6.8 Current output
Two voltage outputs and one current output are available simultaneously, but only one of them
can be finely adjusted. The adjustment accuracy of the remaining outputs can deviate by up to
0.2%. The current outputs are derived from the 10-V voltage output. A range of 0 ... 20 mA or
4 ... 20 mA can be selected. There is a mathematical relationship between the current and
voltage outputs: 0 V correspond to 0 or 4 mA, while 10 V correspond to 20 mA.
Note: Only positive voltages can be converted to equivalent currents.
Note: Negative voltages result in a current of zero.
When calculating the gain and setting the zero point of the device, proceed as though the 10-V
range needs to be calibrated, but measure the current output by the device. If an ammeter is not
available, you can alternatively measure the voltage at the 10-V output and then convert it into a
current value.
Calibration and adjustment are performed basically as in the case of the voltage output.
The switch settings are described in Chapter 4.1.3 titled Meaning of the DIP switches Page 13.
