Simulating the pressure sensor

By simulating the pressure sensor as a fixed value or a parameterizable ramp, you can
check the following functions:
● Trim
● Check the zero-point adjustment
● Reaction to violation of sensor limits
● Linearization
● Projection onto the working range
You can make the simulation value dynamic with a parameterizable ramp. The simulation
value then goes from a start value (v

Procedure
To simulate the pressure sensor, make the following settings:
1. Select pressure sensor simulation.
2. Set the simulation mode and the parameters:
– Simulation mode "Fixed" and parameter pressure value
– Simulation mode "Ramp" and ramp parameters
3. Transmit the settings from the program into the pressure transmitter.
