4.3.2.6 DATA STAGE The Data stage displays the default results for the test template type. And you may select optional results from a list, also based on the test template type. The table shows the test method type and its associated primary and secondary results. The primary results are the default results always displayed. The secondary results are results that may be selected using the +Add Coefficient feature.
4.3.3 BREAK LIMIT TEST The Break Limit Test is used when you want a test for the maximum (peak) load and the distance at the maximum (peak) load. In a Break Limit test, the L1 software determines a break using the maximum load after a minimum load has been reached. Once the minimum load is reached, the L1 software continuously monitors the measured load and finishes the test when the maximum measured load drops by a percentage value you set. The percentage drop in load is called the % Drop value. For example, you specify the % Drop value as 10% meaning that a break is defined when the measure load drops by 10% from a previously measured peak load. The Break Limit Test reports the Maximum Load and the Distance at Maximum Load. The Break Test menu has three basic attributes: • Type • Minimum Break Target • % Drop Target • Speed

4.3.3.1 TEST TYPE The Test Option launches with the Type = Tension. Tension means you want to perform a Pull test, e.g. you want the crosshead to move in an upward direction. If you want to perform a Compression test (also called a Push test), change the Type to Compression. 4.3.3.2 MINIMUM BREAK LOAD The Minimum Break Load is a precondition step. This is the load that must first be measured before the L1 Controller begins to look for a Peak Load and a % Drop from Peak Load. The Minimum Break Load must always occur before the Peak Load otherwise a break will never be determined. The Minimum Break Load is used to counter samples that exhibit a high degree of noise in their load characteristic. This noise can result in a "noisy" load measurement where the load drastically swings from high to low values. This normally occurs at the initial stages of a sample being pulled/pushed to a break.
