Analysis Tool Symbols TOOL Description
Work or sometimes referred to as energy, is a characteristic of resilience or the ability of the material being tested to absorb energy. The Work algorithm calculates the area beneath the load-distance curve.
Work Tool
The Delta tool is used to measure or compare the differences between two variables. These variables can be load or distance. The Delta tool is ideal for creep and relaxation testing or on applications where you simply want to measure the change within a scope range. Break testing identifies when the material fractures or ruptures and provides a curve that can be used to identify the maximum load or distance prior to the break event. Break tools are used to find the point where a break occurred using two methods: % Drop after a maximum or using a load change rate using a slope.

Break Tools
The % Drop method first looks for the maximum load first. Once the maximum load is determined, the algorithm next looks for a % drop in load. So, if the maximum load was measured as 100N, and the load dropped to 80N, that is a 20% drop in load.
Break (% Drop)
The Break Rate algorithm looks at the slope along the load-distance curve to determine the break point. The Break Rate rep- resents the slope used to find the break point along the curve. The Break Rate is the load/distance rate on the curve. A Break Rate of 10.000 will look for the point after the maximum load where the rate of 10N/mm occurs. The Multi-Run mode performs as a graphical statistical analysis by comparing runs to one another using the graph and special Multi-Run graph analysis tools. With the Multi-Run tools selected, you can now perform the following: • Find the Delta between multiple runs • Find the Minimum results between multiple runs • Find the Maximum results between multiple runs • Find the Average result between multiple runs

Multi-Run Tools
The Multi-Run Delta is used to measure, calculate and display the delta between the graphs of multiple test runs using the run with the greatest value and the run with the lowest value. You may measure the delta based on load or distance.

The Multi-Run Minimum tool for multiple run analysis is used to find the test run with the lowest value from all data streams of all runs that are displayed together.
Minimum
The Multi-Run Maximum tool for multiple run analysis is used to find the test run with the greatest value from all data streams of all runs that are displayed together.

The Multi-Run Average tool for multiple run analysis is used to find the average of all test runs that are displayed together.

The Formula Tool is available when you purchase the L2 Plus Automation Builder application. It is optional. The Formula Tool lets you create arithmetic, trigonometric and logarithmic expressions.

Control Symbols CONTROLS Description
Choose to setup your system in Normal mode (Load x Distance). When in Normal mode, the crosshead position indicator is displayed as D.
Normal Mode
Choose to setup your system in Height mode (Load x Height). Height mode requires the user specifies a datum using the automatic datuming procedure. Test setups that will use Height mode, must have the system in Height mode BEFORE they create the test setup. When in Height mode, the crosshead position indicator is displayed as H. Choose between Slow and Fast jog speed when you select the Jog Speed symbol. When the pointer is displayed to the left, the jog speed is slow. When the pointer is displayed to the right, the jog speed is fast. The Load Cell symbol displays the full scale capacity of the current load cell connected to the test frame. Select the Load Cell symbol to display the model number, serial number, calibration information and view the sensor’s overload history. The Share symbol is used for manual exporting of data, results and graph images. The available export options vary depending on the display type you are viewing. You may display raw data, results, bit map image of your graph or you can export data to a clipboard for use with Word, Excel, etc.
