In HART multidrop mode, the current is constantly 4 mA. This value
does not change even in case of failure.
Current output
▼
Characteristic: 4-20 mA
▼
Failure mode: 22 mA

Min. current 3.8 mA
In this menu item you simulate a user-defined level or pressure value
via the current output. This allows you to test the signal path, e.g.
through connected indicating instruments or the input card of the
control system.
The following simulation variables are available:
•
Percent
•
Current
•
Pressure (with pressure transmitters)
•
Distance (with radar and guided microwave)
With Profibus PA sensors, the selection of the simulated value is
made via the "Channel" in the menu "Basic adjustments".
How to start the simulation:
1. Push [OK]
2. Select the requested simulation variable with [->] and confirm
with [OK].
3. Set the requested numerical value with [+] and [->].
4. Push [OK]
The simulation is now running, with 4 ... 20 mA/HART a current is
outputted and with Profibus PA or Foundation Fieldbus a digital value.
How to interrupt the simulation:
→
Push [ESC]
Information:
The simulation is automatically terminated 10 minutes after the last
pressing of a key.

Basic adjustment
If the "Reset" is carried out, the sensor resets the values of the follow-
ing menu items to the reset values (see table):
