Customized Characteristic Curve; Introduction - Siemens SITRANS P Operating Instructions Manual

The diagnostic status of the simulation selected for each diagnostic is displayed in additional
tabs in the dialog box. The simulated diagnostics is indicated by a check mark in the check box.
End diagnostics simulation
You close the simulation in the "Diagnostics simulation" tab:
● To disable a specific diagnostic action, click "Off" (under the "Action" field).
● To end the diagnostics simulation, click on the "Disable" button.
When diagnostics simulation is enabled, diagnostic events of the real process are neither
recorded nor evaluated.
With activated diagnostics simulation, only the simulated diagnostics are displayed on the
device display.
Stop diagnostics simulation immediately after use:
● Click "Disable" in the "Diagnostics simulation" tab before you close the "Diagnostics"
● Alternatively, you can restart the device.

Customized characteristic curve

9.3.5.1

Introduction

For special applications, a customized characteristic curve is available.
This application is used, for example, for volume measurement in vessels with unusual shapes.
You define the relationship between inlet pressure and outlet current according to your user-
specific requirements.
You have up to 32 breakpoints available for this, which you enter using the engineering system
and display graphically.
Example
For measurement with the customized characteristic curve, you set the following values, for
example:
Damping value:
Lower range value:
Upper range value:
Application:
Unit:
Lower scaling point:
