3.3.3.2 Compress to Distance Step The Compression Distance Limit move causes the crosshead to move downward until it meets a distance setpoint. You define the distance target (setpoint), which is measured by the encoder during your test. Once this distance is achieved, the test or the step is completed.
• Select the Compression symbol • Select the Compression Distance symbol • Enter your Distance Target and Test Speed
These are the Exceptions for this step. An exception is an event. An exception stops the test. Exceptions are optional, but are recommended. Load Limit - If the crosshead moves to this Load and the Distance Limit has not be achieved, the test will stop. Break % - If the sample breaks the test will stop. A break is defined as when the load drops by this percentage value after a Minimum Load has been achieved and there is a maximum load measured. Min Break - This is the minimum load that must first be achieved before the system begins to look for a Break % drop in load.
Enter the target Distance Limit. This step will conclude when this distance is achieved.
Enter the Speed. This is the velocity the crosshead will move at to the Limit.
When Collect Data = Yes, the individual data points for this test step are acquired and saved for exporting. When Collect Data = No, no data points are collected or saved. The step is just a “goto” without any data collected.
