13.0 SCOPE Scoping is a post test data analysis feature where you can report results from within all of the raw data acquired for a step. For example, suppose you create a test setup using a tension to distance step. Your distance limit is 10 inches. Normally, you would report the load at 10 inches using the Load (L) coefficient. During this test, the system acquired all of the time-based raw data for load and distance from the Start Test event to the End Test event (10 inch limit). Suppose you wanted to know the load at 250mS after the start of your test or 5 seconds from the end of the test? Suppose you wanted to know the load values at 2 inch, 4 inch, 6 inch or 8 inch? Suppose you wanted to know the distance at 5 lbf? Scoping can be used to answer each of these questions. All steps have a beginning, an end and a duration. When a step is collecting data, the data is collected at the start of the step until the step's conclusion. The data collected during a step forms an array of data: loads, distances, and time. Most coefficients may use a scope. A list of the available coefficients, and whether or not they have a scope, is shown below. There are two types of scopes: a single scope and a scope range. A single scope references only one Step # while a scope range references a "Begin Step # and an End Step #".
13.1 SCOPE PROPERTIES Your scope is always associated with a step and with the coefficient related to the step. You are not restricted to the number of coefficients that can be assigned to a single step. In other words, you can have multiple results (coefficients) for a single step. Your scope has five basic properties: • Step Type • Step Reference • Scope Connector Type • Scope Value • Scope Units SCOPE TYPE A scope may be either a single scope or a scope with a Begin and End. The scope type for each coefficient is listed in the Table 13.
The coefficient selected for scoping is Lpeak. Lpeak has a Begin and End Step. Our example shows a Begin @ Step 4, which is where the peak load will be calculated from.
