2.0 L3 Series Software

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.

Operating Fundamentals

2.1 Operating Displays Starrett L3 Series software is designed to operate on an all-in-one computer workstation with touchscreen capability. The interactive functions in our L3 Series software may be operated using touchscreen or using a standard mouse.

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

The L3 display views change based on the function the user is performing. All L3 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 Extensometer Indicator (E) The E symbol is used to display the sample elongation as measured by an external extensometer that is connected to the test frame. The elongation E, is always expressed as a percent value indicating the change in sample length from its original value prior to load being applied. NOTE Press the E symbol to zero/tare the elongation value.

2.1.1.4 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.

2.1.1.5 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.

2.1.1.6 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.

Load Cell Sensor Status View

When the Overload History displays an overload event with a date that doesn’t appear plausible, it indicates that a load cell overload occurred when the L3 software was not active, e.g. not launched during the overload event. A load cell sensor can be overloaded by an operator over-deflecting the sensor. Light capacity load cell sensors can be overloaded simply by improper handling. Load cell sensors can also be overloaded by improper use of the jog switch, which can cause the load cell to be forced against a hard stop.

2.1.1.7 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.

2.1.1.8 START/PAUSE/STOP Function The Controller window displays the START TEST-STOP TEST function. If an extensometer is used, the STOP TEST function also includes the ability to PAUSE a test turn. The START-STOP target operates identically to the Start/Stop push button on your MMS or MMD Series test frame. NOTE 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.

Manually Set Home before Start Test

Set Home Press to manually set home position prior to Starting a test

You may SET HOME manually before starting the test by pressing SET HOME. Or, you can setup your test to automatically SET HOME once the START TEST target is pressed.

Pre Test Setup Menu - Set Home Option (Yes or No)

Pause/Stop Test Press to pause a test to remove an extensometer from the sample

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.

2.1.1.9 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.

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.

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 L3 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 L3 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 L3 Series software. Many of these are shown in the examples in User Guide 5 - Analyzing Your Test Results .

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 16 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 16 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 L3 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.

L3 Data Definition Menu WHERE specifies where coefficient is displayed

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.

L3 Tolerance Definition Coefficient in red indicates an “out-of-tolerance” result

L3 Split Graph with Tolerance view Tolerance limits set for Distance at Maximum Load

starrett.com

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.

L3 Data Definition menu Coefficient algorithm for this Load Point is “Maximum”

L3 Data Definition menu Coefficient algorithm for this Load Point is “Minimum”

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. You may also establish a measurement between two existing coefficients. For example, you can measure the “delta” between two markers on the graph. Select the Delta tool and then move the scope handles until an existing marker changes its color to yellow, indicating an “anchored coefficient”. The “Delta” is measured between the two yellow markers. 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 two existing coefficient sets. They are highlited in yellow to indicate they are anchored coefficients- the Delta is being measured between these two anchored coefficient sets.

L3 Data Definition menu Shows a Delta measurement between two existing coefficients

The scope is a delta measurement between the coefficient DPt2 and DPt and is based on the distance units (mm). You may enter the values for the scope or move the scope handles along the axis until the existing coefficient markers change to a yellow color. When the marker is yellow, it indicates an “anchored coefficient”- used to measure another coefficient.

2.1.5 Runs List Each individual test performed in a test setup is called a Run. The Runs List is a numerically arranged list representing the number of tests that have been performed for the current test setup. A valid and successful Run is displayed with a black run number. If a Run has a failed tolerance on a coefficient, the Run number is displayed in red. If a Run was aborted due to an exception, the Run number is displayed in Red with an “x-out” indicating an invalid test.

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

2.1.6 Multi-Runs You may display the graphs of runs in your Runs List individually or collectively (overlays). 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 Multi-run tool appears when the graph displays multiple runs. This can be used to measure the deltas between the graph traces.

The alternate run #1 has a green dot. This corresponds to the green trace line.

The active run displays with a black trace. The black dot indicates this is the active graph trace.

2.1.7 Using Archived Runs for 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. 2.1.7.1 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.

Archive Test Runs appear in the Runs List with a Prefix “T”.

2.1.7.2 Importing an Archived Run Selecting the Archive function will open the Archive within the Metlogix directory, or where you have the Archive directory mapped to on your network. To import an archived test run, select a run from the list. You may select more than one. The selected run does not need to be from the same test setup either. NOTE You may select any test run from the Archive directory. The selected test run does not have to have been created using the test setup associated with the active test runs.

Select ARCHIVE function. Opens the Archives sub-directory. Select the test runs you want to import. Select Open.

2.1.7.3 Analyzing with an Archived Run When an archived test run is imported to your active Runs List, the graph and data that make up the graph are copied to your L2 Plus system. You can then use your measurement tools to take new measurements. Or, you can use the measurements from your current active test runs to compare results with historical runs. It may be necessary to re-measure results in the archived Run. Normally, when the archived Run is imported, the results associated with the current test Runs are automatically calculated and displayed with the archived Runs graph. NOTE When importing an archived Run, the archived Run may first show “XXX.X” for its coefficients. You may need to “re-link” the archived Run. You may do so, by simply choosing one of the active test runs, and then the archived run while in Multi-view.

Run #1 from Batch ID A136 2 is from the active Runs List. This graph is displayed in black.

The archive run is T-1 and has a green graph trace.

2.1.7.5 Removing (Deleting) an Archived Run Remove the archive test run using the delete function on the display view. When the archived test run is deleted, it is deleted from the Runs List. The archived test run is not deleted from the source Archive directory. NOTE

2.1.7.4 Statistics using an Archived Run Statistics may be re-calculated to include your Archived Run. You must select the archived Run with any of the active Runs you want statistical calculations for. If the archived Run is not selected, its measured results are not included in your statistical results. Only the results from your active Runs List will be used to calculate statistics. NOTE An imported archive test run does not affect the statistics in your active test. If you want to include the archived test run in your statistical calculation, you must use the multirun function and select the runs you want used for statistical calculations.

When you delete an archived run from a display view, the archived test run is removed from the Runs List. It is not permanently deleted from the Archive directory.

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: • Stress x Strain • Stress x Time • Strain 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. NOTE Certain coefficients may not be visible on a particular graph format.

Change the graph format by selecting the tab. • Stress x Strain ( σ x ϵ ) • Stress x Time ( σ x T) • Strain x Time ( ϵ x T)

The coefficient for modulus is displayed on a Stress x Strain graph, but not on the other forms because the modulus algorithm does not apply to Time graphs.

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 runs that are displayed in the graph.

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.
