5.2 Programming with the SAP-200 Display Module The EchoTREK should be adjusted to the process by programming the parameters. The SAP-200 Display Module can be used to display the parameters during programming and measurement values during measurement. The SAP-200 supports two separately accessible programming modes representing 2-layers of programming complexity, depending on user choice. -
