* AST -- Auto Sensor Testing feature allows AE systems to control the sensor as a
pulser and a receiver at the same time. It can therefore characterize its own condition as well as send out a simulated acoustic emission wave that other sensors
can detect, so the condition of the nearby sensors also can be tested.
