The underpeak detector is typically set to stop a test before specimen failure. This minimizes the chance of

equipment damage that may result if the specimen fractures.

The following examples presume that the input to the underpeak detector is the DC controller's load transducer

feedback signal.

Determining underpeak levels from known test forces or displacements

To calculate the underpeak detector levels, the maximum and minimum test forces or displacements must

be known. If the test forces or displacements are known, the underpeak detectors should be adjusted to the

required levels in the operating procedure.

As with the limit detectors, the test configuration, test program, and fixturing are all factors to consider when

determining the underpeak detector levels. For example, consider the following test situation:

• The test will run in displacement control
