6.2 Basic operating modes

The CEP1000 has 4 operating modes for the mA range and one operating mode for
voltage measurement. The following text and figures explain different operating modes.

6.2.1 Milliampere source

Figure 3 shows a typical application, for which the CEP1000 is used as a source of
current for the range from 4 ... 20 mA for the instrument to be tested.
