You can use this menu to parameterize the analog outputs. This
input always refers equally to all components.
Analog output 0/2/4/NAM mA (start-of-scale value of analog output)
Analog output
Set value:
Range: 4 / 20 mA
Meas value neg: ON
84111
You can set the following start-of-scale values for the analog
current range in the 3rd line:
• 0 mA
• 2 mA
• 4 mA
• NAMUR
You can switch suppression of negative measured values on or
o in the 4th line. The "ON" option is preset, and means that
negative measured values can also be output. With a setting of
2 or 4 mA as the lower limit, values below this down to 0 mA can
therefore be output, i.e. negative measured values can be dis‐
played (live zero).
Analog output
Set value :
Range: 4 / 20 mA
Meas. value neg: OFF
84111a
If the output of negative measured values is switched o ("OFF"
position), the current output is limited to the start-of-scale value.
If 2 or 4 mA is set as the lower limit, the output is now indeed
limited to 2 or 4 mA. In the adjacent display, the start-of-scale
value of the analog current range is set to 4 mA.
The following tables represent the correlation between analog current outputs and measuring
range limits.
