6.3 COMPRESSION BREAK LIMIT The L2 controller can be used to perform a break test.
During a break test, the sample is pulled until the measured load drops (either by a % from peak or by a specific load value), which indicates a break event. Whenyouconfigureabreak test,youspecify theBreak%.This is thepercentage drop in load from a measured peak load. For example, if the measured peak load is 100 lbf, and the Break % = 20%, the break load = 80 lbf. Another method for defining the break is to specify a Break Drop. Using the same 100 lbf peak, if my Break Drop = 20 lbf, the Break Load = 80 lbf. The Minimum Break is the measured load that must first be achieved before the system starts looking for the break event. The minimum break protects against false break events in samples that exhibit significant load changes when under stress, e.g. peel tests. • Select the Compression symbol. • Select the Compression Break symbol. • Enter your Break % (percentage drop from the peak load) • Enter the Minimum Break value. • Enter the Test Speed.
ENTER THE BREAK %. The Break % is the percentage drop in the measured load from a previously measured Peak Load. When the load drops by this percentage, the L2 software determines the Break Load. Before a Peak Load or Break Load can be determines, the sample must FIRST exceed the Minimum Break Load you establish. You are required to enter the Min Break to counter samples that may exhibit significant load changes during their intial tension.
ENTER THE MINIMUM LOAD FOR THE BREAK. This is the load value that must FIRST be met before your L2 software begins to look for your Break % Drop Min Break is a "precondition" that must happen FIRST before the load detection begins.
Enter the Test Speed.
