Programming with Device Driver

This example shows the use of the DCS and MU components. Furthermore, the appli-
cation of the resistance measurement function with the DMM channels is shown in a
second test case. In this example, the device under test is connected with the front
connector of the TS-PSAM module. The bus coupling relays are not closed.
