3) The output signal can be adjusted to the set point by means of the knob. For this
purpose select the decade to be set using the arrow keys.
4) The output signal can also be increased incrementally in steps of 4 mA (25 %) using
the "25%" key.
5) The automatic step function and automatic ramp function allow automatic change of
the output signal.
For further information refer to the section "6.3.1 Automatic operation modes" of the
instruction.
6.2.2 Milliampere simulation
Figure 4 shows the way the CEP1000 is connected if it is supposed to function as a
2-wire transmitter with an external power supply. In this case the circuit is powered via
an external voltage source and the instrument just regulates the current in the circuit.
The regulating procedure of the output signal is the same as for the application as the
source of current in the milliampere range.
