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 gures explain dierent 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.

1) Turn on the instrument. As a standard the operating mode source of current in the

mA range is set.

2) Connect the instrument to be calibrated.

For the instrument to function as a source of current, the circuit must be

closed. In case of an interrupted circuit the LCD display "OL" is blinking

and indicating an overload or an interruption of the circuit.
