The (measuring) range and the mA values (or V) of the analog outputs are defined in the main screen ‘Ana-
log outputs’. “Current” or “voltage” can be selected as the output signal via a pull-down menu.
One analog output is available. This mA output is freely adjustable. An appropriate measuring device has to
be connected to the respective output terminals for correct adjustment of the mA values.
To calibrate the analog outputs, select in the screen ‘Set calibration point’.
Now you can set the analog outputs with the help of the user interface as follows:
7.3 Analog Output
By means of the controller as depicted in Figure 34, you can increase the value (shift controller to the left) or
reduce the value (shift controller to the right). After setting the correct value, you have to click on the ‘Save’
button. Now the set value has been accepted by the program.
After adjustment of the output signals you now still have to specify the (measuring) ranges. The default set-
ting for concentration here is 4-20 mA, but a measuring range of 0-20 mA is also possible.
