Overview
Note
Availability of the menu
This menu is only available if your device has at least one of the optional modules (2.1
and/or 2.2).
Behavior of analog outputs
The settings of the analog outputs are component-specific and depend on the currently set
measuring range.
You can define current ranges for valid measured values or set inverted current ranges. If
you use inverted current ranges, the assignment changes, for example:
0 ... 10 % CO ≡ 0 ... 20 mA
→
0 ... 10 % CO ≡ 20 ... 0 mA.
To ensure that negative measured values do not influence the further processing of
measured values, such negative measured values can be suppressed at the analog output.
The unchanged value is output on the device display.
In addition, you can define responses to specific device statuses. The following outputs are
available as alternatives in case of faults or with enabled function check:
● Display of the current measured value
● Display of the last measured value determined
● Display of the low or high limit of the analog output. The corresponding values are listed
in the table below in the section "Analog output range".
