator (D) The D symbol is used to display the crosshead distance traveled. If the test system is in Height mode, the D is replaced by H to represent the height of the crosshead from the established datum. The crosshead distance is the amount of crosshead movement from the start of the test.

NOTE Press the L symbol to zero/tare the load cell sensor.

NOTE Press the D or H symbol to zero/tare the distance or height value.

Additionally, the load bargraph displays the direction of load (tensile = above the center line and compression = below the center line). The load bargraph is intended to provide the user with an indication of the load being measured versus the full scale capacity of the load cell sensor being used. Color indication is used to represent the measured load versus the load sensor’s capacity as follows:

Current Height Measured by the encoder from the datum established by the user

Press to zero the height measurement

2.1.1.3 Crosshead Velocity Indicator During a test run, the crosshead velocity is indicated. Velocity is displayed for the current step being performed. Velocity may change during a test if you have specified a different crosshead velocity for a step. When automatically returning to the Home position, the crosshead velocity is returned at the maximum crosshead speed. Maximum velocity is an option in the System Settings - Motion Setup. Velocity is displayed with the unit of measure equal to the units of measure for the Distance (D) or Height (H) indicator.

2.1.1.4 Load Cell Status Indicator The Load Cell Status Indicator shows the full scale load capacity of the connected load cell sensor. The load cell symbol changes color to Yellow or Red depending on the sensor’s measured load versus its full scale capacity. Selecting the Load Cell Status Indicator displays the sensor’s characteristics, including its Overload History. All Starrett load cell sensors are compliant with IEEE 1451.4 (TEDS). These sensors are “plug & play”, e.g. your Starrett system automatically recognizes the sensor and its characteristics and performance specifications.

Load Cell Sensor Status View

NOTE Overloads may occur when the software is not controlling the test frame on which the load cell is installed. When this occurs, a record of the overload will display underneath the Overload History, but with a date which is not current. For example, the date stamp may have the year 1999. This means an overload occurred and was recorded by the load cell sensor, but not by the software since it was not controlling or communicating with the test frame.

L2 Plus Controller Window during an active test

2.1.1.5 Limits Indicator During an active test run, an indicator will typically appear above or below the measured value in the Controller view. For example, if the active test step is “go to a compression load of 25N” a limit indicator will appear above the measured load value showing the target load of 25N.

2.1.1.6 SET HOME Function Pressing the SET HOME target automatically sets the position of the crosshead as the home position, e.g. where the test is started from. You may press the SET HOME when manually starting a test, or you may configure your test setup to automatically SET HOME when you select the START TEST target. Setting Home allows the crosshead to automatically return to this exact position for the next test run.

2.1.1.7 START/STOP Function The Controller window displays the START TEST-STOP TEST function. This display target operates identically to the Start/Stop push button on your FMS or FMD Series test frame. CAUTION Starrett recommends that you use the Start/Stop push button to start or stop your test. This will help eliminate longer term issues on your touchscreen display where repeated touches can mare the display. The START/STOP function can be used to Start a Test, Pause a Test, or Stop a Test. If you are using an extensometer and want to remove it from the sample prior to sample break, you press the Start/Stop push button to stop (pause) the test. You can resume, by pressing the Start/Stop push button again. During an active test, the display will show STOP TEST. This is indication that the crosshead is active. CAUTION Tests performed at very slow speeds are difficult to distinguish whether or not a test is being performed and the crosshead is active. The crosshead is active when the STOP TEST label is displayed. CAUTION The Start/Stop push button features an LED indicator that shows the crosshead status. If the LED is displaying a solid GREEN, this is the same as START TEST, e.g. the crosshead is inactive and ready to test. During an active test, the LED displays a blinking RED indicating that the crosshead is active.

2.1.1.8 RETURN TO HOME Function The RETURN TO HOME function may be used manually or

automatically. The RETURN TO HOME function returns the crosshead to the SET HOME (start test) position after a test run is completed. Once the test run is completed, you may press the RETURN TO HOME target. The crosshead will return to its start position (SET HOME). If SET HOME was not selected or configured as part of the test’s Pre Test step, the RETURN TO HOME function is not available since no Home position was ever established.

CAUTION Care should be taken when using the RETURN TO HOME function for tensile tests. Prior to selecting the RETURN TO HOME function, it is recommended that the sample be removed from the test fixture.

In your test setup, you may use the Post Test step to configure your test to automatically RETURN TO HOME upon completing a test run.

Manually Set Home before Start Test

You must SET HOME for RETURN HOME to cause the crosshead to return to the start test position. Press RETURN HOME or use the RETURN HOME option in your Post Test step.

Start Test - Crosshead is INACTIVE

Stop Test - Crosshead is ACTIVE

2.1.2 Results Window During test operation, the Results window can be used to display your most critical results. Results are also called Coefficients. Coefficients are your measured results and are presented with a label that identifies the coefficient; the measured result for the coefficient; and the unit of measure for the coefficient. The Results window is also used to display the Data Definition Menu for a selected coefficient. The Data Definition Menu will be discussed in more detail in User Guide 5 - Analyzing Test Results.

NOTE The Data Definition Menu for a coefficient is used to determine where the coefficient gets displayed and what size the coefficient is displayed at in the Results window. This menu also allows you to rename your coefficient.

You can access the Data Definition menu for a coefficient by pressing the coefficient in the Results view. From the Data Definition menu, you have the ability to configure and set options for your this coefficient.

Use the WHERE function to designate what coefficient is displayed and “where” it gets displayed. This symbol shows to display the coefficient D@lmax on the Result view.

2.1.2.1 Coefficients/Results Results are also called Coefficients in L2 Plus Series software. Coefficients can be requested measurements prior to the test or as measurements after the test is completed, including derived and calculated results. NOTE

L2 Plus Series software gives you complete flexibility to get a result at any time from the acquired data for your test run. You can request a result before or after completing a test run. Here is a list of different coefficients that you can obtain using L2 Plus Series software. Many of these are shown in the examples in User Guide 5 - Analyzing Your Test Results .

NOTE L2 Plus Series software uses labels to represent coefficients. Labels may be renamed. Labels names are restricted to 8 characters.

Coefficient Name Coefficients have default names, which are abbreviations for the coefficient. You have the option of changing the name here. The coefficient name is restricted to 8 characters. Coefficients appear as “sets” in the Data Definition menu. For example, the coefficient for Load will also appear with the associated coefficient for Distance and Time. So, if the Point tool was used to find a particular Load on the graph, the Point too will also find the Distance at the point as well as the Time at that point. Coefficient sets are distinguished in the Data Definition menu by individual tabs. Changing the coefficient name in this menu only changes the name of this coefficient for this test setup. If you want to permanently change the coefficient name so it always appears with your preferred name, use the COEFFICIENT Settings function in the Main Settings section. NOTE Coefficient names may be up to 8 characters in length.

NOTE You can change the name globally using the main Settings menu. See User Guide 7 - Security and System Settings .

Coefficient TYPES for this measured result The “tab” shows the “active coefficient”. Change to another coefficient by select the tab for that coefficient.

Where to Display Coefficient Coefficients have three options as to where it may be displayed: • Results view • Data view • Graph view You can specify WHERE to display the coefficient by selecting the symbol that represents the view: Results, Data or Graph. The coefficient also has the option to be “pinned”. When a coefficient is pinned, the L2 Plus software automatically positioned the coefficient marker to the “best location”. When unpinned, you may move the marker to the desired location.

Select the WHERE location you want the active coefficient to display. A checkmark appears over the display location symbol indicating that the coefficient will be displayed at this view.

L2 Plus Data Definition Menu WHERE specifies where coefficient is displayed

starrett.com

Tolerance Limits Use the tolerance limits to setup pass/fail criterion for your coefficient. When tolerance is used, the value of the coefficient must equal or full within the range you created by the Limit 1 and Limit 2 values. If the coefficient result falls outside this range, the coefficient will display in red and will be identified in the Data view as a “failed result”.

Enter your tolerance limits to define your tolerance range. Results equal to or within the tolerance range will report as “Pass” results and will display in black text. Results that fall outside the tolerance range will report as “Fail” results and display in red text.

L2 Plus Tolerance Definition Coefficient in red indicates an “out-of-tolerance” result

L2 Plus Split Graph with Tolerance view Tolerance limits set for Distance at Maximum Load

Algorithm Options Coefficients have different algorithms or methods that you may select for your coefficient. The algorithm determines how the results is measured and calculated. For example, selecting the Min/Max/Avg tool will provide you with different algorithms for determining the Maximum or Minimum Stress. A single coefficient may be calculated in multiple methods/algorithms. The various algorithms are discussed in detail in User Guide 5 - Analyzing Test Results.

Select on the algorithm type available for the active variable. In this example, the active variable is LOAD and we switch from MAXIMUM to MINIMUM algorithm.

Select on the variable that the algorithm is being applied to. In this example, LOAD is the active variable. Selecting this target area will toggle the available variables between LOAD and DISTANCE.

Scope Limits All coefficients have a scope. The scope is the region within your data collected for the test, or shown on the graph that you are interested in. For many coefficients the scope limits may be from the START to the FINISH of the test run. However, you may enter your own specified Start and Finish limits, which could be based on a step in your test setup, or a time or associated with another coefficient. Scope limits have Units of measure that may be adjusted to find a specific result. For example, you want to know the load at 100mS after the maximum load. You can specify this using the Scope Limits. The Start is Lmax and the Finish is 0.01 S.s. Scope limits define the area/region you are interested in obtaining a result/coefficient. Scope is discussed in detail in User Guide 5 - Analyzing Test Results.

The specified Scope Range is using time. The start of the range is 5 seconds. The range finishes at 10 seconds. The Dlmax2 for this scope range is 8.283mm with the Lmax2 being 10.19N.

The active coefficient is Lmax2. The scope range is created starting at 5 seconds and finishing at 10 seconds. Notice the graph has changed to Load x Time. The two scope handles on the x-axis can be used to adjust the scope range. Or, you can simply enter the Start and Finish values into the Scope fields. The Scope operators may be @ (at a specific location), + (at a location AFTER), or - (at a location BEFORE). The units may be time, load, distance and can be changed by pressing onto the units targets.

The active coefficient is Lmax2. Its result is 10.19N. But because the WHERE for this coefficient shows not to display on Results, Data views or Graph views it does not appear on the graph or table.

2.1.3 Header Tool Bar The header tool bar is dynamic and depending on the function you are performing can change to include different icons of interest. During normal operation, the header will display the following: • Test Name • Graphical Analysis Tools • Equipment and Status Information • L2 Plus Main Menu Symbol

The Runs List mode is identified as in Single mode or Multi-Run mode by the green bar above the Runs List. When the bar is single, only one graph is displayed for the run you specify. Select the bar and the bar shows as a double bar indicating that you are now in Multi-Run mode. Select the Runs you want to display collectively in your graph view. Multi-Run mode operates in either the Full Graph view or Split Graph view. Color dots indicate the trace on the graph that corresponds to that Run number. NOTE The active Run in a multi-run view always has the black dot and the graph trace is also displayed in black. If you switch to a different run, that Run will now have the black dot and its trace will display in black.

Select the target to display a single run in the graph or multiple runs together.

The active run is highlited. The black dot indicates this is the active graph trace, which is being displayed in black also.

2.2 Graph Views There are a variety of different graph views available depending on the type of tests being performed. A graph is the most common method for analyzing results using the Graphical Analysis Tools. Using the graph, combined with these tools, you have an easy method for measuring and determining the results for your test. When tests are performed the following graph formats are available for viewing: • Load x Distance • Load x Time • Distance x Time Selecting the graph view is done be selecting the tab labeled with the respective graph view type. Graphs are automatically scaled to a “best fit” size. Graph axes are labeled and increments are calculated based on the data rate and the “best fit” size. The following sections will illustrate the different graph views available.

2.2.1 Load-Distance Graph View When no sample is characterized in the test setup, the test graphs will revert automatically to a Load, Distance, Time format. Stress and Strain will no longer be calculated. Select the L x D tab for load (y-axis) and distance (x-axis). 2.2.2 Load-Time Graph View You may display a load versus time graph. Select the L x T tab to view load (y-axis) versus time (x-axis). 2.2.3 Distance-Time Graph View You may display a distance versus time graph. Select the D x T tab to view distance (y-axis) versus time (x-axis).

Change the graph format by selecting the tab. • Load x Distance (LxD) • Load x Time (LxT) shown as “active” • Distance x Time (DxT)

2.3.1 Graph-Data Table Split View The split view displays the graph and data simultaneously. The individual features and functions of both the full graph and Data view displays are incorporated into this alternate view. You may use the multi-run function to overlay multiple graph traces and show their corresponding row data.

2.3 Data Table Views The Data view displays results in a tabular, spreadsheet-like format. Runs are represented by rows. The columns of the table represent the coefficients and other supporting information for the test. The Data view allows sorting of your data. Select the column header to toggle between ascending and descending order. When tolerances are used, the Data view displays failed tolerances in red and includes a tendency bargraph. NOTE Rows represent runs in the Data view. The row with the reference #1 is Run #1. There are no limits to the number of rows in a Data view. However, you may specify the maximum number of Runs in the Post Test step of your test setup. NOTE Columns represent coefficients/results. For every coefficient you are using, there is a representative column in the Data view. However, in the Data Definition menu for a coefficient, you have the option of displaying the coefficient in the Data view or not using the WHERE option.

2.3.2 Statistics View You have the ability to view basic statistical calculations using the Data view or the split view. Whenever data is displayed, selecting the sigma symbol will display the following statistics: • Minimum • Maximum • Range • Average • Standard Deviation • 6 Sigma If more detailed statistics are required for statistical process control, you may export the raw data in a .csv format and integrate with your SPC software application for more comprehensive analysis and documentation. NOTE Statistics are available from the Data view or Graph-Data split view. NOTE Statistics may be calculated for all runs in the Data view or you can specify only the runs (rows) you want.

You can adjust the viewing area by moving the header bar up/down. The graph is automatically sized.

The highlited row indicates the test run that is displayed in the graph.

Use the scroll bar to scroll up/down on your rows in your Data table.

Select the large sigma symbol to display the statistics for this test setup. Statistics are calculated on all test runs or the runs (rows) you select.

2.3.3 Tolerance View When tolerances are used, you have the ability to display your results with your tolerance information. Select the TOL function and your results, including pertinent tolerance information is displayed collectively. In the Tolerance view, each coefficient occupies a row in the data table. If a test run has five (5) coefficients, there will be five (5) rows for each coefficient.

NOTE You cannot display statistics and tolerance at the same time.

The coefficients are listed on a row for each test run. The tolerance settings are displayed for all coefficients where a tolerance has been setup.

The deviation bargraph displays where the result resides relative to the tolerance range- high or low or within the range. Failed results are displayed in red.

The Comment cells allow the operator to include comments on this result or the test run in general. Select the cell and enter your comment.

The highlited test run (#3) indicates which test run is being displayed in the Results view. If a split graph-data view was shown, the graph would indicated for #3.

2.3.4 Extra Coefficients L2 Plus allows certain information to be included in data table views that are not a measured result. From a Data view, the far right column contains a “+” sign. When you press or select this symbol, a list of “extra coefficients” are presented. Extra coefficients may be useful to include in your Data views. Simply select the coefficient and it will be added to your table. You can move the column or remove the coefficient by selecting or de-selecting from the list of values.

Select the “+” symbol to display extra coefficients that you may include in your data table. These coefficients are generally not a measurement result, but additional information to help identify your test results.

2.4 Exporting Data Result data may be exported automatically or on-demand using the Share function. Result data may be the results or the raw data of the entire test run from start to completion. You may also export certain information to the clipboard where it may be pasted into other applications, e.g. Microsoft ® Excel ® , Word ® , etc. And you have the ability to export image files in different formats, again for incorporation into other types of document applications. NOTE The factory default setting for Sampling Rate (Hz) is 100 (100 samples per second). The sampling rate may be set between 5 and 2000 samples per second. Higher sampling rates are prone to noise, so use care when specifying the rate. In most cases, 100 samples per second is sufficient. Lower sampling at 20-30 Hz is similar to what you would sample at using RS232. Data and information may also be exported using the Share function. The Share function appears in the footer tool bar. There are four basic share options when you select this symbol: • .CSV • Raw Data • Clipboard • .BMP Image

L2 Plus Metlogix Directory Exported information is saved to the Exports sub-diectory

Exports can be saved to the Export sub-directory within the Metlogix directory. Or, you may map the export to a location on your network using the File Settings.

.CSV Function When the .CSV function is selected, the results for the currently shown test run is exported to the Export sub directory in the Metlogix directory. NOTE When .CSV is selected using the Share function, a new file is created for the Export sub directory regardless of how you have configured Export Results in the Post Test step. Raw Data Function When the Raw Data function is selected using the Share function, a new raw data file is created for the Export sub directory regardless of how you have configured Export Raw in the Post Test step. Clipboard Function When the Clipboard function is selected, the displayed results are copied and saved to a clipboard where they may be pasted into another document, e.g. Word or Excel. The results only are saved.

2.4.1 Export Raw Data Raw data are all of the data points captured during a test run. When you set the Sampling Rate (Hz) in the Pre Test step, you have specified how many data points per second are being sampled and used to generate your graph and other measurements. When the Export Raw option is enabled, the raw data points for the completed test will be saved as a .csv file and saved to a directory that you designate in the Main Settings option. • Go to the Main Settings menu. • Select File Locations. • Select the Directory where you want your data saved to. NOTE When data is exported, it is exported in a .csv format.

In the Post Test step of your test setup, you may specify how this data is to be used by defining whether to export or not. Once you have designated a file location, you have two options on how to transmit the file to the location: Overwrite Data When Export Raw = OVERWRITE, raw data is exported to a .csv file. There is a single file and it includes all the raw data for that test run. CAUTION

When Overwrite is specified, all previous raw data for the previous run is over-written- it is permanently replaced by the new data.

Auto Number Data When Export Raw = AUTO NUMBER, raw data is exported to a .csv file. Each test run creates a new file and each new file is sequentially numbered for identification. NOTE

NOTE You may export up to 100,000 rows of data. A .csv file is created for each 25,000 rows from your test run. Up to four (4) separate .csv files are created if you are exporting 100,000 rows of data.

If you want to maintain the data for all test runs, use Auto Number. A separate file is created for each test run.

The maximum number of rows for data is 100,000. The maximum number of .csv files created for a test run is four (4).

Export Raw exports all of the data points from your graph based on the sample rate you set in Pre Test.

Export Results exports only the result data.

2.4.2 Export Results The Export Results function only exports the actual results data. No raw data is included. For every coefficient in your test, when Export Results is enabled, the results for your coefficients are exported in a .csv format to the File Location you specified in Settings. The default for Export Results is No- you are not going to automatically export the results. However, you may also specify the following types: Append Result Data When Export Results = APPEND, results are exported to a .csv file within the Directory you established prior to your test. There is a single file and each result is appended to the file as a new row. Overwrite Result Data When Export Results = OVERWRITE, results are exported to a .csv file. There is a single file and there is only one row of results. When a new test is completed, the data in the row is replaced with the new data. Auto Number Result Data When Export Results = AUTO NUMBER, results are exported to a .csv file. Each test result creates a new file and each new file is sequentially numbered for identification.

2.4.3 Export to Clipboard The export to clipboard function may be used to export your results data to an external document. From the current display, when the Share function is selected and then the Clipboard function, the Run number and all results displayed are saved to a clipboard where they may be pasted into another document, e.g. Word, Excel. NOTE When the clipboard is used, only the results are available for paste.

2.4.4 Export Image You can export an image of the currently displayed view using the Share function. The image is saved as a bitmap (.bmp) and applies to any views with a graph. When you export an image using the Share function, a .bmp image file is created and sent to a “clipboard” where you may paste the image

2.5 Offline Archived Run Analysis You may use the offline archive function to compare historical run results to current and active runs. Comparing archived runs with active runs should be performed using the Multi-view function. 2.5.1 Archived Test Runs When a Runs Limit is met, the oldest test run is moved to the Archive directory within your Metlogix directory. The archived run may then be opened using the Offline tool, which when selected, opens the Archive directory. From the Archive directory, you may select any test run. Selecting Open, the archived test run is placed in your active Runs List. Archived runs have a prefix “T”. For example, when you load an archived run onto your active Runs List, the first archived run will display was “T-1”. NOTE Any test run within your Archive directory may be impored to your active test and Runs List. Use care to make sure you are importing test runs that are associated with your current test setup and your current Runs List.

into another document, e.g. Microsoft Word or Excel. The .bmp image you create is not saved in a directory.
