For safety reasons, all simulation data may only be saved in the volatile working memory.
After a restart of the device, any simulation that was activated is deactivated again. You can
simulate the pressure and the current value of the analog output.

6.3.7.2 Simulation as fixed value
Description
Taking the physical unit of measurement into account, you can assign a parameter as a fixed
pressure value. While pressure simulation is activated, the pressure transmitter will not react
to changes in the process pressure. The current output value is set corresponding to the
required current or pressure.

6.3.7.3 Simulation with a ramp function
Description
You can select a ramp function for the pressure simulation. Adjustable start-of-scale and full-
scale values together determine the limits between which the simulation values with a rising
or falling tendency can move. The step width can be calculated with the step number, which
is also adjustable. You can specify the rate of rise of the ramp via the duration of the
individual ramp steps.
